QuestionAnswer
efferent leaves via ventral horn
number of peripheral nerves in somatic nervous system 1
number of peripheral nerves in autonomic nervous system 2, pre and post ganglion
location of cell bodies of parasympathetic CN 3, 7, 9, 10, S2,3,4
location of cell bodies of sympathetic T1-L2
2 different paths of sympathetic nerve 1. ventral root -> white ramus -> sympathetic chain ganglion (synapse) -> grey ramus -> target cell 2. ventral root -> white ramus -> sympathetic chain -> collateral ganglion -> target cell
varicosity enlarged vessel containing transmitter molec
__cells in adrenal medulla contains hormones chromaffin
transmitter for pre/post ganglion of somatic nerve somatic has only 1 nerve, releases ACh
transmitter for pre/post ganglion of parasympathetic nerve pre-ACh, post-ACh
transmitter for pre/post ganglion of sympathetic nerve pre-ACh, post-NE
ACh broken down by and to and what happens to the products acetylcholinesterase, choline + acetate, choline taken back into presynaptic neuron
how is ACh made acetyl CoA + choline -> ACh
fate of NE after it gets released to synptic gap taken back into presynaptic
different ACh receptors Nicotinic (NM, NN) Muscarinic (M1,,,M5)
different adrenergic receptors alpha(alpha1 and alpha2)22 beta(beta1,, beta3)
Nm is nicotinic receptor on muscle
Nn is nicotinic receptor on nervous tissue
adrenal medulla has __ receptor Nn
adrenergic receptor ionotropic or metabotropic metabotropic
cholinergic receptor ionotropic or metabotropic nicotinic iono, muscarinic metabo
nicotinic receptor has _ peptide subunits 5
muscarinic receptor has __ peptide subunits 7
autonomic ganglia have __ receptor Nn
effect of para, symp on pupil symp-dilate para-constrict
efect of para, symp on ciliary muscle para-contract symp-relax
effect of para, symp on HR, and force of heart beat para-dec HR, no change in force symp-inc HR, inc force
effect of para and symp on salivary gland para-produce saliva symp-inhibit saliva
effect of para and symp on stomach, pancreas para-inc. secretion symp-dec. secretion
effect of para and symp on sweat gland para-no effct symp-inc sweating
effect of para and symp on BV para-no effect symp-constriction
effect of para and symp on sphincters para-relax symp-contraction
effect of para and symp on lungs para-airway constriction symp-airway dilation
effect of para and symp on urinary bladder para-contraction symp-no effect
when bladder is full __ receptor sends info to the brain which sends information back to the bladder via __ which causes __ to bladder. stretch, efferent parasympathetic, contraction
external sphincter of urin. bladder is innervated by somatic nerve
BP is calculated by HR * force * resistance
shivering is autonomic or somatic somatic
temperature receptors in skin are cold receptors
temperature sensor in hypothalamus are heat receptors
heat receptors in hypothalamus
cold receptor in skin
thermoreceptors send info to hypothalamus
myasthenia gravis result of defected _ Nm
symp innervation damaged cause miosis (pupil constriction), ptosis(eyelid droops), anhydrosis(no sweating), flushing (BV dilate)
