Document Summary
Chapter 21 musculoskeletal fitness (balance, flexibility, speed and agility) Balance is dependent upon signals received from the semi-circular canals in the inner year, kinesthetic (awareness of position and movement of parts) sensors in the muscles, joints, an tendons, and visual perception. The semicircular canals are located in the inner ear above the vestibule. The semicircular canals are three perpendicular loops that lie in three perpendicular planes. Semicircular canals are filled with fluids, the particles of which measure changes in movement and direction and disturb the hair that line the semicircular canals that provide information to the brain regarding the body"s movement. Proprioceptors are sensors that provide information about joint angle, muscle. Kinesthetic sensors within the muscles, tendons, and joints include the: length, and muscle tension: muscle spindles: Proprioceptors that are located in the skeletal muscles between the muscle fibers and load. The provide information to the cns regarding muscle length, tension,
