Shoulder

Question 0

Distal attachment Deltoid

Answer 0

Deltoid tuberosity on lateral aspect of shaft of humerus

Question 1

Proximal attachment Deltoid

Answer 1

Anterior fibres- anterior border and superior surface of lateral third of clavicle
Middle fibres- four tendinous slips which are attached to the superior surface and lateral margin of the acromion process
Posterior fibres- inferior lip of crest of spine of scapula as far back as the triangular area at its medial end

Question 2

Nerve Supply Deltoid

Answer 2

Axillary Nerve C5,C6

Question 3

Proximal attachment Pectoralis Major

Answer 3

Clavicular attachment- medial half of the anterior surface of the clavicle
Sternocostal attachment- half of the anterior surface of the upper six costal cartilages and the anterior part of the sixth rib and also from a fibrous aponeurosis of the External Abdominal Oblique muscle
Half of anterior surface of manubrium and body of sternum

Question 4

Distal attachment Pectoralis Major

Answer 4

Lateral lip of intertubercular sulcus of humerus

Question 5

Nerve supply Pectoralis Major

Answer 5

Medial (C8, T1) and Lateral (C5, C6, C7) Pectoral Nerves.
Clavicular part by roots C5, C6
Sternocostal part by roots C7, C8, T1

Question 6

Proximal attachment Biceps Brachii

Answer 6

Short head- apex of coracoid process of scapula, lateral to Coracobrachialis
Long head- supraglenoid tubercle of the scapula and the adjoining part of the glenoid labrum within the capsule of the shoulder joint

Question 7

Distal attachment Biceps Brachii

Answer 7

Posterior aspect of radial tuberosity
From its medial border it gives off a broad aponeurosis- the bicipital aponeurosis, which attaches to the deep fascia of the forearm and the posterior border of the proximal ulna

Question 8

Nerve supply Biceps Brachii

Answer 8

Musculocutaneous Nerve C5,C6

Question 9

Proximal attachment Coracobrachialis

Answer 9

Apex of coracoid process of scapula

Question 10

Distal attachment Coracobrachialis

Answer 10

Medial aspect of shaft of humerus at about its midpoint, between Brachialis and Biceps Brachii

Question 11

Nerve supply Coracobrachialis

Answer 11

Musculocutaneous Nerve C5, C6, C7

Question 12

Proximal attachment Brachialis

Answer 12

Distal two thirds of the anterior aspect of the shaft of the humerus, extending outwards onto the medial and lateral intermuscular septum

Question 13

Distal attachment Brachialis

Answer 13

Brachialis impression on the inferior aspect of the coronoid process and the tuberosity of the ulna. Some deep fibres blend into the capsule of the elbow joint

Question 14

Nerve supply Brachialis

Answer 14

Musculocutaneous Nerve C5, C6

A branch from the Radial Nerve C6, C7
