Sinus tachycardia can be the most probable condition which results into high heart rate above 105 beats/minute. This problem is not very serious and is treatable.
<h3>What is Sinus tachycardia?</h3>
Sinus tachycardia is a type of irregular heartbeat which is characterized by a faster than the normal heart rhythm. The heart's sinus node generates electrical impulses which travels through the heart muscle that causes the heart to beat. A normal sinus rhythm has an average heart rate of the range between 60 and 100 beats/minute.
Treatment is not necessary for sinus tachycardia as it is not a very serious issue. However, if an underlying condition is causing these symptoms, it needs to be treated on time. Treatments for sinus tachycardia include medications such as beta-blockers or calcium channel blockers which can lower the heart rate.

Reduced blood volume leads to collapsing vessels, reduced pressure, and subsequently reduced perfusion pressure. The cardiovascular system combats low blood volume by constricting blood vessels until the body reaches a blood pressure that restores proper perfusion pressure.
Answer:
1. dendrite = directs impulses toward the soma.
2. axon = conducts impulses toward the synaptic terminal.
3. perikaryon = region surrounding nucleus.
4. collateral branches = main branches of an axon.
5. synaptic terminal = enlarged end of an axon.
6. synaptic vesicles = contains neurotransmitters.
7. axon hillock = connects the cell body and axon.
8. Nissl bodies = clusters of RER and free ribosomes.
9. telodendria = fine branches of an axon.
10. myelinated internode = part of axon covered by Schwann cell.
11. neurilemma = Schwann cell's plasma membrane.
12. axolemma = membrane of the axon.
13. astrocyte = Forms the blood-brain barrier.
14. cell body = soma.
Answer:
Atropine is highly potent antagonist of G-Class proteins of receptors termed as muscarinic acetylcholine receptors. Atropine blocks the action of these receptors and suppress the effects caused by parasympathetic nervous system. These complications of Atropine may lead to Tachycardia in patients administrated with atropine.
