7Th Grade Science, Eyes & Brain

Front 1

Light-sensitive tissue at the back of the eye that contains rods and cones

Back 1

Retina

Front 2

Small space across which an impulse moves from an axon to the dendrites or cell body of another neuron

Back 2

Synapse

Front 3

Basic functioning unit of the nervous system; made up of a cell body, dendrites and axons

Back 3

Neuron

Front 4

Largest part of the brain where memory is stored, movements are controlled and impulses from the senses are interpreted

Back 4

Cerebrum

Front 5

Major sensory receptor on the tongue; contains taste hairs that send impulses to the brain for interpretation of tastes

Back 5

Taste bud

Front 6

Part of the brain that controls voluntary muscle movements, maintains muscle tone, and helps maintain balance

Back 6

Cerebellum

Front 7

Neuron structure that carries messages away from the cell body

Back 7

Axon

Front 8

Division of the nervous system; made up of nerves outside the CNS; coneects the brain and spinal cord to other body parts

Back 8

Peripheral Nervous System

Front 9

Simple innate behavior, such as yawning or blinking, that is an automatic response and does not involve a message to the brain

Back 9

Reflex

Front 10

Regulation of an organism's internal life, maintaining conditions despite changes in its environment

Back 10

Homeostasis

Front 11

Division of the nervous system made up of the brain and spinal cord

Back 11

Central Nervous System

Front 12

Fluid filled structure in the inner ear in which sound vibrations are converted into nerve impulses that are sent to the brain

Back 12

Cochlea

Front 13

Neuron structure that received messages and sends them to the cell body

Back 13

Dendrite

Front 14

Nasal nerve cell that becomes stimulated by molecules in the sair and sends impulses to the brain for interpretation of odors

Back 14

Olfactory cell

Front 15

Connects the brain to the spinal cord and is made up of the midbrain, the pons and the medulla

Back 15
