Ilungu wetatshi. Yintoni na?

lungu lafaka yi kwesongezelelo se receptors ezithile, apho ibekwe izihlunu, imisipha namalungu, ulusu kunye isifo obuni, ulwimi, imilebe. Lafaka izitho zabantu ukuqonda ngamnye zoomatshini. Ngokomzekelo, sisenokuvakalelwa ezinye ukuzibaxa uxinzelelo, ngaphandle kwebala, iintlungu kunye nobushushu. Ngokumalunga afferent innervation ulusu, loo ikhutshwa phandle ezikhethekileyo luvo, nto leyo kuza bevela luvo ganglia spinal. receptors lafaka ise kakhulu eluswini, luvo neuron oluvo kwakheka. Ngokubanzi, njengokuba sele kukhankanyiwe, receptors ulusu bayakwazi ukuqonda kuphela iikhemikhali kunye zizinto mechanical, kodwa zombane kunye neqondo lobushushu.

Ezenza, njengokuba ilungu wetatshi, kunokuba ubushushu okanye ephathekayo, kodwa buhlungu nje kuphela. Ngokutsho physiologists, ngamnye kubo wenza nje isixhobo wakuqonda. kwalapho zahlulwe iintlobo ezimbini: non-free and free. umahluko sabo phambi kwi lombhobho yezihlunu yesibini kunye neeseli gly kwindawo yokuqala.

Ilungu wetatshi - oko kukuthi, ngaphezu kwabo bonke, kwalapho free. Kulusu yabantu imali omkhulu. Abaninzi kubo intshebe. Kulusu yabantu, nto leyo ligutyungelwe iinwele, sichaze nje kuphela kwalapho simahla, kodwa mehanoretsepotry ezijongwa ezizodwa kakhulu. Umzekelo, eluswini iminwe kwi izandla kweentende zeenyawo zikwindawo Meissner corpuscles, Krause kunye nebhalbhu eziphezu isifo komlomo, neengono zithi, zokuzala, ngokubonelela nto kuthiwa ummandla ubuntununtunu banda. Njengoko ngokuba kwebala le nkqubo, luquka zokuluka kwezihlunu okanye proprioceptors izihlunu, ifascia, imisipha namalungu. Omnye wemiba zonke iinkalo ephathekayo kwabantu imvakalelo wetatshi ingqalelo imizimba ngezifo ngokwabo, yaye ingakumbi excitation zabo zexeshana kunye lomhlaba.

Ukungena Ebubanzini sangaphandle ezininzi kwalapho free. Bebona nokushukunyiswa iintlungu. Le nkqubo ibizwa ngokuba nociception. Le touch kakhulu gentle zibonwa ikakhulu kwalapho, nto leyo zoba ngeenxa kwiingcambu iinwele. Ukongeza kukho abaninzi sangaphandle leeseli Merkel abanenxaxheba ngokuthe ngqo kwimbono na ngaphandle kwebala. Ukongeza, ukuba nokulungelelanisa ezo molekyuli neuronal, neurofilaments kunye namanye amagosa amakishayo ezininzi ngqo kwezi seli zemithambo-luvo. Wadibana-enkephalin ivuselele phantse zonke iimpendulo omzimba emzimbeni womntu. Kwaye oku nangona into yenziweyo iiseli efanayo Merkel. Kwelinye iziko kwebala lo corpuscles Meissner, leyo sele ikhankanyiwe apha ngasentla. Bona ikakhulu kule nwebu papillary ye eluswini zokuzala, iminwe, Neenkophe kunye nemilebe. ububanzi yabo ayikho microns ngaphezulu kwe-100. Ukongezelela, nganye kwezi seli ingqongwe ngaphandle nokuqina kwezihlunu capsule okhethekileyo. Le nto ndiyibhalayo iiseli glial, nto leyo zenza thickenings yesiphelo malunga kwimicu ngamnye luvo ezibuthathaka ngaphakathi iselwa.

Loo umzimba wetatshi njengoko receptor xi lamellar Vater-Pacini corpuscle. Inani elikhulu kwezi leseli subcutis lilele kummandla pudendal, iinzwane, nezibilini philisi, iindonga lwesinye. Netoti ithole elinye lingaphantsi ndlela. Ngokubanzi ke luphawulwa phambi embilwini kunye nemvulophu engaphandle, ngoxa embindini isebe lokuqala Kudlula ifayibha luvo, nto leyo ethe kakhulu.

Ubuchopho bomntu lifumana esikhulu isixa ulwazi malunga ihlabathi. Kulo mzekelo, kubaluleke kakhulu kwinkqubo kwimbono yehlabathi ngamnye kuthi nje ngaphandle kwebala. Sense zomzimba - receptors oyivileyo ibekwe kulo kumphezulu umzimba. Ngenxa yale siziva ubushushu, iintlungu, kwebala kunye nangaphezulu.
