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]

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

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-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.

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).

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

I-scrotum nokuqukethwe kwayo kungahlakulela izifo noma kungene ukulimala.

• Ukufakwa okuningana, uhlobo lwesikhashana lokuguqulwa komzimba
• Isitho socansi
• Ukuhlukaniswa kwe-lymph node ye-Retroperitoneal
• Ukuzihlola kwamasende
