Nervous System

Front 1

Autonomic nervous system

Back 1

the system controlling involuntary actions such as heartbeat

Front 2

Axon

Back 2

a nerve fiber that sends nerve impulses away form the cell body

Front 3

Brain stem

Back 3

part of the brain where the spinal cord enters the skul; it controls the body's vital functions, such as breathing, blood pressure and heart rate

Front 4

Cell body

Back 4

the part of the neuron that contains the nucleus

Front 5

Central Nervous System (CNS)

Back 5

qthe brain and the spinal cord

Front 6

Cerebellum

Back 6

part of the brain that is responsible for coordination and balence

Front 7

Cerebrum

Back 7

part of the brain that controls conscious thoughts, controls the movement of every body part, and receieves sensory messages from each body part

Front 8

Dendrites

Back 8

branches form the cell body and receives messages from other neurones

Front 9

Effector

Back 9

muscles or glands that put the messages into effect

Front 10

Medulla

Back 10

the lower half of the brain stem

Front 11

Motor neurones

Back 11

nerve cells that crarry messages from the CNS to effectors

Front 12

Myelin sheath

Back 12

the insulating layer that covers a neurone

Front 13

Nerve impulses

Back 13

the electrical message carried by a nerve cell

Front 14

Neurone

Back 14

a nerve cell

Front 15

Neurotransmitter

Back 15

a chemical message released at the end of an axon to be receieved by the next neurone's dendrites

Front 16

Optic nerve

Back 16

the nerve that carries messages to the brain form the retina at the back of the eye

Front 17

Parasympathetic nervous system

Back 17

part of the nervous system that slows the body down and controls it when resting

Front 18

Peripheral nervous system (PNS)

Back 18

the nerves that carry messages to and from the central nervous system and other parts of the body
