Front 1

CNS

Back 1

Brain and spinal cord

Front 2

Cerebellum

Back 2

Controls your balance and posture

Front 3

Cerebrum

Back 3

Controls your thinking, memory, speaking and movement-identifies information identified by your sense organs

Front 4

Medulla/Brain stem

Back 4

controls your heartbeat, breathing and blood pressure

Front 5

Pituitary Gland

Back 5

Regulates the functions of other endocrine glands. Produces hormones, pituitary growth, anti-diuretic, thyroid-stimulating

Front 6

Hypothalamus

Back 6

Responsible for hormone production. Produces a wide range of neurohormones

Front 7

Spinal cord

Back 7

Send messages to the brain, and from brain to PNS

Front 8

PNS

Back 8

Nerves, somatic and autonomic nervous systems.

Sympathetic and parasympathetic nervous systems

Front 9

Neurotransmitter

Back 9

Chemical located at synaptic terminal that converts electrical impulse 'info', so that it can diffuse across the synapse to the next neuron.

Front 10

Motor neurons

Back 10

Take messages from CNS to effectors

Front 11

Sensory neurons

Back 11

convert external stimuli and transmit those messages to CNS

Front 12

relay neurons

Back 12

In CNS only, connect motor and sensory together

Front 13

Axon

Back 13

transmits info from dendrites to axon terminal

Front 14

Myelin sheath

Back 14

For protection and insulation of axon. Keeps electrical signals inside axon and helps them move faster.

Front 15

Dendrites

Back 15

Pass info from other neutrons into itself for transmission to another neuron

Front 16

cell body

Back 16

production of proteins

Front 17

Thyroid-stimulating

Back 17

changes rate of thyroxine. Produced by pituitary gland

Front 18

Anti-diuretic

Back 18

reduces amount of water reabsorbed by kidneys. Produced by pituitary gland

Front 19

Pituitary growth

Back 19

Stimulates muscle growth and controls bone size. Produced by pituitary gland.

Front 20

Front 21

Thyroxine

Back 21

Metabolism, physical and mental development. Produced by the thyroid gland.

Front 22

Cacitonin

Back 22

decreases amount of calcium in the blood. Produced by thyroid gland
