What is Histology?
Histology is the study of the microscopic structure of tissues. It involves examining the anatomy of cells, their organization into tissues, and how these tissues function within the body. Research in histology provides crucial insights into the normal and pathological states of tissues, aiding in the understanding of disease mechanisms and the development of medical treatments.
