Card Set Information
Spinal and cranial nerves are all motor neurons that affect skeletal muscles
Spinal and cranial nerves carry both autonomic and somatic nerve fibers
Spinal and cranial nerves include both sympathetic and parasympathetic nerves on every branch?
Spinal and cranial nerves employ a pathway that includes presynaptic and postsynaptic nerurons?
Pupil of eye Sympathetic NS & Parasympathetic NS
Blood Glucose Sympathetic NS and Parasympathetic NS
Urinary function Sympathetic NS and Parasympathetic NS
:decrease urine output
Digestive function Sympathetic NS and Parasympathetic NS
: decrease activity, constricts sphincters
: increase peristalsis; release of enzymes; releases sphincters
Heart rate Sympathetic NS and Parasympathetic NS
: increase rate and force coronary
: decrease rate and force coronary vesselse constrict
Blood Pressure Sympathetic NS and Parasympathetic NS
S:dialates visceral vessels; increase BP diverts blood flow to brain muscle and heart
metabolic rate Sympathetic NS and Parasympathetic NS
fats Sympathetic NS and Parasympathetic NS
breaks down ( mobilizes fat)
Parasympathetic NS: -
bronchioles Sympathetic NS and Parasympathetic NS
Sweat Glands Sympathetic NS and Parasympathetic NS
Penis/Clitoris & Vagina Sympathetic NS and Parasympathetic NS
ejaculation/ mucus production
arrector pilli muscle Sympathetic NS and Parasympathetic NS
The parasympathetic nervous nervous system arises from the
Brain stem and sacral spinal cord
the sypathetic nervous system arises from the
thoracic and lumbar region
what are characteristics of the neurotransmitter of the ANS
acetylcholine is the only neurotransmiteter of the parasympatheticNS
most sympathetic postganglionic axons release norepinepherine
most sypatheitic preganglionic axons release acetylcholine
can the same organ be stimulated by both sympathetic and parasympathetic innervation?
Which levels of control DOES NOT regulate the autonomic nervous system?
which branch of the autonomic NS has ganglia near the spinal cord, and tends to inhibit gland secretionwhile stimulating hormomal secretions of the adrenal medulla
which of the autonomic NS has ganglia near the spinal cord and tends to inhibit gland secretionwhile stimulating hormonal secretions of the adrenal medulla
what makes cranial nerves I and II relatively unique?
which of the cranial nerves are primarily motor?
where in the human nervous system are unmyelenated fibers?
post ganglionic autonomic nervous system
which system tends to allow for normal urination and defication?
in what way does nicotine mimic acetylcholine?
activates acetylcholine repceptors on the postsynaptic fiber
sympathetic and parasympathetic systems
some organs or tissues are only stimulated by sympathetic fibers
some organs or tissues are only stimulated by parasympathetic fibers
most visceral organs show antagonist actions with sympathetica and parasympathetic innervation
best discription of autonomic nervous system
