Introduction

Sensory placodes

This current page is a "landing page" for your study of sensory development (hearing and balance, sight, smell, taste) through the development of the specialized sense organs (ear, eye, nose and tongue). Note that other species have a range of additional sensory systems (magnetoreception).


Portions of the eye, nose and ear appear very early in development each as a specialized surface ectoderm region (placode) on the embryo. These regions must be connected to the central nervous system by neural pathways that originate as extensions from the developing brain.


This section of notes will not specifically cover the central nervous system component of these sensory systems, nor the sensory components of the skin (More? neural | integumentary | neural crest).


Use the specific sensory start page shown below to explore each system development.
