Question

A student was asked to observe a slide of skeletal muscle fiber under the microscope. The correct diagrams(s) given below that resemble(s) the slide of skeletal muscle is/are

• A. Only B
• B. Only A
• C. Both A and C
• D. Only D

Answer 1

The correct option is D Only D

Skeletal muscles have the following features:

1. These are striated due to the presence of sarcomere.
2. These are unbranched
3. The cells are multinucleated
   
4. These are cylindrical in shape

These features are shown in image D.

Image A shows smooth muscles that are spindle-shaped and non-striated.

Image B shows cardiac muscles that are striated, branched and uni-nucleated.

Image C does not resemble any muscle. It is enucleated.

Image D shows the striated, multi-nucleated, unbranched fibers that are skeletal muscles.

Hence, the correct answer is 'D'
