Histopath Unit 1

The document provides an overview of general pathology concepts for medical technologist students. It defines key terms like histology, pathology, histopathology, and biopsy. It explains that pathology involves examining tissues and organs to study and diagnose disease. It outlines the goals for students to understand normal cell and tissue structure, pathological processes, and the ability to differentiate normal and abnormal tissues. The document also provides basic descriptions of cells, tissues, and defines the fields of histopathology and the procedures of biopsy and autopsy.

• The term Histology was coined in 1819 by


Karl Mayer, who combined the two Greek
words histos (tissues) and logos (study).

Pathology is a branch of medical science primarily concerning


the cause, origin and nature of disease. It involves the
examination of tissues, organs, bodily fluids and autopsies in
order to study and diagnose disease

Histopathology is the diagnosis and study of diseases of the tissues, and


involves examining tissues and/or cells under a microscope. Histopathologists
are responsible for making tissue diagnoses and helping clinicians manage a
patient's care.
