understand abnormality in the nerve that cause disorders. The objective of this study was to trigger a compound nerve action potentials (CAPs) and examine the effects of a stimulus voltage on a nerve and inspect their threshold‚ refractory period and also their velocity. Compound nerve action potentials (CAPs) are summed action potential of one nerve‚ one nerve consists of many neurons. We used the sciatic Lithobates pipiens nerve in this experiment‚ the sciatic nerve is long nerve‚ it extends from the buttocks

Introduction A nerve is an enclosed bundle of axons found in the peripheral nervous system (Easton 13). It is the pathway for electrochemical nerve impulses‚ which pass along axons of the peripheral organs. A neuron is a cell in the nervous system which plays many critical tasks like receiving sensory signals from the external and internal environments. Moreover‚ neurons join together these sensory responses to produce and transmit motor responses as a result of changes in membrane permeability

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

use of Nerve agents‚ and to a larger extent Chemical Weapons‚ is illegal according to United Nations Resolution 687 which passed in 1991. The production‚ stockpiling‚ and use of these weapons were banned by The Hague Convention of 1899 and the Geneva Protocol of 1925. All Nerve agents are fatal to the human body in the same way. Some are more potent‚ and some remain on the battlefield longer than others. Many factors play a role in how long a Nerve agent remains on the battlefield. Nerve agents come

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
