Module 4/chapter 23/nervous System/terms Associated With The Nervous System

Front 1

Cerebellum

Back 1

Located at the back of the head below the cerebrum. Maintains balance and coordination and is responsible for voluntary movement.

Front 2

Cranial nerves

Back 2

There are 12 pairs of cranial nerves orginating in the brainstem. They control the activities of the face and head.

Front 3

Name the three layers of Meninges.

Back 3

1)dura mater (outside)
2)arachnoid membrane (second or middle layer)
3)pia mater (closest to the brain and spinal cord containing blood vessels)

Front 4

Cerebrum

Back 4

Largest part of the brain responsible for intelligence, learning, judgment, memory, emotion association and discrimination.

Front 5

CSF

Back 5

Cerebrospinal fluid -- clear, watery fluid that cushions the brain and spinal cord.

Front 6

Myelin sheath

Back 6

Fatty tissue that surrounds and protects the axon of a nerve cell of the brain and spinal cord.

Front 7

The Cerebrum is made up of the following (5):

Back 7

1)cerebral cortex (outer layer)
2)convolutions (gyri)are the elevated portions
3)fissures (sulci)which are the depressions
4)hemispheres
5)lobes

Front 8

Dendrite

Back 8

Root like structures that receive impulses and conduct them to the cell body.

Front 9

Nerve

Back 9

One or more bundle of impulse-carrying fibers that connect the brain and spinal cord.

Front 10

Spinal nerves

Back 10

There are 31 pairs of spinal nerves enclosed in the spinal cord.

Front 11

What does the frontal lobe of the Cerebrum do?

Back 11

controls motor function

Front 12

Ganglia

Back 12

masses of nervous tissue located outside the brain and spinal cord.

Front 13

Neuron

Back 13

Individual nerve cell

Front 14

Thalamus

Back 14

relays sensory impulses to cerebral cortex.

Front 15

Pituitary gland

Back 15

Master gland (controlling center) located in the brain)

Front 16

What does the parietal lobe of the Cerebrum do?

Back 16

receives and interprets nerve impulses from the sensory receptors.

Front 17

Hypothalamus

Back 17

activates and controls the peripheral autonomic nervous system, endocrine processes, body temperature, sleep and appetite.

Front 18

Plexus

Back 18

A large network of nerves, i.e. brachial plexus - arms, chest, shoulders

Front 19

What does the occipital lobe of the Cerebrum do?

Back 19

controls eyesight

Front 20

Impulse

Back 20

Wave of excitation transmitted through nerve fibers and neurons

Front 21

Pons

Back 21

Bridge tissue connecting two parts of an organ

Front 22

Axon

Back 22

conducts impulses away from the cell body

Front 23

What does the temporal lobe of the Cerebrum do?

Back 23

controls the senses of hearing and smell

Front 24

Medulla oblongata

Back 24

The most vital part of the brain, controls basic life functions including muscles of respiration, heart rate, and blood pressure.

Front 25

Reflex

Back 25

Autonomic, involuntary response to some change, either inside or outside the body.

Front 26

Brainstem

Back 26

made up of the midbrain, pons and medulla oblongata. Connects the cerebral hemispheres with the spinal cord

Front 27

Name the 4 lobes of the Cerebrum.

Back 27

1)frontal lobe
2)parietal lobe
3)occipital lobe
4)temporal lobe

Front 28

Meinges

Back 28

Three layers of connective tissue membrane that enclose the brain and spinal cord.

Front 29

Spinal cord

Back 29

Conducts sensory and motor impulses to and from the brain
