We'll be glad to check your answer. Your text materials probably explain this.

SMOOTH MUSCLE

To determine which of the options is NOT a type of muscle, we need to understand the different types of muscles.

Let's break down each option:

A. Skeletal: Skeletal muscle is attached to bones and is responsible for voluntary movements.

B. Long: "Long" is not a recognized type of muscle. This option is likely incorrect.

C. Smooth: Smooth muscle is found in the walls of hollow organs, such as the intestines and blood vessels. It is responsible for involuntary movements.

D. Cardiac: Cardiac muscle is found in the heart and is responsible for involuntary contractions that pump blood.

Based on this information, it appears that option B, "Long," is not a recognized type of muscle. Therefore, the answer is B.
