What is NOT a function of the skeletal system?

Support
Movement
Electric signal transmission
Protection

The correct answer is: Electric signal transmission

The skeletal system, composed of bones, cartilage, tendons, and ligaments, plays a crucial role in the overall structure and function of the human body. It provides support for the body, allowing us to stand, sit, and move. It also serves as a protective framework for vital organs, such as the brain, heart, and lungs. Additionally, the skeletal system is responsible for producing blood cells and storing essential minerals. Electric signal transmission is the only option that is not a function of the skeletal system. This task is primarily carried out by the nervous system, which is responsible for sending and receiving messages throughout the body. The skeletal system works closely with the nervous system to facilitate movement and maintain overall body function, but it does not directly participate in electric signal transmission. Therefore, option C is the correct answer as it is the only option that is not a function of the skeletal system.
