What muscles are both voluntary and involuntary?
By applying these classifications three muscle types can be described; skeletal, cardiac and smooth. Skeletal muscle is voluntary and striated, cardiac muscle is involuntary and straited and smooth muscle is involuntary and non-striated.
What is the difference between voluntary and involuntary actions?
Answer: Voluntary action – Actions which are controlled by “the Cerebrum (Fore brain)” are called voluntary actions. Theses actions are slow actions which can regulate by muscles of the body. … Involuntary action – Actions that are controlled by “the Hind brain and the Spinal cord” are called Involuntary actions.

What are the 3 types of muscle tissue?
The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control.
What types of muscles that Cannot be controlled?
D. There are three different types of muscles in the human body: smooth muscles, cardiac muscles, and skeletal muscles. Of these, we can only voluntarily control the skeletal muscles. We do not have control over smooth muscles and cardiac muscles and they work without our conscious effort.
What is the difference between striated and Nonstriated muscle?
Striated Muscle: The muscle which shows cross striations are called striated muscles or striped muscles. … So, they are also called voluntary muscles. Non striated muscle: The muscle which show no cross striations are called non striated muscles or unstriped muscles. They look smooth, hence are called smooth muscles.
What can muscle cells do that other cells Cannot?
Muscles are organs composed mainly of muscle cells, which are also called muscle fibers. Each muscle fiber is a very long, thin cell that can do something no other cell can do. It can contract, or shorten. Muscle contractions are responsible for virtually all the movements of the body, both inside and out.
