WebDec 5, 2015 · Several reflexes which operate at a spinal or brainstem level have been thought to be implicated in posture and locomotion. These are: (i) The stretch reflex. Stretching of a muscle stimulates the spindle stretch receptors and causes contraction of the muscle by a simple reflex usually involving only two neurones directly. (ii) The tendon jerk. WebPosture is the position and carriage of the limbs and the body as a whole. Except when lying down, the first postural requirement is to counteract the pull of gravity, which pulls the body toward the ground. This force induces stretch reflexes to keep the lower limbs extended and the back upright.
WebTaken together, these posture-stabilizing mechanisms resist deflections from the posture at which balance of muscle and external forces is maintained. Empirical findings suggest that for each muscle, these mechanisms become functional at a specific, spatial threshold-the muscle length or respective joint angle at which motor units begin to be ...
