Question

A non-striated muscle is also called as

• A. Cardiac muscles.
• B. Skeletal muscle.
• C. Voluntary muscle.
• D. Involuntary muscle.

Answer 1

The correct option is D

Involuntary muscle.

The correct option is D.

Explanation for the correct option:

1. Muscle tissues can be found in all regions of the body.
2. They aid in motility and mobility.
3. These are classified as striated, non-striated, or cardiac based on their structure, location, and functions.
4. Non-striated muscles are smooth and devoid of striations.
5. Found in the hollows of internal organs such as the stomach, intestines, and urine bladder, among other places.
6. They are also known as involuntary muscles because their activation is not under the control of the human.

Explanation for the incorrect options:

Option A:

1. The cardiac muscles are involuntary in function, meaning they can't be controlled by humans, and they're engaged in the heart's constant rhythmic contraction and relaxation.
2. Cardiomyocytes are uninucleate (single nucleus) heart muscle cells that are cylindrical, elongated, striated, and branching.
3. If the cardiac muscles are injured, they have no ability to regenerate.

Option B:

1. A skeletal muscle is a voluntary muscle that is connected to the bones by tendons.
2. To allow agility in movement, they are striated and constructed from flexible muscle fibers.
3. The system is critical because it supports the body's weight and keeps its structure intact.

Option C:

1. A voluntary muscle, like the ones in the arms and legs, is one that you choose to move rather than one that moves automatically, like the heart.
2. Muscle is the connective tissue that allows animals to move. The term "voluntary" refers to one's own free will or decision.

Final answer: A non-striated muscle is also called as involuntary muscle.
