Question

Which of the following is voluntarily controlled?
(A) Blood
(B) Smooth muscle
(C) Striated muscle
(D) Adipose tissue

Answer 1

Hint:The muscles or the organs are either voluntarily or involuntarily controlled by the nervous system of the human. If the movement is controlled with the consciousness of the individual, it is known as voluntarily controlled and if it is not, involuntary controlled.

Complete answer:
While considering the given options, the blood is the fluid with several cells like RBC, WBC and platelets. This was transmitted by the pumping of the heart to all parts of the body. It does not take place with the consciousness of the person. And hence it is involuntary in nature. The smooth muscles are the uninucleate muscles which are spindle shaped and unbranched.

They take place without any consciousness of the individual and so they are involuntary. Striated muscles are located in the skeleton like pectoral muscles, diaphragm, the quadriceps, triceps muscles etc. These are voluntary muscles since they take place with the human conscious. The adipose tissue consists of the fats that are located in the skin and the internal organs like the liver. They are under the involuntary control.

Thus the correct answer is option (C).

Note:The examples of the smooth vessels are the muscles in the hollow organs like stomach, intestine, arteries, veins, respiratory tracts, urinary tracts and the muscles in the reproductive system. The adipose tissue in the form burns into the energy when there is no glucose in the body.
