What is the function of skeletal muscle in an animal?

Skeletal muscle plays a crucial role in the movement and support of an animal's body. This type of muscle is attached to bones and is responsible for voluntary movements, allowing the animal to perform a wide range of activities such as walking, running, jumping, and lifting. The contraction of skeletal muscles not only facilitates movement but also helps maintain posture and supports the body against gravity.

Additionally, through the coordinated action of multiple skeletal muscles, various complex movements can be executed, contributing to the overall agility and functionality of the animal. Muscles can either work in isolation or as part of a larger system to coordinate complex motor activities.

Other options refer to functions not associated with skeletal muscle: the heart in option A is controlled by cardiac muscle, digestion in option C is a function of smooth muscle in the digestive tract, and option D pertains to adipose tissue rather than muscle tissue. Therefore, the primary and definitive function of skeletal muscle aligns with movement and support.
