Myotonia

In short, these goats seize up when they get excited due to a quirk in their genetics, called myotonia congenita . ❋ Gadget42 (2010)

The reason that fainting goats faint is that they have a hereditary genetic disorder called myotonia congenita. ❋ Unknown (2009)

Vanderbilt University School of Medicine, Nashville, Tennessee, United States of America Myotonic dystrophy types 1 and 2 (DM1 and DM2) are forms of muscular dystrophy that share similar clinical and molecular manifestations, such as myotonia, muscle weakness, cardiac anomalies, cataracts, and the presence of defined RNA-containing foci in muscle nuclei. ❋ Morgan A. Sammons Et Al. (2010)

Myotonic dystrophy types 1 and 2 (DM1 and DM2) are forms of muscular dystrophy that share similar clinical and molecular manifestations, such as myotonia, muscle weakness, cardiac anomalies, cataracts, and the presence of defined RNA-containing foci in muscle nuclei. ❋ Morgan A. Sammons Et Al. (2010)

The names refer specifically to myotonia congenita, a condition in which the muscle cells experience prolonged contraction when the goat is startled. ❋ The Eternal Postdoc (2007)

He had been labeled with a number of interesting diagnoses, such as chorea, epilepsy, myotonia, hysteria, and neurasthenia. ❋ Unknown (1896)

Since losing convertibility of the dollar to gold, we have been subject to shock after shock, economic incidents of myotonia, of increasing rate and severity. ❋ Gadget42 (2010)

Female orgasm is a variable, transient peak sensation of intense pleasure, creating an altered state of consciousness, usually with an initiation accompanied by involuntary, rhythmic contractions of the pelvic striated circumvaginal musculature, often with concomitant uterine and anal contractions and myotonia that resolves the sexually induced vasocongestion (sometimes only partially), generally with an induction of well-being and contentment. ❋ Unknown (2010)

Myotonic dystrophy involves difficulty relaxing muscles (myotonia) and, as in other muscular dystrophies, progressive muscle weakness and wasting. ❋ Unknown (2010)

Myotonic dystrophy involves difficulty-relaxing muscles (myotonia) and, as in other muscular dystrophies, progressive muscle weakness and wasting. ❋ Unknown (2010)

Despite the different expansions within two apparently unrelated genes, both diseases share many common clinical manifestations, including myotonia, muscle weakness, cataract development, insulin resistance, and cardiac conduction defects. ❋ Morgan A. Sammons Et Al. (2010)

This is unlikely to be caused by muscular fatigue or myotonia for the following reasons. ❋ Anna Matynia Et Al. (2010)

Mbnl1 −/− mice display skeletal myotonia, muscle weakness, cataracts and possibly heart disease ❋ Anna Matynia Et Al. (2010)

Myotonic dystrophy (DM1) is a multi-system disorder characterized by muscle weakness, skeletal myotonia, cardiac conduction defects, ocular cataracts and cognitive and behavioral abnormalities ❋ Anna Matynia Et Al. (2010)

Second, myotonia exhibits a "practice effect" meaning that the failure of muscle relaxation after contraction decreases with even a short warm-up period of activity ❋ Anna Matynia Et Al. (2010)
