What are dendrites?
Part of a neuron that carries messages
away from the cell
What is an axon?
Substance released by axon terminal that
triggers a nerve impulse
What is a neurotransmitter?
Point at which an impulse from one
nerve cell is communicated to another
nerve cell
What is synapse?
Axons covered with this material
appear white and conduct impulses
faster than axons not covered with this
material
What is the myelin sheath?
Division of the nervous system that
consists of brain and spinal cord
What is the CNS or central nervous
system?
Division of the nervous system that
consists of cranial and spinal nerves
What is the PNS or peripheral nervous
system?
Division of the nervous system that is
not under voluntary control and includes
sympathetic and parasympathetic
nervous systems
What is the autonomic nervous system?
Division of the PNS that is under
voluntary control
What is the somatic nervous system?

known as ________.
What are effectors?
Sensory neurons are also called
_________ neurons.
What is afferent?
Motor neurons are also called
__________ neurons.
What is efferent?
The first step in a reflex arc, could be
sense organs.
What are receptors?
Middle step in a reflex arc, between
afferent and efferent neurons

LOBE of the brain that is associated
with memory, emotions, and decisionmaking, contains primary motor cortex
What is the frontal lobe?
LOBE of the brain that integrates
sensory information and spatial
awareness
What is the parietal lobe?
Part of the brain that regulates
temperature, thirst, hunger and other
drives
What is the hypothalamus?
Deep groove that divides the frontal and
parietal lobes
What is the central sulcus?
Large fiber tract that joins the two
cerebral hemispheres and allows
communication between them
