In this image of an area of white matter of the brain several fibrous astrocytes can be evidenced by Immunohistochemistry against GFAP, a protein of the cytoskeleton specific of this cell type in the central nervous system. Fibrous astrocytes differ from protoplasmic astrocytes in that they present extensions that are oriented in the same ...

The histological technique is complex and with many steps, a little mistake in one step, a small particle, invisible to the naked eye, we strained during the Assembly, etc... they can cause unwanted effects, the appearance of foreign bodies in the preparation during the observation under a microscope.
These phenomena are called "artifacts" and ...

The typical colour corresponds to the pattern of black background on which stand out spots/bands (depending on the subspecies) of an ...

This interactive diagram shows the elements of a scanning electron microscopy as well as how it works

This interactive diagram explains how a biological structure can display different images under the microscope depending on the orientation and depth of section.

This interactive diagram shows as the same structure (for example a renal corpuscle) is seen in the types of microscopes used in Histology.
- The light microscope (LM) can show tissues magnified up to 1,000 times. As it uses visible light, tissue can be stained with different techniques which can show different structures stained in different ...

This interactive diagram shows how to operate a light microscope; the magnification change, focus and contrast selection and its results.

This interactive diagram shows different types of microtomes, how they work and for what they are commonly used in histology.

This interactive diagram shows the elements of an optical microscope, as well as their functions.
