When you bend your arm at the elbow and feel your biceps your upper arm muscle contracts.👏👏
Cardiac Muscle tissue =)
Skeletal muscle fibers differ from typical cells in that these muscle fibers have many nuclei. The skeletal muscle store calcium ions in the sarcoplasmic reticulum.
Voluntary muscles are muscles you consciously think about moving, so stuff like Biceps, triceps, that kind of muscle.
There are the Triceps that have 3 muscle bodies and there are the Deltoids that has 3 muscle bodies as well.
I think it is the sacrolemma.
No it is not true, the antagonist muscle to the biceps is the triceps. You have to think of what muscles will have to release in order to allow contraction, another example would be when the quadriceps contract, your hamstrings must release otherwise the work of the muscles would contradict one another.
almost every muscle in your body moves when you breath weird huh

"bi" means 2. the bicep muscle consists of 2 separate muscles. I think it comes from greek or latin.
Most muscles in the body have "counterparts", one pulls and your leg curls up, the other pulls and the leg straightens. They would be on opposite sides of your leg. The "biceps" are the upper arm top muscle, and the tri-ceps (I think) is the upper arm bottom muscle. They work in conjunction to let you 'curl a barbell'' or do a chin-up.
triceps brachii, biceps brachii, pectoralis major, deltoid, there are many more but i feel these are the common ones known. ---------------------------------------------------------Recommend me if u like this.....
Voluntary means that it is under your conscious control - you think about moving the muscle and it moves. Some examples would be your arm and leg muscles (biceps, triceps, quadriceps) and your tongue.
