AEB Practical 10 for Monday October 15 and Wednesday October 17.

This page provides histology support information for central nervous system structure.

Disclaimers

A Neuron - the functional unit of thenervous system

Obtain an understanding of the normal histological appearance of selected central and peripheral nervous system tissues namely spinal cord, cerebellum and peripheral nerve.
To examine unique microscopic characteristics of each of the nervous tissues.
To introduce the histology and neuropathology associated with cerebral infarction and haemorrhage.

Human embryo developing cortex, Week 8, Carnegie stage 22.
Inset (upper right) shows section overview and approximate level of section (red line).
Thin layer outer called cortical plate will eventually form the adult brain cortex.
- Other underlying layers are part of the development process and will continue to supply cells to the cortex through fetal period, these layers will eventually be almost completely lost.
Developing cerebrum layer thicknesses are shown in microns.

artifact - changes and distortions introduced to the normal tissue structure by the histological processing. Common artifacts include: folds (gives the tissue a darker appearance), tears (rips in the tissue can be seen in epithelia), shrinkage when tissues loose mainly liquid through histological processing, and cuts often used in tissue preparation.
