Izicubu ezinamafutha angaphantsi: isakhiwo kunye nomsebenzi

Amanqatha angaphantsi kwamanzi atholakala emva kwangoko-dermis layer - isikhumba sakhe. Ezi zicubu ezikwimimandla ephezulu zigcwele i- collagen fibers. Bakha kwifom ye-intanethi ye-adipose tissue extensive network, equlethwe ngamanzi amakhulu. Ezi zakhiwo, njengomthetho, zizaliswe ngamathambo anamafutha.

Ziziphi izicubu ezinamafutha angaphantsi?

Ngaphantsi kobuncwane besikhumba se-fatty kudala into efana nelayini elithambileyo, elinikezelayo kuphela ukunyanzelisa, kodwa kunye nokutsalwa kwe-thermal. Ukongezelela, iingubo zenza ezinye, imisebenzi ebalulekileyo. Nangona kunjalo, ezinye zazo zinokulimaza.

Sekude kusekwa ukuba izicubu ezinamafutha angaphantsi kwenziwe ngumhlobo othize weethambo ezixhumeneyo. Esi sisona saso sigxina. Kuyaziwa ukuba amanqatha emzimbeni womntu angaba nomlinganiselo omkhulu. Esi sibonelelo maxa wambi sifinyelela amashumi eekhigram.

Ngangakanani amanqatha omzimba?

Kubalulekile ukuba uqaphele ukuba i-fat fatcutaneous isatshatyalaliswa ngokungafanelanga kuwo wonke umzimba. Kubasetyhini, ngokuqhelekileyo kufakwe kwiimfumba kunye neenyawo, kunye nenani elincinci kwisigu esifubeni. Kwamadoda, amanqatha aqokelela kwenye indawo. Oku kufuneka kufake indawo yesisu nesifuba. Kwafunyaniswa ukuba, ngokumalunga nobukhulu bomzimba, ubunzima beethambo ezinamafutha: kubasetyhini-25%, kunye namadoda-15%.

Ubuninzi bobunzima beethambo bubonakala kwisisu, emacaleni nasesifuba. Eli nani kule ndawo linokufikelela kuma-centimitha angama-5. I-subtlest yi-tissue e-subcutaneous fatty kwi-genital area kunye neentloko zeentloko.

Umsebenzi wamandla

Yimiphi imisebenzi yamathambo angaphantsi? Okokuqala, kubalulekile ukuphawula amandla. Le yenye yeenjongo eziphambili zeoli. Kungenxa yalo msebenzi ukuba ezi zicubu ziyimfuneko.

Ngexesha lokuzila ukudla, umzimba kufuneka ufumane amandla. Ndingafumana phi na ukuba akukho ukutya? I-fat is substrate yamandla enamandla. Unako ukunika umzimba amandla okusebenza ngokuqhelekileyo. Kubalulekile ukuba uqaphele ukuba igramu e-1 yamathambo angaphantsi anganika umntu 9 kcal. Le mali yamandla yanele ukunqoba iimitha ezili-mitha zeemitha ngokukhawuleza ngokukhawuleza.

Ukutyalwa kwamanzi

Iisuncu ezinamafutha, ihamba ngokugqithiseleyo ubushushu obuvela emzimbeni womntu. Oku kubaluleke kakhulu kumzimba. Amanqatha angaphantsi kwelolu hlobo enza umsebenzi wokushisa ukushisa. Amathuba anjalo omzimba wethu ngokwenene ekunciphiseni ubushushu.

Nangona kunjalo, iingcali ziye zaqinisekisa ukuba imisebenzi efana neenqatha ezincinci zinokuchaphazeleka. Inani elikhulu lamanqatha lingonakalisa nje ukubonakala, kodwa kubangele ukuphuhliswa kwezifo ezinjengokutshatyalaliswa kwe-osteoarthritis, uxinzelelo lwegazi, isifo sikashukela, i-atherosclerosis.

Umsebenzi okhuselekileyo we-fat fatcut

Amanqatha angaphantsi komzimba aphuhliswa kuwo wonke umntu onempilo. Ezi zicubu zibaluleke kakhulu kumzimba wethu. Emva koko, yenza imisebenzi emininzi, phakathi kwabo kukhusela. I-Fat ayikho kuphela phantsi kobunqamlezo be-dermis, kodwa iphinda ivule izitho zangaphakathi. Kule meko, iwakhusela kwiintshutshiso kwaye iyancipha ukutshitshiswa, kwaye ikhusela ekukhuseleni kwiqondo lokushisa okwaneleyo. Ukugqithisa ubuninzi bomzimba we-adipose tissue, amandla amaninzi athatha kwizinto ezifudumeleyo.

