Introduction
This section of notes is a introduction to development of senses (sight, smell, hearing and balance) through the
development of the specialized sense organs (eye, nose and ear). Portions of the eye, nose and ear
appear very early in development as specialized surface regions (placodes) on the embryo,
these regions must be connected to the central nervous system by neural pathways that originate as extensions of the central nervous system.
There are also specific notes on Hearing and Balance, Vision, Smell and Taste development.

Comments
These notes introduce the development of the senses. Our senses are a combination of several different embryonic tissues, which for us to
"sense" must also connect with the central nervous system.
