Me ako noa tātou mō te Repe Pituitary o mua (Adenohypophysis): te rūrū iti i roto i tō tātou roro!

Kua whakaarohia e koe te nui o te mahi a tētahi wāhanga iti o tō tātou tinana? Ko tētahi o aua wāhi whakamiharo ko te repe pituitary o mua e kōrerohia ana e tātou i tēnei rā. E kiia ana hoki e ētahi ko te "Adenohypophysis". Pērā i te kaiārahi o tētahi ōkestra, ko tēnei repe te kawenga mō te whakaputa me te tuku i ngā homoni e whakahaere ana i ngā mahi tino nui o te tinana.

Nā, he aha tēnei repe pituitary o mua?

Ki te kī ngāwari, koinei te wāhanga o mua o tō repe pituitary. He repe iti te repe pituitary, he rite te rahi ki te pī, kei te pūtake o tō roro, i raro noa i te hypothalamus. He wāhanga tēnei o tō pūnaha endocrine. Arā, ko te wāhanga e whakahaere ana i te mahi a ngā momo repe i roto i te tinana.

Whakaarohia e rua ngā wāhanga o tō repe pituitary: te repe o mua (koinei te repe pituitary o mua e kōrerohia ana i tēnei rā) me te repe o muri. Ko tēnei repe o mua te mea e hanga ana i te ono (6) o ngā homoni, ā, ka tukuna atu ki roto i te tinana. Ko ēnei homoni te mea e hiahiatia ana e tō tātou tinana:

• Te tipu (ka tipu ake tātou)
• Te pākia o te tinana (te whakaputa pūngao, te tahu i ngā mea)
• Te momonatanga (te kaha ki te whānau tamariki)
• Te urupare ki te ahotea
• Te whāngai ū (mō ngā whaea)

He maha ngā mea nui e whakahaerehia ana. Ahakoa he iti ia, he tangata pukumahi, he tangata mana nui hoki!

Nā, he aha ngā homoni motuhake e hangaia ana e te repe pituitary o mua?

E ono ngā homoni matua e hanga ana i tēnei rangatira iti. Me titiro tātou ki ā rātou mahi.

1. Te Hormone Adrenocorticotropic (ACTH): Koinei te mea e whakaoho ana i ō repe adrenal ki te whakaputa cortisol, e mōhiotia ana ko te "hormone ahotea," me ētahi atu homoni. He mea tino nui tēnei i ngā wā ohorere, pērā i te wā e mataku ana koe.

2. Homoni whakaoho-pūpū (FSH): I roto i ngā tāne, ka whakaoho i ngā hua manu kia puta he parāoa. I roto i ngā wāhine, ka whakaoho i ngā ovaries kia pakari ngā hua manu, ka whakarite i a rātou mō te whakaputa uri, ā, ka whakaputa i te homoni estrogen.

3. Hormone Luteinizing (LH): Mena he wahine koe, ka whakaohokia e te LH ngā ovaries ki te whakaputa i te progesterone. Mena he tāne koe, ka whakaohokia e ia te whakaputanga o te testosterone.

4. Te Homoni Tipu Tangata (HGH): He mea nui tēnei mō te tipu o ngā tamariki nohinohi. Ka āwhina i a rātou kia roa ake, kia whanake hoki he tinana uaua. Mō ngā pakeke, ka āwhina i te pupuri i ngā uaua me ngā wheua hauora, ā, ka pā ki te āhua o te penapena ngako tinana.

5. Prolactin:Ka whakaoho tēnei homoni i te whakaputanga waiū i muri i te whānautanga o te pēpi a te whaea. Ka pā anō hoki ki te huringa paheketanga, te momonatanga (te kaha ki te whānau tamariki), me te mahi ā-ira tangata.

6. Te homoni whakaohooho tairoiti (TSH): Koinei te mea e kī ana ki tō repe tairoiti kia hanga me te tuku i ana ake homoni. He mea nui ngā homoni tairoiti hei pupuri i te tere o te pākia o te tinana.

Titiro mai, e hia ngā mahi rerekē ka taea te mahi i roto i tēnei wāhi iti!

He pēhea te mahi a te repe pituitary o mua me ētahi atu whekau?

E hono tika ana tō repe pituitary o mua ki tētahi wāhanga o tō roro e kiia nei ko te hypothalamus. Ka tukuna e te hypothalamus ngā "hormone tuku" me ngā "hormone aukati" pērā i te somatostatin me te dopamine ki roto i te toto mā te awa pituitary (he wāhanga iti rite ki te ngongo e hono ana i te roro me te repe pituitary). Ka whakaoho, ka aukati rānei ēnei homoni tuku i te hanga o ngā homoni e te repe pituitary o mua. He rite te hypothalamus me te repe pituitary o mua ki ētahi tāngata e kōrero tonu ana tetahi ki tetahi, e whakawhitiwhiti kōrero ana.

