Muscle is made up of proteins called actin and myosin, which the actual percentage of each may differ depending on the type of muscle. Muscle is made up of proteins called actin and myosin. Depending on the type of muscle (skeletal muscle, smooth muscle, or cardiac muscle), the actual str...
These stripes are called striations. Skeletal muscles usually move because the brain has sent a conscious message to them telling them what to do. This is called voluntary movement. Another type of muscle is smooth muscle. Unlike skeletal muscle, smooth muscle does not have s...
The cardiac muscle is the heart, responsible for pumping blood throughout the body. It is made up of cardiac muscle and is the only place in the body where such muscle is found. All the other muscles in the body are composed of either skeletal muscle or smooth muscle. The most muscular...
You may be surprised to know that you have up to 840 different muscles in your body. They come in different types: cardiac muscles, smooth muscles and skeletal muscles. Cardiac muscle forms the wall of the heart, and smooth muscle is inside blood vessels, the uterus, the walls of the int...

Muscle spindles are sensorimotor organs in skeletal muscle. Each muscle spindle is made up of three to five specialized muscle...
Skeletal muscle is striated muscle tissue attached to bones. Each skeletal muscle is attached to a bone on one end, and stretches...
All of the extensor muscles of the human body are muscles of the striated type. They are formed from a mass of parallel fibers called myofibers. These myofibers are built up of many long, cylindrical cells, each of which has multiple nuclei. In the structure of an extensor muscle, the myo...
Stimulating frequencies around 30 Hz might be higher than is ideal, producing muscular degeneration because of long-term imbalances of energy demand and supply. Using seven skeletal muscle ventricles made of electrically conditioned latissimus dorsi muscle, a 10-min fatigue test was performed with ...
