Q

Muscles of tounge

A

C12- Hypoglossal

21
Q

test for visual acuity

A

C2- Optic

by having a person identify the number of fingers held up in each visual field

22
Q

test for smell

A

C1- Olfactory

Have person identify familiar odors applied to each nostril (vanilla, peppermint, coffee)

23
Q

Cranial nerves associated with eye movement testing

A

C3-Oculomotor
C4-Trochlear
C6- Abducens
(H-pattern movement)

24
Q

What movements will be affected if someone has damaged CN 111?

A

can impair ocular motility, pupillary function, or both

25
Q

What movements will be affected if someone has damaged CN 4

A

it may not be able to do its job. Controlling the movement of the superior oblique muscle

26
Q

what movements will be affected if someone has damaged CN 6

A

The abduction of the eyeball, Eye muscle lateral rectus

27
Q

Facial sensation test

A

C5- Trigeminal

“chewing muscle strength”

28
Q

“Facial expression” muscle strength

A

C7- Facial

29
Q

Traps, SCM movement tested

A

C11- Accessory

30
Q

Tounge movement tested

A

C12- Hypoglossal

31
Q

How many Spinal nerves are there?

A 
31 total
8 cervical
12 thoracic
5 lumbar
5 sacral
1 coccygeal
32
Q

How does each nerve exit?

A

Vetebral canal via the intervetebral foramen

33
Q

Nerve plexus

A

Rather than directly supplying the body structures upon exiting the spinal cord (mainly the limbs): the anterior rami form cervical plexus by joining the anterior rami and the adjacent nerves
except T2-T12

34
Q

Plexuses allow for a merging of the axons that were contained within each of the spinal nerves

A

Nerve plexuses

35
Q

Nerves between C1-C4 (AND A PORTION OF C5) is called?

A

Cervical plexus

36
Q

What is the only nerve we should remember in the cervical plexus and what does it do?

A

The phrenic nerve (C3,C4 AND C5 keep them alive) which innervates the diaphragm muscle

37
Q

Brachial Plexus

A

nerves arise between C5-T1 ->supplying by innervating-> the entire arm and some neck and shoulder muscles

38
Q

Brachial plexus process

A

From proximal to distal, The nerve roots (C5-T1) merge and divide together to eventually give rise to the peripheral nerve branches that innervate various structures in the upper and lower limbs. (Roots->Trunks->divisions->cords>branches)

  1. (C5-T1) ROOTS merge into 3 TRUNKS (C5&6-> UPPER, C7->MIDDLE, C8,T1-> LOWER)
  2. Trunks split into Divisions (Anterior & Posterior)
  3. The posterior divisions of all trunks form the posterior cord, the anterior divisions of all trunks form the Lateral and Medial cords
  4. The cords then give rise to various peripheral nerve branches
39
Q

Lumbar plexus

A

L1-L4

40
Q

Sacral Plexus

A

nerves arising from L4-L5 and S1-S4

Some of the nerves of the sacral plexus contain fibers from the lumbar plexus, this is known as the lumbosacral plexus

41
Q

How do peripheral nerve branches work?

A
  1. Nerve exits from the plexus as “nerve branches”- each containing sensory axons, motor axons and both
  2. Each nerve has a “spinal component/nerve root” which indicates which spinal nerves contributed to its formation
42
Q

Each nerve will provide either both:

A

Sensory axons: skin, muscle, joint and connective tissue components
Motor axons: muscle
both

43
Q

Cutaneous innervation is…

A

Refers to the area of skin innervated by a specific peripheral nerve branch

44
Q

Interdome refers…

A

an area of skin innervated by the cutaneous branch of a single spinal nerve

45
Q

Motor Branches of the Brachial plexus

A 
Dorsal Scapular= C5 
Long thoracic=C5-C7
Suprascapular=C5-C6
Thoracodorsal=C6-C8
Axillary=C5-C6
Musculocutaneous=C5-C7
Radial= C5-C8, T1
Ulnar= C8, T1
Median=C5-T1
46
Q

Motor branches of the lumbar plexus

A

Femoral->L2-L4 ->

Obturator->L2-L4->

47
Q

Motor Branches of the sacral plexus

A 
Sciatic-> L4-S3
Tibial (medial and lateral plantar)-> L4-S3
Common fibular (peroneal)-> L4-S2
Superficial->L4-S2
Deep->L4-S2
48
Q

Cutaneous innervation of the limbs

A

Supraclavicular-> neck and superior shoulder
Axillary-> Lateral shoulder
Musculocutaneous-> Lateral elbow and forearm
Radial-> Posterior arm/forearm; Lateral 2/3 of dorsal hand and 3.5 digits up to DIPS
Median-> Lateral 2/3 Volar hand and 3.5 fingers
Ulnar->Medial 1/3 hand including the entirety of D5 and medial 1/2 of D4
Lateral femoral cutaneous nerve of thigh-> Lateral Thigh
obturator-> medial thigh
Saphenous-> Anteromedial, medial and posteromedial of leg and foot
Sural-> Posterolateral leg and foot
Common Fibular (Peroneal)-> Proximal anterolateral leg
Superficial Fibular (Peroneal)-> Distal anterolateral leg and dorsum of foot
Tibial (Medial and Lateral Plantar)-> Plantar foot

49

  • Calvaria (skull cap)
  • Base of the skull
  • Anterior, middle, posterior cranial fossa
