Muscles are cylindrical, straighted and multinucleate but they would not be branched because there are no multiple bone makes one bone though there are such bones that are multiple but are fragments. There are branched cells like neuron.

The correct answer is 'D - Branched'.

Skeletal muscle, also known as striated muscle, is a type of muscle tissue that is attached to the bones and responsible for voluntary movements of the body. It is characterized by several features, including being cylindrical, striated, and multinucleated. However, it is not branched.

Explanation:

1. Cylindrical:
Skeletal muscle fibers have a cylindrical shape, meaning they are long and tube-like in structure. This shape allows for efficient contraction and relaxation of the muscle.

2. Striated:
Striated muscle refers to the presence of alternating light and dark bands, known as striations, that can be observed under a microscope. These striations are caused by the arrangement of contractile proteins within the muscle fibers, specifically actin and myosin. The striated appearance is responsible for the characteristic banding pattern seen in skeletal muscle.

3. Multinucleated:
Unlike most other cells in the body, skeletal muscle fibers are multinucleated, meaning they contain multiple nuclei. This is because during development, multiple myoblasts (precursor cells) fuse together to form a single muscle fiber. The presence of multiple nuclei allows for efficient control and maintenance of the large muscle fiber.

4. Not Branched:
Unlike cardiac muscle and some types of smooth muscle, skeletal muscle fibers are not branched. Branched muscle fibers are typically found in cardiac muscle, which forms the walls of the heart, and smooth muscle, which lines the walls of various organs. The lack of branching in skeletal muscle fibers allows for a more linear arrangement of muscle fibers, which contributes to the coordinated and synchronized movement of the skeletal system.

In summary, the features of skeletal muscle include being cylindrical, striated, and multinucleated, but it is not branched.
