experiment is to examine the results of stimulation on a frog’s sciatic nerve by looking at its compound action potential‚ the conduction velocity‚ and by quantifying the total and absolute refractory period between the nerve at room and cold temperature. An oscilloscope‚ preamplifier‚ and stimulator were used to stimulate the frog’s nerve located in the nerve chamber. Threshold voltage was determined by stimulating the nerve at increasing voltages until a compound action potential resulted. Absolute

joint. The tight space between this fibrous band and the wrist bone is called the carpal tunnel. The median nerve passes through the carpal tunnel to receive sensations from the thumb‚ index‚ and middle fingers of the hand. Any condition that causes swelling or a change in position of the tissue within the carpal tunnel can squeeze and irritate the median nerve. Irritation of the median nerve in this manner causes tingling and numbness of the thumb‚ index‚ and the middle fingers - a condition known

Sarin Gas is one the most deadly and toxic gases that has no color and no scent. The formula for this chemical is C4H10FO2P or a more complicated formula or CH3P(=O)(F)(OCH(CH3)2) . This destructive weapon was innovated as a herbicide during the 193040s which is labeled as a nerve agent. Sarin is capable of causing the fatality of someone or the suffocating of a person by just inhaling a low concentration of Sarin gas. Sarin is considered a chiral molecule since it contains four chemical substituents connected to a tetrahedral phosphorus center

biological agents are found naturally in nature or cultured for use. Different types of Chemical agents: Nerve Agents: Source: A FOA Briefing Book on Chemical Weapons Nerve agents acquired their name because they affect the transmission of nerve impulses in the nervous system. They are stable‚ easily spread‚ highly toxic and have rapid effects when absorbed through the skin and respiratory track. Nerve agents can be manufactured by means of fairly simple chemical techniques. The materials are inexpensive

Introduction The specialty of the Ear‚ Nose and Throat (ENT) system is relatively young compared to certain medical practices. Even to function as a unified discipline‚ pioneers of the specialty had to wage a protracted struggle to surmount considerable hindrances. Initially confined to managing ear infections alone‚ the introduction of surgical intervention skills gradually led the specialty to adapt a unified approach. Furthermore‚ with improved technological advances‚ the specialty’s horizon

What are my first thoughts about this case study? • When I first read about Carla’s presentation into the clinic‚ it sounded like it was piriformis syndrome. Although rarely recognized‚ piriformis syndrome appears to be a common cause of buttock and leg pain as a result of injury to the piriformis muscle. Symptoms are aggravated by prolonged hip flexion‚ adduction‚ and internal rotation‚ in the absence of low back or hip findings (Barton‚ 1991). Tonley et al. (2010) stated piriformis syndrome
