I-Cruralgia noma i-crural neuralgia ubuhlungu obulandela inkambo ye-crural nerve (manje ebizwa ngokuthi i-femoral nerve).

Le nerve ivela phansi komgogodla (noma umgogodla) kusukela emhlanganweni wezimpande zezinzwa eziphuma emthonjeni womgogodla, noma intambo yomgogodla ngokusho kwe-nomenclature entsha. Lo mnkantsha uyintambo engaba ngu-50 cm ubude enweba ubuchopho futhi ivikeleke ngaphakathi komgogodla owuvikela emathanjeni omgogodla.

Sekukonke, amapheya angama-31 ezinzwa aphuma kwesokudla nakwesobunxele somgogodla womgogodla: noma, ukusuka phezulu kuya phansi, 8 entanyeni (izimpande zomlomo wesibeletho), 12 ukusuka emhlane ongaphezulu (izimpande zethoracic), 5 ukusuka emhlane ophansi ( izimpande ze-lumbar), 5 ezingeni le-sacrum kanye ne-1 ezingeni le-coccyx.

I-crural nerve, njengazo zonke izinzwa zomgogodla, i-nerve enezinzwa kanye ne-motor: ingena ngaphakathi kwethanga nomlenze futhi ivumela ukugoba kwethanga esiqwini, ukunwetshwa kwedolo kanye nokuqoqwa kwezinto ezibucayi. ulwazi oluvela kulesi sifunda (kushisa, ukubanda, ubuhlungu, ukuthintana, ingcindezi, njll.)
