Lub acetylcholine receptor (AChR) yog ib tug membrane protein uas khi rau cov neurotransmitter acetylcholine (Ach). Cov receptors no tuaj yeem muab faib ua ob hom tseem ceeb ntawm cov receptors, nicotinic tshuaj thiab muscarinic.
Tsis tas li ntawd, acetylcholine receptors nyob qhov twg?
Acetylcholine receptors tau pom nyob rau saum npoo ntawm cov leeg nqaij, mloog zoo nyob hauv qhov sib txuas ntawm cov paj hlwb thiab cov leeg nqaij.
acetylcholine receptor ua dab tsi? Nicotinic acetylcholine receptors , los yog nAChRs, yog receptor polypeptides uas teb rau cov neurotransmitter acetylcholine tshuaj . Nicotinic cov receptors kuj teb tshuaj raws li agonist nicotine. Lawv yog pom nyob rau hauv nruab nrab thiab peripheral paj hlwb, nqaij, thiab ntau lwm yam ntaub so ntswg ntawm ntau yam kab mob.
Ua raws li qhov xav tau, hom neurotransmitter yog acetylcholine?
Acetylcholine (ACh), thawj neurotransmitter puas tau raug txheeb xyuas, yog ib qho me me- molecule excitatory neurotransmitter nrog ntau yam kev paub ua haujlwm. Nyob rau hauv lub sympathetic thiab parasympathetic paj hlwb thiab ntawm tag nrho cov neuromuscular junctions, ACh yog siv los qhia cov leeg nqaij.
Dab tsi yog qhov txawv ntawm cholinergic receptors?
Muaj ob hom cholinergic receptors : cov nicotinic cov receptors thiab muscarinic receptors . Ob leeg cov receptors muaj nyob rau ntawm sympathetic thiab parasympathetic postganglionic fibers, thiab tseem nyob rau hauv lub hom phiaj. Txhua yam tau qhib los ntawm cov kab mob neurotransmitter acetylcholine tshuaj.

Yam twg ntawm cov hauv qab no yog tus yam ntxwv ntawm Qeb Kuv tus menyuam lub plawv dhia taug qab?
Qeb I: Ib txwm. Lub plawv dhia dhia hauv plab qhia tag nrho cov hauv qab no: Baseline FHR 110-160 BPM, nruab nrab FHR qhov sib txawv, accelerations yuav tam sim no los yog tsis tuaj, tsis lig los yog txawv txav decelerations, tej zaum yuav muaj thaum ntxov decelerations.

Yam 3 yam twg tau sau tseg txog kev ua pa?
Peb yam tseem ceeb uas yuav tsum tau sau tseg txog txhua lub plawv dhia yog Kev suav pa, Rhythm thiab Tus yam ntxwv ntawm kev ua pa. Vim li cas thiaj noj apical mem tes? Vim tias muaj mob, ua kom cov hlab ntshav khov, thiab lub plawv dhia tsis muaj zog lossis nrawm, koj yuav tsum tau siv lub plawv dhia
