Myasthenia gravis (MG)
|
|
Myasthenia gravis (MG) Myasthenia gravis is a neuromuscular disease in which there is a failure of the nerves' ability to stimulate and control the actions of certain muscles, especially those of the eye, face, lips, tongue, throat, and neck.
RELATED TERMS--------------------------------------
Disease
Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.
Eye
The organ of sight. The eye has a number of components. These components include but are not limited to the cornea, iris, pupil, lens, retina, macula, optic nerve, choroid and vitreous.
Tongue
The muscular organ attached to the floor of the mouth. Used to speak, chew, swallow and taste.
SIMILAR TERMS--------------------------------------
Myasthenia gravis
A chronic disease characterized by muscular weakness and fatigue.
PREVIOUS AND NEXT TERMS--------------------------------------
Migraine
A vascular headache associated with changes in the size of the arteries within and outside of the brain. A migraine begins when hyperactive nerve cells send out impulses to the blood vessels, causing constriction, followed by the dilation of these vessels and the release of prostaglandins, serotonin, and other inflammatory substances that cause the pulsation to be painful. Migraine is a genetic disorder that is inherited. A migraine causes mild to severe pain and lasts from 4 hours up to a week. Migraines usually occur 2 to 4 times per month.
Macular degeneration
Damage or breakdown of the macula, which is an area in the back of the eye that controls central vision. It may be caused by injury or aging; and while it does not progress to total blindness, patients with macular degeneration require special optical aids to enlarge distant and near objects.
Monocular vision
A condition in which one eye is blind, or in which one eye refuses to register images in co-ordination with the better eye.
Multiple sclerosis
An auto-immune disease of the central nervous system, mainly affecting young adults, whose origin is unknown. It damages nerve fiber insulation (myelin) in a random and patchy manner, causing a wide range of neurological defects. It is characterized clinically by symptoms that typically abate spontaneously in the early years of the disease but often get gradually worse in later years.
Muscular dystrophy
An inherited condition that is due to a gene on the X chromosome. It is therefore called a sex-linked gene. It results in the inability to produce a vital muscle chemical resulting in muscle wastage, stumbling, then inability to walk and death by the age of about 20.
Myasthenia gravis (MG)
Myopia
Also known as nearsightedness, myopia is a refractive error caused by an eyeball that is too long to focus light on the retina or a cornea which is too steeply curved. In these cases light focuses instead in front of the retina. People with myopia are usually able to see close objects well, but objects in the distance—such as highway signs or writing on a chalkboard—appear blurred.
Meniere's Disease
A disorder or condition of the inner ear. The major symptoms that cause most of our difficulty are characterized by abnormal sensation of movement (vertigo), loss of hearing, and noises or ringing (tinnitus) in one or both ears. was first described by French physician Prosper Meniere in 1861.
Myositis
Muscular soreness due to inflammation that often occurs 1-2 days after unaccustomed exercise. Often referred as DOMS (Delayed onset muscle soreness).
Metatarsus
The metatarsus consists of the five long bones of the foot, which are numbered from the medial side (ossa metatarsalia I.-V.); each presents for examination a body and two extremities. These are analogous to the metacarpals of the hand.
Metacarpals
Five long bones of the hand, running from the wrist to the fingers.
