Question

Which of these are types of muscle?

Skeletal
Cardiac
Smooth
Endocrine
Respiratory

Answer 1

Skeletal, cardiac, and smooth are all types of muscles.

Main features of these three muscle types-

1. Skeletal Muscles: Fibers are striated, tubular, and multinucleated. These muscles are voluntary and are usually attached to the skeleton.
2. Cardiac Muscles: Fibers are striated, branched, and uninucleated. These muscles are involuntary and only cover the walls of the heart.
3. Smooth Muscles: Fibers are non-striated, spindle-shaped, and uninucleated. These muscles are involuntary and usually cover the walls of internal organs.
