Neuromuscular junction

Myasthenia gravis is a chronic autoimmune disease that targets the neuromuscular junction resulting in impaired impulse transmission and skeletal muscle weakness. The muscular weakness may exacerbate during periods of activity while improving after periods of rest, occurring with various severities. Muscles that control the eyes, eyelids, facial expression, swallowing, and talking can also be affected. Symptoms are presented as drooping of the eyelids, called ptosis, blurred or double vision,…

Myasthenia Gravis is considered an “autoimmune neuromuscular disease” that is categorized by the different amounts of weakness of the skeletal muscles in the body. The cause of Myasthenia Gravis is a flaw in the transmission of the nerve impulses to the muscles in the body. When normal communication between nerves and muscles are distributed at the neuromuscular junction, Myasthenia Gravis occurs. In normal humans, when an impulse travels down a nerve, the nerve then releases a neurotransmitter…

Introduction Myasthenia gravis is a neuromuscular autoimmune disorder that affects the skeletal muscles in the body. This disorder is mainly characterized by periods of weakness in the body. The Latin meaning for myasthenia gravis is grave muscle weakness (Lewis 2007). In the United States the prevalence rate is 14 per 100,000 (Lewis 2007) myasthenia gravis can affect any age, but normally it affects people over the age of 50 (Lewis 2007) The mortality rate from myasthenia gravis…

Myasthenia gravis is a neurological disorder that affects the immune system and causes chronic muscle weakness in the skeletal muscles of the human body. The name myasthenia gravis means "grave muscle weakness". A strong indication of myasthenia gravis is muscle weakness that heighten during periods of physical activity and decrease after resting periods. Muscles like those that control eye and eyelid movement, facial expression, eating, speaking, breathing and neck and limb movements can all…

Introduction Monoclonal gammopathy of undetermined significance (MGUS) is condition in which there is too much of a protein called monoclonal protein, or M protein, in the blood. MGUS can cause there to be too many cells in your blood and not enough space for healthy cells. This condition increases your risk of cancer. What are the causes? The cause of this condition is not known. What increases the risk? You are more likely to develop this condition if: You are African American. You are 50…

Myasthenia gravis is a neuromuscular disorder or autoimmune disorder. An autoimmune disorder occurs when the immune system mistakenly attacks its own healthy tissue. Neuromuscular disorders involve the muscles and the nerves that control them. With myasthenia gravis, the body produces antibodies that block the muscle cells from receiving messages (neurotransmitters) from the nerve, which causes weakness of the voluntary muscles. Therefore, fewer receptors are available for stimulation, resulting…

Introduction: The importance of this research paper is to clarify, discuss and understand the issues that impacts beast meat quality in poultry. The three main issues the poultry industry has been faced with is white striping of breast muscle, woody breast, and deep pectoral myopathy. These issues is not a medical or health issue for humans’ consumptions but, a quality issue of consumption. The white strip of breast muscle is strips parallel to the muscle fiber. It is mostly found in breast…

Inclusion Body Myositis is a neuro-muscular disease affecting people over fifty, mostly males, is characterized by progressive muscle weakness and atrophy in key muscles in the arms (forearm flexors) and the legs (quadriceps), resulting in severe disability. IBM is generally a slowly progressive disease and life expectancy isn’t significantly affected. Ted was diagnosed with IBM in 2012 when he was 68 years old, but his muscle biopsy showed that he has had it 10 to 15 years prior to the…

Morgellons disease is an interesting disease that is very rare and often hard to diagnose correctly. This particular disease is very hard to clarify. The symptoms can be different from varying patients. However, general symptoms include crawling senses under the skin, itching, black dots in the skin, thread-like fibers coming from the skin or underneath the skin, joint pain, trouble sleeping, panic attacks, memory loss and skin rashes. Not all patients have these symptoms but the two that almost…

muscle fibers which have at least one neuromuscular junction. A neuromuscular junction is the area of the skeletal muscle fiber that is innervated by a motor neuron (motor nerve). It plays a key role in body movement and breathing along with our nervous system. The synaptic knob, motor end plate, and the synaptic cleft are all key parts of the neuromuscular junction. The synaptic knob of an axon connects with a skeletal muscle fiber to form the neuromuscular junction. The synaptic knob has…
