ANATOMY

Detailed explanation-1: -Spinal Cord is the center that controls reflex action. Reflex actions are actions that are carried out quickly in response to a stimulus and thus do not involve any thinking, and thus are under the control of spinal cord.

Detailed explanation-2: -A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.

Detailed explanation-3: -The correct option is A True. Reflex action: Reflex action is an immediate and involuntary action taken against a certain stimulus. It is under the control of the spinal cord and is not controlled by the brain.

Detailed explanation-4: -Motor Functions-directs your body’s voluntary muscle movements. Sensory Functions – monitors sensation of touch, pressure, temperature and pain. Autonomic Functions – regulates digestion, urination, body temperature, heart rate, and dilation/contraction of blood vessels (blood pressure).
