|
where do the para NS pregang neurons originate in the SC?
|
The cranial and sacral nerves (top and bottom)
|
|
|
what and where is the length of the fibers in the para NS?
|
the LONG pregang fibers go to the SHORT post gang fibers. the post ganglia synpase near the effector organ (creates a localized reponse)
|
|
|
what NT is released at the synpases in the para system?
|
both synpases at the pre and post ganglionic synapses release Ach
|
|
|
where do the symp NS pregang fibers originate?
|
Thoracic(T1-T12) and lumbar(L1-L3) nerves
|
|
|
what and where is the length of the fibers in the symp NS?
|
short preganglionic fibers and long postganglionic fibers.
the ganglia are near the spinal cord and form the sympathetic chain (the chain is where the pre-gang synapse) |
|
|
what NT is released at the synpases in the symp NS?
|
pregang release Ach
postganglionic release Ner |
|
|
what NT is released at the synapses in the adrenal system?
|
pregang releases Ach onto the adrenal gland which releases Epi>Ne into the bloodstream
