Handout Lab 5 - Cranial Nerves: Assessment of Functions INTRODUCTION The central nervous system (CNS) consists of the brain and the spinal cord. The CNS receives sensory information from other parts of the body or the body’s external environment and transmits motor information to other parts of the body by way of the peripheral nervous system (PNS). The PNS of the human includes 31 pairs of spinal nerves and 12 pairs of cranial nerves. Some nerves contain only motor nerve fibers (efferent fibers);

Germen chemist Dr. Gerhard Schrader was given a task to develop a pesticide. In just two years tabun was born‚ it had extremely high toxicity and was the first of the substances later referred to as nerve agents. A factory was built and produced during the years of 1942-1945 12‚000 tons of the chemical warfare agent tabun was made; in which the allies took large quantities of tabun at the end of the war. Even though Hitler and his army were losing the war‚ Schrader and his co-workers synthesized

Autism: A Neurobiological Disorder Abstract Autism is a neurobiological disorder that effects about 1 and 1000 children that are born. There cause of Autism is still unknown. As of right now‚ there is no cure for autism‚ only some of its symptoms. Nevertheless‚ with proper care and medication children and adults that suffer from autism can live a full productive life.

Guts‚ and Brains Seminar Summary During the seminar “Bugs‚ guts and brains: How gut microbiota shapes your mind and body” on November 7‚ Physiologist from UC Davis‚ Dr. Helen Raybould discussed how gut microbes in humans and animals affects neurophysiology based primarily on the foods we eat and the genes expressed in the gut. There is an intersection between micro and host physiology that affects the overall health and behavior of the host. To understand this‚ the neural pathways by which macronutrients

Photocatalytic degradation of methylene blue using TiO2 nanoparticles Nupur Mittal Chemical Engineering‚ IIT (BHU) Varanasi. Abstract: The aim of this research is to reduce the pollution caused by methylene blue dye in waste water coming from textile industries. For this purpose‚ TiO2 nanoparticles are made as they show good photocatalytic activity in degradation of dyes into harmless products. Synthesis is done using titanium butoxide and 2-propanol. The particles formed were a little larger

Impulse and Momentum Lab Part I: As the first lab of the Physics 2 curriculum‚ our class completed a lab experiment that introduced us students to a new concept that would be a foundation to the future topics that we learn in this class. In this lab activity‚ we used a lab cart on a flat track to compare the collision of the cart with a force sensor with and without the plunger during different trials. The materials that we would need for this activity are a lab cart on a flat track‚ a timer
