Pudendal nerv perineumning asosiy nervidir[1]:274.U ikkala jinsning, yaʼni erkak va ayol tashqi jinsiy aʼzolaridan va anus va perineum atrofidagi teridan sezuvchanlikni, shuningdek, turli xil tos mushaklarini, shu jumladan erkak yoki ayolning tashqi siydik yoʻli sfinkteri va tashqi anal sfinkterini harakat bilan taʼminlaydi. Agar shikastlangan boʻlsa, koʻpincha tugʻruq paytida, lezyonlar hissiy yoʻqotish yoki najasni ushlab turishga olib kelishi mumkin. Nerv, anestetik protseduraning bir qismi sifatida vaqtincha bloklanishi mumkin.
Pudendal asabni olib yuradigan pudendal kanal, shuningdek, 1836-yilda ushbu kanalni hujjatlashtirgan irlandiyalik anatomist Benjamin Alkok nomi bilan atalgan „Alkok kanali“ atamasi bilan ham tanilgan.
Anatomik yadrosi[tahrir | manbasini tahrirlash]
Nerv sakral pleksusning asosiy tarmogʻidir[2] :950,orqa miyaning sakral mintaqasidagi Onuf yadrosidan kelib chiqqan tolalar bilan[3].
Variatsiya[tahrir | manbasini tahrirlash]
Pudendal nervga doir kasalliklar kelib chiqishiga koʻra farq qilishi mumkin. Masalan, pudendal asab aslida siyatik asabdan kelib chiqishi mumkin[4].Binobarin, siyatik asabning shikastlanishi pudendal asabga ham taʼsir qilishi mumkin. Baʼzan birinchi sakral asabning dorsal rami pudendal asabga qoʻshiladi va hatto kamdan-kam hollarda S5[3].
Funksiyasi[tahrir | manbasini tahrirlash]
Pudendal nerv ham motor, ham sensor funktsiyalarga ega. U parasempatik tolalarni olib yurmaydi, balki simpatik tolalarni olib yuradi[5]:1738.
