Which body system covers, shapes, and supports the skeletal tissue?

The muscular system is directly responsible for covering, shaping, and supporting the skeletal tissue. Skeletal muscles attach to bones and, when they contract, they create movement and help maintain posture. This system works closely with the skeletal system; muscles pull on bones to allow the body to move and engage with its environment effectively.

In contrast, while the nervous system regulates muscle movement by transmitting signals to and from the brain, it does not directly shape or support skeletal tissue. Similarly, the endocrine system plays a role in hormone regulation, influencing various body functions, but it does not directly interact with skeletal tissue in a manner that supports or shapes it. Lastly, the cardiovascular system is focused on the circulation of blood and does not contribute to the physical support or shaping of skeletal structures. Therefore, the muscular system is the correct answer, as it actively engages with skeletal tissue to fulfill these functions.
