Final answer:
The nervous system is responsible for proprioception, which involves sensory input from various receptors in the body that inform about the position and movement of body parts.
Step-by-step explanation:
The system of the body that plays a role in proprioception (perception of an object's position) is the nervous system. Proprioception is a general sensory perception that provides information about the location and movement of body parts. This involves sensory input from receptors that respond to stretch and tension in muscles, joints, skin, and tendons, which is processed by the nervous system, including the brain and spinal column. The vestibular system also interacts with proprioceptive information to help maintain balance and control movement.
