Final answer:
Visceral reflexes are controlled by autonomic neurons, spinal reflexes do not require input from the brain, spinal reflex movements are integrated mainly into the spinal cord, and cranial reflexes are integrated into the brain.
Step-by-step explanation:
Visceral reflexes are controlled by autonomic neurons, making the statement true. The autonomic nervous system controls involuntary bodily functions, such as heartbeat, digestion, and breathing.
These reflexes are not under conscious control and are regulated by the autonomic nervous system.
Spinal reflexes do not require input from the brain, which also makes the statement true. The spinal cord is capable of processing and generating reflex responses without involvement from higher brain centers. An example of a spinal reflex is the knee reflex.
Spinal reflex movements are integrated mainly into the spinal cord, making the statement true. The integration of sensory input and motor output for spinal reflexes occurs within the spinal cord. This allows for quick and automatic responses to stimuli without involving the brain.
Cranial reflexes, on the other hand, are integrated into the brain, which makes the statement true. Cranial reflexes involve sensory input and motor output that are processed within the brain. An example of a cranial reflex is the pupillary reflex.