Ukongezelela, izicubu ezinamafutha zinika ukuhamba kwesikhumba. Oku kukuvumela ukuba ugxininise okanye uwatwebise. Oku kukwazi ukukhusela izicubu ezivela kwimimandla kunye neminye imionakalo.

Ukuqokelela

Lo ngumnye umsebenzi owenziwa ngamanqatha angaphantsi. Nangona kunjalo, kwezinye iimeko, olu buchule lweethambo lungalimaza umzimba. I-accumulates not fat fat, kodwa kunye nezinto ezinokuqhekeza kalula kuyo, umzekelo, i-hormone ye-estrogen, kwakunye namavithamini amaqela E, D kunye no-A. Ngakolunye uhlangothi, akubi. Nangona kunjalo, kumadoda anesiseko esanele ngokwaneleyo samathambo angaphantsi, ukuveliswa kwe testosterone yabo kuncitshiswa kakhulu. Kodwa le hormone ibalulekile kwimpilo yabo.

Umsebenzi wokuvelisa iHormone

Iingcali zenzululwazi ziye zafakazela ukuba amanqatha angaphantsi awanako kuphela ukuqokelela i-estrogens ngokwayo, kodwa ivelise ngokuzimela. Ubuninzi beetekisi, ama-hormone angaphezulu awenzayo. Ngenxa yoko, isangqa esilungileyo sidalwa. Amadoda asengozini. Emva koko, i-estrogens iyakunqanda imveliso ye-androgens. Oko ke, kukhokelela ekubonakaleni kweso sizwe, esichazwa ngokunciphisa ukuveliswa kwee-hormone zesondo, kuba umsebenzi weentlobano zesini udla kakhulu.

Ukongezelela, kwiiseli ezinamafutha kukho i-aromatase - i-enzyme ekhethekileyo ethatha inxaxheba kwiinkqubo zokwenziwa kwe-estrogens. Iisishubhu ezisebenzayo kakhulu kule nkalo zifumaneka ematyeni nasemathangeni. Kubalulekile ukuba uqaphele ukuba amanqatha angaphantsi kwamandla akwazi ukuvelisa i-leptin. Le nkunkuma i-hormone ekhethekileyo ejongene nomvakalelo we-saturation. Ngoncedo lwe-leptin, umzimba unako ukulawula umlinganiselo weoli ephantsi kwesikhumba.

Iintlobo kunye nesakhiwo seethambo ezinamafutha

Isakhiwo samathambo angaphantsi kancinci. Emzimbeni womntu, kukho iintlobo ezimbini zezi zicubu: ezimdaka kunye ezimhlophe. Ezi ntlobo zokugqibela zifumaneka kwizinto ezininzi. Ukuba ucinga ingcezu yamanqwanqwa angaphantsi kwinqanaba le-microscope, ngoko ukwazi ukubona ama-loble, ngokucacileyo ukwahlukana. Phakathi kwabo kukho i-jumpers. Yisisombululo esisebenzayo.

Ukongeza, unokubona iimbilini ze-nerve kwaye, impela, imithwalo yegazi. Icandelo eliphambili lezakhi eziphathekayo li-adipocyte. Le neseli enesimo esincinci okanye esilungileyo. Ububanzi, buya kufinyelela kuma-micromons angama-50-200. Kwi-cytoplasm, iqulethe i-lipids. Ukongeza kwezi zinto, iseli iqukethe amaprotheni namanzi. I-Adipocytes (iiseli ezinamafutha) nazo ziqukethe i-lipids. Isixa semilinganiselo yesistim esivela kwisisindo sisisitye se-3 ukuya ku-6%, kunye namanzi-angabi ngaphezu kwama-30%. Phakathi kwezinye izinto, i-hypodermis inomlinganiselo omkhulu wemikhumbi ye-lymphatic.

Amanqatha angaphantsi kwezona zinto zibalulekileyo zomzimba womntu, enze imisebenzi eninzi kwaye inemfuneko.
