Cell Types in Nervous Tissue: Histology Of Nervous Tissue Review Sheet
Nervous tissue is composed of a variety of specialized cells that work together to receive, process, and transmit information. The two main cell types in nervous tissue are neurons and glial cells.
Neuronsare the primary functional units of the nervous system. They receive, process, and transmit electrical and chemical signals. Neurons have a cell body, dendrites, and an axon.
Glial cellsprovide support and protection for neurons. They make up about 90% of the cells in the nervous system. There are several types of glial cells, including astrocytes, oligodendrocytes, and microglia.

User Queries
What are the key cell types found in nervous tissue?
Nervous tissue comprises neurons, the primary information-processing units, and glial cells, which provide support and protection.
How does the structural organization of nervous tissue contribute to its function?
The organization of nervous tissue into gray matter (neuron-rich) and white matter (myelin-rich) facilitates efficient communication and information processing.
What role does histology play in the diagnosis of nervous system disorders?
Histological analysis of nervous tissue biopsies aids in the diagnosis of neurological diseases by revealing cellular abnormalities and structural changes.
