How do the musculoskeletal and nervous systems work together to produce motion?
The afferent pathway conveys sensory information to the central nervous system (CNS) and the CNS response through efferent pathways to the skeletal muscles. The sensory information includes proprioception (the awareness of posture, movement, and changes in equilibrium and the knowledge of position, weight, and resistance of objects in relation to the body) and postural reflexes. Postural reflexes come from sensory organs in the inner ear, movement of the head and neck, optic sensations, nerve endings in muscles and tendons (proprioceptor or kinesthetic sense), antigravity or extensor muscle stretching, and plantar contraction of the extensor muscles of the lower leg (plantar reflexes).
