Auricle (anatomy)
The auricle or auricula is the visible part of the ear that is outside the head. It is also called the pinna (Latin for "wing" or "fin", plural pinnae), a term that is used more in zoology. Structure The diagram shows the shape and location of most of these components: * ''antihelix'' forms a 'Y' shape where the upper parts are: ** ''Superior crus'' (to the left of the ''fossa triangularis'' in the diagram) ** ''Inferior crus'' (to the right of the ''fossa triangularis'' in the diagram) * ''Antitragus'' is below the ''tragus'' * ''Aperture'' is the entrance to the ear canal * ''Auricular sulcus'' is the depression behind the ear next to the head * ''Concha'' is the hollow next to the ear canal * Conchal angle is the angle that the back of the ''concha'' makes with the side of the head * ''Crus'' of the helix is just above the ''tragus'' * ''Cymba conchae'' is the narrowest end of the ''concha'' * External auditory meatus is the ear canal * ''Fossa triangularis'' is the depres ...

Atrium (heart)
The atrium ( la, ātrium, , entry hall) is one of two upper chambers in the heart that receives blood from the circulatory system. The blood in the atria is pumped into the heart ventricles through the atrioventricular valves. There are two atria in the human heart – the left atrium receives blood from the pulmonary circulation, and the right atrium receives blood from the venae cavae of the systemic circulation. During the cardiac cycle the atria receive blood while relaxed in diastole, then contract in systole to move blood to the ventricles. Each atrium is roughly cube-shaped except for an ear-shaped projection called an atrial appendage, sometimes known as an auricle. All animals with a closed circulatory system have at least one atrium. The atrium was formerly called the 'auricle'. That term is still used to describe this chamber in some other animals, such as the ''Mollusca''. They have thicker muscular walls than the atria do. Structure Humans have a four-chambered ...

Planarian
A planarian is one of the many flatworms of the traditional class Turbellaria. It usually describes free-living flatworms of the order Tricladida (triclads), although this common name is also used for a wide number of free-living platyhelminthes. Planaria are common to many parts of the world, living in both saltwater and freshwater ponds and rivers. Some species are terrestrial and are found under logs, in or on the soil, and on plants in humid areas. The triclads are characterized by triply branched intestine and anteriorly situated ovaries, next to the brain. Today the order Tricladida is split into three suborders, according to their phylogenetic relationships: Maricola, Cavernicola and Continenticola. Formerly, the Tricladida was split according to habitats: Maricola, which is marine; Paludicola which inhabits freshwater; and Terricola, which is land-dwelling. Planaria exhibit an extraordinary ability to regenerate lost body parts. For example, a planarian split lengt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Primula Auricula
''Primula auricula'', often known as auricula, mountain cowslip or bear's ear (from the shape of its leaves), is a species of flowering plant in the family Primulaceae, that grows on basic rocks in the mountain ranges of central Europe, including the western Alps, Jura Mountains, the Vosges, the Black Forest and the Tatra Mountains. Description It is an evergreen perennial growing to tall by wide. The leaves are obovate and stalkless, with a cartilaginous edge, all growing in a basal rosette, and sometimes covered in a mealy white bloom. The yellow flowers grow in clusters on long stalks. The specific epithet ''auricula'' means "ear-shaped", and refers to the shape of the leaves. Taxonomy A recent study split the species into two, '' Primula lutea'' and ''P. auricula'', with the former being found further south and east (Apennines, Carpathians, Balkans, and the southern and eastern Alps). Prior to this study, ''P. lutea'' had been considered synonymous with ''P. auricula' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trilobite
Trilobites (; meaning "three lobes") are extinct marine arthropods that form the class Trilobita. Trilobites form one of the earliest-known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period () and they flourished throughout the lower Paleozoic before slipping into a long decline, when, during the Devonian, all trilobite orders except the Proetida died out. The last extant trilobites finally disappeared in the mass extinction at the end of the Permian about 252 million years ago. Trilobites were among the most successful of all early animals, existing in oceans for almost 270 million years, with over 22,000 species having been described. By the time trilobites first appeared in the fossil record, they were already highly diversified and geographically dispersed. Because trilobites had wide diversity and an easily fossilized exoskeleton, they left an extensive fossil record. The stu ...

Auricle Ensemble
The Auricle Ensemble is a chamber ensemble based in Scotland. It was created by a co-operative of professional musicians working in the UK in 2007 and has become known for its diverse programming. The group is based in the West End of Glasgow, with rehearsal space and administration based at St Bride's Church, Glasgow. The Auricle Ensemble performs throughout the year as a resident ensemble in the St Bride's at 7 series, and repeats these concerts across Scotland, in places such as the University of Edinburgh, Falkirk Town Hall, Byre Theatre St. Andrews, Isle of Bute, Wigtown Book Festival. It performs annually at Glasgow's West End Festival and Edinburgh Festival, and received critical attention with its tour of Arnold Schoenberg's Pierrot Lunaire. The ensemble's family concert with its orchestral octet performances for young audiences narrated by Balamory actress, Juliet Cadzow has been performed in festivals and venues across Scotland.

1231 Auricula
1231 Auricula ( ''prov. designation'': ) is a carbonaceous background asteroid from the central regions of the asteroid belt, approximately in diameter. It was discovered on 10 October 1931, by German astronomer Karl Reinmuth at the Heidelberg Observatory. The likely elongated C-type asteroid has a rotation period of 3.98 hours. It was named after the flowering plant '' auricula'' and indirectly honors astronomer Gustav Stracke. Orbit and classification Based on recent HCM-analyses, ''Auricula'' is a non-family asteroid that belongs to the main belt's background population. On its osculating Keplerian orbital elements, it is located in the Eunomia region (), where the prominent family of stony asteroids is located. It orbits the Sun in the central main-belt at a distance of 2.4–2.9 AU once every 4 years and 4 months (1,593 days; semi-major axis of 2.67 AU). Its orbit has an eccentricity of 0.09 and an inclination of 11 ° with respect to the ecliptic. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
