Norepinephrine acts on the heart by _________
Westkost [7]

Answer:

The correct option is : a. causing threshold to be reached more quickly      

Explanation:

Norepinephrine, also known as noradrenalin, is an organic compound, which belongs to the catecholamine family. It acts as a hormone and a neurotransmitter in the brain and the body and also impacts the heart.

It is one of the hormones secreted by the adrenal medulla. Norepinephrine is a part of the fight-or-flight mechanism of the body. It acts by binding to the β-1 receptors and opens the chemical or ligand gated calcium and sodium ion channels. Therefore, <u>it causes the threshold to be reached faster </u>by increasing the rate of depolarization and thus causes heart arrhythmia.

Therefore, <u>Norepinephrine acts on the heart by </u><u>causing threshold to be reached faster.</u>

<h3>What is vaginal delivery ?</h3>

The birth of young through the vagina occurs during a vaginal delivery in mammals. It is the method of birthing that is most widely used. Compared to Caesarean sections, it is regarded as the preferred mode of delivery because of its reduced morbidity and mortality rates.

  • A spontaneous vaginal delivery occurs when the baby is pulled out of the body naturally without the assistance of medical personnel or tools. This happens following a pregnant woman's labour. Her cervix enlarges or dilates during labour by at least 10 cm.

  • For the person giving birth, vaginal delivery has the advantages: less time spent recovering. Lactation starts earlier. Future pregnancy difficulties are less likely.
