Is the following found in (a) the PSNS or (b) the SNS:
long pre-ganglionic fiber + short post-ganglionic fiber
Give this one a try later!
(a) PSNS
SNS post-ganglionic neurons are:
a) cholinergic
b) adrenergic
c) either a or b
Give this one a try later!
, b) adrenergic
T/F: "All components of the autonomic nervous system are peripheral (not central)."
Give this one a try later!
False, there are central and peripheral components of the autonomic
nervous system
List four differences between SNS and PSNS nerves/ fibers
Give this one a try later!
- area nerves leave the CNS (cranial & sacral vs. thoracic & lumbar)
- relative ganglia location (end organ vs. spinal cord)
- length of pre- and post-ganglionic fibers (long->short vs. short->long)
- number of post-ganglionic fibers per pre-ganglionic fiber (one:one vs.
one: many)
Where does the ACh that activates the M receptors on endothelial cells of blood
vessels come from?
Give this one a try later!
circulating molecules
(bc they're not innervated by cholinergic nerve fibers)
