contains the cell nucleus and much of the chemical machinery common to most cells. * Dendrites are the parts of a neuron that are specialized to receive information. * The axon is a long‚ thin fiber that transmits signals away from the soma to other neurons or to muscles or glands. * The axon ends in a cluster of terminal buttons‚ which are small knobs that secrete chemicals called neurotransmitters. * The Neural Impulse: Using Energy to Send Information * The Neuron

PHYSIOEX 9‚ ACTIVITY #3 Review Questions ACTIVITY #1 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? 3. Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? 4. Discuss the relative permeability

Christina Piccininni Professor Cody English 122 February 28 2013 Amyotrophic Lateral Sclerosis: The Breakthrough Amyotrophic lateral sclerosis (ALS)‚ otherwise known as Lou Gehrig’s‚ slowly terminates motor neutrons in the brain and spinal cord. Motor neurons are an important part of the body’s neuromuscular system; the neuromuscular system is what aids our body’s movement. It is made up of the brain‚ muscles‚ and nerves. Upper motor neurons send messages from the brain to the spinal cord‚ while

Week 2 Reading Summary : Chap 1-3 Chapter 1 Anatomy: studies the structure of body parts and their relationship to one another. Can be seen‚ felt‚ examined. Physiology: concerns the function of the body in other words‚ how the body parts work and carry out their life-sustaining activities Complementary of structure and function Function reflect structure‚ what a structure can do depends on is specific form Levels of structural organization: Cells – smallest living unit

Sannu’s Story A. In Sannu’s case why is there both sensory loss and muscle weakness? Leprosy is a disease that has been known since biblical times. It causes skin sores‚ nerve damage‚ and muscle weakness that gets worse over time. Leprosy is caused by the bacterium Mycobacterium leprae. It is not very contagious and it has a long incubation period (time before symptoms appear)‚ which makes it hard to know where or when someone caught the disease. Children are more likely than adults to get the

Chapter 3 of Introduction to Psychology is titled "Neuroscience and Behavior" and contains three different modules. Module seven contains information on Neurons and how they function. Module eight contains information about the nervous system and the endocrine system‚ and it also explains how the body communicates from within. Module nine is the last module and contains information on the brain. The different parts and functions of the brain are also found in module nine. Module 7 Neurons are the

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

This is a practice test for biology 101 test 2. You should also review all lectures and practice writing questions for each lecture set. You will also want to take advantage of the test banks under the “Lessons” tab in Angel. In addition to these sample questions and the test banks‚ you are advised to study the diagrams from all chapters and be able to label main structures. 1) The function of the rough endoplasmic reticulum(RER) is: a) Digestion b) Support c) DNA isolation d)