I muri i te tukunga o ngā homoni mai i te repe pituitary o mua, ka taunekeneke rātou ki ētahi atu okana, repe, me ngā kiko o roto i tō tātou tinana, ā, ka pā ki ēnei. Hei tauira:

• Ō tātou wheua, uaua, me ētahi atu whekau o roto
• Ngā Repe Adrenal
• Repe Tairoiro
• Ngā ovaries me ngā testicles (arā, ngā repe whakaputa uri)
• Ngā repe ū (ngā repe whakaputa waiū)

Kei hea tonu te wāhi e tū ai tēnei repe pituitary o mua?

E ai ki tā mātou i kōrero ai i mua ake nei, kei te pūtake o tō roro tō repe pituitary, i muri i te piriti o tō ihu, i raro noa iho i te "Hypothalamus." Kei roto i tētahi rūma iti, i tētahi pēke rānei, i roto i tētahi wheua i roto i tō angaanga e kiia nei ko te wheua sphenoid. Ka karangatia tēnei e ngā tākuta ko te "Sella Turcica."

E rua ngā pūrua o tō repe pituitary e hono ana tetahi ki tetahi. Kei mua te repe pituitary o mua, e anga ana ki mua o tō mahunga. Kei muri te repe pituitary o muri. Engari he mea whakamiharo, he nui ake te repe pituitary o mua i te repe o muri. Tata ki te 80% o te taumaha o te repe pituitary katoa kei tēnei wāhanga o mua.

He aha ngā raruraru ka puta mai i te repe pituitary o mua?

Nā te mea he maha ngā homoni nui e whakaputaina ana e tēnei repe, ka taea e ngā raruraru ki a ia te arahi ki ngā momo raruraru hauora. Ko te tikanga, ka taea te wehewehe i ēnei raruraru ki ngā wāhanga e rua:

1. Te ngoikore o te pituitary gland: Ko te tikanga he iti ake ngā homoni e whakaputaina ana e te repe pituitary gland i te mea e tika ana.

2. Te Hiperpituitarism:Ko te tikanga o tēnā he nui ake ngā homoni e whakaputaina ana e te repe pituitary i te mea e tika ana.

He maha ngā take matua e puta ai ēnei āhuatanga e rua:

• Ngā pukupuku o te repe pituitary (adenomas): He maha ngā wā he pukupuku kore-matepukupuku (pai).
• Te kino ki te repe pituitary o mua, te hypothalamus, te awa pituitary rānei: Ka puta pea tēnei i tētahi aituā, i tētahi mate, i te toto rānei (hei tauira, te pituitary apoplexy).
• Ngā āhuatanga ira: Hei tauira, ngā āhuatanga pēnei i te `(Multiple Endocrine Neoplasia - MEN)`.

Ko ētahi āhuatanga e pā mai ana i te 'Hypopituitarism' (te korenga o te homoni):

Ka taea e te korenga o tētahi, neke atu rānei o ngā homoni te whakaputa i ngā āhuatanga pēnei i:

• Te ngoikore tuarua o te repe adrenal: Te ngoikore o te repe adrenal nā te hekenga o te homoni ACTH.
• Te Kore o te Homoni Tipu (GHD): Te hekenga o te taumata o te homoni HGH. Mō te hunga poto, ka taea te aukati i te tipu.
• Te ngoikore o te ira tangata i waenganui o te kōpū: Te hekenga o te hanga o ngā homoni ira tangata mai i ngā repe whakaputa uri (ngā ovaries me ngā testicles) nā te hekenga o ngā taumata o te FSH me/ranei te LH.
• Te hypothyroidism pokapū: Te mate thyroid nā te hekenga o te homoni TSH.

Ko ētahi āhuatanga e hua mai ana i te 'Hyperpituitarism' (te pikinga o ngā taumata homoni):

Mā te pikinga ake o tētahi, neke atu rānei o ngā homoni ka puta ngā āhuatanga pēnei i:

• Acromegaly: He mate onge e puta mai ana i te nui rawa o te HGH i roto i ngā pakeke. I roto i tēnei mate, ka tipu rerekē ngā wheua me ngā kiko.
• Te Gigantism: He tamaiti, he taiohi rānei, he tino roa rawa, e nui rawa ana te taumata o te homoni HGH i roto i tōna tinana. He tino onge hoki tēnei.
• Te mate a Cushing: Mā te nui rawa o te homoni ACTH ka nui rawa te cortisol e puta mai i ngā repe adrenal. He momo mate tēnei e kiia nei ko te mate a Cushing.
• Hyperprolactinemia: Te nui rawa o te hanga o te homoni prolactin.
• Te hyperthyroidism pokapū: He nui rawa te mahi a te repe tairoi nā te nui rawa o te whakaputanga TSH. He tino onge tēnei take o te hyperthyroidism.

