Iyo gland pituitary ndiyo inonyanya kukosha gland. Inowanikwa panheyo yeuropi. Kubva pamigumisiro yekunze kwezvinhu, inodzivirirwa kubva kumativi ose nemapfupa. Plandish gland ine mamwe mabasa, kushandiswa kwakakodzera kwaiko kunonyanya kukosha kwekushanda kwemuviri.
Idzi nhatu nhatu dzinokosha dze gland pituitary
Zvechokwadi, ivo vakakura zvikuru. Asi nokuda kwechinhu chikuru chinogamuchirwa kutora mabasa matatu chete:
- Iyo plandishi gland inokonzerwa nekudzidzira kutarisa pamusoro pezvinyamupinyi zve endocrine zvakasara: chirwere chetrojeni, glandidzo yezvinyorwa, uye glands zvepabonde.
- Anogadzirisa mabasa ezvikamu zvakasiyana-siyana: itsvo, chibereko, mammary glands.
- Icho chikonzero nekuda kwepituitary kuti nhengo dzinokura uye dzakakura.
Ko gland yepituitary inoita sei mabasa aya? Zvose zviri nyore: iron inogadzira zviratidzo zvinoshamisa zvehomoni. Izvozvo zvinogadzirisa zvakananga kune dzimwe nhengo. Ichocho ndechokuti, chaizvoizvo, basa guru rehutu hwepituitary ndekubudisa mahomoni.
Mahomoni emucherechedzo wepituitary nemabasa avo
Iron inoparadzaniswa muzvikamu zvakasiyana. Mune imwe neimwe yega imwe yezvinhu zvinogadzirwa:
- Thyrotropic hormone inotungamirira kugadzirwa kweT3 uye T4 - hormone yekemikari. Ivo, ivowo, ndivo vane basa rekugadzirisa zviratidzo uye kushanda zvakanaka kwezvikamu zvemuviri wepamuviri, yemwoyo, nervous system.
- Murairo wehutano hwekubereka - ndizvo izvo gonadotrophic pituitary hormone .
- Adrenocorticotropic zvinhu zvinodiwa pakugadzirisa uye kuchengetedzwa kwe cortisol , cortisone, uye corticosterone inogadzirwa mu adrenal cortex.
- Kukura mahomoni ndiko kukura kwehomoni.
- Nokuda kwekubuda kwemasikana emadzimai, kushandiswa-kuwedzera-kukura maitiro, kumira kwekudya, luteotropic zvinhu zvinopindura.
- Vasopressin , yakabudiswa mushure mekunyoresa kwechiganda chepituitary, inoshanda semutongi wekushanda kwetsvo, moyo uye nervous system.
- Beta-endorphin ndeimwe yeiyo yakawanda kwazvo inobatsira. Iyi hormone inobatsira kurwisa anesthetize, inobatsira kugadzirisa kushushikana, inoderedza inzwi rehutano hwemitsipa, kana zvichidikanwa inoderedza kudya.
- Pasina basa rinoshanda uye oxytocin . Pakuberekwa, kuwanda kwehutano hwehutano kunobva pazviri. Anopawo mukaka mukugadzirwa panguva yekuvhunga . Uye iyo inokonzerwa nekuita zvepabonde.
Sezvaunogona kuona, huwandu hwakawanda hwehutano hwakakosha hunoenderana nehutano hwehukuru hwepea yakawanda.
