the foramen magnum Answer - brain
spinal cord
What are the two divisions of the peripheral nervous system? Answer -
autonomic nervous system
,somatic nervous system
In what division of the PNS, can motor stimuli be either excitatory or
inhibitory? Answer - autonomic nervous system
In what division of the PNC, can motor stimuli only be excitatory in nature?
Answer - somatic nervous system
What division of the peripheral nervous system contains the sympathetic
nervous system and the parasympathetic nervous system? Answer -

other neurons, muscle fibers, or glands? Answer - axon
Effectors refer to _____________ or __________ Answer - muscle
gland
The junction between neurons and other neurons or effectors is known as the:
