Question

Which of the following type of muscle fibers are supplied with both central and autonomic nervous system and are not under the control of the will of the organism, have a rich blood supply and have the property of contraction even when they are isolated from the body temporarily?

• A. Single unit smooth muscle
• B. Multi unit smooth muscle
• C. Involuntary striated muscle
• D. All of these

Answer 1

The correct option is C Involuntary striated muscle

Cardiac muscles are the special types of muscles that show striations but they are not under the will of the organism. These are also called involuntary striated muscles because of this reason. They have rich blood supply as they have to perform the contraction regularly for the heart. They show the property of contraction even when they are isolated from the body temporarily. They are supplied with both the central and autonomic nervous system that regulate the heartbeat.

Hence, the correct answer is 'Involuntary Striated Muscles'.
