Death From Laughter
Death from laughter is a supposedly extremely rare form of death, usually resulting from either cardiac arrest or asphyxiation, that has itself been caused by a fit of laughter. Instances of death by laughter have been recorded from the times of ancient Greece to modern times. Usually, the phrase "dying from laughter" is used as a hyperbole. Pathophysiology Death may result from several pathologies that deviate from benign laughter. Infarction of the pons and the medulla oblongata in the brain may cause the pseudobulbar affect. Asphyxiation caused by laughter leads the body to shut down from the lack of oxygen. Laughter can cause atonia and collapse ("agelastic syncope"), which in turn can cause trauma. See also laughter-induced syncope, cataplexy, and Bezold–Jarisch reflex. Gelastic seizures can be due to focal lesions to the hypothalamus. Depending upon the size of the lesion, the emotional lability may be a sign of an acute condition, and not itself the cause o ...

Chrysippus Of Soli
Chrysippus of Soli (; grc-gre, Χρύσιππος ὁ Σολεύς, ; ) was a Greek Stoic philosopher. He was a native of Soli, Cilicia, but moved to Athens as a young man, where he became a pupil of the Stoic philosopher Cleanthes. When Cleanthes died, around 230 BC, Chrysippus became the third head of the Stoic school. A prolific writer, Chrysippus expanded the fundamental doctrines of Cleanthes' mentor Zeno of Citium, the founder and first head of the school, which earned him the title of the Second Founder of Stoicism. Chrysippus excelled in logic, the theory of knowledge, ethics, and physics. He created an original system of propositional logic in order to better understand the workings of the universe and role of humanity within it. He adhered to a deterministic view of fate, but nevertheless sought a role for personal freedom in thought and action. Ethics, he thought, depended on understanding the nature of the universe, and he taught a therapy of extirpating the un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laughter-induced Syncope
Laughter-induced syncope is an unusual but recognized form of situational syncope (fainting) likely to have a similar pathophysiological origin to tussive syncope. One reported case occurred while a patient was watching the television show '' Seinfeld'', and was given the name Seinfeld syncope. There are few case reports of this syndrome in the literature. Patients, as in this case, might present initially to the emergency department, and laughter should be considered among the numerous differentials for syncope. Laughter-induced syncope should not be confused with cataplexy, a sudden loss of muscle tone triggered by strong emotions, particularly laughter. Unlike syncope, there is no loss of consciousness in cataplexy, which affects 65-75% of patients with narcolepsy Narcolepsy is a long-term neurological disorder that involves a decreased ability to regulate sleep–wake cycles. Symptoms often include periods of excessive daytime sleepiness and brief involuntary sleep e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Fig
The fig is the edible fruit of ''Ficus carica'', a species of small tree in the flowering plant family Moraceae. Native to the Mediterranean and western Asia, it has been cultivated since ancient times and is now widely grown throughout the world, both for its fruit and as an ornamental plant.''The Fig: its History, Culture, and Curing'', Gustavus A. Eisen, Washington, Govt. print. off., 1901 ''Ficus carica'' is the type species of the genus ''Ficus'', containing over 800 tropical and subtropical plant species. A fig plant is a small deciduous tree or large shrub growing up to tall, with smooth white bark. Its large leaves have three to five deep lobes. Its fruit (referred to as syconium, a type of multiple fruit) is tear-shaped, long, with a green skin that may ripen toward purple or brown, and sweet soft reddish flesh containing numerous crunchy seeds. The milky sap of the green parts is an irritant to human skin. In the Northern Hemisphere, fresh figs are in season from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donkey
The domestic donkey is a hoofed mammal in the family Equidae, the same family as the horse. It derives from the African wild ass, ''Equus africanus'', and may be classified either as a subspecies thereof, ''Equus africanus asinus'', or as a separate species, ''Equus asinus''. It was domesticated in Africa some years ago, and has been used mainly as a working animal since that time. There are more than 40 million donkeys in the world, mostly in underdeveloped countries, where they are used principally as draught or pack animals. While working donkeys are often associated with those living at or below subsistence, small numbers of donkeys or asses are kept for breeding or as pets in developed countries. A male donkey is known as a ''jack'' or ''jackass'', a female is a ''jenny'' or ''jennet'', and an immature donkey of either sex is a ''foal''. Jacks are often mated with female horses (mares) to produce '' mules''; the less common hybrid of a male horse (stallion) and ...

