Question

The tissue that has a central nucleus, tapered at both ends, and control movement that is not under conscious control is

• A. Striated muscle
• B. Smooth muscle
• C. Cardiac muscle
• D. Skeletal muscle

Answer 1

The correct option is B

Smooth muscle

The correct option is B:

Explanation of correct option:

1. Smooth muscle which is also known as non-striated muscle contains a long, narrow, and spindle-shaped and both ends are tapered.
2. They are uninucleated i.e. only one nucleus is present in the center.
3. They are involuntary because their actions are controlled by the autonomic nervous system.

Explanation of incorrect option:

Option A:

1. Striated muscles contain single, elongated, and unbranched muscle fibers.
2. They are multinucleated and voluntary in action as they work according to our wishes (their actions are controlled by the nervous system).

Option C:

1. Cardiac muscle contains cylindrical, elongated, and branched muscle fibers.
2. In cardiac muscle one or two nuclei are present in between the two intercalated discs.
3. They are involuntary (control movements that are not under conscious control) in action.

Option D:

1. Skeletal muscle also known as the Striated muscles contains the single, elongated, and unbranched muscle fibers.
2. They are multinucleated and voluntary in action as they work according to our wishes.

Final Answer: Thus, The tissue that has a central nucleus, tapered at both ends, and control movement that is not under conscious control is smooth muscle.
