Get an overview of basic microbiology and the concepts involved, including the bacterial growth curve and classifying organisms based on morphologies. This lecture describes blood, urine and skin/soft tissue cultures, focusing on the types of media, sample collection processes, culture procedures, as well as speciation and susceptibility testing.

This is a re-posting of the notes I originally posted on reddit from a general cell biology class I took in spring 2011. I re-scanned them after signing all of them at the suggestion of another redditor. Here they are again in all of their glory. Actin Filament Apoptosis Cell Cycle and Cyclin Endocytic Pathway…

The oldest descriptions of cancer were written in Egypt as early as 3000 B.C., as part of an ancient Egyptian textbook on surgery. The name, "cancer" comes from the Greek word carcinos, which means crab. Hippocrates used this term to describe the disease because of the projections of a cancer invading nearby tissues. During the 16th century, when the theory of bodily humors prevailed, it was believed that an excess of black bile caused cancer. The renowned anatomist Andreas Vesalius searched diligently for this black bile and ultimately discarded the this theory when he was unable to find it. In 1838 a botanist named Matthias Schleiden and Theodor Schwann, a physiologist, proposed that all living things were composed of fundamental units called cells. Shortly after the introduction of this idea, Virchow (the "father" of pathology) proposed that cells only arose from other cells and that growth could only occur as a result of hypertrophy or hyperplasia. Virchow studied cancers under with a microscope and recognized that they represented hyperplasia in an extreme form that he dubbed "neoplasia."

The innate immune system, which consists of the normal flora, physical barriers such as the skin, antibacterial proteins and phagocytic cells, is an important defence mechanism against infection. Many responses to ‘harm’ are detected by pattern recognition molecules such as […]

In Part 1 of Professor Fink's 2-Part Series on the Spinal Cord, he reviews the anatomy of the Spinal Cord and the functional organization at each segmental level. Professor Fink describes the horizontal flow of sensory information into the Spinal Cord and the flow of motor commands out of the Spinal Cord. Reference is made to Gray Matter, White Matter, Spinal Nerves, Dorsal Root Ganglion, Ventral Root, Commissures, decussation, Somatic Reflexes, Dorsal (Posterior) Gray Horn, Ventral (Anterior) Gray Horn, Lateral Gray Horn. Check-out professor fink's web-site or additional resources in Biology, Anatomy, Physiology & Pharmacology: www.professorfink.com Lecture Outlines by Professor Fink can be purchased from the WLAC Bookstore at: http://onlinestore.wlac.edu/fink.asp
