Question

Assign each characteristic to the appropriate type of muscle.

1) Skeletal muscle
2) Cardiac muscle
3) Smooth muscle

Answer 1

Skeletal muscle controls voluntary movement and has a striated pattern, cardiac muscle involuntarily contracts the heart with a striated pattern and interconnected cells, and smooth muscle manages involuntary functions in internal organs without a striated pattern.

Step-by-step explanation:

Skeletal muscle is usually attached to bones and is responsible for voluntary movements. Skeletal muscles are attached to bones and help with voluntary movements. They are striated and appear striped under a microscope. An example of skeletal muscle is the bicep in the upper arm. It is characterized by a striated appearance under a microscope due to its organized sarcomeres, is multinucleated, and has a fast contraction speed.

Cardiac muscle is found only in the heart and is responsible for pumping blood throughout the circulatory system; it is involuntary, striated, and has intercalated discs which allow the cells to contract in unison. Smooth muscle lines internal organs such as the stomach, intestines, and blood vessels. It is not striated, is usually involuntarily controlled, and has a single nucleus in each cell.
