The sense of smell is much less essential than vision, audition or the somatic senses, and will
therefore receive less emphasis in this course. However, since olfactory dy

Cranial nerves are components of the peripheral nervous system that originate in the
brain and upper cervical spinal cord. They are called cranial nerves because they exit the
CNS through the cranium

1. What are postsynaptic potentials?
Postsynaptic potentials are created when a NT binds to a ionotropic (direct) or metabotropic
(indirect) receptor. PSP are when there is a change in the neurons membr
