As Jeff’s doctors diagnosed‚ Jeff’s condition is caused by a mutation of a sodium channel‚ SCNA4. The official name for Jeff’s condition is hyperkalemic periodic paralysis. Hyperkalemic periodic paralysis is a disorder that causes sudden onsets of extreme muscle weakness or paralysis (Hyperkalemic Periodic Paralysis). Hyperkalemic periodic paralysis is so rare that only around 1 in 200‚000 people (Hyperkalemic Periodic Paralysis). Also since hyperkalemic periodic paralysis is an inherited condition;

The two main processes involved in muscle contraction are cross-bridge cycling and the length-tension relationship‚ which normally function to maximize contraction in the muscle. Beginning with the activation of a motor unit‚ the ions flow from the motor unit towards the muscle fibers that it innervates by the motor neuron in the same way as a normal muscle would. However since the tissue is damaged‚ the force that is generated by these muscle fibers will not be as great‚ leaving the fibers less

When one is getting ready to throw a pitch‚ there is 5 phase to complete a proper throw. The five phases of a throw are the windup‚ early cocking‚ cocking‚ acceleration‚ and the follow-through. (Hamill & Knutzen)‚ It should be notated that is the wind up phase there is little shoulder activity involved. In the early cocking phase‚ the lead off arm is in a potion of 90 degrees and in a position of abduction and introduces external rotation. As the player transitions into the cocking phase‚ the muscle

Anatomy and body type plays a significant role in determining the proper weightlifting strategy; there is no one weightlifting plan that would work for all members in a group‚ not only because people have different physical traits‚ but also different diet and living habits. There are three major body types: Ectomorph‚ endomorph and mesomorph. People who are described as Ectomorphs usually have lean muscle mass; they have small frames and do not gain weight easily‚ and therefore‚ have a slim appearance

How will Gene Doping effect the sports industry? Gene Doping is a different type of gene therapy that has caused a lot of controversy in the past 6-7 years due to the capability of what this method of doping could do. Gene doping therapy was started at Harvard in 1999 and was specifically used to get a substantial rise in the performance of athletes. This is done by genetically modifying cells to enhancing athletic performance. Gene therapy is done by using genes to help treat or stop diseases.

The muscle physiology of skeletal muscle was observed by using electrical‚ physical‚ and neural stimulations of an isolated gastrocnemius muscle from Rana pipiens. The gastrocnemius receives signals from the action potentials of the sciatic nerve. The muscle contraction is caused by the binding of a neurotransmitter once the action potential reaches the neuromuscular junction. Stimulation of the muscle and the sciatic nerve allows for recording and measuring of these properties. We observed twitch

For human beings‚ one of the most important evolutionary adaptations that have allowed us to reach the point we are now would be the structure and function of the prehensile hand. There are a few other animals‚ mostly other primates‚ who have hands with a similar structure to that of a human and who do make some use of tools as well‚ but not quite to the extent that humans are able to (3). Comparative research on the hand of several species with those of the human hand have not been able to pin down
