from the brain for initiation a response in the PNS (via motor neurons). Another role is the
spinal reflex.

QUESTION 22
The auditory sensory information would be detected by Karina’s sensory registers in her
peripheral nervous system and then transmitted to the brain via sensory neurons.
The auditory information would be received and processed in the primary auditory cortex in
the temporal lobe in the central nervous system.
The visual sensory information (watching the orchestra) would be detected in the retina by
photoreceptors and sent to the occipital lobe (primary visual cortex) for processing also.
Information would also be processed in the association areas and linked to other parts of the
brain to allow Karina to appreciate the full experience of the music.
QUESTION 23
The autonomic nervous system is self-regulating – consisting of the parasympathetic and
sympathetic branches responsible for the communication between the body’s visceral (nonskeletal) muscles and the internal organs and glands.
QUESTION 24
