He aha ka vestigiality?

No ka hapa nui, lawelawe kāu mau lālā a me nā lālā i kahi kumu, no laila ke kū nei i ke kumu no ka lilo ʻana o kekahi o kēia mau mea ke hoʻopilikia i ka hana maʻamau o kou kino, i kēlā me kēia lā.

Ma ka ʻaoʻao ʻē aʻe, ʻike nui ʻia hiki ke hemo kekahi mau lālā, e like me ka hoʻopili, me ka ʻole o ka hopena. ʻO ia no ka mea, ʻoiai he nui nā ʻano o ke kino i kūpono i kahi ala maopopo, ua nalowale kekahi mau kūkulu ʻana i kā lākou hana mua i ka holo ʻana o ka manawa.

ʻO ka vestigiality kanaka e pili ana i nā ʻāpana o ke kino e like me ka mea ʻaʻole lawelawe i kahi kumu. Manaʻoʻiʻo ʻia ko mākou mau kūpuna, i kekahi manawa, pono i kēia mau ʻāpana o ke kino. Eia nō naʻe, ua lilo ka hapa nui o kā lākou mau hanana i ka hapa nui o kā lākou hana mua, a lilo maoli i kapa ʻia kekahi mau inoa ʻo "nā ʻōpala."

Manaʻo kekahi he hiʻohiʻona kēia mau hale i ka evolution o ke kanaka. Manaʻo kekahi he kumu ko nā mea i kapa ʻia ʻo nā vestigial, ʻoiai ʻaʻole maopopo kēia mau kumu.

E hoʻohālikelike, ua manaʻo kekahi mau kauka a me nā ʻepekema he tonsiliality kahi kanaka. Akā ua ʻike ka ʻepekema ma hope he kuleana ko nā tonsil i ka pale ʻana, e kōkua ana i ke kino e hakakā i nā maʻi.

ʻO kekahi mau laʻana o ka vestigiality:

• niho naauao
• pakui
• huluhulu kino

Loaʻa i kekahi poʻe kahi huelo vestigial. ʻOiai he mea, ʻo nā kānaka me nā huelo i ʻike ʻia i nā moʻokalaleo i loko o ka mōʻaukala.

He aha ke kumu o ka huelo vestigial?

ʻOiai he kākaʻikahi loa nā huelo i ke kanaka, loaʻa nā hanana huelo kūlohelohe i ka embryo kanaka. Hoʻolālā kēia mau huelo a puni ka, a loaʻa ma kahi o 10 a 12 vertebrae.

ʻAʻole hānau ʻia ka hapanui o ka poʻe me kahi huelo no ka mea e nalowale a ʻaʻapo paha ka hanana i ke kino i ka wā o ka ulu ʻana o ka fetal, e hana ana i ka tailbone a i ʻole coccyx. ʻO ka iwi huelo he iwi triangular aia ma ka ʻaoʻao haʻahaʻa o ke kuamoʻo ma lalo o ka sacum.

ʻO ka nalowale ʻana o ka huelo i loko o ka embryo kahi i kahi o ka pule ʻewalu o ka hānau ʻana.

ʻOiai nalowale kahi huelo vestigial no ka hapa nui o ka poʻe, i kekahi manawa noho ka huelo ma muli o kahi kīnā i ka wā o ka ulu ulu. I ka hihia o kahi huelo vestigial "ʻoiaʻiʻo", ʻaʻole ʻike ʻia ke kumu kūpono o kēia kīnā.

He mea nui e hoʻomaopopo ua hānau ʻia kekahi poʻe me kahi pseudotail, ʻaʻole like ia me ka "tail" tailigial tail. Hiki i kahi pseudotail ke nānā aku e like me ka huelo vestigial, akā hana pinepine ʻia e kahi coccyx elongated a i hoʻopili ʻia i ka spina bifida.

