In this lecture, Professor Diamond conducts a review of previous lectures including areas of the respiratory system, nervous system, vascular system, as well as hematology and cardiology. Her review takes the format of a quiz as she goes through slides and asks students to identify parts of the slides as well as answer multiple choice and true or false questions. Questions involve topics such as the hyelin cartilage, the trachea, lungs, ...more

Professor Diamond continues her discussion of the nervous system with a diagram of a cross section of a developing spinal cord in which she highlights the ependyma, the mantle layer, the neuronal soma, and the marginal layer. She compares the developing cord to an adult cord and discusses the ventricles, the posterior and anterior horn, and the lateral horn in the thoracic cord. After relating these to the sympathetic division of the autom...more

Professor Diamond continues her discussion of the nervous system and begins by revisiting her discussion of the ascending path. She notes the presence of substantia gelatinosa in the area of the second neuron and describes the concept of homunculus, which is the upside-down representation of the body in the brain, and notes that this does not occur in the face for reasons unknown to neurologists. Professor Diamond then begins describing th...more

In this lecture, Professor Diamond wraps up her discussion of the nervous system and moves on to the urinary system, beginning with the kidney. She concludes her discussion of the nervous system by describing the cochlea and diagramming its structure, and she indicates how cilia (hair cells) respond to and transmit information about vibrations in the fluid inside the cochlea. Professor Diamond then diagrams the constituents of the urinar...more

After a discussion of electrochemical cells, Professor Sylvia Ceyer defines the points of oxidation and reduction in a battery as the anode and cathode, respectively. She discusses the application of Faraday's Law and its relationship to electrochemical cells. Finally, the relationship between cell potential and Gibbs free energy is highlighted.

August 21, 2008 presentation by Stacey Bent for the Stanford University Office of Science Outreach's Summer Science Lecture Series. Meeting the world's growing energy needs in a sustainable fashion is one of the most pressing problems of our time. Professor Bent introduces the scope of the energy problem and some of the options for sustainable energy, then will focus on two main devices: solar cells and fuel cells. Solar cells convert t...more

If the extent of French collaboration during World War II has been obscured, so too has the nature of resistance. Although the communist Left represented the core of the resistance movement, resistors came from any different backgrounds, including in their ranks Catholics, Protestants, Jews and socialists. Unlike the relationship between de-Christianization and right-wing politics, in the case of the resistance there is no clear correlatio...more

In this lecture, Professor Diamond begins with a review of the respiratory bronchile. She then continues to discuss the structure of the lungs including the trachea, hilum, primary bronchi, pulmonary arteries and veins, nerves, alveoli and diaphragm, as well as the parietal pleura and the visceral pleura. After building this foundation she describes the process of innervation and the firing of the phrenic nerve before moving into an intr...more
