What is acetylcholine (Ach) - ANS/the most plentiful neurotransmitter in
the body, released by nerve cells, especially active in neuromuscular
junctions (cardiac, skeletal, and smooth)
Excitatory: muscle contraction
Inhibitory: reduction of signaling, like reduction of HR
Which receptors pick up ACh - ANS/cholinergic receptors
Sarin gas - ANS/inhibits AChl; interferes with the degradation of ACh in the
synapse (neuromuscular junction); leads to muscle tetani, inability to
control the muscles.
Atropine - ANS/inhibits muscarinic ACh receptors
CNS - ANS/spinal cord and tissue, sensory info, executing motor
commands, higher functioning, both cell bodies and axons
PNS - ANS/all neural tissue except CNS, mainly composed of nerves
grouped together in bundles of axons
the only place to find cell bodies are in ganglions
, Afferent neurons - ANS/sensory neurons
3 classes of afferent neurons - ANS/somatic
visceral
special
somatic afferent neurons - ANS/neurons of the bones, muscles, and skin
visceral afferent neurons - ANS/neurons of the organs
special afferent neurons - ANS/neurons involved in hearing, sight, taste,
smell
interneurons - ANS/only located in the CNS
efferent neurons - ANS/motor neurons
2 classes of efferent neurons - ANS/somatic and visceral
