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

The orbital fossa

Is a quadrangular depression

Contains tendon of biceps brachii

Is limited by pronator quadratus

Contains radial nerve

Is limited by flexor carpi radialis

Which from the muscles belongs to the intermediate layer of anterior compartment of forearm

Tendons of which muscles are attached to the palmar aponeurosis

Which muscle is not attached on the lateral epicondyle of the humerus?

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

In the cubital fossa can be found

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

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

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
