Me ako noa tātou mō te repe pituitary o muri.

Kua whakaaro kē koe e hia ngā wāhanga iti o tō tātou tinana e mahi ana i te nui o te mahi? I tēnei rā ka kōrero tātou mō tētahi repe iti rawa e mahi ana i ngā mahi whakamiharo. Ko te repe pituitary te ingoa. Ina koa, ka arotahi tātou ki te wāhanga o muri o taua repe, te "Posterior Pituitary".

He aha tēnei repe pituitary? He aha te mea motuhake mō te taha o muri?

Ki te kī māmā noa iho, he repe iti te repe pituitary, he rite te rahi ki te pī, kei te pūtake o tō tātou roro, i raro i te hypothalamus. He wāhanga tino nui o tō tātou pūnaha endocrine. Whakaarohia, ahakoa he iti, ko ia te kaiwhakahaere o te nuinga o ngā homoni tino nui o tō tātou tinana.

E rua ngā wāhanga matua o tēnei repe pituitary:

1. Te Pūwero o Mua

2. Te Pūnaha o Muri - Koinei te mea e kōrerohia ana i tēnei rā, arā, te "Pūnaha o Muri".

He maha ngā homoni ka whakaputaina e te repe pituitary, ka tukuna hoki. Heoi, he mea motuhake te pituitary o muri. E rua noa iho ngā homoni ka rongoatia, ka tukuna hoki e ia ina hiahiatia. Ko ēnei homoni e rua:

• Oxytocin
• Ko te Hormone Antidiuretic (ADH), e kiia ana ko te Vasopressin.

Inaianei pea kei te whakaaro koe, "He aha tēnei hypothalamus?" He wāhanga anō hoki te hypothalamus o tō tātou roro. He maha ngā mea e whakahaere ana i a ia, tae atu ki te toto totoka, te tere o te manawa, te pāmahana o te tinana, me te nakunaku. He mea whakamiharo, e hono ana te repe pituitary ki te hypothalamus mā te kakau iti. Ka kiia tēnei ko te kakau pituitary. Mā tēnei kakau ka kī atu te hypothalamus ki te repe pituitary, "Āe, tukuna taua homoni inaianei."

He aha te Pūnaha Endocrine? Tēnā whakamāramahia mai.

He pātai pai! Ko te pūnaha endocrine he whatunga o ngā repe i roto i tō tātou tinana e whakaputa ana i ngā matū e kiia nei ko ngā homoni, ā, ka tukuna tika atu ki roto i te toto.

He rite ngā homoni ki ngā karere e kawe ana i ngā karere i roto i ō tātou tinana. Ka haere rātou i roto i te toto, ka tohutohu i ō tātou whekau, kiri, uaua, me ētahi atu kiko he aha te mea hei mahi, me te wā hoki hei mahi.

Ko ngā repe me ngā whekau matua e hanga ana i tō tātou pūnaha endocrine ko:

• Hypothalamus
• Repe Pituitary
• Te repe tairoiti
• Ngā repe parathyroid
• Ngā repe adrenal
• Repe pineal
• Pancreas
• Ngā ovaries (i roto i ngā wāhine)
• Ngā whekau (ngā whekau) (tāne)

He aha ngā homoni e tukuna ana e te repe pituitary o muri? He aha tā rātou mahi?

E ai ki tā mātou i kōrero ai i mua ake nei, e rua ngā momo homoni matua e rongoatia ana e te repe pituitary o muri, ā, e tukuna ana hoki. Ko ēnei homoni ka hangaia e te hypothalamus. Engari ka rongoatia, ka tukuna ana ina hiahiatia e te repe pituitary o muri.

1. Hormone Antidiuretic (ADH) Vasopressin rānei:

• He mea tino nui tēnei homoni. Mā tēnei homoni ka āwhina i te tinana ki te mimiti i te nui o te wai e tika ana ina tātarihia te toto e ō tātou whatukuhu. He māmā noa iho, ka āwhina te ADH ki te whakahaere i te taurite wai i roto i tō tātou tinana.

2. Okitōtini:

• Mō ngā wāhine, ka āwhina i te whānautanga mā te whakawhāiti i te kōpū i te wā e whānau ana. Ka whakaoho hoki i ngā ū kia whakaputa waiū. Ka pā hoki te oxytocin ki te hononga i waenganui i te whaea me te tamaiti.
• I roto i ngā tāne, ka pā pea tēnei homoni ki te hononga i waenga i ngā mātua me ngā tamariki. Ehara i te mea koinā anake, engari ka āwhina anō hoki te oxytocin ki te pana i te parāoa me te wai purapura ki mua i te wā e puta ai te huakita.

