Answer 2

Levator scapulae

Rhomboid minor and major

Question 3

Proximal and distal attachments of the trapezius

Answer 3

P: Nuchal line, external occipital protuberance, Nuchal ligament, spinous process if thoracic vertebrae (c7-c12)
D: lateral 3rd if clavicle, acromion and spine of scapula

Question 4

Innervation of trapezius

Answer 4

Spinal accessory nerve

Question 5

Action of trapezius

Answer 5

Descending part elevates;
Ascending part depresses;
Middle part retracts scapula
Descending and ascending parts act together to upwardly rotate scapula

Answer 6

P: inferior thoracic spinous processes, thoraco lumbar fascia, iliac crest & Inferior ribs
D: intertubular sulcus of humerus

Question 7

Innervation of latissimus Dorsi

Answer 7

Thoracodorsal nerve

Question 8

Action of latissimus Dorsi

Answer 8

Extends, adducts and medically rotates humerus

Also raises body to trunk when climbing

Question 9

Prox and distal attachments of levator scapulae

Answer 9

P: transverse processes of C1-C4 vertebrae
D: superior and to medial border of scapula spine

Question 10

Innervation of levator scapulae

Answer 10

Dorsal scapular nerve and cervical nerves

Question 11

Action of levator scapulae

Answer 11

Elevates scapula and rotates it’s glenoid cavity inferiorly by rotating scapula -downward rotation of scapula

Question 12

Prox and distal attachments of rhomboid minor and major

Answer 12

P: Minor- Nuchal ligament and spinous processes of C7 and T1
Major- spinous processes of T2-T5
D: Medial border of scapula

Question 13

Innervation of rhomboids

Answer 13

Dorsal scapular nerve

Question 14

Answer 14

Retract scapula

Fixes scapula to the thoracic wall
