Answer 5

C3/C4 spinal nerves

dorsal scapular nerve

Question 6

rhmoboid major and minor innervation

Answer 6

dorsal scapular nerve

Question 7

trapezius action and blood supply

Answer 7

elevates, depresses and retracts scapula
- rotates glenoid fossa superiorly
(transverse cervical artery)

Question 8

sheath of ligamentous tissue running down spinal column

Answer 8

nuchal ligament

Question 9

latissimus dorsi actions and blood supply

Answer 9

• extends, adducts and medially rotates humerus
• raises torso towards arms during climbing
  (thoracodorsal artery)

Question 10

actions of rhomboid major & minor and blood supply

Answer 10

BOTH retract, elevate and rotate scapula downward
and fix it to thoracic wall
(dorsal scapular artery)

Question 11

actiosn and blood supply of levator scapulae

Answer 11

PRIMARY function: elevate scapula
tilts glenoid fossa inferiorly by rotating scapula (downward roation)
blood supply (dorsal scapular artery)
