Shoulder Girdle

Question 0

Distal attachment Serratus Anterior

Answer 0

Costal surface of medial border of the scapula, between the superior and inferior angles.
The upper digitation passes to the superior angle, the lower four converge to attach to the inferior angle and the attachment of the intervening fibres (2nd, 3rd, 4th digitations) is spread along the border between these two points

Question 1

Proximal attachment Serratus Anterior

Answer 1

Fleshy digitations just anterior to mid-axillary line, attaching to the outer surfaces of the upper eight or nine ribs and intervening intercostal fascia
The first digitation attaches to ribs one and two; the remaining digitations arise from a single rib with the lower four slips interdigitating with the costal attachment of External Abdominal Oblique

Question 2

Nerve supply Serratus Anterior

Answer 2

Long Thoracic Nerve C5,C6,C7

Question 3

Proximal attachment Trapezius

Answer 3

Medial third of superior nuchal line and external occipital protuberance of the occipital bone of the skull
Ligamentum nuchae
Spinous processes of C7-T12 inclusive and intervening supraspinous ligaments

Question 4

Distal attachment Trapezius

Answer 4

Upper fibres- posterior border of lateral one third of clavicle
Middle fibres- medial border of acromion and upper border of crest of spine of scapula
Lower fibres- tubercle on inferior edge at the medial end of the spine of the scapula

Question 5

Nerve supply Trapezius

Answer 5

Motor supply- spinal part of Accessory Nerve (XI cranial)

Sensory supply- ventral rami of C3 and C4 from cervical plexus

Question 6

Proximal attachment Levator Scapulae

Answer 6

Tendinous slips to transverse processes of the upper three or four cervical vertebrae C1-C4

Question 7

Distal attachment Levator Scapulae

Answer 7

Medial border of scapula between superior angle and medial end of the spine of the scapula

Question 8

Nerve supply of Levator Scapulae

Answer 8

Dorsal Scapular Nerve C5 and ventral rami of C3 and C4

Question 9

Proximal attachment Rhomboid Minor

Answer 9

Spinous processes of C7 and T1 vertebrae and supraspinous ligament between them.
Inferior part ligamentum nuchae

Question 10

Distal attachment Rhomboid Minor

Answer 10

The base (medial border) of the smooth triangular area at the medial end of the spine of the scapula

Question 11

Proximal attachment Rhomboid Major

Answer 11

Tendinous slips from spinous processes of T2-T5 and the intervening supraspinous ligaments

Question 12

Distal attachment Rhomboid Major

Answer 12

Medial border of scapula between base of the spine and the inferior angle

Question 13

Nerve supply Rhomboids

Answer 13

Dorsal Scapular Nerve C5

Question 14

Proximal attachment Pectoralis Minor

Answer 14

Outer surfaces of the 3rd, 4th and 5th ribs close to their costal cartilages and intervening costal fascia
May be additional attachments to either the second or sixth rib or occasionally both

Question 15

Distal attachment Pectoralis Minor

Answer 15

Superior surface and medial border of the coracoid process of the scapula

Question 16

Nerve supply Pectoralis Minor

Answer 16

Medial and Lateral Pectoral Nerves C6,C7,C8

Question 17

Proximal attachment Latissimus Dorsi

Answer 17

All of lumbar and sacral vertebrae and to intervening supraspinous and interspinous ligaments
Posterior part of outer lip of iliac crest
Outer surfaces of lower 3 to 4 ribs
Dorsal aspect of inferior angle of scapula

Question 18

Distal attachment Latissimus Dorsi

Answer 18

Floor of intertubercular sulcus (bicipital groove) on the humerus between Pectoralis Major (laterally) and Teres Major (medially)

Question 19
