Chapter 7 - Sensory Systems
The sensory pathways arise with receptors and follow various peripheral nerves (as described in Chapter 3). The sensations include: somatic sensation (including trigeminal sensation from the head); special visceral sensation (taste and olfaction); hearing; vestibular function; and vision. There are pathways that convey this information through the central nervous system. Some of these pathways terminate in the cerebral cortex, providing the basis for conscious sensation. Other sensations are largely unconscious, including much proprioceptive function. Sensory pathways often participate in control of movement or in reflex responses. These respnses will be discussed with the sensory modality (although many of the somatic reflexes have been discussed in chapter 5, the spinal cord.
