==Introduction==
Course convenor: Dr. Elizabeth Tancred

The aim of this course is to provide students in the BSc and BMedSc programs with a basic understanding of the structural organisation of the human central nervous system in sufficient depth to form the basis for further clinical or research studies of the nervous system.

The following images are prepared for Dr Tancred's Neurodevelopment class from UNSW Embryology. The listed cross-sections are recommended to be viewed in the order in which they are shown below.

'''Begin''' with a simplified introduction by looking through [[K12 Brain Awareness Week|Brain Awareness Week]]. Then return to this page for the remainder of the class.

* '''Heart bulge''' can be seen on lower ventral surface.

Note the still open cranial (top) and caudal (bottom) neuropores. These are the last parts of the tube to close.

! Stage 11 - Cut through the neural tube
|-
| [[File:Stage11_sem11.jpg|300px]]
| This slightly older embryo has been broken in half close slightly away from the midline to show features of the neural tube.
* At the level of the hindbrain and spinal cord - (right of image) the floor, wall and roof of the neural tube can be seen. Notice also the rhombomere bulges at the level of the hindbrain.
* In the head region - (top of image) part of the lateral wall of the neural tube remains, at the level of midbrain. A segment of the forebrain has been removed to show the internal surface of this region.

! Stage 10 - Neural Groove
|-
| [[File:Stage10_sem2.jpg|300px]]
| This is a dorsolateral view of the embryo. The amniotic sac has been removed to show the still open neural groove.

* '''Neural groove''' forming from neural plate on upper surface.
** large brain fold region to left of image.
** narrow spinal cord region to right of image.
* '''Heart bulge''' can be seen on lower ventral surface.
* '''Connecting stalk''' to the right of image.
* '''Amniotic membrane''' cut edge shown at edge of developing embryo.

|-
| [[File:Stage10_sem6.jpg|300px]]
| This is a dorsal view of the same embryo with the future head, and brain, now shown at the top of image.
|-
| [[File:Stage10_sem10.jpg|300px]]
| This is a lateral view of a later embryo showing the neural groove closing to form the neural tube.

Note the still open cranial (top) and caudal (bottom) neuropores. These are the last parts of the tube to close.

! Stage 11 - Cut through the neural tube
|-
| [[File:Stage11_sem11.jpg|300px]]
| This slightly older embryo has been broken in half close slightly away from the midline to show features of the neural tube.
* At the level of the hindbrain and spinal cord - (right of image) the floor, wall and roof of the neural tube can be seen. Notice also the rhombomere bulges at the level of the hindbrain.
* In the head region - (top of image) part of the lateral wall of the neural tube remains, at the level of midbrain. A segment of the forebrain has been removed to show the internal surface of this region.