Kia ako tātou mō ngā Pituitary Adenomas.

He pukupuku te pituitary adenoma e tupu ana i roto i tō repe pituitary. Kaua e manukanuka, ko te nuinga o te wā he pukupuku puhoi te tipu, ehara i te matepukupuku (pai).

Heoi, ka taea e ēnei adenoma te ārai i ngā pūtau pituitary noa, ā, ka kore e mahi tika. Ka taea e tēnei te whakaputa i te "Hypopituitarism" (te iti o te hanga homoni), inā koa he nui te pukupuku. I ētahi wā, ka taea hoki e ēnei pukupuku te whakaputa i ngā homoni tāpiri, ka taea ai te "Hyperpituitarism" (te nui o te hanga homoni).

He maha ngā momo adenoma pituitary o mua e whakaputa ana i ngā homoni (e mahi ana):

• Prolactinoma: Ka whakaputa i te homoni prolactin nui rawa atu. Koinei te momo adenoma pituitary e tino kitea ana.
• Adenoma Somatotroph: Ka nui rawa te homoni tipu (GH) e whakaputa ana.
• Adenoma corticotroph: Ka whakaputa i te homoni ACTH nui rawa.
• Adenoma tirotroph: Ka nui rawa te homoni TSH e puta ana.
• Gonadotroph adenoma: Ka whakaputa i ngā homoni LH me FSH nui rawa.

He whakamātautau anō kei reira hei tirotiro mēnā kei te ora taku repe pituitary o mua?

Āe, ki te mea kei a koe ngā tohu o tētahi raruraru ki te repe pituitary o mua, tera pea ka whakahau tō tākuta kia tirohia ngā taumata homoni. He whakamātautau toto ēnei i te nuinga o te wā .

Mena ka puta he āhuatanga rerekē i ngā hua o te whakamātautau toto, ka tūtohu pea tō tākuta i tētahi mea pēnei i te matawai MRI hei tirotiro i tō repe pituitary.

Nā, me aha tātou hei pupuri i te hauora o tēnei repe pituitary o mua?

Ki te pono, kāore e taea te ārai i ēnei raruraru o te repe pituitary i ngā wā katoa. Engari ko tētahi mea nui ka taea e koe ko te tiaki i tō mahunga. Ka taea e ngā whara o te mahunga, inā koa ngā whara roro whara (TBI), te kino i tō repe pituitary. Ki te tupu tēnā, ka nui rawa, ka iti rawa rānei ngā homoni e puta mai ana.

Anei ētahi mea ka taea e koe te mahi hei ārai i ngā whara o te mahunga me te roro:

• Me mau tonu te whitiki nohoanga i a koe e eke ana i roto i te waka.
• Āta taraiwa.
• Me mau he potae i te wā e eke pahikara ana, e motopaika ana, e takaro ana rānei i ngā hākinakina kaha.
• Me mahi i ngā mahi hei ārai i te hinganga, inā koa mēnā he nui te tūponotanga o te hinganga. Ka taea e koe te mahi i ngā mea pēnei i te tango i ngā arai i tō whare, te whakamahi i tētahi taputapu āwhina hikoi, me te pupuri i tō tirohanga kia mārama.
• Mena he tamariki nohinohi āu, me pupuri kia haumaru ō rātou wāhi tākaro.

Kia maumahara: He okana iti, engari he kaha, he mea nui hoki tō repe pituitary o mua, e whakaputa ana i ngā homoni maha e pā ana ki ngā āhuatanga maha o tō tātou hauora.

Hei whakamutunga, ngā mea hei maumahara

Nō reira, ka kite koe i te hiranga o tēnei repe pituitary o mua i roto i tō tātou tinana. Nā reira, he uaua pea i ētahi wā te whakatau mēnā he raruraru tēnei repe pituitary, he take kē atu rānei ētahi tohu.

Ko te mea nui, ki te puta he tohu hou rerekē ki a koe, ki te mea rānei kei te āwangawanga koe mō tētahi tohu kua pā mai ki a koe, me toro atu koe ki te tākuta me te kōrero mō taua tohu.Ka taea e rātou te whakahaere i ētahi whakamātautau māmā hei tirotiro i tō hauora. Mēnā he raruraru, ka taea te tautuhi me te rongoā wawe.