Nā, he aha te mahi matua a te pituitary o muri?

Ko te mea nui ko te penapena i te oxytocin me te homoni antidiuretic (ADH) ka tukuna ina puta mai he tohu mai i te hypothalamus. Ka tukuna e te hypothalamus ēnei tohu mā roto i ngā tohu io e puta mai ana i te kakau pituitary i kōrerohia e tātou i mua ake nei.

He aha te hononga o te Posterior Pituitary ki ētahi atu okana?

He kōrero tino whakamere tēnei. E hono tika ana te pituitary o muri ki te hypothalamus. Nā te mea ka hangaia e te hypothalamus te oxytocin me te ADH, ā, ka kī atu ki a rātou te wā tika hei tuku i a rātou.

Hei tāpiritanga:

• I roto i ngā tāne, ka mahi te oxytocin ki te kōpū, ki ngā repe ū (ngā ū), me ngā vas deferens.
• Ko te mahi nui a te ADH (hormone antidiuretic) ko ō tātou whatukuhu.

Kei hea te pito o muri o te pituitary? He aha tōna rahi?

Kei te pūtake o tō tātou roro te repe pituitary, i muri i te piriti o tō tātou ihu, i raro tonu i te hypothalamus. Kei roto i tētahi kōhao iti i roto i te wheua sphenoid. Ko te Sella Turcica tēnei.

He rite te rahi o te repe pituitary katoa ki te pī, tata ki te 1/3 o te inihi. Ko te pituitary o muri te wāhanga o te repe e anga ana ki muri. He iti ake i te pituitary o mua. Tata ki te 80% o te taumaha o te repe pituitary katoa te taumaha o te pituitary o mua.

He aha ngā mate me ngā āhuatanga e pā ana ki te Posterior Pituitary?

Ko ngā raruraru matua ka pā ki te pituitary o muri ko te nui rawa o te oxytocin, te homoni antidiuretic (ADH) rānei.

He onge te nuinga o ēnei āhuatanga. Waihoki, ka pā pea ngā pukupuku ki te repe pituitary o muri, engari he onge anō hoki. Ko ngā pukupuku pituitary te nuinga o te wā ka puta i te repe pituitary o mua.

Te whakahekenga iti o te homoni antidiuretic (ADH)

Nā te hekenga o te hanga ADH i roto i te hypothalamus, nā te hekenga rānei o te tukunga ADH mai i te repe pituitary tēnei i hua ai. Ko te nuinga o te wā ka puta mai tēnei i te kino o te hypothalamus, o te pituitary rānei o muri. I ētahi wā ka puta mai anō hoki i te whakarerekētanga ira. I ētahi wā, kāore e mōhiotia te take.

Ina iti iho ngā taumata ADH i te mea noa, kāore e taea e ngā whatukuhu te mimiti anō i te nui o te wai e hiahiatia ana. Ka nui ake te wai ka puta i roto i te mimi (ka memeha te mimi), ka whakaiti i te nui o te wai i roto i te toto, ā, ka piki ake tōna kukū.

Mā te korenga o te ADH ka hua ake he mate pākia wai onge e kiia nei ko te "Central Diabetes Insipidus - CDI". Kaua tēnei e whakapoauautia ki te "Diabetes Mellitus", he rerekē rawa ngā mea e rua. Ka taea e te CDI te whakararu i te ora mēnā kāore e rongoatia tika.

Ko ngā tohu o te CDI ko:

• Te mimi pinepine `(Polyuria)`
• Te matewai nui (Polydipsia)
• Te ngenge (me ara ake i ngā wā maha i te pō ki te mimi)
• Te maroketanga

Te nui rawa o te whakaputanga o te homoni antidiuretic (ADH)

Nā te pikinga ake o te hanga ADH i roto i te hypothalamus, nā te pikinga ake rānei o te tukunga ADH mai i te pituitary o muri, ka puta tēnei āhuatanga. Ka kiia tēnei āhuatanga ko te `(Syndrome of Inappropriate Antidiuretic Hormone secretion - SIADH)`. Ina piki ake te nui o te ADH, ka nui rawa te wai e puritia ana e te tinana. Kātahi ka tino kukū te mimi, ā, ka nui ake te wai me te memeha o te toto.

