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
