Question:

Which of the following is not a feature of skeletal muscles?

Options:

1. Are associated with skeletal components of the body
2. Striped appearance
3. Voluntary control
4. Transportation of food through digestive tract

Solution:

Transportation of food through the digestive tract is not a feature of skeletal muscles. Skeletal muscles are a type of muscle tissue that are attached to bones and provide movement and support for the body. They have a striped or striated appearance due to the organization of the contractile proteins, actin, and myosin, within the muscle fibers. Skeletal muscles are under voluntary control, meaning they can be consciously contracted and relaxed to produce movement. However, they are not involved in the transportation of food through the digestive tract, which is primarily the role of smooth muscle tissue in the walls of the digestive organs.
