Involuntary Muscles
Involuntary muscles are striated and branched in the case of the heart muscle. The action of involuntary muscles is mainly regulated by the body’s autonomic nervous system. These involuntary muscles include smooth muscle and cardiac muscle.
- Smooth muscles are found in the lining of the intestines, stomach, uterus, and blood vessels. These muscles help push food molecules along the length of the digestive tract, control the diameter of blood vessels, and contract the uterus during childbirth.
- Cardiac muscle is unique and is found only in the heart. These muscles keep the heart beating by maintaining proper blood circulation throughout the body.
Similarities Between Voluntary and Involuntary Muscles
- Voluntary and involuntary muscles are two components of the musculature of the body.
- Voluntary and involuntary muscles are composed of muscle cells.
- Voluntary and involuntary muscles are under the control of the nervous system
Difference Between Voluntary and Involuntary Muscles
Voluntary, involuntary, and myocardium are three types of muscles found in animals. Skeletal muscles are considered voluntary muscles while smooth muscles are considered involuntary muscles. Voluntary muscles are attached to bones and help in the movement and movement of various parts of the animal’s body. The involuntary muscles are found in the walls of the hollow organs and control the internal movements of the organs.
Internal organs help move fluids and food through the digestive system. The key difference between voluntary and involuntary muscles is that voluntary muscles are innervated by the somatic nervous system whereas involuntary muscles are innervated by the autonomic nervous system.
