Central Nervous System -CORRECT ANSWER (CNS) Consists of the brain and spinal
cord
Peripheral Nervous System -CORRECT ANSWER (PNS) Consists of all nerves and
receptors that are not part of the brain or spinal cord.
What are the four major parts of the brain? -CORRECT ANSWER Cerebrum,
Cerebellum, Brain Stem, and Diencephalon
What are the three functions of the nervous system? -CORRECT ANSWER Sensory
Function (Afferent), Integrative Function, and Motor Function (Efferent)
What is a Sensory Function (Afferent)? -CORRECT ANSWER It carries information
from the PNS to the CNS.
What is an Integrative Function? -CORRECT ANSWER When the brain is processing
the information.
What is a Motor Function (Efferent)? -CORRECT ANSWER It carries the motor
commands from the CNS to the PNS.
What are the two types of cells in the nervous system? -CORRECT ANSWER Neurons
and Neuroglia (glial cells).
Neurons -CORRECT ANSWER It transmits the nerve impulse. Does not replicate nor
replace themselves when injured.
Neuroglia (glial cells) -CORRECT ANSWER They are the most abundant nerve cell
that supports and nourishes the neurons.
Parts of a Neuron -CORRECT ANSWER Dendrites, Cell body, Ganglion (ganglia),
Axon, Axon terminals (synaptic knobs), Myelin sheath (myelin), Schwann cells, and
Nodes of Ranvier.
Dendrites -CORRECT ANSWER Branchlike part of the neuron that transmits the nerve
impulse toward the cell body.
