Sensory Development

Human Embryo stage 14 sensory placodes

Introduction

This laboratory 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.

The laboratory will also allow time for work on the group online project.

Also with the reorganization of the timetable, if we have time I will briefly review the integumentary system.

Objectives

Understand the early development of the eye, defining optic vesicles, optic stalks, optic fissure, optic cups, lens placodes and lens vesicles.
Understand the development of the retina, ciliary body, iris, lens, choroid, sclera and cornea.
Understand the development of external, middle and internal ear, including otic placode, otocyst, endolymphatic duct and semicircular canals.

Eye Development and Ear Development

Group Online Project

Second part of Laboratory, do not work on this in first half.
Each group project should now have individual peer assessment feedback added to the discussion page.

No assessment or signature on your comment - no marks! All individual assessments need to be signed in order to get your mark for this component.

I will explain how as a group to respond to the assessment comments, before final submission for co-ordinator assessment.
