I pineal indlala

Indlala pineal (epiphysis) ohlobene epithalamus ngenkathi e diencephalon, futhi ahlelwe inkatho engajulile ohlukanisa elingenhla hillocks isihloko ubuchopho obuphakathi ngaphandle. Kuyini lokhu umzimba kanye nendzima yayo emzimbeni womuntu?

Njengezinye kwezitho zomzimba eziningi, le ndlala pineal bengayiqondi ngokugcwele, kodwa indima ebalulekile ukusebenza emzimbeni wethu akaphiki ubani. Ukuma le ndlala kungaba ovoid, eyindilinga noma oyindilinga. Isisindo esivamile we wendlala ngesikhathi kuphela onyakeni wokuqala wokuphila lenyuka lisuka kwabangaba 7 kuya ku-100 mg. Ngu eminyakeni 10 isisindo salo ngokuphindwe kabili, bese azizange zishintshe impilo yonke. isisindo salo e abadala imayelana 0.2 g, futhi ubude zingaba phakathi 8 kuya ku-15 mm. Ububanzi kulomzimba iyahlukahluka phakathi kwabantu 6 kuya ku-10 mm, futhi ukujiya - 4 kuya 6 mm. Ngezinye kakhulu phansi ndlala ebhekene bebheke ventricular ingaphakathi 3, kukhona ikhefu elincane. Indlala pineal imbozwe ngaphandle capsule zezinzwa equkethe igazi eliningi capillary anastomose ndawonye. Kule capsule ngaphakathi lo umzimba zingene trabeculae sakhiwa ezicutshini. Bahlanganyela a parenchyma pineal zibe tincetu ngabanye. Igazi ihlinzekwa emuva yensimbi kanye aphakeme imithambo cerebellar. emithanjeni yakhe uxhumeke umthambo ezinkulu zobuchopho noma nemingenela yayo. Njengoba imithambo yegazi ukungena ukuthi izicubu zomzimba nozwela yezinzwa.

I parenchyma we wendlala yakhiwa izakhi yeselula ezikuyo inqwaba. Ziyakwazi namangqamuzana akhethekile yezindlala ngokuthi pinealocytes (pineotsity). Inani ezincane eziqukethwe parenchyma gliatsity (lialnye amaseli). Indlala pineal e abadala kanye nabantu abadala ikakhulukazi ngokuvamile zitholakala ezifakwa bunjwa okungavamile (hourglass umzimba). Lezi ezifakwa neqhaza yokuthi insimbi kuba sengathi Isigaxa fir noma okwezithelo zemithi kamalibhele. Kuyinto ngenxa ukubukeka kwabo, le ndlala uthola igama layo. Iqhaza endocrine we ndlala pineal wukuthi amaseli ayo secrete izinto ezikhethekile ukuthi zivimbela umsebenzi indlala pituitary. Matasa emsebenzini waso ngaphambi nokuthomba. Le ndlala kudlala indima oqondile e ukulawulwa cishe zonke izinhlobonhlobo umzimba emzimbeni womuntu. Baziwa nemisebenzi ezinjalo indlala pineal, njengoba braking ukukhululwa hormone sokukhula nokuthuthukiswa isimila, ithonya ngokuziphatha okungokobulili ukuthuthukiswa ngokobulili.

Muva nje, indaba ephathwayo kakhudlwana futhi nehaba ngaphezulu "ukwenza kusebenze le ndlala pineal." Kubantu abaningi ngokuphelele akakwazi ukuqonda ukuthi ungakwazi kusebenze nezindlala endocrine , futhi kungani lokho? labo abanamathela Abaningi imithi ehlukile ukholelwa ukuthi le ndlala pineal akugcini nje efeza umsebenzi wayo bokuphila (ukukhiqizwa kwe-melatonin, i-hormone ukukhula, ukulawulwa isigqi begazi emzimbeni), kodwa indawo lapho okufakwayo (futhi okukhipha) komphefumulo emzimbeni womuntu. Bathi le ndlala pineal, ukusebenza kwawo lapho ingatholakala imikhuba esikhethekile ukusetshenziswa abazi-ke, ungakwazi ukunikeza control umuntu phezu isikhundla salo space kanye nesikhathi.

Nakuba ochwepheshe abakwazi ukuqinisekisa noma ukuphika ukubukwa idatha kwabanye abantu, ziyaqaphela ukuthi minyaka yonke izinguquko eziningi yangempela indlala pineal. Abanye bathi lokhu kuwubufakazi uhlobo olusha ukubukeka komuntu, nakuba kuba lutho okwamanje kungaqinisekiswa.

abasekeli abaningi we "pineal kusebenze indlala" inkolelo-mbono ukunikeza amakhasimende abo izindlela ezihlukahlukene zalo esekelwe imikhuba esoteric lasendulo, odokotela musa batusa eneka umzimba wakho engabazekayo hhayi kungase kutholakale ucwaningo.
