- "3 stages of disease" in history
-
1. imbalance
2. fever
3. excretion or death - Hippocrates
- "father of western medicine." thought diseases had natural causes/imbalance. observed symptoms.
- Aristotle
- compare human organs to animal ones, observed difference between nerves and tendons, believed in embryos
- Herophilus
- "Father of Anatomy." studied brains as the center of the nervous system. distiguished between cerebrum and cerebellum and between sensory and motor nerves.
- Erasistratus
- leader of alexandrian school, studied heart, delineated veins and arteries, thought that veins brought blood and arteries brought "animal spirits"(seems like hormones) and nerves brought nervous spirits to the organs, and discovered parts of the brain
- Galen
- doctor to the gladiators, said arteries carry blood instead of air, studied muscles, bones, and heart. used animals to study. He was physician to the Emperor's son and saw a connection between spinal cord, paralysis, and movement. saw diaphragm used in breathing. studied liver, kidneys, and heart but was wrong on their locations.
- Andreas Vesalius
- dissected people and drew findings. undid a lot of Galen's inaccurances, but was confused on others. Helped find circulation. Criticized bloodletting.
- Michael Servetus
- discovered blood went from the right chamber to the lungs and that the septum was impermeable
- Realdo Comlubus
- 1st used the term circulation for blood and studied breathing
- William Harvey
- acknowledged and creditted Columbus and studied the heart
- "tomy"
- to cut
- "ana"
- apart
- gross anatomy
- unaided eye study of large organs
- microscopic anatomy
- study of cells(cytology) and tissue(histology)
- radiological anatomy
- electromagnetic imagin, can detect irregular blood flow
- anatomical position
- face forawrd, standing erect, hands at sides w/ palms forward
- sagittal
- cut dividing left and right, a midsagittal divides body in half from top to bottom
- transverse
- cuts horitantal to divid top and bottom, one slice=cross section
- frontal
- cuts front from back, also called a coronal section
- They what?
- they dissected living breathing people!!!!!!!!!!!
- bilateral symmetry
- right is almost perfect reflection of left
- superior
- to the top
- posterior
- to the back
- inferior
- below
- medial
- towards the mid sagittal
- anterior
- forward
- lateral
- to the sides
- proximal
- closest to point of attatchment for the limb
- distal
- further away from point of attachement

- holds brain
- spinal cavity
- holds spinal cord
- thoracic cavity
- holds heart, esophagus, longs, trachea, branchi
- abdominal cavity

- organelle
- performs specific function within a cel
- homeostasis
- equilibrium, balance, health
- metabolism
- sum of energy reactions at a given time
- tissues
- group of similiar cells that perform specific functions
