Deltoids muscle origin
Deltoid tuberosity of humerus (medial compartment o thighs, and sometimes considered part of the gluteal region)
Apex of coracoid process
Lateral margin of acromion
Greater tubercle of humerus
Supraglenoid tubercle of scapula
Triceps brachialis has
Short head – attached to infraglenoid tubercle of scapula (wrong because it has medial, lateral and long head)
Posterior head – attached to posterior surface of humerus (wrong because it has medial, lateral and long head)
Medial head – attached to medial lip of infratubercle sulcus (medically on humerus, caudal of tuberosity of teres major, crest of lesser tubercle)
Lateral head – attached to posterior surface of humerus
Three insertions on distal humerus
Brachialis muscle
Has two heads – long and short
Its origin is on the apex of coracoid process (distal half of anterior surface of humerus)
Its insertion is on radial tuberosity (coronoid process of the ulna; tuberosity of ulna)
Has the bicipital aponeurosis
Is innervated by the musculocutaneous nerve (and radial nerve)
The triangular interval is formed by
Inferior margin of teres major
Superior margin of teres major
Inferior margin of teres minor
Surgical neck of humerus

Is limited by flexor carpi radialis
Which from the muscles belongs to the intermediate layer of anterior compartment of forearm
Palmaris longus
Pronator teres
Flexor digitorum superficialis
Flexor digitorum profundus
Flexor carpi radialis
Tendons of which muscles are attached to the palmar aponeurosis
Flexor digitorum superficialis
Flexor digitorum profundus
Flexor pollicis longus
Palmaris longus
None
Which muscle is a part of the posterior wall of axilla
Teres major
Teres minor
Latissimus dorsi
Long head of biceps brachii
All
Which muscle is not attached on the lateral epicondyle of the humerus?
Extensor digitorum
Extensor digiti minimi
Anconeus
Extensor carpi radialis longus
Extensor carpi radialis brevis
The supinator muscle
Belongs to the deep layer of the anterior compartment of the arm
Is innervated by the ulnar nerve (no, the posterior interosseous nerve)
Is innervated by median nerve (no, the posterior interosseous nerve)
Has two heads (radial and ulnar)
Has two heads (ulnar and humeral)
In the fourth compartment of extensor retinaculum can be found tendons of:
Adductor pollicis longus and extensor pollicis brevis
Extensor pollicis longus and extensor carpi radialis longus and brevis
Extensor digitorum and extensor indicis
Extensor carpi ulnaris
Extensor digiti minimi
Which from below is not a branch of thoraco-acromial artery
Pectoral branch
Superior thoracic branch
Deltoid branch
Acromial branch
Clavicular branch
In the cubital fossa can be found
Profunda brachii artery
Anterior and posterior circumflex humeral artery
Superior ulnar collateral artery
Radial collateral artery
None
The radial artery
Can be palpated laterally to flexor carpi ulnaris is proximal forearm
Passing through carpal tunnel
Can be palpated between brachioradialis and flexor carpi radialis in distal forearm
Its branch is the common interosseus artery
Passes through the forearm between flexor carpi ulnaris and flexor digitorum profundus
The axillary artery
Is separated into two parts by the teres minor
Is separated into three parts by pectoralis major
Is divided directly into ulnar and radial arteries
Is separated into three parts by the pectoralis minor
Ends at the inferior border of teres minor
Which vein is not the superficial vein of upper limb
Cephalic vein
Basilic vein
Median cubital vein
Median antebrachia vein
All are superficial
Choose wrong statement about suprascapular nerve
Contains spinal nerve C5 and C6
It originates from the superior trunk of brachial plexus
Passes through suprascapular notch
Passes through spinoglenoid notch
Innervates subscapularis muscle ?
Which nerve does not originate from the lateral cord of brachial plexus
Axillary nerve
Musculocutaneous nerve
Median nerve
Lateral pectoral nerve
All do
The axillary nerve
Passes through the triangular interval accompanied by the profunda brachii artery
Passes through triangular space accompanied by the circumflex artery
Passes through quadrangular space accompanied by circumflex humeral artery
Passes through greater scapular notch accompanied by the suprascapular artery
Passes through the clavipectoral triangle accompanied by the pectoral branch of the turaco-acromial artery
“Extensor hoods” are formed by the tendons of
Extensor digitorum & extensor pollicis longus
Extensor carpi radialis longus and brevis
Extensor carpi ulnaris and extensor digitorum
Extensor carpi ulnaris
None
