the jaw

Expert Solution
Step 1

Muscle is a soft tissue like structure which is primarily responsible for the movement in the body. The muscle tissue can be categorized on the basis of their structure and function into three categories: the skeletal muscle, the smooth muscle and the cardiac muscle. The skeletal muscles are the voluntary muscles which are attached to the bones and are responsible for locomotion, formation of facial expression and maintenance of postures. The smooth muscles are involuntary muscles located at the walls of major organs and tracts and are responsible for the internal movements of the organ. The cardiac muscle tissues are also involuntary muscles which typically form the heart. The muscle tissue is primarily responsible for pumping of heart causing blood to flow through its chambers.
