Interneurons: send information BETWEEN motor neurons and sensory neurons; found in the CNS‚ connect neurons. Nodes of Ranvier: a gap between two of the Schwann cells that make up an axon’s myelin sheath; serves as a point for generating a nerve impulse. Resting potential: the difference in electrical charge across the plasma membrane of a neuron. Sodium-potassium pump: the mechanism that uses ATP energy

Module 06 Case Study: Articulations and Nerve Tissue Part I— “Jill” Questions 1. What is the difference between a tendon and ligament? (1 point) --The difference between a tendon and a ligament is that a tendon attaches to muscle. (ie. muscle-bone‚ muscle-muscle‚ muscle- skin) A ligament‚ however‚ attaches to cartilage. (ie. cartilage-bone‚ cartilage-cartilage‚ bone-bone) 2. What bones form the articulation (joint) of the ankle? Did Jill most likely sprain or strain her ankle? Explain your

Chapter 2: Neurons and Glia 1. Introduction * Although there are many neurons in the human brain (about 100 billion)‚ glia outnumbers neurons by tenfold. 1:10 ratio. * Neurons are the most important cells for the unique functions of the brain. * Neurons sense changes in the environment‚ communicate these changes to other neurons‚ and command the body’s responses to these situations. * Glia‚ or glial cells‚ are thought to contribute to brain function mainly by insulating‚

Dada From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search For other uses‚ see Dada (disambiguation). Cover of the first edition of the publication Dada by Tristan Tzara; Zurich‚ 1917 Dada /ˈdɑːdɑː/ or Dadaism was an art movement of the European avant-garde in the early 20th century. Many claim Dada began in Zurich‚ Switzerland in 1916‚ spreading to Berlin shortly thereafter but the height of New York Dada was the year before in 1915.[1] To quote Dona Budd ’s The Language of

concept began with Robert Hooke’s seventeenth-century observation that slices of cork were made up of small units he called "cells.” Over the next 100 years‚ the cell theory emerged. It was formally (and independently) presented by Schleiden and Schwann in 1839‚ and clarified by Virchow a few years later. This theory has three principles: (1) All organisms are composed of one or more cells. (2) All life processes derive from the activities of cells. (3) All cells arise from preexisting cells.

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
