Histology
Contributed by: Haigh
  • 1. Histology, also known as microscopic anatomy or microanatomy, is the branch of biology that involves the study of the microscopic structure of tissues. It involves the examination and analysis of cells, tissues, and organs under a microscope to understand their structure, function, and relationships. Histology plays a crucial role in various fields of science and medicine, including pathology, physiology, and developmental biology. By studying histology, researchers and healthcare professionals can gain insights into the underlying mechanisms of health and disease, aid in diagnosis and treatment of illnesses, and advance our understanding of biological processes at the cellular level.
