How many, types of muscles occur in the body of a vertebrate? Briefly describe the structure of a striated muscle.

Answer 1

• There are three types of muscle occurs in the body of a vertebrate are skeletal or striated, cardiac, and smooth.
• Muscle action can be classified as being either voluntary or involuntary.
• Striated muscle tissue is a muscle tissue that features repeating functional units called sarcomeres, in contrast with smooth muscle tissue which does not.
• The presence of sarcomeres manifests as a series of bands visible along the muscle fibres, which is responsible for the striated appearance observed in microscopic images of this tissue.
• There are 3 types of striated muscles:

1. Pharyngeal muscle (embryologically different from skeletal muscle)
2. Cardiac muscle (heart muscle)
3. Skeletal muscle.
