Therefore, Hippocrates established the basics of clinical medicine as it is practiced even today. ailynratilla021099 https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657864606 2021-07-22 03:24:45 UTC https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657864606 - He introduced numerous medical terms universally used by physicians, including symptoms, diagnosis, therapy, trauma and sepsis. ailynratilla021099 https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657865713 2021-07-22 03:25:47 UTC https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657865713 - He described the presentation of a great number of diseases without superstition. Their names are still used in modern medicine including diabetes, gastritis, enteritis, arthritis, cancer, eclampsia, coma, paralysis, mania, panic, hysteria, epilepsia and many others. ailynratilla021099 https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657866696 2021-07-22 03:26:40 UTC https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657866696 - Typhoid fever was well known to Hippocrates because he described the symptoms of that disease in great detail and named it ‘typhos’, possibly because of its typhoon-like impetuous character. ailynratilla021099 https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657868815 2021-07-22 03:28:30 UTC https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657868815 - Hippocrates and his theory followers wrote many works, which are now included in the Hippocratic Corpus, a collection of texts regarding medical and practice. Some of them contain anachronistic language styles and dissident philosophical views, indicating that they were clearly composed several centuries after the father of clinical medicine . ailynratilla021099 https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657872057 2021-07-22 03:31:16 UTC https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657872057 - The clinical and ethical basics of medical practice as well as most clinical terms used even today have their origins in the legendary physician from the island of Kos. ailynratilla021099 https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657874065 2021-07-22 03:33:03 UTC https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657874065 - He postulated the hypothesis known as pangenesis which explained that all body parts of a parent gave off invisible “seeds” to the semen resembling a miniature organism. This is transmitted during sexual intercourse to form a baby in the mother’s womb. ailynratilla021099 https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657890859 2021-07-22 03:47:20 UTC https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657890859 ARISTOTLE (384-322 BC) ailynratilla021099 https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657895689 2021-07-22 03:51:17 UTC https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657895689 - He emphasized the importance of blood in heredity. He thought that the blood supplied generative material for building all parts of the adult body, and he reasoned that blood was the basis for passing on this generative power to the next generation. ailynratilla021099 https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657899480 2021-07-22 03:54:38 UTC https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657899480 - In fact, he believed that the male’s semen was purified blood and that a woman’s menstrual blood was her equivalent of semen. ailynratilla021099 https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657900199 2021-07-22 03:55:17 UTC https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657900199 - These male and female contributions united in the womb to produce a baby. The blood contained some type of hereditary essences, but he believed that the baby would develop under the influence of these essences, rather than being built from the essences themselves. ailynratilla021099 https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657900322 2021-07-22 03:55:23 UTC https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657900322 - Aristotle’s ideas about the role of blood in procreation were probably the origin of the still prevalent notion that somehow the blood is involved in heredity ailynratilla021099 https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657901980 2021-07-22 03:56:56 UTC https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657901980 GREGOR JOHANN MENDEL ailynratilla021099 https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657906122 2021-07-22 04:00:34 UTC https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657906122 - Mendel’s idea was that distinct differences between individuals are determined by differences in single yet powerful hereditary factors. These single hereditary factors were identified as genes. Copies of genes are transmitted through sperm and egg and guide the development of the offspring. Genes are also responsible for reproducing the distinct features of both parents that are visible in their children. ailynratilla021099 https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657906522 2021-07-22 04:00:55 UTC https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657906522 - In his monastery garden, Mendel carried out a large number of cross-pollination experiments between variants of the garden pea, which he obtained as pure-breeding lines. ailynratilla021099 https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657907581 2021-07-22 04:01:52 UTC https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657907581 - Mendel’s success can be attributed in part to his classic experimental approach. He chose his experimental organism well and performed many controlled experiments to collect data. ailynratilla021099 https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657909307 2021-07-22 04:03:30 UTC https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657909307 - Mendel’s methodology established a prototype for genetics that is still used today for gene discovery and understanding the genetic properties of inheritance. ailynratilla021099 https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657910624 2021-07-22 04:04:44 UTC https://padlet.com/ailynratilla021099/472tmkjfmhrlxr0o/wish/1657910624
