Individual Assessment

  • Place your work on this page under a sub-sub-heading of your ROI.
  • Add your own sub-sub-heading below any existing student ROI.
About this Assessment
A demonstration of this assessment will be given in the practical class. Below in the collapsible table are examples of links from a virtual slide. There is also a permalink help page.


Virtual Slide Features - Stage 22 Liver
Stage 22 image 034.jpg Virtual Slide - Stage 22 Liver and Ductus Venosus      All Virtual Slides

The links shown in the table below are to specific features shown on the Human embryo (stage 22) Liver and Ductus Venosus virtual slide. See also notes on Liver Development

Clicking the text will open the slide at a detailed view with the structure generally located in the centre of the view. The slide then can also be zoomed out from the set magnification using the controls in the upper left or the mouse.

Use your browser back button to return to this table.

You can also make your own selected feature view.
  1. Set the virtual slide to the region and zoom of interest.
  2. Click the Permalink (lower righthand corner).
  3. Then bookmark in your browser, or copy the web address.

Using the Human Embryo Carnegie Stage 22 virtual slides shown below:

  1. Using the "mobile view" Identify a sensory region of interest (ROI) in one of the virtual slides below.
  2. View at a high magnification (detailed view) the region of interest.
  3. Generate a permalink to the ROI.
  4. Paste the link on your own page and write a brief description of what the linked region is showing.
  5. Add a link to the embryology page and sub-heading that relates to your identified feature.
  6. Paste all the content (text and links) you have just generated on this page under a sub-heading named after your ROI.

Student ROIs

This is a sub-sub-heading

Cochlear Duct

link to permalink image:| Cochlear Duct


The cochlear duct is an fluid filled cavity inside the cochlea. It located between the tympanic duct and the vestibular duct, and between the basilr membrane and reissner's memebrane. It derived from otic placode, otic vesicle, and originated from surface ectoderm.

Semicircular Canal

link to permalink image:| Semicircular Canal

The semicircular canals are part of the inner ear.They are lined with cilia and filled with endolymph which is a liquid substance. Every time the head moves, the endolymph moves the cilia and this movements of the cilia are communicated to the brain. As a result, the brain knows how to keep the body balanced, regardless of the posture.

Lens of the Eye

Link to permalink image: Anterior portion of the Lens of the embryonic eye

The lens of the eye is derived from surface ectoderm. Said ectoderm forms a lens/optic placode in the head region which then invaginates to form a lens pit and then later a lens vessel. Lens fibres then develop and are surrounded by a lens capsule. The main function of the lens is to focus light onto the retina.

Embryology link Vision - Lens Development --Development Overview

Retina of the Eye

Link to permalink image: Retina of the Eye

The retina is the light sensitive portion of the eye. It contains 10 separate layers, including the photoreceptor layer which is comprised of rods and cones. These rods and cones convert light into signals, which are then communicated to the brain via the optic nerve. The image above displays a Carnegie Stage 22 retina. The nerve fibre layer is particularly prominent in this image and is the pale layer closest to the vitreous chamber. The processes of rods, cones and ganglion cells can be observed migrating towards the optic nerve.

Retinal Pigment Epithelium

Link to permalink image: Retinal Pigment Epithelium

The Retinal Pigment Epithelium (RPE) is a complex differentiation of the retina, is generated from the optic neuroepithelium, and is structurally made up of cuboidal cells and multiple villi on its apical side. Its lateral sides are joined together by gap junctions and adherens and the RPE's basal side is in contact with Bruch's membrane. It lies between the neuronal retina and the choroid. The section shows that in the embryo the pigmented retina is still separated by a space from the neuronal retina. This space will be decreased in the adult and closely appose the two to each other.
