Neuron Terms

Question 1

refers to the study of the parts and functions of neurons

Answer 1

neuroanatomy

Question 2

a nerve cell; the basic building block of the nervous system

Answer 2

Neuron

Question 3

rootlike parts of the cell that branch out from the cell body. They grow to make synaptic connections
with other neurons.

Answer 3

Dendrites

Question 4

Cell body; contains nucleus

Answer 4

Soma

Question 5

wirelike structure ending in the terminal buttons that extends from the cell body.

Answer 5

Axon

Question 6

a fatty covering around the axon of some neurons that speeds up neural impulses.

Answer 6

Mylein Sheath

Question 7

Branch end of Axon that contains vesicles of neurotransmitters

Answer 7

Terminal buttons (Ends)

Question 8

name of the chemical messengers that cross the synapse between the sending neuron and travel across the synapse binding to receptor sites on the receiving neuron.

Answer 8

Neurotransmitters

Question 9

Cells that provide various support for neurons. They supply nourishment to neurons, remove neurons waste products, and provide insulation around many axons.

Answer 9

Gilal Cells

Question 10

Produce the Mylien Sheath

Answer 10

Schwann Cells

Question 11

gaps in the myelin sheath coating on the neural axon. Allows action potential to produce quickly down the axon

Answer 11

Node of Ranvier

Question 12

the space between the terminal buttons of one neuron and the dendrites of the next neuron.

Answer 12

Synapse

Question 13

A neurotransmitter’s reabsorption by the sending neuron

Answer 13

Reuptake

Question 14

triggering the release of chemicals called neurotransmitters that diffuse across a synapse to communicate with other neurons.

Answer 14

Action Potential

Question 15

a period of inactivity after a neuron has fired

Answer 15

Refractory Period

Question 16

nerve impulses that will jump from gap to gap along myliented axons increasing conductivity velocity of action potential.

Answer 16

Salatory condition
