Lauren Clayton BIOL–15 Extra Credit Bugs‚ Guts‚ and Brains Seminar Summary During the seminar “Bugs‚ guts and brains: How gut microbiota shapes your mind and body” on November 7‚ Physiologist from UC Davis‚ Dr. Helen Raybould discussed how gut microbes in humans and animals affects neurophysiology based primarily on the foods we eat and the genes expressed in the gut. There is an intersection between micro and host physiology that affects the overall health and behavior of the host. To understand

Writing III – Acid-Base Balance Congestive heart failure (CHF) is caused by the inability of the heart to fill correctly‚ eject blood completely‚ or a combination of the two‚ which results in a decrease in cardiac output. Chronic hypertension (CH) is a constantly elevated blood pressure. Peripheral vascular disease (PVD) causes a restriction in blood circulation due to atherosclerosis‚ fatty deposits on the inner linings of the arteries that cause a blockage of blood flow; arteriosclerosis‚ loss

CHAPTER I INTRODUCTION 1.1 Background Food is one of human sources of calorie‚ protein‚ fats‚ and nutrition. Yet‚ because of the highly nutritious content‚ food is susceptible to growth of microorganisms. By the presence of microorganisms in food‚ the food is more likely to have shorter shelf life. Thus‚ mostly it is resolved by the addition of antimicrobial substances to food‚ such as condiments and preservatives. Condiments and preservatives could inhibit the growth of microorganisms

parenchymal arterioles have unique properties compared to the microvasculature found in other organs; endothelial cells are wrapped around by specialized contractile cells‚ termed pericytes or Rouget cells [60]‚ that are embedded in the basement membrane‚ separating it from the endothelial cells‚ and project a sheath around endothelial cells‚ where they communicate with the endothelium through either

Lead is a metal that occurs naturally in the earth’s crust‚ but human activity‚ such as mining‚ burning fossil fuels and manufacturing‚ has caused it to become more widespread. This element‚ however‚ has no known purpose that can be beneficial for humanity. Rather‚ it is an extremely harmful chemical that can cause serious damage and even potentially death when at high concentrations. Events‚ like the one in Flint‚ Michigan‚ where shortcuts by the government caused serious lead poisoning in the town

at the neuromuscular junction. . The acetylcholine binds to the receptor sites on the motor end plate membrane. The neurotransmitter‚ acetylcholine‚ increases the motor end plate’s permeability to sodium and potassium ions‚ which produces an end-plate potential. This potential depolarizes the sarcolemma that creates a muscle action potential that is propagated throughout the muscle membrane causing depolarization of the transverse

A change in membrane permeability is caused when the visual pigments (photopsin) in the cones change conformation when they absorb the light. The Na (sodium) channels would close‚ which results in hyperpolarization due to ongoing K (potassium) current‚ which results in the
