0

What is a collection of cell bodies in the CNS called?

Nucleus

1

Where are the ganglia located in a) the sympathetic and b) parasympathetic?

a) close to the CNS
b) close to or in the target

2

What are the ganglionic neurotransmitters in both parasympathetic and sympathetic?

Acetylcholine and nicotinic

3

What NT is used in the somatic NS for a) efferent and b) afferent?

a) acetylcholine and b) glutamate

4

What is the postganglionic receptor and NT for parasympathetic and sympathetic?

Parasympathetic- acetylcholine and muscarinic
Sympathetic- noradrenaline a and b

5

What is a bundle of axons in the PNS called?

Nerve

6

Where is the neurone body located in a) efferent and b) afferent neurones of the somatic NS?

a) CNS and b) PNS

7

What type of muscle does the autonomic NS control?

Smooth and cardiac muscle

8

What is a ganglion in terms of neurones?

A collection of cell bodies in the PNS

9

Do parasympathetic or sympathetic have long preganglionic fibres?

Parasympathetic

10

Which parasympathetic or sympathetic has branched postganglionic fibres?

Sympathetic

11

What is a tract in terms of neurones?

A bundle of axons in the CNS

12

What type of muscle does the somatic NS control?

Skeletal muscle

13

What are supporting glia called?

Astrocytes

14

What do microglia do?

Immune cells of the CNS, clean up the toxic waste in the CNS after death. 'Scavengers'

15

What do astrocytes do?

Provide nutrients to the nervous tissue and the repairing/scarring process in the brain

16

Give the types of nerve cell?

Neurones

17

What does the CNS include?

The brain and the spinal chord

18

What does the PNS include?

The periphery neurones

19

What branches of the autonomic NS are there?

Sympathetic and parasympathetic

20

What neurones go from the receptor to the CNS?

Afferent

21

What two branches of the motor PNS are there?

Autonomic and somatic

22

What neurones go from the CNS to the effector?

Efferent

23

What two types of neurones are involved in the somatic NS?

Sensory afferent and motor efferent

24

What do the dendrites and axons of neurones do?

Dendrites receive information and axons pass on information

25

Can multiple synapses contact one dendrite?

Yes

26

Give the three types of supporting cells?

Neuroglia, glial cells and glia

27

What are the two types of cells in the NS?

Nerve cells and supporting glia

28

Is sympathetic or parasympathetic used for housekeeping?

Parasympathetic, sympathetic is for flight, fright and fight response

29

What functions do the parasympathetic and sympathetic NS have?

Anatomical and functional devision, generally antagonistic

30

What is the somatic nervous system often called?

The voluntary nervous system

31

Which axons in the somatic nervous system are myelinated?

Efferent, afferent are not.
