Neuron

Question 1

Neuron

Answer 1

Highly specialized to transmit message from one part of the body to another

Question 2

Cell body

Answer 2

Contains the nucleus, metabolic center of the cell

Question 3

Dendrites

Answer 3

Convey incoming message toward the cell body

Question 4

Axons

Answer 4

Transmit nerve impulses away from the cell body

Question 5

Axonal terminal

Answer 5

Branches at the end of an axon

Question 6

Neurotranmitters

Answer 6

Chemicals that are contained within axonal terminals and are when the nerve impulses reaches the axonal terminal

Question 7

Synapse

Answer 7

The region of communication bw neurons

Question 8

Myeline sheath

Answer 8

Covers the nerve fiber, protects and insulates. Increases transmission rate of nerve impulses

Question 9

Schwann cells

Answer 9

Specialized supporting cells that wrap themselves around axon outside the cns, forms the myeline sheatg

Nodes of ranvier

Answer 10

Gaps bw schwan cell

Carry impulses from sensory receptors to CNS

Question 12

Motor or efferent neuron

Answer 12

From Cns to the viscera and muscles and gland

Question 13

Imterneurons
