How is the muscular system related to the skin system?

The muscular system and the integumentary (skin) system are interconnected through their roles in body movement and protection. Muscles, particularly those attached to the skin, help regulate body temperature by generating heat during contraction, which is essential for maintaining homeostasis. Additionally, the skin provides a protective barrier for muscles and other underlying tissues, while also housing sensory receptors that can detect changes in the environment, influencing muscle activity. Together, they contribute to overall body function and interaction with the external environment.
