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

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

The Neolithic Revolution is a major turning point in human history. 3.

A sample of gas is confined to 30ml at a pressure of 6 atmospheres. When the pressure is changed to 3liters‚ what is the resulting pressure? 3. A gas occupies 30 L. When the gas is heated from 50C to 100C‚ what is the final volume? 4. In a lab‚ Neon vapor occupied a volume of 1 liter at STP‚ the volume was changed to 4 liter

Cardio Pulmonary Practical The main aim of the practical was to assess‚ what affects did light exercise have on the systolic and diastolic blood pressure‚ heart and respiration rate‚ tidal volume‚ minute volume and percentage of gas. The readings were taken before exercise‚ during exercise and after exercise. Blood pressure is defined as the amount of pressure exerted on the vessels walls‚ during blood flow. Blood pressure can be measured using a sphygmomanometer. The upper value indicates the

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
