Question

Describe the nucleus position for each of these muscle types

Answer 1

Answer:

1. Skeletal muscle nucleus position- Periphery of the cell

2. Smooth muscle nucleus position- At the center of the cell

Explanation:

The skeletal muscles are elongated and are tubular in shape. 40% of our body mass is made up of skeletal muscles. They are attached to the bones and help in movement. They consists of multiple nuclei and the nuclei are located at the periphery of the cell.

The smooth muscles are spindle shaped. They are wide in the middle and narrow at the end points. They are responsible for involuntary movements in the internal organs. These types of muscles have a single centrally located nucleus.

Thus,

1. Skeletal muscle nucleus position- Periphery of the cell

2. Smooth muscle nucleus position- At the center of the cell
