Adrenergic neurons zais norepinephrine thiab pom muaj nyob hauv ob qho tib si hauv nruab nrab thiab lub cev tsis muaj zog. Nyob rau hauv autonomic fibers , adrenergic cov neurons tshwj xeeb tshaj yog pom hauv postganglionic neurons ntawm kev mob siab rau lub paj hlwb.
Ua qhov no hauv kev txiav txim siab, cov fibers twg yog adrenergic?
Ib adrenergic paj hlwb fiber ntau yog lub paj hlwb uas tus neeg xa xov paj yog adrenaline (epinephrine), noradrenaline lossis dopamine. Cov neurotransmitters no tau tso tawm ntawm qhov chaw hu ua synapse, uas yog lub ntsiab lus sib txuas ntawm lub axon ntawm ib lub xovtooj ntawm tes thiab dendrite ntawm lwm tus.
Ib sab saum toj no, dab tsi ua cholinergic fibers tso? Zoo siab cholinergic ua kom tso tawm ACh uas khi rau muscarinic receptors, uas txhawb kev tawm hws thiab nthuav cov hlab ntsha hauv daim tawv nqaij.
Kuj Paub, dab tsi yog adrenergic thiab cholinergic fibers?
1. Adrenergic koom nrog kev siv cov neurotransmitters epinephrine thiab norepinehprine thaum cholinergic koom nrog acetylcholine . 2. Adrenergic hu ua txoj kab kev khuv leej (SNS) thaum cholinergic hu ua kab parasympathetic (PNS).
Cov tshuaj adrenergic siv rau dab tsi?
Cov tshuaj Adrenergic muaj ntau siv . Lawv yog siv rau nce lub plawv tawm, nce ntshav siab, thiab nce cov zis ntws raws li ib feem ntawm kev kho mob poob siab. Adrenergics yog thiab siv ua lub plawv stimulants.

Sharpey cov fibers nyob qhov twg?
Lawv yog ib feem ntawm txheej txheej fibrous ntawm periosteum, nkag mus rau sab nrauv thiab interstitial lamellae ntawm cov pob txha. Sharpey cov fibers kuj tseem siv los txuas cov leeg nqaij rau periosteum ntawm cov pob txha los ntawm kev koom ua ke nrog cov fibrous periosteum thiab cov pob txha hauv qab ib yam
