Elephant's Trunk (other)
An elephant trunk or elephant's trunk is the Elephant#Trunk, proboscis/nose of an elephant. An elephant's trunk contains 8 pairs of muscles (and 150,000 muscle fascicles) and can be about feet long. An African elephant's trunk has a diameter of about at the tip, with nostril diameter of . The phrase may also refer to other things considered similarly shaped, including: * Elephant trunk (astronomy), a type of formation of interstellar matter. * The Elephant's Trunk nebula, a specific nebula, also in astronomy. * Elephant Trunk Hill, a landmark and tourist attraction in Guilin, Guangxi, China. * A funnel cloud * Elephant trunk snake, a species of snake.

Elephant
Elephants are the largest existing land animals. Three living species are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. They are the only surviving members of the family Elephantidae and the order Proboscidea. The order was formerly much more diverse during the Pleistocene, but most species became extinct during the Late Pleistocene epoch. Distinctive features of elephants include a long proboscis called a trunk, tusks, large ear flaps, pillar-like legs, and tough but sensitive skin. The trunk is used for breathing, bringing food and water to the mouth, and grasping objects. Tusks, which are derived from the incisor teeth, serve both as weapons and as tools for moving objects and digging. The large ear flaps assist in maintaining a constant body temperature as well as in communication. African elephants have larger ears and concave backs, whereas Asian elephants have smaller ears, and convex or level backs. Elephants ...

Muscle Fascicles
A muscle fascicle is a bundle of skeletal muscle fibers surrounded by perimysium, a type of connective tissue. Structure Muscle cells are grouped into muscle fascicles by enveloping perimysium connective tissue. Fascicles are bundled together by epimysium connective tissue. Muscle fascicles typically only contain one type of muscle cell (either type I fibres or type II fibres), but can contain a mixture of both types. Function In the heart specialized cardiac muscle cells transmit electrical impulses from the atrioventricular node (AV node) to the Purkinje fibers – fascicles, also referred to as bundle branches. These start as a single fascicle of fibers at the AV node called the bundle of His that then splits into three bundle branches: the right fascicular branch, left anterior fascicular branch, and left posterior fascicular branch. Clinical significance Myositis may cause thickening of the muscle fascicles. This may be detected with ultrasound scans. Mu ...

Elephant Trunk (astronomy)
Elephant trunks (more formally, cold molecular pillars) are a type of interstellar matter formations found in molecular clouds. They are located in the neighborhood of massive O type and B type stars, which, through their intense radiation, can create expanding regions of ionized gas known as H II regions. Elephant trunks resemble massive pillars or columns of gas and dust, but they come in various shapes, lengths, and colors. Astronomers study elephant trunks because of their unique formation process and use 2-D and 3-D simulations to try to understand how this phenomenon occurs. Formation O type and B type stars are a classification of stars that strongly emit ultraviolet (UV) radiation. The UV radiation causes the surrounding cloud of hydrogen gas to ionize, forming H II regions. The gas does not ionize evenly throughout the cloud, therefore there are clumps of denser gas scattered throughout the cloud. These dense clumps are called evaporating gaseous globules (EGGs), an ...

Elephant Trunk Hill
The Elephant Trunk Hill () is a hill, landmark and tourist attraction in Guilin, Guangxi, China. It is not only one of the major tourist attractions of Guilin, an international tourist city, but also the symbol of Guilin, which uses elephant trunk mountain and osmanthus flower as its city emblem. he Elephant Trunk Hill formerly known as Li Mountain, also known as Yi mountain, Chen Shui mountain, referred to as elephant mountain. In 1986, Xiang Shan park was built in accordance with Xiang Shan mountain. The main part of the park is Xiang Shan mountain and water moon, the ancient building Yun Feng temple, the love island, and the Ming dynasty building Pu Xian pagoda. Elephant Trunk Hill is the symbol of the city of Guilin. It got its name because it looks like an elephant drinking water. The round opening that would be under the elephant’s trunk is known as Water-Moon Cave because at night the reflection of the moon can be seen through the arch and it looks as if it is und ...

Funnel Cloud
A funnel cloud is a funnel-shaped cloud of condensed water droplets, associated with a rotating column of wind and extending from the base of a cloud (usually a cumulonimbus or towering cumulus cloud) but not reaching the ground or a water surface. A funnel cloud is usually visible as a cone-shaped or needle like protuberance from the main cloud base. Funnel clouds form most frequently in association with supercell thunderstorms, and are often, but not always, a visual precursor to tornadoes. Funnel clouds are visual phenomena, these are not the vortex of wind itself. "Classic" funnel clouds If a funnel cloud touches the surface the feature is considered a tornado, although ground level circulations begin before the visible condensation cloud appears. Most tornadoes begin as funnel clouds, but some funnel clouds do not make surface contact and these cannot be counted as tornadoes from the perspective of a naked eye observer, even as tornadic circulations of some intensity alm ...

Elephant Trunk Snake
The elephant trunk snake or the Javan file snake (''Acrochordus javanicus''), is a species of snake in the family Acrochordidae, a family which represents a group of primitive non-venomous aquatic snakes. Description The elephant trunk snake possesses a wide and flat head, and its nostrils are situated on the top of the snout. Those head particularities confer to ''A. javanicus'' a certain resemblance with boas. However, its head is only as wide as its body. Females are bigger than males, and the maximum total length (including tail) of an individual is . The dorsal side of the snake's body is brown, and its ventral side is pale yellow. The skin is baggy and loose giving the impression that it is too big for the animal. The skin is covered with small rough adjacent scales. The skin is also used in the tannery industry. The top of the head has no large shields, but instead is covered with very small granular scales. There are no ventral scales. The body scales are in about 120 ...

Elephant's Toothpaste
Elephant's toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide () using potassium iodide (KI) or yeast and warm water as a catalyst. How rapidly the reaction proceeds will depend on the concentration of hydrogen peroxide. Because it requires only a small number of ingredients and makes a "volcano of foam", this is a popular experiment for children to perform in school or at parties. The experiment is also known as the "marshmallow experiment", but is unrelated to the psychological Stanford marshmallow experiment. Explanation Description About 50 ml of concentrated (>12%) hydrogen peroxide is first mixed with liquid soap or dishwashing detergent. Then, a catalyst, often around 10 ml potassium iodide solution or catalase from baker's yeast, is added to make the hydrogen peroxide decompose very quickly. Hydrogen peroxide breaks down into oxygen and water. As a small amount of hydrogen peroxide generates a large volume of oxygen, the oxyge ...

Hydrogen Peroxide
Hydrogen peroxide is a chemical compound with the formula . In its pure form, it is a very pale blue liquid that is slightly more viscous than water. It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use, and in higher concentrations for industrial use. Concentrated hydrogen peroxide, or " high-test peroxide", decomposes explosively when heated and has been used as a propellant in rocketry. Hydrogen peroxide is a reactive oxygen species and the simplest peroxide, a compound having an oxygen–oxygen single bond. It decomposes slowly when exposed to light, and rapidly in the presence of organic or reactive compounds. It is typically stored with a stabilizer in a weakly acidic solution in a dark bottle to block light. Hydrogen peroxide is found in biological systems including the human body. Enzymes that use or decompose hydrogen peroxide are classified as peroxidases. Properties The boiling poi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
