I-Linea nigra ligama lesiLatini elithetha "umgca omnyama," kwaye lo ngumgca omnyama othe nkqo obonakala eluswini lwesisu sakho ngexesha lokukhulelwa. Lo mgca udla ngokususuka kwiqhosha lesisu sakho uye kwisisu sakho esisezantsi, nangona kwezinye oomama unokunyuka udlulele nasezifubeni zabo.

Makhe sicinge ngale nto kunye. Ngaphambi kokuba ukhulelwe, lo mgca ubusoloko usesiswini sakho, kodwa ububizwa ngokuthi yi-Linea Alba, okuthetha ukuthi "umgca omhlophe". Ngelo xesha ungaphambi kokuba ukhulelwe, ubuxhaphake kakhulu okanye ukhanya kangangokuba amehlo ethu awakwazi nokuwubona. Kodwa xa ukhulelwe, iihomoni zakho ziyasuka zikhuthaze iiseli zesisu sakho ukuba zivelise umbala omninzi, ngoko ke lo mgca uba mnyama uze ubonakale ngokuphandle. Pretty surprising, right?

Ngexesha lokukhulelwa kwakho, lo mgca uqala ukuba mnyama kancinci kancinci njengoko iiveki zihamba. Kwabasetyhini abaninzi, lo mgca uqala ukuvela ngokucacileyo kwikota yesibini yokukhulelwa, malunga neeveki ezingama-20 zokukhulelwa.
Makhe sizibuze: Ingaba uqaphele ukuba ezinye iindawo nazo ziba mnyama ngeli xesha? Ewe, kanye njengamabala amancinci ebusweni (awabizwa ngokuba yi-melasma okanye "isigqubuthelo sokukhulelwa") kunye nokuba mnyama kweetoni zakho zamehlo okanye ngaphantsi, i-linea nigra yinxalenye nje yotshintsho oluqhelekileyo lwezinto eziphilayo emzimbeni wakho.

Ngoko ke, xa imveliso ye-melanin isanda ngenxa yempembelelo yehomoni yokukhulelwa, i-Linea Nigra yabo iba mnyama kakhulu kwaye ibonakale kakhulu. Kubantu abanolusu olukhanyayo, isenokungabonakali kangako, okanye ibe mdaka kancinci. Have you ever wondered why some mothers have it darker than others?
