KHP 205: Chapter 8 The Nervous System

The part of the nervous system that consists of nerves that branch out from the CNS (central nervous system) and connect to other body parts

• Sympathetic nervous system

• Parasympathetic nervous system

• Autonomic nervous system

• Peripheral nervous system

The membrane that surrounds an entire nerve is the:

• perineurium

• epineurium

• endoeurium

• neurilemma

The neurons that conduct impulses to the spinal cord and brain are the:

• motor neurons

• sensory neurons

• interneurons

• association neurons

The fibers that conduct impulses away from the cell body are the:

• dendrites

• axons

• cell bodies

• neurilemma

The fatty material that coats some axons and speeds nerve impulse conduction is called ___________.

• Actin

• Myelin

• Dendrite

• Myosin

Which division of the nervous system exclusively controls skeletal muscles?

• Peripheral

• Central

• Somatic

• Autonomic

Which of the following is NOT in the central nervous system?

• Tract

• White matter

• Interneuron

• Collateral ganglion

The part of the peripheral nervous system that controls conscious activities

• Autonomic nervous system

• Somatic nervous system

• Sympathetic nervous system

• Parasympathetic nervous system

During the rising (depolarizing) phase of an action potential, ions of the element ___________ enter the neuron through channels.

• Sodium

• Potassium

• Calcium

• Chloride

What are the two divisions of the autonomic nervous system?

• central and peripheral

• parasympathetic and sympathetic

• brain and spinal cord

• neurons and glial cells
