Histology

The study of microscopic anatomy, focusing on tissues and their structures.

Tissue staining

A technique that uses dyes to highlight specific structures within tissues, making them visible under a microscope.

Reticular theory

The idea that nerve cells form a continuous network, interconnected like a mesh.

Neuron doctrine

The idea that the nervous system is made up of individual, separate nerve cells that communicate with each other.
