- Myotonic dystrophy--the most common adult form of muscular dystrophy--is a chronic, progressive, and inherited neuromuscular condition presenting with multisystemic complications including distal muscle weakness, myotonia, hypersomnolence, early-onset cataracts, cardiac conduction abnormalities, and slurred speech and swallowing problems (Harper, 2001).

- Hypotonia, commonly known as floppy baby syndrome, is a state of low muscle tone[1] (the amount of tension or resistance to stretch in a muscle), often involving reduced muscle strength.

Myotonia congenita Back to TopSymptoms. The hallmark of this condition is myotonia -- the muscles are unable to quickly relax after contracting. For example, after a handshake, the person is only very slowly able to open and pull away his hand.

What is Hypertonicity? Hypertonicity is an increased tension of the muscles, meaning the muscle tone is abnormally rigid, hampering proper movement. This condition is the opposite of hypotonicity. Hypotonicity is a decreased tension in muscle tone. A lack of muscle tone inhibits proper movement as the muscle is not developed or is too soft to support the body.

IV fluids??? Mar 28, '08. Isotonic is a term for fluids with the same osmolality as the cell interior. Hypotonic is a term for solutions in which the solutes are less concentrated than the cells (= hypoosmolar). Hypertonic is a term for solutions with solutes more concentrated than cells (= hyperosmolar).

Hypertonicity Relevant terms include isotonicity, hypertonicity, and hypotonicity. In general, hypertonicity is a condition characterized by the presence of a greater degree of tone or tension. In cellular level, hypertonicity is a property of a solution wherein the amount of solutes is higher than that of another solution. A solution is also hypotonic when a solution (or a fluid) has greater osmotic pressure than the other solution (or fluid).

Eyelid Twitching | Causes | Treatment Eyelid Twitching Causes and Treatments . DEFINITION of Myokymia. Myokymia is the medical name for eyelid twitching. Myokymia is spontaneous contracture of the eyelid muscles, usually the orbicularis oculi muscle. Myokymia is usually unilateral (one eye only) and more often involves the lower eyelid instead of the upper. The condition is not serious and is usually self limiting.

Myotonic Dystrophy (DM) Myotonic Muscular Dystrophy (MMD) What is myotonic muscular dystrophy (MMD)? Myotonic muscular dystrophy (MMD) is a form of muscular dystrophy that affects muscles and many other organs in the body. The word myotonic is the adjective for the wordmyotonia, an inability to relax muscles at will.

Hypotonia in Infants Hypotonia in Infants. Hypotonia is reduced resistance to passive movement of joints. The deficits causing hypotonia can originate in the brain, spinal cord, peripheral nerves, neuromuscular junction, and muscle. The differential diagnosis of hypotonia is organized anatomically into central and peripheral causes.

Isotonic, Hypotonic, & Hypertonic Solutions Cells in Hypotonic Solutions Hypotonic comes from the Greek hypo, meaning under, and tonos, meaning stretching. In a hypotonic solution the total molar concentration of all dissolved solute particles is less than that of another solution or less than that of a cell.

- A hypotonic solution is a solution with a lower concentration of dissolved substances than is found inside the cell. If a cell is surrounded by hypotonic solution, then water will move INTO the cell by osmosis because there is a higher concentration of water outside the cell compared to inside. A cell in hypotonic solution will swell up and, if there is no cell wall, may burst.

- Myotonic dystrophy is a muscle condition that falls under the umbrella term ‘muscular dystrophy’. The muscular dystrophies all have three features in common; they are hereditary, they are progressive; and each causes a characteristic, selective pattern of muscle wasting and weakness.Myotonic dystrophy is the most common adult form of muscular dystrophy-thought to affect at least 1 in 8,000 people worldwide.owever, this is generally less noticeable after the early stages of myotonic dystrophy. The first muscles to be affected by weakness are those of the face, neck, hands, forearms, and feet. The large, weight-bearing muscles of the legs and thighs are much less affected.

Hypotonia Hypotonia, commonly known as floppy baby syndrome, is a state of low muscle tone, often involving reduced muscle strength. Hypotonia is not a specific medical disorder, but a potential manifestation of many different diseases and disorders that affect motor nerve control by the brain or muscle strength. Hypotonia is resistance to passive movement, whereas muscle weakness results in impaired active movement. Central hypotonia originates from the central nervous system, while peripheral hypotonia

What is the difference between hypertonic, hypotonic, and isotonic? they are all different types of solutions: hypotonic: a solution which contains more solute than solvent (example: a lot of salt(solute) dissolved in water(solvent)) hypertonic: a solution which contains more solvent than solute (example: purified water--there's almost no solute dissolved in the solvent(water))
