Proprioceptors.
Proprioceptors are specialized sensory receptors that are responsible for providing information about the position, movement, and orientation of the body. They are located in muscles, tendons, and joints, and they work together to provide the brain with a sense of where the body is in space. Proprioceptors are essential for motor control and coordination, and they help to prevent injury by providing feedback to the brain about the position of the body during movement.
