The Cardiovascular System: Intrinsic Conduction System 1. The intrinsic conduction system consists of __autorhythmic cardiac______ cells that initiate and distribute __impulses___ throughout the heart. 2. The intrinsic conduction system coordinates heart activity by determining the direction and speed of _heart depolarization___. This leads to a coordinated heart contraction. 3. List the functions for the following parts of the intrinsic conduction system: a. SA Node __initiates the depolarizing

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

Exercise 3: Neurophysiology of Nerve Impulses Worksheet Assignment Due: Week 4 Eliciting a Nerve Impulse Activity 1: Electrical Stimulation 1. Do you see any kind of response on the oscilloscope screen? No 2. What was the threshold voltage‚ or the voltage at which you first saw an action potential? The threshold voltage is at 3.0 V. 3. How does this tracing compare to the one that was generated at the threshold voltage? There was a slight increase. 4. What reason can you

Purpose The reason for this experiment is to prove that objects of different masses‚ when dropped from the same height‚ fall at the same velocity. Apparatus - 2 Marbles of different mass‚ one steel and one nylon - Dropping Mechanism with a lever to hold the marble and pull for drop - Bee Spi (measures velocity in kilometers per hour.) - Box to catch the marble on the way down Procedure The dropping mechanism was set up‚ with the BeeSpi attached to it at 26.5” from the lever that drops

symptoms expressed by my neighbor I would say it is very likely that she has damaged her oculomotor nerve. The oculomotor nerve innervates both the inferior rectus muscle and the levator palpebrae superioris. The inferior rectus muscle allows the eye to depress and abduct‚ if there were an injury to the oculomotor nerve it could cause the eye to retain this position. The levator palpebrae superioris allows the eyelid to elevate and damage to the nerve here would cause the inability to fully lift her

There are three main nerves in your hand radial nerve‚ median nerve‚ and ulnar nerve. Each one of these gives movement and feeling to different areas of the hand. The ulnar nerve is one of the three main nerves in your arm. It travels from your neck down into your hand. The most common place for this nerve is behind the inside part of the elbow. The radial nerve descends down the arm with in the triceps with in the upper arm. Then moves down the arm within the humerus also known as the radial

negatives of using a muscle building products like Creatine. Creatine obviously boost muscle building‚ but it comes with negatives. If not used properly it causes weight gain‚ and all of it is mostly water weight. So you have to know how to properly maintain your body if you’re going to use this supplement. However‚ I feel that the Pros outweigh the cons if used properly. Positives included added intensity in workouts to build more muscle mass‚ Enhanced athletic performance‚ and increased metabolism

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 about 2‚000 new compounds up until the end of the war‚ including sarin
