Question

Is the brain an integral part of the body's reflexes? explain

Answer 1

Reflexes come from the spinal cord.

Answer 2

No.

Reflexes are a different thing than normal movement, as the impulse does not travel to the brain. Instead, it travels directly to the spinal column and back to the effector muscle (the one that needs to move). For example, in the patellar reflex, something strikes your patellar tendon. The nerves there sense a shortening of the tendon, which sends the impulse along the nerves to your spinal column and then back to your leg muscles, telling them to kick your lower leg, relaxing the patellar tendon and getting rid of the danger.

However, the brain DOES play a part, as the brain contains interneurons, as well as the spinal cord. These interneurons, if activated, tell its destination to do nothing, or negate the effect of the reflex. For example, if you tried hard enough, you could stop your patellar tendon, or force your hand to stay on a hot surface for a longer period of time.

Answer 3

Things like flight response are however autonomic reflexes (whenever you strike your knee cap and it causes it to move) are controlled by the spinal cord - not the brain.
