Back

Neurons and Neuroglia

Front

Function of Neurons

Back

Conduct impulses around 10% of the body

Front

Function of Neuroglia

Back

''Nerve glue''- support, insulate and protect neurons takes up 90% of the body

Front

Neuron function

Back

Dendrites send in impulses to cell body and nuclues, the impulse travels down the axon into axon terminals which send impulses out

Front

How are neurons classified?

Back

Afferent Neurons- carry impulses to CNS

Efferent neurons- Carry away from CNS

Interneurons- connect aff and eff neurons

Front

What are axons wrapped in

Back

Myelin which is formed by schwann

Front

What is Myelin's function

Back

helps the nerve impulses travel more quickly

Front

Autonomic Nervous system

Back

Involuntary muscle control
