Both. Organs are a group of cells devoted to a single and common purpose, which muscles are, and are composed of tissues.

Sarcomeres contain myofilaments which consist of actin (thin) and Myosin (thick).

This is the fascia, which is actually composed of three separate levels. There is one layer that wraps around each muscle fiber, another layer that wraps around each muscle bundle and then a final layer that wraps around the whole muscle.

cardiac muscle tissue

Technically the muscular system refers to all three types of muscle tissues; skeletal, cardiac, and smooth. However, the cardiac and smooth muscles can be considered functional units of other systems as well. In the case of the cardiac muscle it would be the cardiovascular system and in the case of smooth muscle it would most likely be the digestive system. I say most likely because the largest amount of smooth muscle is associated with the digestive system and the gastrointestinal tract, but it is also a part of other systems and organs. Here a a few examples: muscular lining of arterioles in the cardiovascular system and the muscular lining of the urinary bladder in the excretory system.

one would be the amount of contractile strength that results from a muscle contraction.

The truth is that muscles give your body movement.

* It depends on the individual woman. I prefer lean, mean and slightly muscular (not so muscular their veins are popping out) men, but even when younger I went for the guys that were a little shy, interesting, had a good sense of humor and treated me like a lady and if the chemistry worked then it was great. I dated male models, a life guard and found they were so into themselves the dates with them were boring and I dumped them. Men that are very muscular spend hours getting this way and they often will cheat with steroids. Nope, give me a guy that keeps his health up without being too into himself any day. Young male teens sometimes find that they don't think girls are attracted to them and instead of working on their personality they get mixed messages and work out like crazy and are under the delusion that muscles will get them the girls they are interested in. Not true! * Women like muscles more than they care to admit. I know, I was a walking young muscle once. Go to a night club and show off your arms and chest a bit and after the women have a drink or two they are just as bad as us men. They want to hang off those arms. However, don't mistake physical attraction with male arrogance. Although it is a fine line, women like confidence, not arrogance.

a large triangular muscle covering the joint of the shoulder, the action of which raises the arm away from the side of the body.

Yes.

The cerebellum is the part of the brain that coordinates complex muscular movements. This part of the brain also communicates with the rest of the central nervous system and helps maintain posture.

nerve cells transfer data and feelings such as pain to the bain to be processed. other cells are practicly independent and use their own nucilus to do the processing, however much there may be.

Stretching causes you to breathe deeply bringing oxygen to your brain, in effect waking you up. Secondly, stretching releases the physical form of stress that is stored in your muscles. Storing that tension takes constant work by your muscles. Relieving that work frees up energy. Lastly, stretching helps your body remove toxins from your tissues.
