Qhov sib txawv tseem ceeb ntawm hypothalamus thiab pituitary caj pas yog hypothalamus yog ib lub qog almond-loj nyob hauv qab thalamus, uas yuav pab kom zais cov tshuaj hormones lub luag haujlwm los txhawb lossis inhibiting cov tshuaj hormones nyob rau hauv lub anterior pituitary, thaum lub caj pas pituitary yog. ib lub caj pas me me uas txuas rau lub hypothalamus uas khaws cov tshuaj hormones los ntawm hypothalamus thiab tso rau hauv cov hlab ntsha.
Hypothalamus thiab pituitary caj pas complex tuaj yeem piav qhia raws li qhov chaw hais kom ua ntawm tib neeg endocrine system. Qhov no feem ntau secretes ntau cov tshuaj hormones uas ncaj qha tsim cov lus teb hauv cov ntaub so ntswg. Ntxiv mus, qhov chaw no kuj tsim cov tshuaj hormones uas tswj cov synthesis thiab tso tawm cov tshuaj hormones ntawm lwm cov qog.
Hypothalamus yog dab tsi?
Hypothalamus yog ib lub qog loj almond nyob hauv qab lub thalamus thiab tsuas yog saum lub paj hlwb. Tag nrho cov vertebrates lub hlwb muaj ib tug hypothalamus. Hypothalamus yog ib feem ntawm limbic system thiab muaj ntau lub nuclei me me nrog ntau yam haujlwm. Lub luag haujlwm tseem ceeb ntawm hypothalamus yog tswj hwm homeostasis hauv lub cev. Nws secretes 'tso cov tshuaj hormones' thiab 'inhibiting cov tshuaj hormones,' uas txhawb los yog inhibit zus tau tej cov tshuaj hormones nyob rau hauv lub anterior pituitary. Ib pawg tshwj xeeb neuron hu ua neurosecretory cells muaj nyob hauv hypothalamus. Lawv tsim cov tshuaj hormones hu ua antidiuretic hormone (ADH) thiab oxytocin (OXT). Cov tshuaj hormones no tom qab thauj mus rau pituitary, qhov chaw lawv khaws cia rau tom qab tso tawm.
Daim duab 01: Hypothalamus
Lub hypothalamus tswj qee cov txheej txheem metabolic thiab lwm yam dej num ntawm lub paj hlwb autonomic. Nws synthesizes thiab secretes tej yam neurohormones hu ua tso cov tshuaj hormones los yog hypothalamic cov tshuaj hormones. Cov tshuaj no, nyob rau hauv lem, txhawb los yog inhibit qhov tso tawm ntawm cov tshuaj hormones los ntawm lub caj pas pituitary. Tsis tas li ntawd, lub hypothalamus tswj qhov kub ntawm lub cev thiab kev tshaib kev nqhis. Ntxiv rau qhov ntawd, hypothalamus tseem tswj hwm qhov tseem ceeb ntawm kev ua niam txiv thiab kev coj cwj pwm, nqhis dej, qaug zog, pw tsaug zog, thiab circadian rhythms.
Pituitary Gland yog dab tsi?
Pituitary caj pas yog ib lub qog me me thiab liab-grey lub cev txuas nrog lub hypothalamus uas khaws cov tshuaj hormones los ntawm hypothalamus thiab tso rau hauv cov hlab ntsha. Lub caj pas pituitary muaj ib qho anterior lobe thiab lub lobe tom qab. Txhua lub lobes no muaj cov haujlwm sib txawv. Lub lobe anterior secretes cov tshuaj hormones uas tswj ntau yam ntawm lub cev ua haujlwm. Lub anterior pituitary lobe muaj tsib hom hlwb (somatotrophs, gonadotrophs, lactotrophs, corticotrophs, thiab thyrotrophs) uas tso tawm xya cov tshuaj hormones, suav nrog tib neeg kev loj hlob hormone (hGH), thyroid-stimulating hormone (TSH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), adrenocorticotropic hormone (ACTH) thiab melanocyte-stimulating hormone (MSH). Lub qab lobe khw muag khoom thiab tso tawm tsuas yog ob hom tshuaj hu ua oxytocin thiab antidiuretic hormone (ADH) lossis vasopressin.
Daim duab 02: Pituitary Gland
Lub luag haujlwm tseem ceeb ntawm lub caj pas pituitary yog tsim thiab tso tawm ntau cov tshuaj hormones uas pab tib neeg lub cev ua haujlwm tseem ceeb, suav nrog kev loj hlob, metabolism, kev yug me nyuam, teb rau kev ntxhov siab lossis kev raug mob, lactation, dej thiab sodium sib npaug, thiab kev ua haujlwm thiab kev yug menyuam.
Dab tsi zoo sib xws ntawm Hypothalamus thiab Pituitary Gland?
- Hypothalamus thiab pituitary caj pas complex yog qhov chaw hais kom ua ntawm tib neeg endocrine system.
- Ob lub qog nyob hauv lub hlwb.
- Cov qog no txuas rau ib leeg.
- Kev ua haujlwm tsis zoo ntawm ob lub qog yog lub luag haujlwm rau ntau yam kabmob.
Qhov txawv ntawm Hypothalamus thiab Pituitary Gland yog dab tsi?
Hypothalamus yog ib lub qog almond-loj nyob hauv qab thalamus thiab tso tawm cov tshuaj hormones thiab inhibiting cov tshuaj hormones uas txhawb lossis inhibit tsim cov tshuaj hormones nyob rau hauv lub pituitary anterior pituitary, thaum lub caj pas pituitary yog ib tug txiv laum huab xeeb caj pas txuas nrog lub hypothalamus thiab khaws cov tshuaj hormones los ntawm hypothalamus thiab tso tawm rau hauv cov hlab ntsha. Qhov no yog qhov sib txawv tseem ceeb ntawm hypothalamus thiab pituitary caj pas.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm hypothalamus thiab pituitary caj pas.
Summary – Hypothalamus vs Pituitary Gland
Hypothalamus thiab pituitary caj pas complex yog qhov chaw hais kom ua ntawm tib neeg endocrine system. Hypothalamus yog almond-loj qog uas nyob hauv qab lub thalamus. Nws secretes tso cov tshuaj hormones thiab inhibiting cov tshuaj hormones uas txhawb los yog inhibit zus tau tej cov tshuaj hormones nyob rau hauv lub anterior pituitary. Pituitary caj pas yog ib lub qog me me uas txuas rau lub hypothalamus thiab khaws cov tshuaj hormones los ntawm hypothalamus thiab tso tawm rau hauv cov hlab ntsha. Qhov no qhia txog qhov sib txawv ntawm hypothalamus thiab pituitary caj pas.
