Contains the CNS, PNS, and enteric NS? - Answer - : nervous
system
Primary cell unit in the nervous system called nerve fibers are
also called? - Answer - : neurons
Job of the neuron is to? - Answer - : generate electrical
impulses and carry information
Supportive cells in the nervous system are called? - Answer - :
neuroglia
The effect of the neurons are carried out by? - Answer - :
effector organs
Three types of neurons we have are? - Answer - : sensory,
motor, associational
Sensory nerves carry? - Answer - : afferent impulses or
incoming information, from the body back to the CNS,
ascending or upgoing tracts
, 1
Motor nerves carry? - Answer - : efferent impulses or outgoing
information, away from the CNS to the effector organs,
descending or outgoing tracts

neuron to neuron sometimes called interneurons
Name the nervous system:
- connects CNS to our skeletal muscle
- usually refers to actions of organ effectors under our
*voluntary* control
- includes both afferent and efferent tracts
- Ex: all *skeletal muscle*: biceps, bladder sphincter, muscle -
Answer - : somatic nervous system
This system falls under the PNS and is responsible for our
*voluntary control* of things such as skeletal muscle? - Answer
- : somatic nervous system
This system falls under the PNS and is responsible for things we
do not have to think about such as changes in HR, BP, or pupil
dilation? - Answer - : autonomic nervous system
Name the two different systems which fall under the autonomic
nervous system? - Answer - : sympathetic & parasympathetic
Sympathetic is responsible for? Hint: *Gas Pedal* - Answer - :
speeding up stuff
Parasympathetic is responsible for? *Brake Pedal* - Answer - :
slowing down stuff
