Questions and Answers Graded A+
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.
Cell body - Correct answer-Located in the CNS and contains DNA.
Ganglion (ganglia) - Correct answer-Group of cell bodies in the PNS.
Axon - Correct answer-Carries impulses away from cell body to the target organ.
Axon terminals (synaptic knobs) - Correct answer-Ends of the axon that stores
neurotransmitters.
