Hypothalamus imwe yezvimwe nhengo dzemuviri dzevanhu. Icho chiri pedyo nechepasi peuropi. Iye ndiye anokonzera kushanda zvakanaka kweganda repituitary uye chimiro chemasabolism chaiwo. Mahomoni anobudiswa mu hypothalamus anokosha zvikuru mumuviri. Ndivo mapeptidi ayo anokonzera zvirongwa zvakasiyana-siyana zvinoitika mumuviri.
Ndeapi mahomoni anobudiswa ne hypothalamus?
Mu hypothalamus kune masero emasero, ayo ari kukonzerwa nekugadzirwa kwemashimoni ose anokosha. Vanonzi neurosecretory masero. Pane imwe nguva, vanogamuchira mafungiro emafungiro akasiyana-siyana, ayo anopiwa nezvikamu zvakasiyana zvehurongwa hwemagandanga. Axons of neurosecretory masero anogumisa pamidziyo yeropa, paanoita axo-vasal synapses. Kupfurikidza nekupedzisira uye mahomoni anobudiswa akawedzerwa.
Iyo hypothalamus inobereka libinini nemasimine-iyo inonzi kunodzinga mahomoni. Izvi zvinhu zvinodiwa kuti utungamirire basa remasimoni yepituitary gland. Statins inokonzera kuderedza kushandiswa kwezvinhu zvakasununguka, uye liberian pakuwedzera.
Kusvika iye zvino, mahomoni anonyatsodzidza ye hypothalamus:
- Gonadoliberines. Aya mahomoni anokonzera kuwedzera nhamba yehomoni dzebonde dzakabudiswa. Vanobatanidzwawo mubatsiro rekugara kwemazuva ose uye kuumbwa kwechido chepabonde. Pasi pesimba rekuwanda kwe lyuliberin - imwe yemhando dzakasiyana-siyana dzegonadotypes - mazai ehosi akakura. Kana aya mahomoni asina kukwana, mukadzi anogona kukura kusununguka .
- Somatoliberin. Aya mahomoni, akabudiswa ne hypothalamus, anodiwa kusunungura kukura kwezvinhu. Vanofanira kunge vari kunyanya kusimbiswa muhuduku nevechidiki. Mukuda kwekushaiwa kwehomoni, dwarfism inogona kukura.
- Corticoliberin. Kutarisirwa kwekuwedzera kwekugadzirwa kwemakoroni eodrenocorticotropic muhutu hwepituitary. Kana iyo hormone isingabhadharwi mumari inodiwa, muzviitiko zvakawanda adrenal insufficiency inokura.
- Prolactoliberin. Ichi chinhu chinonyanya kushanda chichifanira kukura panguva yekuzvitakura uye munguva yose yeakisi. Ichi chinobudisa chinowedzera chiyero cheprolactin chakakonzerwa uye chinokurudzira kubudiswa kwemakumbo muzamu.
- Dopamine, melanostatin uye somatostatin. Vanodzivisa kutonhora kwehomoni inokonzerwa nemucherechedzo wepituitary.
- Melanoliberin. Inobatanidzwa mukugadzirwa kwemaranin uye kubereka kwemasero e pigment.
- Tyroliberin. Zvinotarisirwa kuvhara utachiona hwemakemikari uye kuwedzera thyroxine muropa.
Mutemo wekuvhara mahomoni e hypothalamus
Izvo chirwere chinotarisana chinopindura kurongeka kwekuvharwa kwehomoni. Mahomoni akawanda anowanzoita gland anobudiswa, kunyanya kuvharwa kwehomoni inotyisa. Ukama uhwu hahugoni kuita zvinodzvinyirira chete. Mune zvimwe zviitiko, inoshandisa maitiro ehomoni ye hypothalamus pane masero ari munharaunda yepituitary.
Hormone mishonga ye hypothalamus
Izvi zvinosanganisira:
- Sermorelin. Chifananidzo chekukura kwehomoni. Inopiwa zvikurukuru kuvana vaduku. Zvinorambidzwa panguva yekudzivirira uye munguva yekudzivirira.
- Bromocriptine. Yakashandiswa kukurudzira postsynaptic dopamine receptors. Inorayirwa kukanganisa kwe lactation.
- Okreotid. Inogona kuderedza kushandiswa kwekukura kwehomoni uye kubvisa basa rezvinyorwa zvinoputika. Iyo inorayirwa kuonda uye kuvhara matumbo.
- Rifatiroin. An analogue yehomoni ye hypothalamus ye tiropropin.
- Stylamine. Inogona kuderedza ropa kuderera mukati memitumbi, asi pasina kuchinja systemic blood blood.
