Document Summary
Below threshold of dependence = need others to do things for you. Start lower on the downward slope if you don"t pay attention to muscular fitness problems in 60s vs 90s. Signals upon which balance is dependent: semi-circular canals of inner ear. Semicircular canals (3- lined up as perpendicular loops): angular acceleration. Lined with tiny heads and fluid with particles floating around in them. Fluid keeps moving even when you stop and stand still: kinesthetic sensors in muscles, tendons, joints. Embedded in the tendons, close to the muscle insertion. Detect tension in the tendon of a contracting muscle try to relax the tendon to prevent tearing (reflex= quick signal to spinal cord and back not brain) Provide info on muscle length, tension, load. Highest density in small muscles designed for fine motor control. Located in the connective tissue of a joint capsule. Signal the extremes of a joint range.
