WebThe cerebellum is responsible for high-speed accurate regulation of limb position including balance posture and motor coordination; compares accomplished movement to planned movement. It receives information from both the spinal cord and the cerebral cortex and sends information to the spinal cord via brainstem nuclei. WebMar 17, 2024 · Collectively, the postural reflexes provide the basis for automatic control of posture, balance, and coordination in a gravity-based environment. Control of posture and movement is organized at three different hierarchical levels: the highest of these comprises the association cortex with major inputs from the limbic cortex. skh management services

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.

Web1. What is the difference between a reflex action and walking? Solution: Reflex actions are the involuntary actions that occur in response to stimuli. They occur without involvement of conscious areas of brain. All the reflex actions are unconscious actions. Reflex action involves the brain and spinal cord of central nervous systems.
