Diseases and Disorders of Muscular System in Humans
Muscle illness is any disease that impacts the human muscle system. Neck pain is among the most common of all grievances that bring individuals to the medical professional’s office.
In any given year, about one in five adults will experience neck pain. That’s a lot of pain in the neck! Not all of them are due to muscular disorders, however, a number of them are. Following are the few common muscular disorders and diseases.
1.Muscle Strain
A muscle strain is an injury in which muscle fibers tear as a result of overstretching. A muscle strain is also frequently called a pulled muscle or torn muscle. Depending on the degree of injury to muscle fibers, a muscle strain can vary from mildly to very agonizing.
Besides discomfort, typical symptoms include tightness and bruising in the area of the stretched muscle. Hamstring strain is very typical in track and field athletes. In sprinters, for example, about one-third of injuries are hamstring injuries. Having a previous hamstring injury puts an athlete at increased danger for having another one.
2.Muscular Dystrophy
Muscular dystrophy (MD) is a group of muscle diseases identified by the creation of non-functional muscle proteins that weakens muscles and impairs proper function. Particularly the proteins dystrophin and the dystrophin protein complexes are altered and nonfunctional, unable to accompany actin filaments.
This leads to disturbances of mechanical stabilization and calcium concentration regulation within the sarcomeres, changing the capability of filaments to bind and trigger contraction. The development of the disease consists of the death of muscle tissue.
3.Carpal Tunnel Syndrome
People whose job includes repeated flexing of their wrist (typing, house painting, writing) may establish tingling and/or discomfort in their thumb, index, and middle fingers in addition to the weakness of motions of the thumb, especially, grasping a thing.
The primary nerve for finely managed thumb movements travels through a bony/ligamentous canal on the bottom of the wrist. Repetitive flexing movements may irritate and thicken the ligament over the “tunnel” through the carpal (wrist) bones trapping and compressing the nerve.
4.Rhabdomyolysis
Rhabdomyolysis is a muscle disease that causes the breakdown of skeletal muscle. This breakdown causes myoglobin release in the bloodstream– a protein that stores oxygen in the muscles. Excessive myoglobin in the blood can cause kidney damage.
Reasons for rhabdomyolysis include injury, infection and swelling, medications, contaminants, and genetic and metabolic disorders. Treatment depends on the seriousness of symptoms and the presence of problems. Kidney damage from rhabdomyolysis may not be reversible.
5.Myasthenia gravis
” Muscular weakness, extensive”. This is an autoimmune disease that involves the production of antibodies that hinder nerves promoting muscle contractions. Face and neck muscles are the most certainly affected, manifesting as sagging eyelids, double vision, trouble swallowing, and general fatigue. There is no real paralysis of muscles included, however a fast fatiguing of function.
6.Parkinson’s Disease
Parkinson’s disease is a degenerative disorder of the central nervous system that mainly affects the muscular system and motion. 4 motor signs and symptoms are thought about specifying in Parkinson’s disease: muscle trembling (shaking), muscle rigidness, slowness of motion, and postural instability.
Trembling is the most common and apparent symptom, and it most often occurs in a limb that is at rest, so it vanishes throughout sleep or when the patient moves the limb voluntarily. Trouble strolling eventually develops, and dementia prevails in the sophisticated phases of the illness. Anxiety prevails, too.
7.Cardiomyopathy
Cardiomyopathy also referred to as heart muscle disease is a kind of progressive disease impacting cardiac muscle. It triggers the heart to become abnormally enlarged, thickened, and/or stiff, making it harder for the heart muscle to pump blood efficiently. Eventually, this may lead to cardiac arrest and accumulation of blood into the lungs and other parts of the body. Cardiomyopathy can also trigger unusual heart rhythms and heart valve problems.
8.Dermatomyositis (DM)
DM is an uncommon inflammatory muscle disease affecting individuals of any age or sex, although it’s more often seen in women. Common symptoms of DM include a distinctive rash, muscle weakness, and inflamed, and pain in muscles. Much like other inflammatory myopathies, the cause is unidentified, and while there is no cure, the condition can be handled with medications and other treatments.
