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 now more specific notes on each sensory system Hearing and Balance, Vision_Development, Smell and Taste development. |
