Chapter 8 Nervous System Knowledge

interneurons

are found only in the central nervous system

Nissl bodies

Clusters of rough endoplasmic reticulum and free ribosomes are known as

is fast acting

In general, the nervous system

astrocytes

The largest and most numerous of the glial cells in the central nervous system are the

oligodendrocytes

The myelin sheaths that surround the axons of some of the neurons in the CNS are formed by

Schwann cells

The neurilemma of axons in the peripheral nervous system is the outer layer of

afferent division

The part of the peripheral nervous system that brings information to the central nervous system is the

multipolar

Most neurons in the brain are

bipolar

Neurons that have one axon and one dendrite with the soma between them are called

multipolar

Neurons that have two or more dendrites and a single axon extending away from the soma are called

astrocytes

The glial cells responsible for maintaining the blood-brain barrier are the

microglia

Small phagocytic glial cells, which are derived from white blood cells, are called

sending signals to muscles

a function of the efferent division of the nervous system?

collaterals

Branches that sometimes occur along the length of an axon are called

peripheral

All of the nervous tissue outside of the central nervous system comprises the ________ nervous system.

tracts

Bundles of CNS axons that share a common origin, destination, and function are called ________.

afferent

The ________ division of the nervous system brings sensory information to the central nervous system

autonomic

The ________ nervous system provides involuntary regulation of smooth muscle, cardiac muscle, and glandular activity.

central nervous system

The brain and spinal cord comprise the

dendrites

The branching structures that, together with the cell body, are sensitive to chemical, mechanical, or electrical stimulation are called

ependymal cells

Which neuroglial cells produce CSF in some regions of the brain
