What is the term for the rounded articular process of a bone that usually articulates with another bone?
Condyle
Epicondyle
Tuberosity
Head
The head of a bone is its rounded articular end that fits into a corresponding cavity on another bone to form a joint. Condyles are also articular projections but are typically found on the distal ends of bones and form part of a hinge or condyloid joint. Tuberosities and epicondyles are non-articular prominences where muscles and ligaments attach.
Which of the following describes the head of the femur?
It is located at the distal end of the femur
It serves as the attachment point for the iliotibial tract
It forms the lateral malleolus of the ankle
It articulates with the acetabulum of the pelvic bone
The head of the femur is the rounded, proximal portion that fits into the acetabulum of the hip bone to form the hip joint. The lateral malleolus is part of the fibula at the ankle and is not related to the femoral head. The iliotibial tract attaches to the tibia, not directly to the femoral head.
The head of the humerus fits into which part of the scapula to form the shoulder joint?
Coracoid process
Acromion
Scapular spine
Glenoid cavity
The spherical head of the humerus articulates with the glenoid cavity of the scapula to create the glenohumeral joint. The coracoid process and acromion serve as attachment points for muscles and ligaments and do not form the socket for the humeral head. The scapular spine is a prominent ridge on the posterior scapula, not an articular surface.
The head of a typical rib articulates primarily with which vertebral structure?
Lamina of the vertebra
Superior costal facet of a vertebral body
Spinous process of the vertebra
Transverse process of the vertebra
The head of a rib typically articulates with the superior costal facet on the body of the corresponding vertebra (and sometimes with the inferior costal facet of the vertebra above). The transverse process interacts with the rib tubercle, not the head. Spinous processes and laminae are parts of the vertebral arch and are not involved in rib head articulations.
Which of these bones does NOT have a defined head?
Femur
Humerus
Scapula
Radius
The scapula is a flat, triangular bone that does not possess a rounded articular head. The humerus, femur, and radius all have distinct heads that articulate with other bones to form joints. For example, the humeral head fits into the glenoid cavity, the femoral head into the acetabulum, and the radial head into the capitulum of the humerus and the radial notch of the ulna.
The head of the radius articulates with which structure on the humerus?
Olecranon fossa
Coronoid fossa
Capitulum
Trochlea
The rounded head of the radius fits into the capitulum of the humerus to allow the forearm to flex, extend, and rotate. The trochlea is the spool-shaped structure for the ulna, and the olecranon and coronoid fossae are depressions on the humerus for the olecranon and coronoid processes of the ulna during extension and flexion, respectively.
Where is the head of the ulna located?
At the proximal end of the ulna
At the distal end of the ulna
Midshaft of the ulna
Ulna does not have a head
The head of the ulna is found at its distal end near the wrist and articulates with the ulnar notch of the radius at the distal radioulnar joint. The proximal end of the ulna features the olecranon and trochlear notch, not a head. All long bones have heads except for certain flat or irregular bones.
Which statement best distinguishes a bone head from a condyle?
A condyle is non-articular, while a head is articular
Condyles are only found in the skull, while heads are in long bones
The head is a rounded articular surface at the end of a bone, while a condyle is a smoother, rounded eminence that articulates within a joint
The head is always smaller than a condyle
A head is the prominent, rounded articular surface at the end of a bone, typically forming part of a ball-and-socket joint. A condyle is a smooth, rounded eminence at the end of a bone that articulates with another bone, often in a hinge or condyloid joint. Condyles are articular, and both heads and condyles occur in many long and short bones, not just in the skull.
The surgical neck of the humerus is located:
At the distal end, near the condyles
At the junction of the diaphysis and metaphysis of the shaft
Between the head and greater tubercle
Just distal to the greater and lesser tubercles
The surgical neck of the humerus lies just below the greater and lesser tubercles, making it a common fracture site. The anatomical neck is directly adjacent to the head and is less frequently fractured. The distal end near the condyles is unrelated to the neck regions, and the junction of the diaphysis and metaphysis describes a broader area of the shaft.
Which joint classification best describes the articulation between the head of the femur and the acetabulum?
Hinge
Ball-and-socket
Saddle
Pivot
The hip joint is a classic ball-and-socket joint, where the spherical head of the femur fits into the acetabulum of the pelvis, allowing multi-axial movement. Hinge joints permit flexion and extension in one plane only, pivot joints allow rotation around a single axis, and saddle joints provide biaxial movement but lack the full range of a ball-and-socket.
The head of the fibula articulates with which part of the tibia?
Medial condyle
Lateral malleolus
Lateral condyle
Tibial tuberosity
The head of the fibula articulates with the lateral condyle of the tibia, forming part of the proximal tibiofibular joint. The medial condyle is on the opposite side, and the tibial tuberosity and lateral malleolus are different anatomical landmarks unrelated to this articulation.
A fracture at the surgical neck of the humerus can endanger which artery primarily supplying the head of the humerus?
Brachial artery
Profunda brachii artery
Radial artery
Posterior circumflex humeral artery
The posterior circumflex humeral artery wraps around the surgical neck of the humerus and is at risk in fractures at this site. The brachial and radial arteries run more distally in the arm and forearm, while the profunda brachii artery branches off more proximal and supplies the posterior arm.
