-plexia, -plexias, -plexies, -plexy, -plectic, -plexic +

(Greek: stroke, wound; used in medicine to denote "a condition resulting from a stroke")

apoplectic
Relating to, suffering from, or predisposed to apoplexy.
apoplexy (s), apoplexies (pl) (noun forms)
1. A term for a "stroke", a cerebrovascular accident (CVA), often associated with loss of consciousness and paralysis of various parts of the body.
2. Sudden impairment of neurological function, especially that resulting from a cerebral hemorrhage; a stroke.
3. Any acute clinical event, related to impairment of cerebral circulation, which lasts longer then twenty-four hours; brain attack.
4. A sudden effusion of blood into an organ or tissue.
5. A fit of extreme anger; rage.
6. Etymology: apoplexy comes from the Greek apoplexia, "a seizure", in the sense of being struck down.

In Greek plexe is "a stroke". The ancients believed that anyone suffering a stroke; or any sudden incapacity, had been struck down by the gods.

A "sudden fit of paralysis and dizziness", from Old French apoplexie or directly from Late Latin apoplexia; from apo-, "off" + plessein, "hit".

cataplexy
A debilitating medical condition in which a person suddenly feels weak and collapses at moments of strong emotion; such as, laughter, anger, fear, or surprise.

When such collapsing results, people with cataplexy may injure themselves.

Laughter and other emotions trigger a reflex in people which can bring many of the muscles of the body to the point of collapse.

The phenomenon can be measured by sending electric signals through the muscles and gauging their response. In cataplexy, what is known as the H-reflex, a neurological pathway that causes muscle contractions, virtually disappears.

Cataplexy often happens to people who have narcolepsy, a disorder in which there is great difficulty remaining awake during the daytime.

The word cataplexy comes from the Greek kata, meaning "down" + plexis, meaning "a stroke" or "seizure" or "a falling-down seizure".

electroplexy
The immediate effects produced by the passage of an electric current through any part of the body; such as, painful stimulation of nerves or tetanic contractions of muscles.

Tetanic contractions refers to the fusion of a number of simple spasms into an apparently smooth, continuous effort.

neuroplexia
A reference to a network of nerve cells or fibers.
neuroplexus
A plexus or network of nerve cells or fibers.

A plexus is an interlacing network, as of nerves, blood vessels, or lymphatic vessels.

pagoplexia
Frostbite; damage to tissues as the result of exposure to very low environmental temperatures.
phrenoplexia
A clinical syndrome known in the early part of the 19th century as ecstasy (a trance state in which ideas of dedication and complete surrender occupy almost the entire field of consciousness).
pseudoapoplexy
A condition resembling apoplexy, but without cerebral hemorrhage.
selenoplexia
A stroke resulting from an acute inhalation exposure to selenium (usually in the form of selenium dioxide or hydrogen selenide) which primarily results in respiratory effects with irritation of the mucous membranes in the nose and throat, producing coughing, nosebleeds, dyspnea (difficulty breathing), bronchial spasms, bronchitis, and chemical pneumonia.

There may also be gastrointestinal effects including vomiting and nausea; cardiovascular effects; neurological effects; such as, headaches and malaise; and irritation of the eyes.
