Q

Suprascapular nerve lesion motor, sensory, function

A

M: supraspinatus, infraspinatus
S: shoulder joint
F: reduced ability to “seat” humeral head (head moves forward during all shoulder
motion)
* reduced range of shoulder motion, particularly abduction and external rotation
(inability to use all of glenoid surface)

c6 dermotome

A

upper back and shoulders to lateral deltolid arm forarm to thumb

17
Q

c7 dermotome

A

middle deltoid arm forarm and hand posteriorly ONLY then digits 2,3 anteriorly and posteriorly

18
Q

c8 dermotome

A

at superior boarder of scapula to medial side of arm forearm and M 2 digits

19
Q

t1 dermotome

A

anterior and posterior around middle pec major, armpit/ anteriomedial surface of arm & forearm

20
Q

right vs left aortic branch

A

right- Brachiocephalic trunk
left- Direct branches from aorta

21
Q

Upper Limb Arteries

A

Identify
* Axillary
* Brachial
* Profunda brachii
* Radial
* Ulnar
* Superficial palmar arch
* Deep palmar arch

22
Q

Deep veins

A
  • run with arteries but in opposite direction
  • same name as arteries
  • e.g. axillary vein with axillary artery
  • contain valves
  • drain what the artery supplies
  • vena commitantes
23
Q

Superficial veins

A
  • in the superficial tissue
  • valves (not as many as deep veins)
  • anastomose (communicate) freely with the deep veins
  • best identified in the surface anatomy
  • Significance of having two sets of veins:
  • two ways to return blood to the heart, some in-built redundancy* temperature control
24
Q

deep veins are

A

radial, axially, ulna, brachial

25
Q

Superficial Veins are

A
  • Dorsal venous arch
  • Posterior surface of hand* Basilic vein
  • Ulnar side of dorsal venous arch, medial forearm & medial arm
  • Cephalic vein
  • Radial side of dorsal venous arch, lateral forearm & lateral arm
  • Median cubital vein
26
Q
  • Deep lymph vessels
A
  • Follow paired arteries/veins
27
Q
  • Superficial lymph vessels
A
  • Follow superficial veins
