Back 4

Major division of the brain

Front 5

Frontal Lobe

Division of the brain that contains the motor strip and frontal association area

Front 6

Parietal Lobe

Back 6

Area of the brain that contains the sensory strip

Front 7

Motor Strip

Back 7

Band running down the side of the frontal lobe that controls all bodily movemments (called motor functions)

Front 8

Sensory Strip

Back 8

Band running down the side of the parietal lobe that registers and provides all sensation

Front 9

Are of the brain that interprets visual information

Front 10

Temporal Lobe

Back 10

Area of the brain responsible for hearing and some speech functions

Front 11

Frontal Association Area

Back 11

The forward portion of the brain that engages in elaborate associations or mental connections; It plays an important part in integrating personality and in forming complex thoughts.

Front 12

Dominance

Back 12

Either the right or left hemisphere is dominant in each individual; hence one of them is preferred and controls the majority of actions performed

Front 13

Cerebral Cortex

Back 13

the unit that covers the lower brain and controls mental processes such as thought

Front 14

Lower Brain

Back 14

Basic "animal" units common to animals and humans that regulate basic functions such as breathing

Front 15

Thalamus

Back 15

the portion of the lower brain that functions primarily as a central relay station for incoming and outgoing messages from the body to the brain and the brain to the body

Front 16

Cerebellum

Back 16

the portion of the lower brain that coordinates and organizes bodily movements for balance and accuracy.

Front 17

Hypothalamus

Back 17

the portion of the lower brain that regulates basic needs (hunger, thirst) and emotions such as pleasure, fear, rage, and sexuality

Front 18

Reticular Activating System
Reticular Formation
RAS

Back 18

The alertness control center of the brain that regulates the activity level of the body

Front 19

Neuron

Back 19

A nerve cell, which transmits electrical and chemical information (via neurotransmitters) throughout the body

Front 20

Dendrite

Back 20

The part of the nerve cell that receives information from the axons of other nerve cells

Front 21

Axon

Back 21

the part of the neuron that carries messages away form the nerve cell to the dendrites on another nerve cell.

Front 22

Synapse

Back 22

The junction point of two or more neurons; a connection is made by neurotransmitters

Front 23

Vesicles

Back 23

Bubblelike containers of neurotransmitters, located at the end of an axon

Front 24

Neurotransmitters

Back 24

Chemicals in the endings of nerve cels that send information across the synapse

Front 25

Acetylcholine

Back 25

Neurotransmitter that regulates basic bodily processes such as movement

Front 26

Dopamine

Back 26

A neurotransmitter involved in the control of bodily movements

Front 27

Endorphins

Back 27

Neurotransmitters that relieve pain and increase our sense of well-being

Front 28

Spinal Cord

Back 28

The part of the body that functions as an automatic "brain" in its own right and is a relay station for impulses to and from the higher brain

Front 29

Reflex

Back 29

An automatic behavior of the body involving movement that is activated through the spinal cord without using the higher brain

Front 30

Hormones

Back 30

chemical regulators that control bodily processes such as emotional responses, growth, and sexuality

Front 31

Glands

Back 31

Units of the body that contain the hormones

Front 32

Endocrine System

Back 32

the system of all the glands and their chemical messages taken together

Front 33

Pituitary gland

Back 33

the master gland of the body that activates other glands and controls the growth hormone

Front 34

Growth Hormone

Back 34

the hormone controlled by the pituitary that regulates the growth process.

Front 35

Thyroid Gland

Back 35

the gland that controls and regulates the speed of bodily processes, called metabolism

Front 36

Metabolism

Back 36

the speed at which the body operates or the speed at which it uses up energy

Front 37

Adrenal Glands

Back 37

the glands that cause excitement in order to prepare the body for an emergency or for some important activity

Front 38

Adrenaine

Back 38

the chemical that prepares the body for emeergency activity by increasing blood pressure , breathing rate, and energy level.

Front 39

Gonads

Back 39

the sex glands that make sperm or eggs for reproduction

Front 40

Androgen

Back 40

the male sex hormone

Front 41

Estrogen
