1

What are the five types of nerve fibre?

Somatic sensory

Somatic motor

Visceral afferents / sensory

Sympathetic

Parasympathetic

2

What are the two types of sensory nerve?

Somatic sensory

Visceral afferent

3

What are the three types of motor nerve?

Somatic motor

Sympathetic

Parasympathetic

4

Which type of nerve receives sensation from the body wall?

Somatic sensory

5

Which type of nerve receives sensation from the internal organs?

Visceral afferent

6

What type of nerve innervates skeletal muscle?

Somatic motor

7

What types of nerves send motor impulses to the internal organs?

Sympathetic

Parasympathetic

8

Which nerves control peristalsis of the ureters and contraction of the bladder?

Sympathetic

Parasympathetic

motor to internal organs

9

Which nerves control the

a) internal urethral sphincter in males

b) external urethral sphincter and levator ani?

a) Sympathetic / parasympathetic (internal organs)

b) Somatic motor (as they're in the perineum)

10

Which nerves pick up sensation from the kidneys, ureters, bladder, testes and pelvic urethra?

Visceral afferents

The distal urethra, found in the perineum, has a somatic sensory innervation

11

Which nerves are found in the lumbar and sacral plexuses?

Somatic sensory

Somatic motor

supplying perineum and lower limbs

12

How many pairs of cranial nerves are there?

12

13

At which levels do sympathetic nerves leave the spinal cord?

T1 - L2

THORACOLUMBAR OUTFLOW

14

Where do sympathetic nerves leave the spinal cord?

Anterior horns

15

Where do sympathetic nerves synapse after leaving the spinal cord from T1 - L2?

Sympathetic chain

16

Where can post-synaptic sympathetic nerves travel?

Up and down the full length of the spinal cord

17

Every spinal level has a ___ for post-synaptic sympathetic nerves.

What is the exception?

ganglion

Head and neck - superior, middle and inferior cervical ganglia

18

How do post-synaptic sympathetic nerves travel to organs in the

a) head and neck

b) thorax

c) abdomen?

a) Periarterial plexuses

b) Cardiopulmonary splanchnic nerves

c) Abdominopelvic splanchnic nerves

(c) NOT the same as parasympathetic pelvic splanchnic nerves

19

What are the two types of sympathetic splanchnic nerve?

a) Cardiopulmonary splanchnic nerve

b) Abdominopelvic splanchnic nerve

20

How do post-synaptic sympathetic nerves reach the organs of the head and neck?

Hitch a ride on arteries

Periarterial plexuses

21

Where does the spinal cord end?

L1

Conus medullaris, then cauda equina to S1

22

The sympathetic chains run along how much of the vertebral column?

The whole thing

23

How do sympathetic nerve fibres get to the kidneys, ureters and bladder?

Abdominopelvic splanchnic nerves

synapsing at abdominal sympathetic ganglia on the way

then passing along periarterial plexuses

24

Which cranial nerves do parasympathetic nerves come from?

Where else do they come from?

CN III, VII, IX and X

oculomotor, facial, glossopharyngeal and vagus nerves

Sacral spinal nerves

25

Keeping in mind where parasympathetic nerves come from, what is their outflow called?

Craniosacral outflow

26

How do parasympathetic nerves reach the pelvic organs?

Pelvic splanchnic nerves

27

What is the difference between pelvic and abdominopelvic splanchnic nerves?

Pelvic - parasympathetic, come from sacral spinal nerves

Abdominopelvic - sympathetic, come from all over the place

28

Which parasympathetic nerves supplies the

a) kidneys and ureters

b) bladder?

a) Vagus nerve CN X

b) S2 - 4

29

What pelvic organs are supplied by the

a) sacral spinal nerves

b) vagus nerve?

a) Bladder

b) Kidneys and ureters

30

Which spinal nerves supply the pudendal nerve?

S2, 3, 4
