Final answer:
Skeletal muscles are primarily responsible for creating bodily movement. They also help maintain posture, regulate body temperature, and protect internal organs.
Step-by-step explanation:
The primary function of skeletal muscles is to create bodily movement. They contract and cause movement in the body, allowing us to walk, run, and perform various actions. However, skeletal muscles do have other important functions as well. They help maintain posture by resisting gravity, regulate body temperature by generating heat, and protect internal organs by acting as a barrier against external trauma.
