Nervous System

What is the part of the neuron that receives impulses?

• axon

• synapse

• cell body

• nodes of Ranvier

This carries the impulse from the cell body and is covered in a myelin sheath

• axon

• nodes of Ranvier

• Schwann cells

• dendrites

These neurons receive impulses from sensory neurons

• motor neurons

• interneurons

• sensory neurons

• mixed neurons

Why doesn't an action potential travel back up the axon of the neuron?

• because of the valve

• the axon is repolarized

• it is in the relative refractory period

• it is in the absolute refractory period

This division of the peripheral nervous system contains receptors and nerve fibers that carry information from the body to the CNS

• sensory division

• motor division

• somatic system

• autonomic system

This system can be controlled, AKA the voluntary nervous system
