| Question | Answer |
|---|---|
| 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) |
