Study Outcomes

  1. Identify Highlighted Structures -

    Pinpoint the highlighted structure in each quiz prompt, from the capitulum of the humerus to specific ribs, reinforcing your ability to recognize bone landmarks.

  2. Determine Bone Association -

    Answer questions on the highlighted structure is part of which bone, enabling you to link each anatomical feature to its parent bone accurately.

  3. Analyze Articulation Points -

    Interpret scenarios asking the highlighted structure articulates with which structure and bone or which of the following, sharpening your understanding of joint relationships.

  4. Differentiate Bone Landmarks -

    Contrast similar bony projections and indentations, such as the capitulum versus other distal humeral landmarks, to improve your skeletal anatomy discrimination.

  5. Apply Skeletal Knowledge -

    Engage with interactive questions to apply what you've learned about anatomy and identify the highlighted structure ribs, pelvis components, and skull features in context.

Cheat Sheet

  1. Recognizing Capitulum Landmarks -

    Understanding which structure is highlighted capitulum helps you identify the lateral distal humerus on axial diagrams; remember that the capitulum articulates with the head of the radius. Gray's Anatomy describes the capitulum as a rounded eminence whose surface is smooth and articulates laterally. Try the mnemonic "C for Circle meets Radius" to cement this in your mind.

  2. Key Articulation Questions -

    In many quizzes you'll ask the highlighted structure articulates with which structure and bone; for example, the olecranon fossa articulates with the olecranon process of the ulna. According to Netter's Atlas, knowing these pairs boosts your recall of joint surfaces. Practice by labeling diagrams and reciting "Fossa meets process from the same bone pair" as you study.

  3. Mapping Ribs and Costal Grooves -

    When you identify the highlighted structure ribs, focus on the costal groove on the inferior border, which shields intercostal vessels and nerves. The American Thoracic Society notes the groove's role in protecting these structures during breathing. A handy mnemonic is "RIGht under RIB" to recall the costal groove position.

  4. Bone Ownership: Pelvic Landmarks -

    Questions like the highlighted structure is part of which bone often refer to the iliac crest, which belongs to the ilium portion of the pelvis. The University of Michigan's anatomical database confirms the iliac crest as the superior ridge of the ilium. Try saying "Ilium's top helmet is the crest" to memorize its location.

  5. Skull Condyle Connections -

    On skull quizzes the highlighted structure articulates with which of the following? The occipital condyles interface with C1 (atlas) to support nodding. Research from the American Association of Anatomists highlights this as a critical joint for head movement. Use the phrase "Atlas nods on Occiput legs" to solidify the link.
