Question

The muscles involved in the movement of the arm are:
A Unstriped
B Striped
C Cardiac
D None of the above

Answer 1

Muscle is a type of contractile tissue that is organised into systems for increased efficiency. Muscle systems in humans are categorised based on their physical appearance and cell placement. Striated or skeletal muscles, cardiac muscles, and smooth or nonstriated muscles are the three types of muscles.

Complete answer:
Striated muscle tissue is made up of sarcomeres, which are repeating functional units. Sarcomeres are evident as a series of bands running along the muscle fibres, which accounts for the striated appearance seen in microscopic photographs of this tissue.
Involuntary muscles are those that are not striated. Involuntary movements include food movement in the alimentary canal and blood vessel contraction and relaxation. Smooth muscles is another name for it. Muscles found in the iris of the eye, the ureters, and the bronchi of the lungs, for example.
One of the three forms of muscle tissue in your body is cardiac muscle tissue. Skeletal muscle tissue and smooth muscle tissue are the other two categories. Cardiac muscle tissue can only be found in your heart, where it produces coordinated contractions that enable your heart to pump blood throughout your circulatory system.
The most widespread and widely distributed muscle tissue in the body is striated muscle, often known as skeletal muscle. It gives rise to all skeletal muscles, including the biceps. Voluntary muscle is striated muscle. The skeletal or striated muscle tissue is responsible for all conscious movements of the body, including arm, leg, face expressions, eye movements, and swallowing.

As a result, option B is the proper response.

Note: Humans can move and accomplish daily tasks thanks to skeletal muscles. They aid in the maintenance of posture and balance and play an important function in respiratory mechanics. They also safeguard the body's essential organs.
