The Nervous System

Front 1

Autonomic nervous system

Back 1

The part of the peripheral nervous system that controls the glands and muscles of the internal organs(such as the heart).

Front 2

neuron

Back 2

a nerve cell; the basic bulding block of the nervous ststem.

Front 3

myelin

Back 3

a layer of fatty tissue segmentally encasing the fibers of many neurons; enables vastly greater tansmission speed of neural imputses as the impulse hops from one node to the next.

Front 4

sensory neuron

Back 4

neurons that carry incoming information from the sense receptors to the central nervous system.

Front 5

interneuron

Back 5

central nervous system neurons that internally communicate and intervene between the sensory inputs and motor outputs.

Front 6

motor neuron

Back 6

the neurons that carry outgoing information from the central nervous system to the muscles and glands.

Front 7

reflex action

Back 7

a simple, automatic, inborn response to a sensory stimulus, such as the kee-jerk response.

Front 8

receptor cells

Back 8

receives the neural transmitions.
