The Nervous System Study Guide

Division of the ANS that generally prepares the body for increased energy expenditure.

• Parasympathetic division

• Autonomic nervous system

• Sympathetic division

• Central nervous system

Nerves that originate from the spinal cord.

• Brain cells

• Spinal nerves

• Muscles

• Blood vessels

A neuron that conducts action potentials from one neuron to another within the CNS.

• Interneuron

• Motor neuron

• Sensory neuron

• Assocation neuron

An axon has a myelin sheath produced by Schwann cells. Where is this axon located?

• PNS

• CNS

• Spinal cord

• Blood vessels

What binds together and insulates CNS neurons?

• Astrocyte

• Neuromuscular Junction

• Schwann Cell

• Oligodendrocyte

Bundles of neuron axons and their coverings, which are found outside the CNS

• Nerves

• Muscles

• Tendons

• Synapses

PNS neurons that transmit action potentials from the CNS to skeletal muscles.

• Autonomic Motor Nervous System

• Sensory Nervous System

• Somatic Motor Nervous System

• Parasympathetic Nervous System

Nerves that originate from the brain

• Muscles

• Cranial nerves

• Blood vessels

• Ligaments

When you flex your forearm, which division of the PNS is being used?

• Autonomic Division

• Somatic Division

• Sensory Division

• Efferent Division

What would be the most specific way to describe the part of the PNS that is being used?

• Somatic Motor Nervous System (SMNS)

• Autonomic Nervous System (ANS)

• Central Nervous System (CNS)

• Sympathetic Nervous System (SNS)
