conclusion is that there is an effect outside of the heating effect. The effects of the changes produced by high intensity sound upon the central nervous system has been investigated. The results show that nerve cells are particularly sensitive to ultrasonics‚ while blood vessels and nerve fibers are much more resistant. A study of the therapeutic effect of ultrasonics shows that the heat which is produced plays the major role. However‚ ultrasonics also produces a mechanical effect. Ultrasonics

the glamorized world. Mairs strongly feels that "[she has not] lost anything in the course of this calamitous disease" (37)‚ known as Multiple Sclerosis‚ a disease that deteriorates the nerves and interferes with brain and body communication because the immune system has eaten away the protective covering on the nerve cells. To assert her confidence‚ Mairs initiates her essay with a strong‚ simple term to define herself: "a cripple" (37). She wants society to "wince" (37) in order to portray that

Minerals Calcium and phosphorous are major structural elements in bones and teeth. Calcium is needed for the muscles‚ helping in the relaxation and constriction of blood vessels to regulate blood flow‚ assisting with the transmission of nerve impulses and aiding in muscle contraction. Phosphorus is necessary for the structure of cell membranes and vital to energy production and storage in the body. Iron is necessary for the transportation of oxygen throughout the body‚ as well as energy

compounds prevent blood clotting. *Thromboses - Coagulate blood and foster clot formation throughout the circulatory system. *Haemolysis - Destroy red blood cells. *Cytolysins - Destroy white blood cells. *Neurotoxins - Block the transmission of nerve impulses to muscles‚ especially those associated with the diaphragm and breathing. Every snake has a different amount of the aforementioned agents its venom‚ hence the differing levels of toxicity. Throughout this report‚ the examination of the venom

parasympathetic nerves‚ which have only a modulatory function on the contractile activity. Sympathetic innervation originates from postganglionic fibers of the hypogastric plexus and it has an inhibitory effect on the motor function‚ making connections with neurons of the enteric nervous system‚ which in turn sends fibers to smooth muscle cells‚ inhibiting the contraction. On the other hand‚ parasympathetic fibers‚ which originate from the sacral plexus (S2–S4) and run into the pudendal nerve‚ send preganglionic

computer screen. Notice that your index finger is extended and your other fingers are curled into your palm. How did your hand know to do that? It all began in your brain‚ the starting point for an important chain of communication. Your brain ordered nerve cells‚ to activate muscles in your hand and fingers. In this instance‚ your muscles responded‚ and your fingers moved. In a person afflicted with Amyotrophic Lateral Sclerosis (ALS)‚ there is a break in the chain of communication. The motor neurons

The action of ANS-related drugs on smooth muscle Introduction In the following experiment‚ the key objective is to compare the mechanical changes in tonic force by longitudinal smooth muscle after the addition of different concentrations of the drugs noradrenaline and acetylcholine. Peristalsis is the wave of muscle contractions that allow circular muscles to constrict the gut and longitudinal muscles to shorten it in an attempt to move the food bolus towards the rectum.

individuals who had recovered from polio decades earlier. After recovering from polio‚ some survivors find themselves afflicted again‚ facing a serious condition called post-polio syndrome. PPS is a condition in the nervous system that affects muscles and nerves. What are the symptoms of Post-Polio Syndrome? Symptoms of post-polio tend to show up in a patient gradually. There may be long periods of time when symptoms are stabilized and no sign of increased muscle weakness occurs. The symptoms of PPS

less viscous. Muscle fibre micro tears: During exercise‚ your muscles are put under stress to the point that tiny tears occur in the muscle fibres. These are what micro tears are causes by swelling in the muscle tissue in that cause pressure on the nerve endings and pain. Training is the only way to improve if the body has sufficient fuel and rest in order to repair this micro tears‚ making the muscles a little bit stronger than it was before.
