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 why increasing

Honor Systems In the generation that we live in today‚ many students feel the need to cheat in order to do good in their academics. Applying honor codes or systems in schools should continue to be placed because they are extremely useful. They should be kept because a student’s future is at stake. They force discipline‚ prevent cheating‚ and create a sense of honesty‚ to not only themselves but to their surroundings. Honor systems would force discipline to those who do not follow the rules.

complex organism. It is composed of many different organs systems‚ which are vital for the body to function properly. They work with one another in order to carry out daily life activities and maintain the body’s proper functions. Among these organ systems lies one of the most important‚ the nervous system. The nervous system functions as the control center of the body‚ and it is in charge of the activities of the rest of the organs systems and the body’s components (Marieb‚ E.N. & Hoehn‚ K.). It

The adrenal glands are located on top of your kidneys‚ and they perform an important management function within your body. Adrenal glands secrete the hormone known as cortisol‚ which is used in the regulation of blood pressure‚ heart activity‚ metabolism and the immune system. These glands also produce aldosterone‚ which regulates electrolytes and bodily fluids. Whenever you exercise or feel stressed‚ your adrenal glands kick into gear‚ producing various levels of adrenaline. When things go wrong

The cardiovascular system plays a very important role in keeping the body alive. It is responsible for transportation of blood around the body. Blood carries many important things such as oxygen and nutrients to various organs allowing them to function properly. Blood also carries waste such as carbon dioxide to the lungs for gas exchange and metabolic waste to the kidneys for filtration and excretion. The cardiovascular system comprises of three different parts these being the heart‚ blood and

What is neural Darwinism? Defined as the large scale theory of the brain function by Gerald Edelman‚ the Neural Darwinism was first mentioned in the book called the Mindful Brain in 1978. He was awarded the Nobel Prize in 1972 for his improved understanding and capability to show methods by which the population of lymphocytes are actually capable of binding to foreign antigens which is further increased by the differential clonal multiplication that occurs in the brain. This meant that the human

It is amazing how some systems in our body works together in situations to help us to have the ability to react and be alert of our surroundings such as being in danger or suffering from stress which is an important factor of many health problems. The two systems that I am referring to are the endocrine and nervous systems. they help to regulate our bodies back to our normal state to help to maintain healthy functioning. There are two systems that work with one another to signal the brain when something

Terminal Buttons: are small bulges at the end of the axon and they send messages to other neurons. Synapse: It is the space between two neurons where the axon communicates with messages from other neurons (Dendrites) by using chemical messages. 3. Why is the function of our brain and our behavior so complex? List a minimum of least three reasons. The function of our brain and our behavior is so complex‚ because the brain is made up of different regions and parts‚ each one with a different function

It has many‚ many parts. The nervous system is divided into two main systems‚ the central nervous system (CNS) and the peripheral nervous system. The spinal cord and the brain make up the CNS. Its main job is to get the information from the

The inflammatory pathology of the nervous system Any of the etiologic agents of infection may give determinations to the nervous system. Usually these are secondary locations of other infections in the body: infectious diseases‚ endocarditis‚ pulmonary and urinary infections‚ regional inflammations etc. The pathways by which pathogens reach the bodies nervous system are: through blood pressure‚ arteries or veins‚ dissemination of nearby (eg the sinuses‚ internal ear‚ etc..) or through neuronal
