Q

Typical components within a spinal nerve?

A

Somatic sensory, visceral sensory, autonomic motor, somatic motor

20
Q

Splanchnic Nerves

A

innervate many visceral organ systems throughout body

21
Q

Ansa Cervicalis

A

part of the cervical plexus it innervates some strap muscles

22
Q

Phrenic nerve

A

part of the cervical plexus it provides somatic motor innervation to the diaphragm (C3,4,5) keeps diagphragm alive

23
Q

complex collection of nerves from the spinal cord travelling through the neck and axilla to innervate muscles of the skin in the upper limb and shoulder

A

Brachial Plexus

24
Q

What plexus is formed from the anterior rami of the C5 - T1 Spinal segments

A

Brachial Plexus

25
Q

How is the brachial plexus divided proximal to distal

A

Roots => Trunks => Divisions => Cords => Branches

26
Q

What nerve of the brachial plexus innervates the Anterior Arm Compartment, and skin over the lateral forearm

A

Musculocutaneous

27
Q

What nerve of the brachial plexus innervates most of the anterior compartment of the forearm, and some muscles (thumb muscles) of the hand, and some skin of the hand

A

Median

28
Q

What nerve of the brachial plexus innervates a little of the anterior forearm, and most of the muscles of the had, and some skin of the hand

A

Ulnar

29
Q

What nerve of the brachial plexus innervates the posterior compartment of the arom and forearm and skin over the posterior upper extremities.

A

Radial

30
Q

What nerve of the brachial plexus controls flexion of the elbow?

A

Musculocutaneous

31
Q

What nerve of the brachial plexus controls flexing of the wrist and some fingers/thumb?

A

Median nerve

32
Q

What nerve of the brachial plexus controls movement of the hand?

A

Ulnar

33
Q

What nerve of the brachial plexus controls extension of the elbow and wrist?

A

Radial

34
Q

Upper Brachial Plexus injury?

A

Neck injury, damages Musculocutaneous Nerve, patient cant flex the elbow

35
Q

Lower Brachial Plexus Injury?

A

Armpit injury, damages ulnar nerve, weak hand motions

36
Q

Intercostal Nerves

A

Anterior rami of thoracic spinal nerves, DO NOT FORM PLEXUS, Somatic motor innervation to intercostal muscles, lower continue to innervate ab wall muscles, Cutaneous dermatomes of trunk

37
Q

Lumbosacral Plexus

A

Lower limb and Gluteal System, conects the two plexuses

38
Q

What are the nerves of the Lumbosacral Plexus

A 
Femoral nerve -
Obturator Nerve, 
Sciatic Nerve
   -Tibial Nerve
   -Common Fibular Nerve
Pudendal Nerve
39
Q

Which nerve of the Lumboscarcal Plexus innervates the anterior thigh and what is its function?

A

Femoral, extension of knee

40
Q

Which nerve of the Lumboscarcal Plexus innervates the medial thigh, and what is its function?

A

Obturator, adduct legs

41
Q

Which nerve of the Lumboscarcal Plexus innervates the posterior thigh, leg, foot and what is its function?

A

Sciatic nerve, has a tibial and fibular branch

42
Q

What branch of the sciatic nerve innervates the posterior legan and most of foot?

A

Tibial Nerve

43
Q

What branch of the sicatic nerve innervates the anterior and lateral leg?

A

Common Fibular Nerve

44
Q

What is the “shameful nerve” and what does it innervate?

A

pudendal, it inervates the perineum and external genitalia

function: somatic sensory to erectile tissue and muscles of continence

45
Q

Pain perceived at a location that is not injury site?

A

perceived pain

46
Q

Why does perceived pain happen?

A

Incoming signals from visceral and somatic afferents coming to the same spinal segment “confuse” the brain into thinking that the visceral pain is coming from elsewhere.

47
Q

Appendix and Heart perceived pain sites?

A

Pain on belly button, pain on Upper limb
