1

Define neurology

branch of medicine that deals with anatomy, physiology (function) and disorders of the nervous system

2

Name the three areas involved in the study of neurology

anatomy, physiology (function) and disorders

3

_____ are receptor branches.

dendrites

4

The ___ contains DNA.

cell body/soma

5

Ganglia are clusters of cell bodies found in the ___.

PNS

6

Nuclei are clusters of cell bodies in the __.

CNS

7

What transmits electrical impulses from cell bodies to terminal buttons and are covered in a myelin sheath?

axon

8

Tract is a bundle of __ in the __.

axons; CNS

9

Nerve is a bundle of __ in the __.

axons; PNS

10

What are gaps in myelinated called?

Nodes of Ranvier

11

The __ contains synaptic vesicles.

terminal button

12

How many main types of cells are there in the nervous system?

2 main types

13

Name the types of cells in the nervous system and their functions.

Glial cells support cell function. Neurons - communication

14

The nerve cell that carries impulses from a sensory receptor to the brain or spinal

Sensory neuron

15

The nerve cell that transmits impulses from the brain or spinal cord to a muscle or gland.

Motor neuron

16

The connections between sensory and motor neurons are called _.

interneurons

17

How is information transmitted in the nervous system (at the cellular level)?

Electrical energy moves down towards the muscles, turns into chemical energy between cells, then goes back into electrical energy. This happens at synaptic cleft.

18

Central nervous system (CNS) includes __ and __

Brain and spinal cord

19

Peripheral nervous system (PNS) includes __ and __ (cell bodies) __ of the CNS.

nerves; ganglia; outside

20

PNS includes __ nervous system and __ nervous system

Somatic and autonomic

21

Name the layers of the meninges of the brain from superior to inferior

Dura mater, arachnoid membrane, pia mater

22

What is the name of the space between the arachnoid membrane and the pia mater?

subarachnoid space

23

Subarachnoid space contains what (2 things)?

Blood vessels and cerebrospinal fluid (CSF)

24

True/False: Meninges are the inner coverings of the brain.

False; outer coverings.

25

T/F: Between the arachnoid and pia mater is the subarachnoid space which contains blood vessels and cerebrospinal fluid?

True

26

What are the (4) main components of the brain?

cerebrum, cerebellum, subcortical structures, brainstem

27

Name the ventricles in the brain.

2 lateral ventricles, third ventricle, fourth ventricle

28

What does the CSF do?

Cleans and protects the brain and spinal cord by circulating throughout the ventricles

29

5

30

Name the lobes of the brain.

Frontal, temporal, parietal, occipital, insula
