1

Nerves that take information to the brain are known as

Afferent nerves

2

Nerve that take informatoin from the brain are known as

Efferent nerves

3

What is the nervous system composed of

The central nervous system and the periperal nervous system

4

What is the function of the nervous system

To control and coordinate the function of organ systems

5

What are the three membranous layers that cover the brain

The pia mater, the arichnoid mater and the dura mater

6

What are the three membranous lyaers that cover the brain known as

The meninges

7

What surrounds and protects the CNs

The meninges and the ceribrospinal fluid

8

What is the innermost meningal covering

The pia mater

9

What is the middle meningal covering

The arichnoid mater

10

What is the outermst meningal covering

The dura mater

11

What is the dura mater intimately related to

The internal aspect o the bone surrounding the neurocranium

12

What separates the dura mater from the surrounding bone in the vertebral column

A fat filled epidural space

13

What are the main arteries that supply the brain

The common carotid, external carotid, internal carotid and vertebral arteries

14

What is formed when the vertebral arteries join

The basilar artery

15

What arteries come from the bifurcation of the basilar artery

The anterior and middle cerebral arteries

16

What arises from the external carotid artery

the middle meningeal artery

17

Where does the middle meningeal artery enter the skull

21

What are the brain and spinal cord composed of

Grey matter and white matter

22

Where are the nerve cell bodies found

Within the grey matter

23

Where are the interconnecting fibre tract systems found

Within the white matter

24

What is held within the grey matter

Neurons, cell processes, synapses and support cells

25

What is held within the white matter

Axons and their support cells

26

What is the appearance of the grey matter in the spinal cord

An h-shaped area

27

What is the outer layer of matter in the spinal cord

White matter

28

What are the two principle cells of the nervous system

Neurons and glial cells

29

Functions of neurons

Recieve information, integrate he information and then transmit electrical impulses to another neuron/effector cell

30

What are the four tyes of glial cells

Astrocytes, oligodendrocytes, microglia and ependymal cells
