18
Q

Give an example of a muscle which the dorsal ramus can supply

A

Erector Spinae

19
Q

Given an example of a muscle which the ventral ramus can supply

A

Intercostal muscles
Abdominal wall

20
Q

What is cutaneous innervation?

A

An area of skin which is supplied by a specific cutaneous nerve

21
Q

What does a cutaneous nerve contain?

A

Nerve fibres from several spinal nerves

22
Q

How does a dermatome differ to a cutaneous nerve?

A

Dermatome is an area of skin supplied by one spinal nerve.
A cutaneous nerve can consist of fibres from many different spinal nerves.

23
Q

Give an example of one area where the cutaneous nerves and dermatomes are the same.

A

Thorax
Abdomen

24
Q

Where in the body do the cutaneous nerves and dermatomes differ?

A

Limbs

25
Q

Which type of innervation is more specific-dermatome or cutaneous nerve

A

Dermatome

26
Q

Where does the lateral antebrachial cutaneous nerve supply?

A

Lateral side of the forearm

27
Q

Which level does the spinal nerves of the lateral antebrachial cutaneous nerve arise from?

A

C5-6

28
Q

Where does the radial dorsal antebrachial cutaneous nerve supply?

A

Lateral side of the arm

29
Q

Which level does the spinal nerves of the radial dorsal antebrachial cutaneous nerve arise from?

A

C5-6

30
Q

Which joint occurs in the midline of the trunk at dermatome T2?

A

Sternomanubrial joint

31
Q

What surface feature is present at dermatome T4?

A

Nipples

32
Q

What surface feature is present at dermatome T10?

A

34
Q

What is the fatty white substance which surrounds the axon of some nerve cells?

A

Myelin

35
Q

Which cells secrete myelin?

A

Schwann cells

36
Q

What is the function of myelin?

A

Forms an electrically insulating layer

37
Q

What forms a layer around a myelin sheath for each nerve fibre?

A

Endoneurium

38
Q

What is the endoneurium composed of?

A

Thin layer of connective tissue

39
Q

What surrounds each fascicle of nerve fibres?

A

Perineurium

40
Q

In a nerve is big enough, what surrounds it?
