Which of these 2 chemicals would make the best muscle relaxant and why?

Question

Chemical A: binds and blocks acetylcholine receptors of muscle cells

Chemical B: floods the cytoplasm of muscle cells with calcium ions

Answer 1

I would say A.

If ACh receptors are blocked, then the action potential chain reaction is never started, the sarcolemma's terminal cisternae are never activated (and so PREVENTS the release of calcium ions).

The release of calcium ions is what opens the G actin active sites on the thin filament and allows the myosin heads to start tugging on them and causes tension in the muscle.

Answer 2

hey, im not 100 percent sure on this one, but i think if you flood the cytoplasm with calcium ions the muscles will contract and u want them to relax. so i would go with A. i think every muscle relaxant works with acetylcholine. to double check, do a search on Flexeril on webmd or any medical site. hope this helps

Answer 3

Flexaril is a great muscle relaxant. I have been taking it for quite some time with no problems. Someone on the list posted a few weeks ago that they spoke with their relative who is a doctor and he told them that Flexaril doesn't cause other problems and is not addictive.

Answer 4

Cholinesterses have inconvenient side effects like drooping of eye lids constriction of pupils,decreasing intestinal motility etc. Calcium ions perpetuate muscle contractions.

How It Works

Muscle relaxant medications relax muscles and may help reduce pain in people who have muscle spasms.
Why It Is Used

Muscle relaxant medications are used when muscle spasms develop because of pain caused by a herniated disc.

Valium is not recommended for use by pregnant women, older adults, or people with depression or a history of drug or alcohol addiction.


How Well It Works

Muscle relaxant medications are usually helpful for reducing the pain of muscle spasms. Muscle relaxants may help to relax muscle spasms caused by a herniated disc; however, muscle relaxants will not affect the herniated disc itself.

1 Side Effects


Side effects of muscle relaxant medications include:

* Drowsiness.
* Dry mouth.
* Likelihood of addiction with regular use of diazepam (Valium) and carisoprodol (such as Soma).
* Urinary retention.
