sympathetic

Question 16

rest and digest

Answer 16

parasympathetic

Question 17

CNS

Answer 17

-brain + spinal cord
-integrative function: sensory input to motor action
-source of thoughts, emotions and memories

Question 18

PNS

Answer 18

all nervous tissues outside of the CNS
-has nerves- bundles of axons
*12 pairs of cranial nerves from the brain
*31 pairs of spinal nerves from the spinal column

2 divisions:
sensory (afferent)
motor (efferent)

Question 19

sensory (afferent) division

Answer 19

conveys input from sensory receptors to CNS
-somatic senses
-special senses

Question 20

motor (efferent) division

Answer 20

-conveys output from CNS to effectors (muscles and glands)
-somatic nervous system
-autonomic nervous system

Question 21

somatic nervous system

Answer 21

-conveys output from CNS to skeletal muscles
-voluntary

Question 22

ANS

Answer 22

conveys output from CNS to smooth muscle, cardiac muscle, and glands
-involuntary

Question 23

enteric nervous system

Answer 23

regulate the activity of the smooth muscles and glands of the GI tract
-has innervation from both sympathetic and parasympathetic nervous system

Answer 33

-primary transmitter at the ans ganglia -primary excitatory transmitter to smooth muscle

Question 34

ATP

Answer 34

act as transmitter or co-transmitter at many ANS effector synapses
