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

Influence of Culture on Consumer Behavior LEARNING OBJECTIVES After studying this chapter students should be able to understand: 1. What culture is and how it impacts consumer behaviors. 2. How culture acts as an “invisible hand” that guides consumption-related attitudes‚ values and behavior. 3. How culture sets standards for what satisfies consumers’ needs. 4. How culture is learned and expressed in language‚ symbols‚ and rituals. 5. How consumers are always adapting to culture-related experiences

The Endocrine System Exercise 1: The Pituitary Gland obseRvations A. Please describe in detail the structures and features you observed on the pituitary gland slide. The Pituitary Gland Slides The Anterior Pituitary Gland was darker than the Posterior Pituitary Gland. In the Anterior Pituitary Gland Slide you can see Chromophobes and Acidophiles. Not super easy to distinguish which is which though. The Posterior Pituitary Gland slide showed Pitulcytes (Neuroglia) as light purple

1. Describe the general structure and function of the nervous system. The Nervous System is a "network" which delivers information and monitors the processes taking place in our bodies at all times. The nervous system in all its aspects allows us to function as a single controlled and coordinated unit. The basic nerve cell nerve cell is a neuron; a chain of neurons is actually a "communication cable "inside our bodies. Neuron structure is basically the cell nucleus‚ the dendrites which receive information

Essay – factors that influence pro-social behaviour What is pro-social behaviour? It is the voluntary actions that are intended to help or benefit another individual or group of individuals. This definition refers to the consequences of a person’s actions‚ motivations and their behaviour; behaviours which include a broad range of activities: sharing‚ comforting‚ rescuing‚ and helping. But there are a many different factors that influence this behaviour‚ that affect one’s decision to give‚ share

1. a. The action potential changes the membrane potential from -70 mV (resting) to +30 mV and back again to the resting membrane potential. b. This results from a change in membrane permeability first to Na then to K due to the opening of what type of ion channels? Voltage gated channels 2. a. Where is the density of voltage-gated Na+ channels the greatest? Axon hillock b. What areas of the neuron generate signals that open these voltage-gated channels? Dendrites and the cell body c. Opening