During supination of the forearm, what happens at the head of the radius?
It moves inferiorly toward the wrist
It rotates within the radial notch of the ulna
It dislocates from the ulna
It glides posteriorly along the ulna
Supination involves the radial head spinning within the radial notch of the ulna while the distal radius crosses back over the ulna. It does not glide posteriorly or move inferiorly, and dislocation does not occur in normal movement.
In the talonavicular joint, the head of which bone articulates with the navicular bone?
Calcaneus
Cuboid
Navicular itself does not articulate with its own head
Talus
The head of the talus presents an articular surface that fits into the concave navicular bone to form the talonavicular joint. The calcaneus articulates with the cuboid bone, and the cuboid does not articulate with the navicular in this joint. The navicular does not have a separate head structure.
The fovea capitis is a depression found on the head of which bone?
Humerus
Tibia
Radius
Femur
The fovea capitis is a small pit on the medial aspect of the femoral head where the ligamentum teres attaches, securing the femur within the acetabulum. Neither the humerus nor the radius or tibia possess a fovea capitis. This feature is important for hip joint stability.
A condition characterized by displacement of the epiphysis at the head of the femur is known as:
Legg-Calvé-Perthes disease
Coxa vara
Slipped capital femoral epiphysis
Genu valgum
Slipped capital femoral epiphysis occurs when the proximal femoral epiphysis (capital epiphysis) slips relative to the femoral neck, often during periods of rapid growth in adolescents. Legg-Calvé-Perthes disease involves avascular necrosis of the femoral head, and coxa vara refers to a decreased neck-shaft angle. Genu valgum is a knee alignment issue and unrelated to the femoral head.
Which artery provides the main blood supply to the head of the femur in adults?
Obturator artery
Lateral circumflex femoral artery
Medial circumflex femoral artery
Femoral artery
In adults, the medial circumflex femoral artery sends retinacular vessels along the femoral neck to supply the head of the femur. The lateral circumflex femoral artery and obturator artery contribute minor supply, and the main femoral artery does not directly supply the head. Interruption of the retinacular vessels often causes avascular necrosis.
The head of the humerus is covered by which type of cartilage?
No cartilage; it is a bony surface
Elastic cartilage
Fibrocartilage
Articular (hyaline) cartilage
Articular (hyaline) cartilage coats the head of the humerus to reduce friction and absorb shock within the glenohumeral joint. Fibrocartilage is found in intervertebral discs and menisci, and elastic cartilage occurs in the ear and epiglottis. Without articular cartilage, joint movement would be painful and damaging.
In osteoarthritis of the hip, degeneration of cartilage at the head of the femur and acetabulum is indicated radiographically by:
Subchondral cyst formation
Presence of osteophytes
Increase in subchondral bone density
Reduction in joint space height
One of the hallmark radiographic signs of osteoarthritis is joint space narrowing due to cartilage loss at the head of the femur and acetabulum. Increased subchondral bone density, osteophyte formation, and subchondral cysts can also occur but are not as direct an indicator of cartilage degeneration.
A fracture at the anatomical neck of the femur most directly jeopardizes the blood supply from the retinacular arteries that run along the neck just below the head.
True
False
The retinacular arteries, which are branches of the medial circumflex femoral artery, ascend along the femoral neck to supply the femoral head. Fractures at the anatomical neck can sever these vessels, leading to avascular necrosis of the head. Such risk is less in fractures distal to the neck.
The head of the ulna articulates with which structure during pronation?
Proximal radioulnar joint
Radiocarpal joint
Humeroulnar joint
Distal radioulnar joint
During pronation and supination, the head of the ulna rotates within the ulnar notch of the distal radius at the distal radioulnar joint. The proximal radioulnar joint involves the head of the radius near the elbow. The radiocarpal joint is the wrist joint, and the humeroulnar joint is at the elbow.
The head of a typical rib articulates with how many vertebral bodies?
Two
Three
Four
One
The head of a typical rib features two facets: one articulates with the superior costal facet of its own numbered vertebra, and the other with the inferior costal facet of the vertebra above, totaling two vertebral bodies. First, eleventh, and twelfth ribs are exceptions, often articulating with a single vertebra.
In total hip arthroplasty, the prosthetic head is commonly made of which material to best mimic the natural articulation of bone?
Polyethylene
Steel
Glass
Ceramic
Ceramic heads are frequently used in hip prostheses because they offer a smooth surface with low friction and excellent wear resistance, closely resembling natural articular cartilage. Polyethylene is more commonly used for the acetabular liner, and stainless steel is less biocompatible and wears faster. Glass is not used due to its brittleness and poor mechanical properties.
The secondary ossification center for the head of the humerus typically appears at approximately what age in children?
1 year
2 years
5 years
Puberty
The secondary ossification center for the humeral head typically emerges around age 2 years, contributing to the growth of the proximal humerus. The primary ossification center appears in the shaft before birth, and other epiphyses appear later during childhood and puberty. Timing can vary slightly between individuals.
Approximately how many retinacular arteries run along the femoral neck to supply the head of the femur?
Three to four
One to two
Five to six
Seven to eight
Typically, there are three to four retinacular arteries, branches of the medial circumflex femoral artery, that ascend along the femoral neck to supply the femoral head. These vessels are crucial for bone viability and are vulnerable in neck fractures. Fewer or more vessels are atypical and less clinically common.

