In the case of A.D.‚ a severe drop in blood pressure was noted‚ dropping from 110/72 to 90/60‚ as well as a decreased heart rate‚ from 86 to 54 beats per minute. As damage to the spinal nerve tracts occur‚ system vasomotor tone is often loss‚ leading to vasodilation‚ and a decrease in the venous return rate (Hung‚ 2009). These factors decrease cardiac output‚ thus decreasing the blood pressure and heart rate (Young‚ 2010). A drop in the heart rate and blood

Behterev‚ the term reflexology was found‚ yet still wasn’t widely used until the 1960’s. In the early 1900’s “Zone therapy” was discovered and its use in health care. Zone therapy came from building upon previous research by Sir Henry Head of the nervous system. Sir Henry Head had discovered that areas of skin which had increased sensitivity to pain (HyperAlgesia) have links to diseased internal organs. The nerves surrounding the organ and the skin were connected as they were from the same segment of

Research and treatments in the neurorehabilitation field are starting to excel. It was first thought that the central nervous system could not repair itself after an injury. It wasn’t until the 1970’s that research studies showed it had the ability to heal itself to some extent. Researchers ultimately wanted to know if there was a relationship between the central nervous system and cortical plasticity so this knowledge could be used to benefit patient recovery. One research included removing a

and damage to the perineurium. Most of the deformities occurring from Leprosy are in fact due to trauma or a secondary infection. In a Leprosy infection one of the first symptoms are anesthesia to heat and cold. Leprosy affects the peripheral nervous system by attacking the myelin sheath surrounding the axons which affects the reliability and speed of nerve impulses. In other words‚ the nerve fibers are no longer insulated and nerve impulses cannot be conducted efficiently. There are different types

far back as World War I this condition was referred to as "shell shock‚" in which there are similarities between reactions of soldiers who suffered concussions caused by exploding bombs or shells and those who suffered blows to their central nervous systems. A person may be describing as having acute stress disorder if other mental disorders or medical conditions do not provide a better explanation for the person’s symptoms. Symptoms include: * Lack of emotional responsiveness‚ a sense of numbing

there are billions of cells that are essential to living – these are called nerve cells. Nerve cells‚ also known as neurons‚ “are the basic information processing structures” (Stufflebeam). There are about 100 billion of these neurons in our nervous system and are the most essential cell in it. Located in brain as well as the spinal‚ there are different types of nerve cells; including: sensory neurons‚ motor neurons‚ and interneuron (Boeree). The neuron is a cell that is structured similarly to

A&P 1 Effects of Selected Drugs During anesthesia‚ there is a great amount of drugs used to suppress the pain that would occur to the body. There are some common drugs that are used. Alcohol‚ Aspirin‚ Lidocaine‚ Morphine‚ Ketamine‚ and Succinylcholine are all used during anesthesia. Each is used to interrupt the pain signals during surgeries. Without these medications‚ the body would not be able to withstand such trauma occurring to perform the procedure fully. For many years‚ men and women

Major causes are stroke‚ trauma‚ poliomyelitis‚ amyotrophic lateral sclerosis (ALS)‚ botulism‚ spina bifida‚ multiple sclerosis‚ and Guillain-Barré syndrome. Temporary paralysis occurs during REM sleep‚ and dysregulation of this system can lead to episodes of waking paralysis. Drugs that interfere with nerve function‚ such as curare‚ can also cause paralysis. Many causes of this are varied‚ and could also be unknown. Paralysis is caused by something being wrong with the nerves
