nervous system?
brain and spinal cord - Correct answer What are the parts of the central nervous
system?
nerves - Correct answer what is included in the peripheral nervous system?
somatic and autonomic - Correct answer What are the two divisions of the
peripheral nervous system?
somatic nervous system - Correct answer nerves that serve skin, skeletal
muscle, and tendons
-voluntary control
autonomic nervous system - Correct answer regulates activity of cardiac and
smooth muscles, organs, and glands
-involuntary control
sympathetic and parasympathetic - Correct answer what are the two divisions of
the autonomic nervous system?
sympathetic nervous system - Correct answer promotes activities associated
with emergency
-fight or flight
parasympathetic nervous system - Correct answer active under normal
conditions

neurons - Correct answer nerve cells that transmit impulses
axon, cell body, dendrites - Correct answer what are the 3 parts of a neuron?
sensory neuron, motor neuron, interneuron - Correct answer what are the 3
kinds of neurons?
sensory neuron - Correct answer sensory receptor (PNS to CNS)
interneuron - Correct answer entirely within CNS
motor neuron - Correct answer CNS to PNS to effector (muscle fiber, organ,
gland)
neuroglia - Correct answer nonconducting nerve cells that support neurons
nerve signals - Correct answer action potentials traveling along a neuron ; they
convey info
action potential - Correct answer a brief change in electrical conditions at a
neuron's membrane
refractory period - Correct answer portion of axon immediately following the
action potential
sympathetic division - Correct answer which subdivision of the autonomic
nervous system is responsible for fight or flight?

depolarization - Correct answer sodium gates open (-40mv)
Repolarization - Correct answer potassium gates open (+30MV)
stimulus - Correct answer activates neuron and begins action potential if
threshold is met (-40mv)
