Syncope is a genus of microhylid frogs. Their common name is silent frogs (though species transferred from Chiasmocleis are called humming frogs). They occur in northern South America (Colombia, Ecuador, Peru, and Brazil, possibly Bolivia).
There are eight species:
Syncope may refer to one of the following:
In phonology, syncope (/ˈsɪŋkəpiː/; Greek: syn- + koptein "to strike, cut off") is the loss of one or more sounds from the interior of a word, especially the loss of an unstressed vowel. It is found both in synchronic analysis of languages and diachronics. Its opposite, whereby sounds are added, is epenthesis. A syncope rule has been identified in Tonkawa, an extinct American Indian language, whereby the second vowel of a word deletes if it is not adjacent to a consonant cluster or final consonant.
Synchronic analysis studies linguistic phenomena at one moment, usually the present. In modern languages, syncope occurs in inflection, poetry, and informal speech.
In languages such as Irish, the process of inflection can cause syncope.
For example :
It is interesting that if the present root form in Irish is the result of diachronic syncope, there is a resistance to synchronic syncope for inflection.
Syncope, also known as fainting, passing out and swooning, is defined as a short loss of consciousness and muscle strength, characterized by a fast onset, short duration, and spontaneous recovery. It is due to a decrease in blood flow to the entire brain usually from low blood pressure. Some causes have prodromal symptoms before the loss of consciousness occurs. These symptoms may include lightheadedness, sweating, pale skin, blurred vision, nausea, vomiting, and feeling warm, among others. Syncope may also be associated with a short episode of muscle twitching. If a person does not completely lose consciousness and muscle strength it is referred to as presyncope. It is recommended that presyncope be treated the same as syncope.
Causes range from non-serious to potentially fatal. There are three broad categories of causes: heart or blood vessel related, reflex also known as neurally mediated, and orthostatic hypotension. Issues with the heart and blood vessels are the cause in about 10% and typically the most serious while neurally mediated is the most common. Heart related causes may include an abnormal heart rhythm, problems with the heart valves or heart muscle and blockages of blood vessels from a pulmonary embolism or aortic dissection among others. Neurally mediated syncope occurs when blood vessels expand and heart rate decreases inappropriately. This may occur from either a triggering event such as exposure to blood, pain or strong feelings or a specific activity such as urination, vomiting, or coughing. This type of syncope may also occur when an area in the neck known as the carotid sinus is pressed. The final type of syncope is due to a drop in blood pressure from standing up. This is often due to medications that a person is taking but may also be related to dehydration, significant bleeding or infection.
