NATIONAL CENTER FOR CASE STUDY TEACHING IN SC CE Wearing on Her Nerves: Exploring the Interrelation between the Nervous and Muscular Systems by Kathleen G. Brown‚ Nursing Department Sharon S. Ellerton‚ Biological Sciences and Geology Queensborough Community College‚ City University of New York Part I – Rise and Shine? Kathy‚ a 20-year-old woman‚ awakens one morning to a tingling‚ numb sensation covering both of her feet. This has happened to her a number of times throughout the year

Human Sensory Systems Objectives · Describe how sensory receptors communicate to the central nervous system. · Describe receptors that detect temperature‚ pain‚ touch and pressure‚ muscle length and tension‚ and blood pressure. · Describe the nature of vision in terms of its stimulus on the function of rod and cone cells. Introduction The function of the brain is to convey messages to different parts of the body. Messages are conveyed from a nerve cell to another nerve cell‚ muscle cell

Investigating the physiological response of anxiety through general knowledge and math questionnaires‚ with a focus of inducing anxiety through music. The aim of this study was to investigate the physiological effects associated with math anxiety‚ with a further aim to explore this in relation to tense music exposure. It was hypothesised that a maths questionnaire would produce a significantly higher anxiety response than a general knowledge questionnaire. It was also hypothesised that exposure

Hypotension In physiology and medicine‚ hypotension is abnormally low blood pressure‚ especially in the arteries of the systemic circulation. It is best understood as a physiological state‚ rather than a disease. It is often associated with shock‚ though not necessarily indicative of it. Hypotension is the opposite of hypertension‚ which is high blood pressure. Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood. If it is lower than normal

Eliciting (Generating) a Nerve Impulse 1. Why don’t the terms depolarization and action potential mean the same thing? Depolarization has to do with surfaces becoming more negative or positive and reaches a certain point called a threshold. When the threshold is reached‚ an action potential is initiated. 2. What was the threshold voltage in Activity 1? The threshold voltage in Activity 1 was 3.0. 3. What was the effect of increasing the voltage? How does this change correlate to changes

1/03/13 Introduction to Pharmacology II Targets of Drug Action March 5 How do drugs work? | Nearly all drugs act by interfering or inhibiting natural processes which are required for normal physiological function but which may have been disrupted by disease. | Paul Ehrlich 1845-1915 | Observed that certain chemicals or drugs bound in a selective manner to some but not all cells. He recognised that the cells must have chemical recognition sites for these drugs. The concept of a “receptor”

You should include diagrammatic representations to help with understanding the details. Sensory system is systems that comprise of nerves and cells that convey data to the cerebrum and from the mind to different parts of the body. Cells that make up the sensory system are called neurons. The sensory system is the thing that controls our correspondence its activity

LEVELS OF ORGANIZATION OF NERVOURS SYSTEM: NEURONS: * STRUCTURE AND FUNCTION: Specialized cell transmitting nerve impulses; a nerve cell. Neurons have specialized projections called dendrites and axons. Dendrites bring information to the cell body and axons take information away from the cell body. Neurons communicate with each other through an electrochemical process. Information is transmitted to the receiving cell at junctions via chemical messengers called neurotransmitters. At this juncture
