Intro to Anatomy Flashcards
Anatomy
the study of form
Examining structure of the human body
Inspection
Palpation
Auscultation
Percussion
Cadaver dissection
Cutting and separating human body tissues to reveal tissue relationships
Comparative anatomy
Study of multiple species to learn about form, function, and evolution
Physiology
study of function
Subdisciplines:
Neurophysiology (physiology of nervous system)
Endocrinology (physiology of hormones)
Pathophysiology (mechanisms of disease)
Comparative physiology:
Study of different species to learn about body functions
Basis for much of our understanding of human physiology and the development of new drugs and medical procedures
Hippocrates
- Greek physician; “Father of medicine”
- Established a code of ethics (Hippocratic Oath)
- Urged physicians to seek natural causes of disease rather than attributing them to acts of the gods and demons
Aristotle
- Believed diseases had supernatural or physical causes
- Called supernatural causes of disease theologi
- Called natural causes for disease physiologi
- This gave rise to the terms physician and physiology
- Believed complex structures were built from simpler parts
Cladius Galen
- Physician to Roman gladiators
- Did animal dissections because use of cadavers was banned
- Saw science as a method of discovery
- Teachings were adopted as dogma in Europe in Middle Ages
Avicenna (Ibn Sina)
- “The Galen of Islam”
- Combined both Galen and Aristotle’s findings with original discoveries
- Wrote The Canon of Medicine, used in medical schools for 500 years
Illustrations from (a) Avicenna and (b) Vesalius
Avicenna - guessing what the human body looks like
Vesalius - drawing of our skeleton
Andreas Vesalius
- Catholic Church relaxed restrictions on dissection of cadavers
- Performed his own dissections rather than having the barber–surgeons dissect
- Published first atlas of anatomy, De Humani Corporis Fabrica (On the Structure of the Human Body) in 1543
Robert Hooke
- Made many improvements to compound microscope—two lenses: ocular lens (eyepiece) and objective lens (near specimen)
Invented specimen stage, illuminator, coarse and fine focus controls - His microscopes magnified only 30X
- First to see and name “cells”
- Published first comprehensive book of microscopy (Micrographia) in 1665
Antony van Leeuwenhoek
- Invented a simple (single-lens) microscope with great magnification to look at fabrics (200X)
- Published his observations of blood, lake water, sperm, bacteria from tooth scrapings, and many other things
Matthias Schleiden and Theodor Schwann
- Examined wide variety of specimens
- Concluded that “all organisms were composed of cells”
- First tenet of cell theory
- Considered to be perhaps the most important breakthrough in biomedical history
- All functions of the body are interpreted as effects of cellular activity