Cheat Sheet

  1. Definition of a Condyle -

    The condyle is a rounded process that usually articulates with another bone, forming a smooth joint surface essential for hinge and gliding motions (Gray's Anatomy). It's a key term in bone classification terms and anatomy bone articulations. Recognizing this process is crucial for acing any skeletal system quiz.

  2. Condyle vs. Epicondyle -

    While a condyle is a smooth, rounded articulation point, an epicondyle sits just above the condyle as a projection for ligament and tendon attachment (University of Michigan Anatomical Studies). Remember: "epi-" means "upon," so epicondyles are the bony bumps upon the condyles. This distinction often appears in bone structure questions.

  3. Condyloid (Ellipsoidal) Joints -

    Condyloid joints feature an oval condyle fitting into an elliptical cavity, allowing flexion, extension, abduction, adduction, and circumduction (Journal of Orthopaedic Research). The wrist joint (radiocarpal joint) is a classic example, illustrating complex anatomy bone articulations. Understanding this helps you tackle synovial joint classification items in quizzes.

  4. Real-Life Examples -

    The mandibular condyle articulates with the temporal bone to form the temporomandibular joint, enabling chewing and speaking (National Institutes of Health). In the knee, femoral condyles rest on tibial plateaus to support weight-bearing and flexion. Spotting these in radiographs or models boosts your confidence in skeletal system quiz settings.

  5. Mnemonic for Bone Projections -

    Use "CREST" to recall major bone classification terms: Condyle, Ramus, Epicondyle, Spine, Tubercle. Saying "Cool Rabbits Eat Spinach Tastily" ties each letter to its projection. This little trick powers through bone structure questions with ease.
