Tshwj xeeb siab sensors hu ua baroreceptors (los yog venoatrial stretch receptors ) nyob nyob rau hauv txoj cai atrium ntawm lub plawv pom nce hauv ntim thiab siab ntshav rov los rau hauv plawv. Cov no receptors xa cov ntaub ntawv raws tus kab mob vagus (lub paj hlwb thib 10) mus rau lub hauv paus paj hlwb.
Tsuas yog li ntawd, qhov twg yog qhov chaw txais khoom nyob hauv daim tawv nqaij?
Tawv nqaij receptors Merkel discs thiab Meissner corpuscles yog nyob ze ntawm qhov chaw ntawm tawv nqaij ntawm dermal – epidermal kev sib tshuam, muaj kev nkag siab zoo rau qhov chaw ntsug siab , thiab pab txhawb kev nkag siab ntawm lub teeb kov.
Qhov thib ob, hom kev txais neeg saib xyuas ntshav siab li cas thiab lawv nyob qhov twg? Baroreceptors (los yog archaically, pressoreceptors) yog sensors nyob hauv carotid sinus (ntawm qhov sib txawv ntawm sab nrauv thiab sab hauv carotids) thiab hauv aortic koov. Lawv sense cov ntshav siab thiab xa cov ntaub ntawv mus rau lub hlwb, yog li qhov tsim nyog ntshav siab tuaj yeem tswj tau.
Khaws qhov no saib, qhov twg pom cov neeg txais tos?
Kov cov neeg txais yog subtype ntawm kev hnov qab neuron uas yog nyob nyob rau ntawm daim tawv nqaij thiab muaj qhov tshwj xeeb kawg uas teb rau kev txhawb nqa lub tshuab. Raws li ib feem ntawm somatosensory system, kov cov receptors yog li ntawd xa cov ntaub ntawv hais txog kev cuam tshuam txog kev cuam tshuam rau lub hauv paus paj hlwb.
Cov neeg txais lub siab hu li cas?
Lamellar corpuscle Lamellar corpuscles, lossis Pacinian corpuscles, yog siab receptors nyob hauv daim tawv nqaij thiab tseem muaj ntau yam kabmob sab hauv. Txhua tus tau txuas nrog lub paj hlwb. Vim tias nws qhov loj me me, ib leeg lamellar corpuscle tuaj yeem raug cais thiab nws cov khoom tau kawm.
