Q

How can we identify which nerve we are targeting without using ultrasound?

a) By visual inspection
b) By palpation
c) By applying an electrode and current
d) By using a stethoscope

A

c) By applying an electrode and current

If it’s a mixed nerve it will recruit the motor nerves in the area we are trying to block [resulting in contraction of the muscles]; This gives us an idea of where we are when we are trying to block

13

81
Q

True or False

The Nuchal (Occipital) nerves are named based on their function and location.

A

True

The name is derived from the nuchal ligament that sits in back of neck; The nuchal nerves are names for what they are and what they do.

14

82
Q

Where is the lesser occipital nerve positioned relative to the greater occipital nerve?

a) Above
b) Below
c) At the same level

83
Q

From which cervical spinal nerve does the Greater Occipital Nerve originate?

a) C1
b) C2
c) C3
d) C4

A

b) Spinal Nerve C2

Probably larger or on top of any other occipital nerve; It sits farther up on top of the head and also lies over the back of the head (occipital bone)

b) C2
c) C3
d) C4

A

c) Spinal Nerve C3

14

85
Q

What is the primary function of the supraclavicular nerve?

a) Motor innervation to the shoulder muscles
b) Sensory innervation to the top of the shoulder
c) Autonomic innervation to the shoulder glands
d) Blood supply to the clavicle

A

b) Sensory innervation to the top of the shoulder

14

86
Q

Which of the following are true about the suboccipital nerve?

b) It has a dermatome
c) It is purely a motor nerve
d) It provides sensory innervation to the neck muscles
e) It has branches that are on the bottom of the muscles in the neck

A

a) It originates from spinal nerve C1

c) It is purely a motor nerve

THERE IS NO DERMATOME C1 because C1 is purely a motor pathway ; Has a bunch of branches that are on top of the muscles in the neck
