Is a rare condition, categorised by tongue enlargement which will eventually create a crenated border in relation to the embrasures between the teeth.
|
|
The base of the shell is convex. The aperture is oval. The thin outer lip is crenated on the margin. The thin columella is slightly thickened above and attenuates abruptly to the front.
|
|
The margin is white, crenated by the striae. The columella striated transversely oblique to the end of the siphonal canal, and somewhat tuberculated. Inside it is purple, marked by the ribs. Montagu, G. (1803).

Bean, W. J. (1936) Trees and shrubs hardy in Great Britain, 7th edition, Murray, London, vol. 2 They have been described as strongly crenated or deeply incised by relatively few teeth (four to seven); some herbarium specimens, however, show shallowly indented margins.bioportal.naturalis.nl specimen WAG.

Crenated tongue is a descriptive term for the appearance of the tongue when there are indentations along the lateral borders (the sides), as the result of compression of the tongue against the adjacent teeth. The oral mucosa in the area of crenation is usually of normal color, but there may be erythema (redness) if exposed to a high degree of friction or pressure. Crenated tongue is usually asymptomatic and harmless. It is not a disease as such, but usually results from habits where the tongue is pressed against the lingual surfaces (the side facing the tongue) of the dental arches, or from any cause of macroglossia (enlarged tongue), which in itself has many causes such as Down syndrome.

It is smooth inside, crenated on the outside by spiral sculpture, thin and sharp. The columella is vertical, straight, lightly excavated toward the flat parietal wall. The inner lip is very thin and narrow and smooth. Henry Suter (1913): Manual of the New Zealand Mollusca; Government of New Zealand, Wellington, N.Z.

The body whorl is globose, convex below and has a rounded periphery. The aperture is rounded. The outer lip is slightly crenated by the spiral ribs, dark-margined, and beveled to an edge. It is thickened by a heavy white rim inside, which is slightly notched at the periphery, but elsewhere is smooth.
|
|
The outer lip is convex, thin, crenated on the outside by the spiral sculpture, with a shallow sinus below the suture. The columella is subvertical, almost straight, with 2 rounded short plaits above, absent in young examples. The inner lip is thin and narrow, spreading over the straight parietal wall. The operculum is unknown.

Some of these were quite white; some, either white or of the usual > colour were rough on the surface and with crenated margins. Fleming and his research scholar Daniel Merlin Pryce pursued this experiment but Price was transferred to another laboratory in the early 1928. After a few months of working alone, Fleming was joined by a new scholar Stuart Craddock.

The upper angle is acute, continuing nearly to the apex. The whorls are concave above, slightly excavated around the periphery, a little convex beneath. They are encircled by numerous unequal spiral threads, the larger ones beaded, the smaller irregularly crenated by rather decided incremental striae. The base of the shell is radiately striate, with about 8 to 12 smooth spirals, their interstices without secondary riblets.

Ranunculus lapponicus, the Lapland buttercup, is distributed all over the arctic, with the exception of northern and eastern Greenland. It is a low, prostrate plant with a creeping, underground stem (rhizome) which sends out long stalks and shoots bearing the flowers. The leaves are deeply tripartite, forming 3 lobes which are toothed or crenated. The flowers are yellow, solitary, generally having 6 (8) petals that are distinctly longer than the sepals.
|
|
The aperture is higher than wide, slightly oblique and quadrangular. The umbilicus is very deep, rather cylindrical, bordered by a deeply crenated white marginal rib, with a narrower beaded cingulus just outside it. This is a compact, depressed little shell, with diamond-shaped aperture, showing in fresh specimens a slight trace of pearl within. Adams describes the color as spotted with brown in transverse series, with transverse whitish lines, and a wide subsutural white band.

The cause is unknown. Geographic tongue does not usually cause any symptoms, and in those cases where there are symptoms, an oral parafunctional habit may be a contributory factor. Persons with parafunctional habits related to the tongue may show scalloping on the sides of the tongue (crenated tongue). Some suggest that hormonal factors may be involved, because one reported case in a female appeared to vary in severity in correlation with oral contraceptive use.

The pods contain many seeds small flattened seeds that are winged at both ends. It is similar to Cercidiphyllum japonicum, but can be distinguished by a combination of the following characteristics: C. magnificum is a smaller tree that typically has only a single main trunk (vs. large, canopy-forming, with multiple trunks); the leaves are more deeply crenated; the follicles have partially dehisce, with slightly recurved tips (vs. follicles fully dehiscing and strongly recurving tips); grows at a higher elevation, rarely co-occurring with C. japonicum.

The rose grows one to four flowers per stem that are in diameter. The bloom has been described as pink, dark pink, or fuchsia-colored in the style of old roses or resembling a peony. The petals are firm, which allows the flower to stay in shape in rain, the inner petals are sometimes whirled or quartered, and petals often have a thin light border and are sometimes crenated. The shrub is very thorny, branches only below flowers, and has large green to dark green foliage.

