  1. Physiology in the 17th and 18th Centuries

  2. Robert Brown; Discovered the nucleus in 1833 http://ajweinmann.files.wordpress.com/2010/02/nucleus.jpg http://www.brianjford.com/porchida.jpg http://www.xtimeline.com/__UserPic_Large/108208/evt111002215900491.jpg Traveled to Australia to carry out a natural research. He studied 1700 plant species. Took over the Banksian Botanical Collection in the British Museum While observing collected plant cells, he discovered an opaque spot in the middle of the cell, and named it the nucleus Findings were published in the Linnean Society paper in 1833 He discovered that its structure was directly related to the cellular tissue

  3. John Hunter:1728-1793, The founder of Modern Surgery Observations on certain parts of the animal oeconomyhttp://special.lib.gla.ac.uk/exhibns/scottish/sci-med.html http://www.healio.com/endocrinology/ news/print/endocrine-today/%7B42e6988 5-5267-4cf0-8a9d-2184664d3b20%7D/ john-hunter-founder-of-scientific-surgery Furthered relationship between physiological and anatomical studies Proposed that animal functions, along with organs, allowed life Developed the anatomical series: simple to “perfect” Organization of Organs: “The more complicated a machine is, the more nice its operations are...therefore there is a more intimate connection through the whole.”

  4. Antony van Leewenhoek: an unlikely scientist https://dspace.lib.uoguelph.ca/xmlui/handle/10214/6386 http://creationrevolution.com/2013/01/red-blood-cells-are-frisbees-tanks-and-wheels/ http://www.ucmp.berkeley.edu/history/leeuwenhoek.html Discoveries Bacteria Free-living and parasitic microscopic protists Sperm cells Blood cells Nematodes and Rotifers Observed green charophyte alga in lake water Made descriptions of protists including Vorticella Also made many different types of microscopes 1698 demonstrated circulation in the capillaries of an eel

  5. Marcello Malpighi Discoveries • Capillaries • Renal Glomeruli • Urinary Tubules • Dermal Papillae • Taste Buds • Glandular components of the liver http://www.vhlab.umn.edu/atlas/physiology-tutorial/graphics/fig2.gif http://www.interactive-biology.com/wp-content/uploads/2012/07/RedBloodCells3.jpg http://upload.wikimedia.org/wikipedia/commons/4/48/MarcelloMalphigiMiall.jpg Facts Used the microscope to express the major types of plant and animal structures Identified and described the pulmonary and capillary network connecting small arteries with small veins First to see the red blood cells and attribute the color of blood to them in 1666 Concluded that most living material are glandular in organization Saw an analogy between plant and animal organization

  6. Robert Hooke Discoveries/Inventions Created “Hookes Law” Invented Universal Joints Anchor Escapement Balance Spring Coined the term “Cell” Wrote the book Micrographia Disproved Aristotle’s theory of fossiles Assisted Leeuwenhoek with the discovery of “little animals”