I loko o nā keiki hānau hou me kahi pseudotail hānau, ua hōʻike ʻo MRI i ka hōʻike o ka spina bifida - kahi kīnā hānau kahi e hana pono ʻole ai ke kuamoʻo a me ka iwi kuamoʻo.

He aha ka huelo vestigial i hana ai?

Ke hoʻopili ʻole kahi huelo vestigial me ka coccyx a noho mau ma hope o ka hānau ʻana, he aha ka mea i koe o ka ʻili i loaʻa ʻole nā ​​iwi. ʻOiai nele ka iwi i ka huelo, loaʻa nā aʻa i loko, ke koko, nā aʻa adipose, nā mea hoʻopili, a me nā mākala.

ʻO ka mea e mahalo ai, hiki ke hoʻoneʻe ʻia ka huelo (i kekahi poʻe) e like me nā ʻāpana ʻē aʻe o ke kino, ʻoiai ʻaʻole ia e hāʻawi i kahi hana kūpono. No laila, ʻaʻole hoʻohana ʻia ka huelo e lālau a hoʻopaʻa i nā mea.

Pehea e mālama ʻia ai kahi huelo vestigial?

ʻO ka hoʻoholo e ʻimi i ka lāʻau no ka huelo vestigial kaukaʻi i ka nui o ka abnormalities. Liʻiliʻi kekahi mau huelo a ʻaʻole pilikia. Akā hiki i nā huelo lōʻihi ke hoʻopili i ka noho. Hiki i kēia mau huelo ke 5 ʻīniha.

No ka mea ʻaʻohe iwi o nā huelo vestigial, ʻaʻohe o kēia mau huelo e hōʻeha a hōʻehaʻeha paha. Hiki paha ke ʻeha me kahi pseudotail no ka mea pili lākou i ka iwi a i ʻole ka vertebrae.

Pono nā pēpē i hānau ʻia me ka huelo vestigial e hana i kahi hoʻokolohua kiʻi e like me MRI a i ʻole ultrasound. Pono kēia e hoʻokaʻawale i ka huelo a hōʻoia ʻaʻole i pili me kahi ʻano olakino e like me spina bifida.

ʻO ke ʻoki lāʻau ka lāʻau no ka huelo vestigial. Ma muli o kahi huelo vestigial "ʻoiaʻiʻo" i haku ʻia me ka adipose a me nāʻiʻo muscular, hiki i nā kauka ke lawe koke i kēia ʻano huelo me kahi excision maʻalahi. ʻAʻole hana kēia kaʻina hana i nā hopena ʻaoʻao koena.

E noʻonoʻo ʻaʻole pono ka hemo ʻana i ka lāʻau, ʻoiai makemake kekahi mau mākua i ke ʻoki no nā kumu cosmetic. Koho paha lākou e hemo ka hanana mai kā lākou keiki ma hope koke o ka hānau ʻana. Ke liʻiliʻi ka huelo vestigial a like me ka nub, haʻalele paha nā mākua i ke ʻoki kino.

He aha ka nānā no ka huelo vestigial?

Inā loaʻa iā ʻoe a kāu keiki paha kahi huelo vestigial, hiki iā ʻoe ke wehe iā ia ma o kahi kaʻina maʻalahi, a i ʻole mālama i ka huelo inā liʻiliʻi ia.

ʻO ka noho ʻana me ka huelo vestigial ʻaʻole ia e alakaʻi i nā pilikia a i ʻole ke kumu o nā pilikia lōʻihi. Akā inā koho ʻoe e hemo i ka huelo, maikaʻi ka wānana a nalowale ke ʻano ʻaʻohe hopena maikaʻi ʻole.

ʻO ka hoʻoholo e hemo a mālama nui paha i ka hopena o ka huelo i kou ola. Inā he mea hoʻonāukiuki iā ʻoe a pale paha i nā pili pili, hiki i ka hoʻolei ʻana i ke ʻano ke hoʻomaikaʻi i ka maikaʻi o kou ola a hoʻonui i kou hilinaʻi iā ʻoe iho.