He maha ngā take e piki ake ai ngā taumata SIADH me ADH. Ko ētahi o ngā take noa ko:

• ētahi rongoā (hei tauira, ētahi rongoā mō te mate huka momo 2, rongoā mō te mate haurangi)
• Ngā pokanga e mahia ana i raro i te mate whakamoe whānui
• Ngā mate o te roro (ngā whara, ngā mate pāwera, te whiu)
• Ngā pokanga roro e pā ana ki te hypothalamus

Ko ngā tohu o te pikinga o ngā taumata ADH e puta pinepine ana i te iti o ngā taumata konutai i roto i te toto. Ko ngā tohu o te iti o te konutai i roto i te toto ko:

• Whakapairuaki me te ruaki
• Mamae upoko (headache)
• Te ngaronga o te taurite (tērā pea ka hinga)
• Ngā huringa hinengaro (pōhēhē, ngaronga mahara)

Te korenga o te Oxytocin

He āhuatanga tino onge tēnei.Ina heke te taumata o te oxytocin i raro iho i te tikanga, ka mutu te pupuhi o te kōpū, ka mutu te tukunga o te waiū i te wā e whānau ana. Ahakoa he onge, ko te tino take o tēnei ko te mate e kiia nei ko te "Panhypopituitarism." Koinei te wā e iti iho ana te taumata o ngā homoni katoa i roto i te repe pituitary i te tikanga.

Te nui rawa o te huna o te Oxytocin

He tino onge hoki tēnei. Ka kiia tēnei he paitini o te oxytocin. Ina teitei ake ngā taumata o te oxytocin i te mea noa, ka nui rawa te mahi a te kōpū. Ka piki ake te papatipu uaua o te kōpū (hypertrophy), ā, kāore e ranea te wāhi mō te tamaiti i roto i te kōpū, ka taea te whakawhāiti i te hāputanga.

He whakamātautau anō kei reira hei tirotiro i te hauora o taku repe pituitary o muri?

Mena kei a koe ngā tohu e pā ana ki ngā raruraru o te repe pituitary o muri, ka tonoa pea e tō tākuta kia whakamātauria ō taumata ADH me/ranei oxytocin.

• Mā te whakamātautau toto ADH ka āwhina i te tautuhi i te ngoikore, te taikaha rānei o te ADH, me te kimi i te pūtake.
• Ka taea te whakamātautau i ō taumata oxytocin i roto i ngā wai maha, pērā i te huware, te toto, te plasma, te mimi, me te wai cerebrospinal.

Mena he rerekē ngā hua o te whakamātautau, ka tūtohu pea tō tākuta i tētahi whakamātautau whakaahua, pērā i te MRI (Magnetic Resonance Imaging), hei tirotiro i tō repe pituitary.

Āhea ahau me toro atu ki te tākuta?

Mena kei a koe ngā tohu o te `(Central Diabetes Insipidus - CDI)` me te `(Syndrome of Inappropriate Antidiuretic Hormone secretion - SIADH)` rānei, kia kite koe i tō tākuta.

Kia maumahara, he onge te nuinga o ngā raruraru hauora e pā ana ki ngā mate o te pituitary o muri. Engari ki te mea he tohu hou, he tohu āwangawanga rānei āu, he pai ake te kōrero ki te tākuta. Ka taea e rātou te whakahaere i ētahi whakamātautau māmā hei tirotiro i tō hauora.

Ngā mea tino nui hei maumahara mā tātou mai i ngā mea kua kōrerotia e tātou (Karere hei tango mā te kāinga)

Āe, ko tāku tumanako kua mārama pai koe ki tēnei wāhanga iti engari he mea nui e kīia nei ko te "Posterior Pituitary" i kōrerohia e tātou i tēnei rā. He māmā noa iho:

• Ko te pituitary gland te wāhanga o muri o te repe pituitary gland i roto i tō tātou roro.
• Ko te nuinga o te wā , ka rongoa, ka tukuna hoki e ia ngā homoni e rua e kīia ana ko te oxytocin me te homoni antidiuretic (ADH). Ka hangaia ēnei homoni e te hypothalamus.
• Ka āwhina te ADH ki te whakahaere i te toenga wai i roto i tō tātou tinana .
• He mea nui te oxytocin mō te whānautanga, te whāngai u, me te hononga tangata .
• Mā ngā rerekētanga o ēnei homoni ka pā mai ngā raruraru hauora (ahakoa he onge) pērā i te "Central Diabetes Insipidus - CDI" me te "SIADH".
• Mena ka pā mai ētahi tohu rerekē, he mea whakaaro nui kia rapu tohutohu hauora.

He tino mīharo ō tātou tinana, kāore? He mea whakamiharo te whakaaro ki te nui o te mahi ka taea te mahi me tētahi wāhanga iti nei!
