Summary of the Article:
There are two major classifications of muscle: smooth and striated. Skeletal as well as cardiac muscle fall under the category of striated. Muscles are metabolically dynamic tissues and receive plentiful blood flow.All muscles can be excited, in that they respond to stimuli outside or inside the body. Both neuron stimulation and chemical stimulation affects the response of the cells.
Skeletal Muscle:
Skeletal muscle is voluntary because it is subject to control by the nervous system. Most movement requires skeletal muscle.

Skeletal muscle fibers |
Skeletal muscle is made of numerous fibers grouped together. Fibers can be grouped into larger groups, which are then grouped into even larger groups and attached to bones by tendons.
Smooth Muscle:
Smooth muscle is non-striated and found in all organ systems. They are involuntary muscles and help with processes like digestion and sometimes are present in large blood vessels.

Smooth muscle fibers are largest in the center. |
