The Brain And Nervous System (Ls1.d)

Front 1

An electric and chemical message that travels from neuron to neuron

Back 1

nerve impulse

Front 2

An action or change in behavior that occurs in reaction to a stimulus.

Back 2

response

Front 3

A space where information is transmitted from one neuron to the next; the place where an axon and dendrite meet

Back 3

synapse

Front 4

Neurons that carry information from the brain and spinal cord to the muscles and tell them to move.

Back 4

motor neuron

Front 5

The part of the nervous system that carries messages back and forth between the brain and every other part of the body. Nerves are made up of neurons.

Back 5

nerve

Front 6

The part of the brain that controls motions, balance and coordinates complex movements

Back 6

cerebellum

Front 7

Neurons that detect stimuli and then send messages to the brain and spinal cord.

Back 7

sensory neuron

Front 8

Branchlike structures on a neuron that receive messages from other neurons.

Back 8

dendrite

Front 9

The part of the brain that controls things like thinking, memories, and your senses.

Back 9

cerebrum

Front 10

A signal from the environment (wave, chemical, or pressure) that is detected by the nervous system.

Back 10

stimulus

Front 11

A neuron that is connected to other neurons, not to sense organs or muscles

Back 11

interneuron

Front 12

The part of your nervous system that controls voluntary actions such as using a fork or tying your shoes.

Back 12

somatic nervous system

Front 13

Nerves that run up and down the length of the back and transmit most messages between the body and brain

Back 13

spinal cord

Front 14

A simple, automatic response to a sensory stimulus

Back 14

reflex

Front 15

Part of the brain that connects to the spinal cord; controls automatic functions (such as breathing and heart rate)

Back 15

brain stem

Front 16

The part of your nervous system that controls automatic activities such as heart rate and breathing.

Back 16

autonomic nervous system

Front 17

A thin layer on the back of the eye that contains sensory neurons. The retina gathers light (a stimuli) and sends messages to the brain about the light.

Back 17

retina

Front 18

The portion of the nervous system that includes the brain and the spinal cord

Back 18

central nervous system

Front 19

A curled tube in the ear that contains the sensory receptors for hearing. They also control your balance.

Back 19

cochlea

Front 20

The part of the nervous system consisting of all nerves that are not part of the brain or spinal cord.

Back 20

peripheral nervous system

Front 21

When your nervous system controls your other systems to keep things like your heartbeat and breathing constant.

Back 21

homeostasis

Front 22

A cell that carries information through the nervous system.

Back 22

neuron

Front 23

A long, threadlike part of a neuron that carries nerve impulses away from the neuron cell body, and transmits the impulses to other neurons or muscles

Back 23

axon

Front 24

The center of the nervous system, where information is processed, memories are stored, and emotions, behavior, and physical actions are controlled

Back 24

brain

Front 25

The center of the nervous system, where information is processed, memories are stored, and emotions, behavior, and physical actions are controlled

Back 25

brain
