When studying under miscroscope part of the muscle, what the researcher is most likely looking at is sarcolemma.

Explanation:

The sarcolemma corresponds to the name of the specialized cell membrane of the muscle fiber, forming an assembly between the plasma membrane and the reticular and external laminae. In its composition, besides the lipids, there are polysaccharides and collagen fibrils.

This myocyte cell membrane not only forms the external cover of the muscle cell, but is also capable of penetrating the sarcoplasm (cytoplasm) and constituting a trabecular formation, called T-tubules, with participation in the process of fiber contraction.

Regarding other options:

Sarcoplasmic reticulum is the smooth endoplasmic reticulum of the muscle cell. Myofibrils are a collection of muscle cells. Fascicle fibers is a set of myofibrils.

1. cold turkey (no outside ). about 90% of people who try to quit smoking do it without outside support -- no aids, therapy, or medicine. although most people try to quit this way, it's not the most successful method. only about 5% to 7% are able to quit on their own.

2. behavioral therapy. this involves working with a counselor to find ways not to smoke. together, you'll find your triggers (such as emotions or situations that make you want to smoke) and make a plan to get through the cravings.

3. nicotine replacement therapy. there are several types, including nicotine gum, patches, inhalers, sprays, and lozenges. they work by giving you nicotine without the use of tobacco. you may be more likely to quit with nicotine replacement therapy, but it works best when you use it with behavioral therapy and lots of support from friends and family. and remember that the goal is to end your addiction to nicotine, not simply to quit using tobacco.
