muscles are made of what tissues
Muscle tissue functions mainly as a source of power and motion in the body. Muscles' main responsibility is for changing or maintaining posture, locomotion, and movement of internal organs. The human body has about 650 muscles, which make up approximately half our bodyweight. All muscles are basically made of the same material, a kind of elastic tissue; packages of stretchable fiber-like material, similar to what goes into making a rubber band. Each muscle is made of thousands, and sometimes tens of thousands of small musculus fibers. Each muscle fiber is about 40 mm in length and is made up of tiny strands of fibrils. Each muscle fiber is commanded by a nerve which makes it contract. How strong a muscle is depends mainly on how many fibers are present.

Muscle tissue, one of the four major tissue types, plays the vital role of providing movement and heat generation to the organs of the body. Within muscle tissue are three distinct groups of tissues: skeletal muscle, cardiac muscle, and smooth muscle. Each of these tissue groups is made of specialized cells that give the tissue its unique properties. Skeletal muscle is the most common and widely distributed muscle tissue in the body, making up around 40% of the bodyâs total mass. It forms all of the skeletal muscles, such as the biceps brachii and gluteus maximus, and is found in the eyes, throat, diaphragm, and anus....
