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 this‚ the neural pathways by which macronutrients

REVIEW SHEET EXERCISE 6 Cardiovascular Physiology NAME: LAB TIME/DATE: 1. Define each of the following terms: • autorhymicity- The heart is autorhythmic. This means it generates its own rhythmic action potential independent of the nervous system. • sinoatrial node- is the impulse-generating (pacemaker) tissue located in the right atrium of the heart‚ and thus the generator of normal sinus rhythm. • pacemaker cells- are specialized cells that cause involuntary muscles and tissues to

Session 9: The Nervous System - Assignment #2 PhysioEx Assignment : Exercise 3 Neurophysiology of Nerve Impulses Activity 1: The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Increasing the extracellular K+ causes the membrane potential to change to a less negative value because when K+ ions diffuse out across the membrane they are leaving behind a net negative charge. 2. Explain
