Kia ako tātou mō te toa iti i roto i tō tātou roro: te Repe Pituitary o Muri!

He rite tō tātou tinana ki tētahi mīhini whakamiharo, matatini hoki, kāore? E mōhio ana tātou katoa ko ngā mea katoa o tēnei mīhini kei roto i tō tātou roro e whakahaere ana. Engari i mōhio koe kei roto i tō roro he repe iti pērā i te wheua iti, e tuku ana i ngā homoni tino nui e whakahaere ana i te nui o te wai i roto i tō tinana, e meinga ai te kōpū kia kōpiri i te wā whānau, ā, e hanga ana i taua hononga whakamiharo i waenganui i te whaea me te tamaiti? Koinei tā tātou e kōrero ai i tēnei rā. Ka huaina tēnei ko te Repe Pituitary. I tēnei rā, ka kōrero taipitopito tātou mō tētahi wāhanga motuhake o taua mea, ko te Pituitary o muri.

Tuatahi, kia titiro tātou, he aha te repe pituitary?

Whakaarohia he kamupene nui tō tinana. Kātahi ko te Tumu Whakahaere o taua kamupene ko te wāhanga o te roro e kiia nei ko te hypothalamus. Kei raro iho i tēnei Tumu Whakahaere he kaiwhakahaere whānui. Ko te repe pituitary tērā. He mea tino nui tēnei kaiwhakahaere, nā te mea e whakahaere ana i te mahi a ngā repe maha atu i roto i te tinana.

Kei raro i tō roro tēnei repe pituitary, kei muri i tō ihu, i tētahi wāhi tino haumaru. E rua ngā wāhanga. Pērā i te tēpu whakawātea o mua i te tari me te tari o muri.

1. Te Pituitary o mua: Koinei te wāhanga nui rawa atu, tino pukumahi hoki. Ka whakaputa, ka tuku hoki i ngā homoni maha e pā ana ki te tipu o te tinana, te mahi tairoi, me te mahi ā-ira.

2. Te Pituitary o Muri: Koinei tā tātou toa. He iti ake i te pituitary o mua. Kāore e whakaputa i ngā homoni, engari e rongoa ana i ngā homoni motuhake e rua i hangaia, i tukuna hoki e te hypothalamus, ā, ka tukuna ki roto i te toto ina hiahiatia.

Ko te pūnaha e whakauru ana i ngā repe katoa e whakaputa ana i ngā homoni, tae atu ki te repe pituitary, e kiia ana ko te pūnaha endocrine . Koinei te whatunga e whakawhitiwhiti karere matū ana i roto i te tinana.

Nā, he aha aua homoni motuhake e rua e tukuna ana e te Posterior Pituitary?

E ai ki tā mātou i kōrero ai i mua ake nei, he rite te Pituitary o muri ki tētahi whare putunga. E rua ngā "taonga" tino nui e rongoatia ana i konei. He homoni e rua. Ko ēnei e rua ka hangaia e te Hypothalamus. Ina tae mai he karere mai i reira mā roto i ngā io, ka tukuna e te Pituitary o muri ēnei homoni ki roto i te toto.

Anei tētahi whakamārama māmā mō ēnei homoni e rua me ā rāua mahi.

Whakaarohia he wā e werawera ana koe, e matewai ana hoki. I taua wā, ka mātotoru ake tō toto. Ka mōhio te hypothalamus i roto i te roro ki tēnei, ka tukuna he tohu ki te Posterior Pituitary, e mea ana, "Āe, tāpirihia he ADH ki roto i te toto." Kātahi ka haere te ADH ka kī atu ki ngā whatukuhu, "Whakamahia he wai kia iti, kaua e nui rawa te mimi." Ko te wā tēnā ka heke te nui o te mimi e tukuna ana e koe, ā, ka pouri ake tōna tae. Ina nui te wai i roto i a koe, ka rerekē te āhua. Ka heke ngā taumata ADH, ā, ka tukuna te wai nui hei mimi. He whakahaere whakamiharo tēnei?

He aha ngā mate ka hono atu ki te Posterior Pituitary?

I te nuinga o te wā, he onge ngā mate nui e pā ana ki tēnei repe. Heoi, i ētahi wā, ka puta ake ētahi raruraru nā te nui rawa o te huna (hypersecretion) te kore rānei o te huna (hyposecretion) o ēnei homoni ADH me te oxytocin.

1. Te korenga o te ADH i roto i te toto

Ki te whakaitihia te hanga, te tukunga rānei a te tinana i te homoni ADH, ka ngaro i ngā whatukuhu te tohu ki te mimiti anō i te wai e hiahiatia ana e rātou. Ko te tikanga o tēnei, tata ki te wai katoa e inumia ana e koe ka mutu ki roto i tō mimi. Ko te ingoa o tēnei mate ko te Central Diabetes Insipidus (CDI) .

