Histology Lecture 1: Background and History Flashcards
Definition: the study of the microscopic anatomy of cells and tissues of plants and animals.
Histology
Definition: the study of changes in tissues caused by disease
Histopathology
What type of epithelium tissue is associated with the urinary system?
Transitional/Urothelium
The 1906 Nobel Prize in Physiology or Medicine was awarded jointly to two histologists “in recognition of their work on the structure of the nervous system.” Name them.
Camillo Golgi and Santiago Ramón y Cajal
Correctly interpreted the neural structure of the brain
Ramon y Cajal
Invented the staining technique used to visualize neural structure of the brain
Golgi
Showed in 1761 that diseases are not due to humoral imbalances but to lesions in organs (i.e. described disease at the anatomical level) [Last name only]
Morgagni
Main contribution was the perception that the diverse body organs contain particular tissues, or “membranes.” He described 21 such membranes. [Last name only]
Bichat
Introduced notion of tissues as distinct entities and maintained that diseases attacked tissues rather than whole organs or the entire body. [last name only]
Bichat
One of two parts of life put forth by Bichat. Argued that this life was the life of the heart, intestines, and other organs, and was regulated by a collection of small, independent, thoracic brains (ganglionic nervous system).
Organic
One of two parts of life put forth by Bichat. Argued that this life was composed of symmetrical organs such as the eyes, ears, and limbs. This life included habit and memory and was ruled by wit and intellect.
Animal
Pioneered concept of pathological processes through the application of the cell theory (omnis cellulae e cellulae). Took histopathology to the cellular level.
Virchow
Realized early on that the part of the cell theory that required all cells to be derived from existing cells (omnis cellulae e cellulae) could give insight into pathological processes.
