Introduction
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 a Neurodevelopment class from UNSW Embryology. The listed cross-sections are recommended to be viewed in the order in which they are shown below. A direct link ANAT3411 to this current page appears on the lefthand menu of every embryology page.
- Begin with a simplified introduction by looking through Brain Awareness Week.
- Then return to this page for the remainder of the class.
