Feem ntau txaus siab postganglionic fibers tso tawm norepinephrine. Raws li tau hais dhau los, cov hlwb ntawm adrenal medulla raug txiav txim siab hloov kho txaus siab postganglionic neurons . Hloov cov neurotransmitter, cov hlwb no tso cov tshuaj hormones rau hauv cov ntshav.
Tib neeg kuj nug, thaj tsam twg ntawm lub hlwb tswj cov txiv neej lossis poj niam kev coj tus cwj pwm los ntawm kev tswj ncaj qha tso tawm gonadotropins los ntawm lub caj pas pituitary?
Lub hypothalamus, lub hauv paus lub paj hlwb cheeb tsam uas yog lub luag haujlwm rau tswj ntawm kev yug me nyuam , tswj pituitary hormone synthesis thiab tso tawm . Gonadotropin - tso tawm hormone (GnRH) lossis luteinizing hormone (LH)- tso tawm Cov tshuaj hormones yog ib qho pivotal hypothalamic neuropeptide uas tswj nqaj qaum kev yug me nyuam (1).
Qhov thib ob, muaj pes tsawg lo lus nug nyob ntawm Bio 30 daim ntawv kawm tiav? 20 tshooj hauv Alberta Education Diploma - Biology 30 : Exam Prep & Study Guide. Tshawb xyuas koj qhov kev paub ntawm chav kawm no nrog 50- lus nug xyaum xeem.
Ntxiv mus, qhov kev faib tawm ntawm lub paj hlwb yog lub luag haujlwm ncaj qha rau cov lus teb rau lub cev kom ntshai?
Parasympathetic Nervous System . Lub parasympathetic lub paj hlwb yog a kev faib ntawm autonomic lub paj hlwb (ANS).
Dab tsi ua rau kev tso tawm ntawm gonadotropin tso cov tshuaj hormones?
Paub daws teeb. Gonadotropin tso cov tshuaj hormones ( GnRH ) yog zais los ntawm hypothalamus thiab txhawb gonadotropic hlwb nyob rau hauv lub anterior pituitary caj pas mus rau tso tawm luteinizing ua tshuaj hormone thiab follicle- stimulating hormone , uas nyob rau hauv lem tswj lub gametogenic thiab steroidogenic zog ntawm gonads nyob rau hauv txiv neej thiab poj niam.

Qhov twg ntawm cov hauv qab no yog qhov muaj peev xwm tshwm sim tshwm sim ntawm kev tswj hwm procainamide?
Muaj ntau cov kev mob tshwm sim tom qab induction ntawm procainamide. Cov kev tsis zoo no yog ventricular dysrhythmia, bradycardia, hypotension thiab poob siab. Cov kev phom sij tshwm sim ntau dua yog tias cov koob tshuaj txhua hnub tau nce. Procainamide kuj tseem tuaj yeem ua rau kub cev tshuaj thiab lwm yam kev ua xua
Kev faib tawm ntawm lub cev tsis muaj zog lub cev siv lub zog li cas?
Lub cev tsis muaj zog tswj hwm cov qog thiab cov leeg ntawm cov kabmob sab hauv. Lub siab lub ntsws ua rau lub cev muaj zog thiab siv zog ntxiv. Nws yog lub luag haujlwm rau peb kev sib ntaus thiab kev teb dav hlau. Lub paj hlwb parasympathetic ua rau lub cev so thiab txuag lub zog
Qhov sib txawv ntawm bilirubin ncaj qha thiab bilirubin ncaj qha yog dab tsi?
Abb. Nco tseg: Conjugated bilirubin feem ntau tsis raug hu ua 'bilirubin ncaj qha' thiab unconjugated bilirubin tsis raug hu ua 'indirect bilirubin'. Ncaj thiab ncaj qha hais txog qhov sib xyaw ntsuas lossis kuaj pom hauv kev daws teeb meem. Indirect bilirubin yog rog-soluble thiab ncaj qha bilirubin yog dej-soluble

AKA pob txuv vulgaris- Cov teeb meem ntawm daim tawv nqaij ua rau mob ntev ntawm cov qog sebaceous los ntawm khaws cia tso zis thiab Propionbacterium acnes, lub sijhawm tshawb fawb rau cov kab mob pob txuv. Qhov mob ntawm daim tawv nqaij qhuav, tawv nqaij vim tsis muaj lossis tsis muaj sebum uas tshwm sim los ntawm cov laus thiab los ntawm qhov txias
Dab tsi yog qhov sib txawv ntawm lub cev muaj zog loj neuron thiab qis lub cev neuron?
Lub cev muaj zog neurons pib hauv thaj tsam lub cev ntawm lub paj hlwb. Ntawm qhov tod tes, qis lub cev muaj zog neurons tau txais kev cuam tshuam los ntawm lub cev muaj zog neurons thiab txuas tus txha caj qaum thiab lub paj hlwb mus rau cov leeg nqaij. Lawv yog cov hlab ntsha cranial thiab spinal
