to be generated to gain additional orbital altitude. The impulse‚ sometimes called total impulse‚ is the product of thrust and the effective firing duration. A shoulder fired rocket such as the LAW has an average thrust of 600 lbs and a firing duration of 0.2 seconds for an impulse of 120 lbsec. The Saturn V rocket‚ used during the Apollo program‚ not only generated much more thrust but also for a much longer time. It had an impulse

system of the heart consists of specialized muscle cells that generate and send rhythmic electrical impulses to the myocardium in order for the heart to contract (Cardiac Conduction System‚ 2016). When there is the normal rhythm of the heart it is called sinus rhythm and any deviation from sinus rhythm is called an arrhythmia (Saladin‚ 2012). Electrocardiograms (ECG) record the electrical impulses and help determine when there are any abnormalities in the way the heart functions (Saladin‚ 2012).

temperature‚ are carried by A fibers. Motor impulses to skeletal muscles are also carried by A fibers. These types of impulses relay information about the external surroundings and how the body will respond to external stimuli. The speed with which these impulses are carried could reduce the incidence of injury to the body by allowing for a quick reaction to a stimulus. 3. Student answers will vary. Sample answer: Two factors that influence the speed with which an impulse is conducted are the diameter of the

Branches of the Axon Myelin Sheath Axon A Briefly describe the role each of the following play in neural communication: 1. Dendrite: branching neuron structures that receive neural impulses from other neurons and convey impulses toward the cell body 2. Axon: long tube like structure that conveys impulses away from the neurons cell body toward other neurons/muscles or glands 3. Cell Body: part of the neuron containing the cell nucleus as well as other structures that help the neuron carry

Civil War?”. People wonder what reasons and evidence there is to prove this idea of the battle. The Battle of Gettysburg in 1863 was a turning point of the Civil War because of how the south got discouraged‚ hardship set in‚ and the union gained momentum overall. One reason the Battle of Gettysburg was a turning point of the Civil War is how the south got discouraged. According to Document A‚ after 1863 (the battle)‚ the Confederates didn’t travel north anymore. The violence and destruction of
