TYPES, LOCATIONS AND FUNCTION OF MUSCLES.
There are three types of muscles, located at various parts of the body.
In order to function all use energy in form of ATP.
These include smooth, skeletal and cardiac muscles.
Smooth Muscle (Involuntary Muscles)
These are spindle-shaped and contain filaments with myofibrils.
Each muscle is bound by plasma membrane.
They are found lining internal organs such as alimentary canal, bladder, and blood vessels.
They are controlled by involuntary part of the nervous system.
