Isikhutha

I scrotum noma scrotal sac kuyinto yokwakheka besilisa isakhiwo zokuzala sise kumila umthondo ukuthi siqukethe okwesikhashana sac-dual-chambered zesikhumba bushelelezi kwemisipha. Itholakala ezilwaneni eziningi ezincelisayo zesilisa ezisemhlabeni.I-scrotum iqukethe i- spermatic fascia yangaphandle, ama- testes, i- epididymis, ne ductus deferens.Kungukuhlukaniswa kwe- perineum futhi kuthwala izicubu ezithile zesisu emgodini wayo kufaka phakathi umthambo wamasende, umthambo wamasende, ne-pampiniform plexus.I- perineal raphe iyisigaxa esincane, esime mpo, esikhuphuke kancane sesikhumba esingaphansi lapho okutholakala khona i- scrotal septum.Kubonakala njengolayini omncane we-longitudinal ogijima ngaphambili uye emuva phezu kwesikhafu sonke.Kubantu nakwezinye izilwane ezincelisayo i-scrotum imbozwa izinwele zasesidlangalaleni ngesikhathi sokuthomba .I-scrotum imvamisa iqine ngesikhathi sokumiswa kwe-penile nalapho ivezwa emazingeni okushisa abandayo.I-testis eyodwa ngokuvamile iphansi kunenye ukugwema ukucindezelwa uma kwenzeka kuba nomthelela. ^[1]

I-scrotum i-biologically homologous kuya kuma- labia majora kwabesifazane.Yize sikhona ezilwaneni eziningi ezincelisayo, i-scrotum sangaphandle asikho ezilwaneni ezincelisayo zasolwandle ezihlanjululwe, njengemikhomo nezimpawu,kanye nakwezinye izizukulwane zezilwane ezincelisayo zomhlaba, njengama- afrotherians, ama- xenarthrans, nemindeni eminingi yamalulwane, amagundane, kanye nezinambuzane.^[2]

Iscrotum

Umdwebo wesikhwama. Ngakwesobunxele kuvulwe umgodi we- tunica vaginalis; Ngakwesokudla kuphela izingqimba ezingaphezulu kwemisipha yeCremaster ezisusiwe.

Isikhumba nezindlala

Isikhumba esisesikhotheni sesikhumba sinombala ophakeme kakhulu uma siqhathaniswa nawo wonke umzimba. I-septum ulwelwesi lwezicubu ezihlanganayo oluhlukanisa i-scrotum zibe izimbotshana ezimbili.

Uhlelo lweLymphatic

I-scrotum lymph idonsela ekuqaleni kuma-lymph node angenhla, lokhu kudlulela kuma-lymph node ajulile.Ama-lymph node ajulile angenela ku-iliac ejwayelekile ekugcineni ekhipha i-lymph ku-cisterna chyli.

I-Asymmetry

I-testis eyodwa ngokuvamile iphansi kunenye, okukholelwa ukuthi isebenza ukugwema ukucindezelwa uma kwenzeka kuba nomthelela; kubantu, ama-testis angakwesokunxele ngokuvamile aphansi kunesokudla.Umbono ohlukile ngothi i-testis descent asymmetry yavela ukuze kupholise amasende ngempumelelo.

Isakhiwo sangaphakathi

Intuthuko

Izigaba ekukhuleni kwesitho sangasese sangaphandle sowesilisa.

Umsebenzi

Isikhwama somuntu esimweni esikhululekile (kwesobunxele) nesimo esishubile (kwesokudla)

Isikhutha silawula ukushisa kwamasende futhi sikugcine kuma-35 degrees Celsius (95 degrees Fahrenheit), okusho ukuthi ama-degree amabili noma amathathu ngaphansi kwezinga lokushisa komzimba elingu-37 degrees Celsius (98.6 degrees Fahrenheit).Amazinga okushisa aphakeme athinta i- spermatogenesisUkulawulwa kwamazinga okushisa kufezwa yimisipha ebushelelezi yesikhotha esihambisa amasende noma asondele eduze noma kude nesisu esixhomeke emazingeni okushisa ambient.Lokhu kufezwa umsipha we-cremaster esiswini kanye ne- dartos fascia (izicubu zemisipha ngaphansi kwesikhumba).

Ukubaluleka komtholampilo

Ucwaningo luveze ukuthi ukusetshenziswa kwekhompyutha ephathekayo ebekwe ethangeni kungathinta kabi ukukhiqizwa kwesidoda. ^[3]

Izifo nemibandela

I-scrotum nokuqukethwe kwayo kungahlakulela izifo noma kungene ukulimala.
