For the reflex arc, the processing of sensory information takes place in the:
|
|
Motor neuron
|
|
|
Brain
|
|
|
Medulla Oblongata
|
|
|
Spinal cord
|
Explanation:
Detailed explanation-1: -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-2: -Thalamus: The thalamus is the relay center of the brain. It receives afferent impulses from sensory receptors located throughout the body and processes the information for distribution to the appropriate cortical area. It is also responsible for regulating consciousness and sleep.
