ANS Flashcards
somatic motor neurons use what neurotransmitter
acetylcholine
parasympathetic preganglionic neurons use what neurotransmitter
acetylcholine
parasympathetic postganglionic neurons use what neurotrasnmitter
acetylcholine to glands, cardiac, and smooth muscles
symapthetic preganglionic neurons use what neuro transmitter
acetylcholine
sympathetic postganglionic neurons use what neurotransmitter
norepinenephrine, or ACh
sensory neuorns use what neurotrasnmitters
glutamate, atp, substance P
types of receptors for ACh (parasympathetic ALL, and mainly pregang sympathetic
cholinergic (nicotinic, and muscarinic
location of nicotinic receptors
postganglionic dendrites, junctions of skeletal muscles
location of muscarinic receptors for acetylcholine
smooth muscle, cardiac muscle, gland cells, CNS
type of receptors for norepinephrine and epinephrine (alpha and beta)
adrenergic receptors
what type of response does nicotonic receptors cause
excitatory effect
parasympathetic post and preganglionic use what neurotransmitter
ACh
what type of receptors are on the parasympathetic postganglionic neuron
nicotinic receptors
for parasympathetic, what type of receptors are on the target tissue
muscarinic
what receptors are located on the sympathetic postganlionic neuron
nicotinic
what receptors are on the target tissues of the sympathetic postganglionic neurons
muscarinic or adrenergic
Adrenergic receptors are used by what neurons
sympathetic postganglionic neurons
beta receptors has a high affinity for
epinephrine
fight or flight responses
blood vessels to skin and abdominal viserca constrict
blood vessels to skeletal adn cardiac muscles dilate
increase blood glucose levels through breakdown in liver
breakdown fats, increase fatty acid in blood
what do the receptors do in the iris
- sympathetic alpha receptors dilate pupil via the dilator pupillae muscle
- parasympathetic muscarinic M receptors constrict the SPHINCTER PUPILLAE MUSCLE
what Receptors do what on the ciliary muscles
it chnages the shape of lens
sympathic beta receptors RELAX (looking far away)
parasympathetic M receptors CONTRACT (close up)
what receptors do what to the lacrimal glands
sympathetic alpha increase proteins
parasympathetic M receptors increase secretion
in the heart sympathetic receptors do what
sympathetic BETA receptors INCREASE (HR, CONTRACT, conduction,
in the heart what do parasympathetic receptors do
parasympathetic decrease hr, conduction, etc
In the lungs, the bronchial muscles are relaxed by what receptors
sympathetic BETA receptors
in the lungs, the bronchial muscles are contracted by what receptors
parasympathetic MUSCARINIC contract
In the kidneys what do sympathetic beta receptors do what
increase renin secrection, increase bp and increase urine output
in the kidneys what do sympathetic ALPHA receptors do
decrease urine output
in the bladder wall what do receptors do
sympathetic BETA relax
parasympathetic M contract
trigone receptors
alpha - contract
muscrinic - relax
salivary glands RECEPTORS DO WHAT
sympathetic B and ALPha STIMULATE thick
parasympathetic M receptors stimulate thin
For motility in stomach and instentines

para increase
sphincters in stomach, receptors do what
sympathetic ALPHA contract
parasympathietc M relax
what receptors do what for secretion in the intestines
sympathetic ALPHA inhibit

sympathetic Beta receptors relax pregant adn non-pregnant uteri
sympathetic alpha receptors ___ blood vessels while beta receptors ____ other vessels
alpha — constrict
beta— dilate
parasympathetic M receptors do what to blood vessels
vasodilate vessels to salivary glands, and erectile tissues
in skeletal muscles what receptors do what
sympathetic BETA increase contraction speed, thermogenisis, muscles mass, breaking down of glycogen
what increases melatonin production
sympathetic beta receptors
sympathetic beta receptors do what to ADH
increase production to decrease urine and increase water in blood
for mast cells and basophils what do receptors do
sympathetic BETA receptors inhibit histamine
