is myotonic dystrophy the same as muscular dystrophy?

Muscular dystrophy (MD) refers to a group of nine genetic diseases that cause progressive weakness and degeneration of muscles used during voluntary movement. Myotonic dystrophy (DM) is one of the muscular dystrophies. It is the most common form seen in adults and is suspected to be among the most common forms overall.

The structure of skeletal muscle cells also makes them unique among muscle tissues. ... These stripes are caused by the regular arrangement of actin and myosin proteins within the cells into structures known as myofibrils.

A muscle cell is called a sarcomere. a myofibril are several sarcomeres connected to each other as a long strand. several of these myofibrils bunched together form a muscle fiber. ... YES, a muscle cell is a muscle fibre, they mean the same thing, but a muscle fibre really is not a muscle cell.

Muscular dystrophy (MD) is a group of genetic disorders that gradually weakens and damages the muscles. Multiple sclerosis (MS) is an immune-mediated disorder of the central nervous system that disrupts communication between the brain and body and within the brain itself.

The DMD gene is located on the X chromosome, so Duchenne muscular dystrophy is an X-linked disease and mostly affects males because they have only one copy of the X-chromosome.

Of the different types of cardiomyopathy, the most common type is ischemic cardiomyopathy. It occurs when coronary artery disease (also called ischemic heart disease) or a heart attack reduces blood flow to the heart, damaging the muscle. This condition is sometimes called dilated cardiomyopathy, or DM.

In short, the answer is yes — mFd is the same as uF- which is also the same as the symbol 'µ' as seen in 'µF'. Technically 'mfd' represents 'milliFarad' while 'uF' stands for 'microFarad' which is an order of magnitude smaller.

Polysaccharide storage myopathy (PSSM1) is characterized by the abnormal accumulation of the normal form of sugar stored in muscle (glycogen) as well as an abnormal form of sugar (amylase-resistant polysaccharide) in muscle tissue. By definition horses with PSSM1 have a distinctive genetic mutation in the gene.

In some cases, muscle twitching, pain, or atrophy will also occur with chronic alcoholic myopathy. Chronic myopathy can also result in occasional bouts of acute myopathy, with muscle pain and weakness and darkened urine occurring after the person binges on alcohol.

The eye muscles appear to be better equipped to maintain their muscle-nerve contacts and are thereby less affected. "While skeletal muscles are severely affected in ALS, eye muscles are far less affected than limb muscles.

Amyotrophic lateral sclerosis (ALS), also called classical motor neuron disease, affects both the upper and lower motor neurons. It causes rapid loss of muscle control and eventual paralysis. Many doctors use the term motor neuron disease and ALS interchangeably.

Neuromuscular diseases, such as myasthenia gravis (autoimmune neuromuscular disorder that causes muscle weakness) and multiple sclerosis (disease that affects the brain and spinal cord causing weakness, coordination, balance difficulties, and other problems), are other causes for muscle weakness that can occur in the ...

PSSM staat voor polysaccharide storage myopathy. Dit is groep spieraandoeningen waarbij suikermoleculen stapelen in de spiercellen wat leidt tot spierproblemen. Sinds kort wordt er door een laboratorium in Duitsland een nieuwe genetische test aangeboden om PSSM2 aan te tonen bij paarden.

Both MS and ALS are disabling. ALS (amyotrophic lateral sclerosis, Lou Gehrig's disease) and MS (multiple sclerosis) are not the same disease. They sometimes are confused because they have some similarities.

Skeletal muscle. ... Muscle fibers are in turn composed of myofibrils. The myofibrils are composed of actin and myosin filaments, repeated in units called sarcomeres, which are the basic functional units of the muscle fiber.

Duchenne muscular dystrophy is inherited in an X-linked recessive pattern. Males have only one copy of the X chromosome from their mother and one copy of the Y chromosome from their father. If their X chromosome has a DMD gene mutation, they will have Duchenne muscular dystrophy.

In this autosomal dominant disease, inclusion-body myopathy is associated with frontotemporal dementia and is caused by mutations in the valosin containing protein gene. This condition confirms that mutation of a shared protein can result in disease affecting both brain and muscle tissues.