Stoicism
Stoicism is a school of Hellenistic philosophy founded by Zeno of Citium in Athens in the early 3rd century BCE. It is a philosophy of personal virtue ethics informed by its system of logic and its views on the natural world, asserting that the practice of virtue is both necessary and sufficient to achieve (happiness, ): one flourishes by living an ethical life. The Stoics identified the path to with a life spent practicing the cardinal virtues and living in accordance with nature. The Stoics are especially known for teaching that "virtue is the only good" for human beings, and that external things, such as health, wealth, and pleasure, are not good or called in themselves ('' adiaphora'') but have value as "material for virtue to act upon". Alongside Aristotelian ethics, the Stoic tradition forms one of the major founding approaches to virtue ethics. The Stoics also held that certain destructive emotions resulted from errors of judgment, and they believed people shou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aphrodite
Aphrodite ( ; grc-gre, Ἀφροδίτη, Aphrodítē; , , ) is an ancient Greek goddess associated with love, lust, beauty, pleasure, passion, and procreation. She was syncretized with the Roman goddess . Aphrodite's major symbols include myrtles, roses, doves, sparrows, and swans. The cult of Aphrodite was largely derived from that of the Phoenician goddess Astarte, a cognate of the East Semitic goddess Ishtar, whose cult was based on the Sumerian cult of Inanna. Aphrodite's main cult centers were Cythera, Cyprus, Corinth, and Athens. Her main festival was the Aphrodisia, which was celebrated annually in midsummer. In Laconia, Aphrodite was worshipped as a warrior goddess. She was also the patron goddess of prostitutes, an association which led early scholars to propose the concept of "sacred prostitution" in Greco-Roman culture, an idea which is now generally seen as erroneous. In Hesiod's ''Theogony'', Aphrodite is born off the coast of Cythera from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeuxis (painter)
Zeuxis (; grc-gre, Ζεῦξις) (of Heraclea) was a Greek painter who flourished during the 5th century BCE and became famous for his ability to imitate nature and especially still life with his art. Life and work Zeuxis was an innovative Greek painter. Although his paintings have not survived, historical records state they were known for their realism, small scale, novel subject matter, and independent format. His technique created volumetric illusion through manipulating light and shadow, a change from the usual method of filling in shapes with flat color. Preferring small scale panels to murals, Zeuxis also introduced genre subjects (such as still life) into painting. He contributed to the composite method of composition, and may have originated an approach to, and thus influenced the concept of the ideal form of the nude, as described by art historian Kenneth Clark. As the story goes, according to Cicero, Zeuxis could not find a woman beautiful enough to pose as Helen of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerebellum
The cerebellum (Latin for "little brain") is a major feature of the hindbrain of all vertebrates. Although usually smaller than the cerebrum, in some animals such as the mormyrid fishes it may be as large as or even larger. In humans, the cerebellum plays an important role in motor control. It may also be involved in some cognitive functions such as attention and language as well as emotional control such as regulating fear and pleasure responses, but its movement-related functions are the most solidly established. The human cerebellum does not initiate movement, but contributes to coordination, precision, and accurate timing: it receives input from sensory systems of the spinal cord and from other parts of the brain, and integrates these inputs to fine-tune motor activity. Cerebellar damage produces disorders in fine movement, equilibrium, posture, and motor learning in humans. Anatomically, the human cerebellum has the appearance of a separate structure attached to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emotional Lability
In medicine and psychology, emotional lability is a sign or symptom typified by exaggerated changes in mood or affect in quick succession. Sometimes the emotions expressed outwardly are very different from how the person feels on the inside. These strong emotions can be a disproportionate response to something that happened, but other times there might be no trigger at all. The person experiencing emotional lability usually feels like they do not have control over their emotions. For example, someone might cry uncontrollably in response to any strong emotion even if they do not feel sad or unhappy. Emotional lability is seen or reported in various conditions including borderline personality disorder, histrionic personality disorder, post-traumatic stress disorder, hypomanic or manic episodes of bipolar disorder, and neurological disorders or brain injury (where it is termed pseudobulbar affect), such as after a stroke. It has sometimes been found to have been a harbinger, or earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypothalamus
The hypothalamus () is a part of the brain that contains a number of small nuclei with a variety of functions. One of the most important functions is to link the nervous system to the endocrine system via the pituitary gland. The hypothalamus is located below the thalamus and is part of the limbic system. In the terminology of neuroanatomy, it forms the ventral Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position prov ... part of the diencephalon. All vertebrate brains contain a hypothalamus. In humans, it is the size of an Almond#Nut, almond. The hypothalamus is responsible for regulating certain Metabolism, metabolic biological process, processes and other activities of the autonomic nervous system.

Lesion
A lesion is any damage or abnormal change in the tissue of an organism, usually caused by disease or trauma. ''Lesion'' is derived from the Latin "injury". Lesions may occur in plants as well as animals. Types There is no designated classification or naming convention for lesions. Since lesions can occur anywhere in the body and the definition of a lesion is so broad, the varieties of lesions are virtually endless. Generally, lesions may be classified by their patterns, their sizes, their locations, or their causes. They can also be named after the person who discovered them. For example, Ghon lesions, which are found in the lungs of those with tuberculosis, are named after the lesion's discoverer, Anton Ghon. The characteristic skin lesions of a varicella zoster virus infection are called '' chickenpox''. Lesions of the teeth are usually called dental caries. Location Lesions are often classified by their tissue types or locations. For example, a "skin lesion" or a " b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
