Qhov sib txawv tseem ceeb ntawm dermatome thiab cutaneous innervation yog qhov dermatome yog thaj tsam ntawm daim tawv nqaij uas yog innervated los ntawm ib leeg txha caj qaum. Meanwhile, cutaneous innervation yog thaj tsam ntawm daim tawv nqaij innervated los ntawm ib tug tshwj xeeb cutaneous paj.
Daim tawv nqaij yog lub cev loj tshaj plaws uas peb muaj. Nws yog sab nraud ntawm peb lub cev. Tsis tas li ntawd, nws ua ntau yam haujlwm. Nws muab kev tiv thaiv kab mob thiab lwm yam tshuaj lom. Tsis tas li ntawd, nws pab tswj peb lub cev kub thiab ua kom yooj yim rau kev kov, kub thiab txias. Tsis tas li ntawd, txhawm rau muab kev hnov qab thiab paj hlwb rau ntawm daim tawv nqaij, muaj cov hlab ntsha sib txawv hauv daim tawv nqaij. Lawv raug hu ua cutaneous paj. Cutaneous innervation yog hais txog thaj tsam ntawm daim tawv nqaij uas tau muab los ntawm cov hlab ntsha tshwj xeeb. Lub dermatome yog ib yam ntawm cutaneous innervation, tab sis nws tshwj xeeb yog hais txog ib cheeb tsam uas tau muab los ntawm ib leeg txha caj qaum.
Dermatome yog dab tsi?
A dermatome yog ib thaj tsam ntawm daim tawv nqaij uas tshwj xeeb muab los ntawm ib leeg txha caj qaum. Nyob rau hauv ib lub dermatome, peb tuaj yeem nrhiav pom cov neurons uas tshwm sim los ntawm tus txha caj qaum ganglion. Cov hlab ntsha no feem ntau yog afferent paj fibers los ntawm ib leeg dorsal cag ntawm tus txha caj qaum. Txawm li cas los xij, qee zaum, dermatome yuav tsis tshua meej thaum lub paj hlwb ua haujlwm rau ntau lub paj hlwb. Tab sis, feem ntau ntawm cov sij hawm, dermatome yog heev tshwj xeeb. Peb lub cev muaj 30 dermatomes. Lawv raug suav raws li tus txha caj qaum uas lawv sib raug rau.
Daim duab 01: Dermatomes
Dermatomes tshwm sim raws li pawg ntawm cov discs uas tsim tib neeg. Txhua lub dermatome muaj ib qho tshwj xeeb ntawm cov hlab ntsha hlwb. Yog li, txhua tus txha caj qaum relays hnov los ntawm ib cheeb tsam ntawm daim tawv nqaij mus rau lub hlwb. Qhov tseem ceeb tshaj plaws, dermatome innervation yog qhov tshwj xeeb rau txhua tus neeg, zoo ib yam li tus ntiv tes. Cov tsos mob ntawm tus kab mob tshwm sim nyob rau hauv dermatome qhia hais tias pathology muaj feem xyuam rau hauv lub paj hlwb. Yog li ntawd, dermatomes yog qhov tseem ceeb hauv kev txiav txim siab seb qhov kev hnov tsw ntawm lub cev puas sib haum rau ib ntu ntawm tus txha caj qaum. Ntxiv mus, dermatomes yuav pab tau kom paub qhov muaj thiab qhov twg ntawm tus txha caj qaum.
Cutaneous Innervation yog dab tsi?
Cutaneous innervation yog hais txog thaj tsam ntawm daim tawv nqaij uas muaj cov hlab ntsha los ntawm cov hlab ntsha tshwj xeeb. Yog li ntawd, cov hlab ntsha ntawm daim tawv nqaij yog lub luag haujlwm tseem ceeb rau kev nkag siab ntawm daim tawv nqaij.
Daim duab 02: Cutaneous Innervation
Cov hlab ntsha ntawm lub cev tuaj yeem ua rau lub siab xav thiab tsis muaj kev xav (sensory) fibers. Muaj ntau cov hlab ntsha sib txawv nyob hauv peb lub cev.
Dab tsi yog qhov zoo sib xws ntawm Dermatome thiab Cutaneous Innervation?
Ua kom paub txog cov kab mob dermatomes thiab cutaneous innervations yuav pab cov kws kho mob kom nkag siab zoo dua cov tsos mob ntawm cov hlab ntsha
Qhov txawv ntawm Dermatome thiab Cutaneous Innervation yog dab tsi?
A dermatome yog ib thaj tsam ntawm daim tawv nqaij uas tau muab los ntawm ib leeg txha caj qaum. Meanwhile, cutaneous innervation yog hais txog ib cheeb tsam ntawm daim tawv nqaij innervated los ntawm ib tug tshwj xeeb cutaneous paj. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm dermatome thiab cutaneous innervation.
Summary – Dermatome vs Cutaneous Innervation
Cutaneous nerves yog cov hlab ntsha uas muab cov hlab ntsha rau ntawm daim tawv nqaij. Muaj ntau cov hlab ntsha cutaneous hauv peb cov tawv nqaij. Cutaneous innervation yog hais txog thaj tsam ntawm daim tawv nqaij muab los ntawm cov hlab ntsha tshwj xeeb. Lub caij no, dermatome yog ib qho chaw ntawm daim tawv nqaij uas tau txais cov paj hlwb los ntawm cov hlab ntsha qaum. Nws yog ib hom ntawm cutaneous innervation. Tab sis, nws yog qhov tseeb dua vim tias nws tau muab los ntawm fibers los ntawm ib leeg paj hlwb. Yog li, qhov no qhia txog qhov sib txawv ntawm dermatome thiab cutaneous innervation.