Ka pā mai pea tēnei āhuatanga i te kino o te hypothalamus, te pituitary rānei. I ētahi wā, kāore e kitea he take.

Ngā tohu matua:

• Te mimi nui rawa (Polyuria): Tērā pea ka puta he maha rita o te mimi i te rā. Me haere pea koe ki te wharepaku i ngā wā katoa.
• Te matewai nui (Polydipsia): Ahakoa te nui o te wai e inuhia ana e koe, ka rite tonu koe ki te kore e ranea. I te ngaronga o te wai i roto i tō tinana, ka tukuna e tō roro he tohu kia inu tonu koe i te wai.
• Te matewai: Ki te kore koe e inu nui i te wai, ka ngaro pea te wai i roto i tō tinana.
• Ngenge: Ko te ara ake i ngā wā katoa i te pō ki te mimi ka whakararuraru i tō moe, ā, ka ngenge koe i te roanga o te rā.

2. Mena ka piki te homoni ADH (Te nui o te whakaputanga o te ADH)

He rerekē tēnei i te mea o mua. Mēnā he nui rawa te homoni ADH i roto i te tinana, ka mimiti anō ngā whatukuhu i te nui rawa o te wai ki roto i te tinana. Ka puta he nui o te mimi. Ka kohia te wai i roto i te tinana, ā, ka tino iti te taumata konutai (tote) i roto i te toto. Ka kiia tēnei āhuatanga ko te SIADH (Syndrome of Inappropriate Antidiuretic Hormone Secretion) .

Ngā mea ka taea te whakaputa i tēnei:

• Ētahi rongoā (hei tauira, ētahi rongoā mō te mate huka me te mate haurangi).
• I muri i ngā pokanga i mahia i raro i te mate whakamoe.
• Ngā āhuatanga pēnei i te whara o te roro, te mate pāwera, te whiu rānei.

Ngā tohu matua (he maha ngā wā ka puta mai i te iti o te konutai i roto i te toto):

• Whakapairuaki me te ruaki.
• Te mamae o te upoko.
• Te āhua nei kei te ngaro tō taurite, ā, tata tonu koe te hinga.
• Ngā huringa hinengaro pērā i te ngaronga o te mahara me te ohorere.

3. Ngā raruraru e pā ana ki te homoni Oxytocin

Ina hoki, he tino onge ngā mate e puta mai ana i te iti, te teitei rānei o tēnei homoni, te oxytocin. He tino onge te mate.

• Mena he iti te oxytocin: Tērā pea kāore te kōpū e kuhu tika i te wā e whānau ana, ā, tērā pea kāore te waiū e puta mai i muri i te whānautanga o te pēpi.
• Ki te piki ake te oxytocin: He tino onge hoki tēnei. Ka nui rawa te tipu o ngā uaua o te kōpū, ka uaua ai te pupuri a te pēpi i te tamaiti.

Me pēhea koe e mōhio ai mēnā he raruraru kei te Posterior Pituitary?

Mena kei a koe ngā tohu i kōrerotia i mua ake nei, ka pātai tuatahi tō tākuta ki a koe mō ō tohu. Kātahi ka whakahaerehia pea ētahi whakamātautau hei tiki pikitia tika mō ngā taumata o ō homoni.

• Ngā Whakamātautau Toto: Ka taea te ine i ngā mea pēnei i te taumata o te homoni ADH me ngā taumata konutai i roto i te toto.
• Ngā Whakamātautau Mimi: Ka taea e koe te kite i te matotoru, te angiangi rānei o tō mimi.
• Matawai MRI: Mā tēnei ka āwhina i te tirotiro mō ngā pukupuku, ngā pakaru rānei o te repe pituitary, o te hypothalamus rānei.

Ka whakatau tō tākuta i te maimoatanga i runga i ngā hua o ēnei whakamātautau.

Āhea ahau me toro atu ki te tākuta?

He tino onge te nuinga o ngā mate kua kōrerotia e tātou. Heoi, ki te kite koe i tētahi panonitanga o tō tinana, he pai ake kia kaua e warewaretia.

Ina koa, ki te mea kei a koe tētahi, ētahi rānei o ngā tohu e whai ake nei, kaua e moumou taima, me toro atu ki tō tākuta.

• Ki te mea he nui rawa tō matewai e kore e taea te whakaaro, me te mimi pinepine, nui rawa hoki .
• Mena ka pāngia koe e te whakapairuaki, te ruaki, te ānini, me te āhua taurite kore, kāore he take.
• Ki te mea ka pā whakarere mai te āhua kua pōhēhē tō mahara, ā, kāore e taea e koe te arotahi .

I ngā wā pēnei, mā te toro atu ki te tākuta me te whai i ētahi whakamātautau māmā ka āwhina i a koe ki te whakatau mēnā he raruraru, kāore rānei. Nō reira kaua e wehi ki te rapu tohutohu hauora.
