effrost are the mscuel

so the brain and spin

sensory galnds feel and it sends it ot hte spin and rbain it proccesses it and then it is going to sne out a singal to the effects which are baisclaly the mucsle or glands.

ther ei the CNa dn PSN the SNs is the rbain andp sinal cord

and TH ePNS is the nerves and ganglia

the sesnosy nervous sytem : afferent nerouv system

afferent is going to mean that it goes from sensosry to the pine so sensour nerovs sytemL affernet nerbvos sytem. thtat recieves sensory ifrmaiton from recpeot ro the spine and brain

somqatic sesnorys tehsm detesds sutmuli and visceral sesnory d=system detes sitmuli we typically do not percieve for exampls singla from the ehart od jdine

So the sensory enrovus systme detes stmili and sends i to the cCentrla nervous system and there is the semoatic where this is recpeotrs that we deted on our own like the fives ense and viscral with is the senory inpur from rep cot of interal or ang abd bloo d ele s

visceral sysneoyr systme detect simuliy we typically do not perceive fro example singal from the heart or kdieys

the snsroy enrovus sytme is afferent nervous sytme reiceves sensory froiation frio tneh sesnsors ot the cna dn theere is omatic hwich detecs stuff we can perice like the five sesn and then there is the visceral sensorys tem that detects things that are not periced like singal from the heart ofkidey ant eri sthe somati ssnesoyr and viscrela sensoty somati and viscerla

so there is sensory nreovys sysme shta is oging or tdeted singla fro the singal and then send it ot eh rbain and then thers is omatn sjenoru which is like stuff we p-erice like isngal from give sens and the other singa tha twe dont perc ie liek singlafrom the heart kdiney and other organd thei si cisceral sensory then ther i smotor nerouv sysmte tha tintiates and trmaited fromiotn o fhte CNs to effectorsomat motot