In (d) the RBCs are rendered crenated from a hypertonic solution Crenation is also used to describe a feature of red blood cells. These erythrocytes look as if they have projections extending from a smaller central area, like a spiked ball. The crenations may be either large, irregular spicules of acanthocytes, or smaller, more numerous, regularly irregular projections of echinocytes. Acanthocytes and echinocytes may arise from abnormalities of the cell membrane lipids or proteins, or from other disease processes, or as an ex vivo artifact.

The epithet crenatus means with crenations (wavy-toothed) and refers to the crenated stem margins. The subspecies epithet kimnachii honours Myron Kimnach (1922-2018), a botanist mainly working with epiphytic cacti and Crassulaceae, and for many years working at the University of California, Berkeley and Huntington Gardens. Kimnach was director of the Huntington Botanical Gardens for 25 years and editor of the Cactus and Succulent Society of America's Journal, and Managing Editor of its peer-reviewed, technical yearbook, Haseltonia for ten years.Cactus and Succulent Society of America, 2007 Convention Speakers, Cactus Lectures, Myron Kimnach.

The gooseberry is a straggling bush growing to 1.5 metres (5 feet) in height and width, the branches being thickly set with sharp spines, standing out singly or in diverging tufts of two or three from the bases of the short spurs or lateral leaf shoots. The bell- shaped flowers are produced, singly or in pairs, from the groups of rounded, deeply crenated 3 or 5 lobed leaves. The fruits are berries, smaller in wild gooseberries than the cultivated varieties, but often of good flavour. The berries are usually green, but there are red (to purple), yellow, and white variants.

The lesions are located on the mucosa, usually bilaterally in the central part of the anterior buccal mucosa and along the level of the occlusal plane (the level at which the upper and lower teeth meet). Sometimes the tongue or the labial mucosa (the inside lining of the lips) is affected by a similarly produced lesion, termed morsicatio linguarum and morsicatio labiorum respectively. There may be a coexistent linea alba, which corresponds to the occlusal plane, or crenated tongue. The lesions are white with thickening and shredding of mucosa commonly combined with intervening zones of erythema (redness) or ulceration.

Acanthocytosis can be seen in: acute or chronic anemia, hepatitis A, B, and C, hepatorenal syndrome, hypopituitarism, malabsorption syndromes, and malnutrition Acanthocytosis secondary to malnourishment, such as anorexia nervosa and cystic fibrosis, remits with resolution of the nutritional deficiency. Acanthocyte-like cells may be found in hypothyroidism, after splenectomy, and in myelodysplasia. Acanthocytes should be distinguished from echinocytes, which are also called 'burr cells', which although crenated are dissimilar in that they have multiple, small, projecting spiculations at regular intervals on the cell membrane. Burr cells usually imply uremia, but are seen in many conditions, including mild hemolysis in hypomagnesemia and hypophosphatemia, hemolytic anemia in long- distance runners, and pyruvate kinase deficiency.

The hard, well- burnt red or black ware bears incisions, stamps and impressions, which were finally filled with a white substance, probably made of bones or lime. The earlier pottery shows geometrical motifs, in the second and third phase S- and Z-shaped hooks appear, which were most probably abstract representations of animals with a symbolic meaning in the community´s cosmology.L. Dietrich, O. Dietrich, Wietenberg ohne Mykene? Gedanken zu Herkunft und Bedeutung der Keramikverzierung der Wietenberg-Kultur. Prähistorische Zeitschrift 86, 1, 2011, 67-84. Rotbav 4-5: The Noua Settlement Crenated scapula from Rotbav, Transylvania, Romania At the beginning of the 15th century BC, after the last phase of the Wietenberg Culture, a sudden change in the development of the settlement appeared.

Diagram of a crenated leaf Crenation (from modern Latin crenatus meaning 'scalloped or notched', from popular Latin crena meaning 'notch') in botany and zoology, describes an object's shape, especially a leaf or shell, as being round-toothed or having a scalloped edge. The descriptor can apply to objects of different types, including cells, where one mechanism of crenation is the contraction of a cell after exposure to a hypertonic solution, due to the loss of water through osmosis. In a hypertonic environment, the cell has a lower concentration of solutes than the surrounding extracellular fluid, and water diffuses out of the cell by osmosis, causing the cytoplasm to decrease in volume. As a result, the cell shrinks and the cell membrane develops abnormal notchings.

A para-functional habit or parafunctional habit is the habitual exercise of a body part in a way that is other than the most common use of that body part. The term is most commonly used by dentists, orthodontists, or maxillofacial specialists to refer to para-functional uses of the mouth, tongue and jaw. Oral para-functional habits may include bruxism (tooth-clenching and/or grinding), tongue tension ("tongue thrusting"), fingernail biting, pencil or pen chewing, mouth breathing, and any other habitual use of the mouth unrelated to eating, drinking, or speaking. Crenated tongue is a descriptive term for when scalloping develops on the lateral margins of the tongue as a result of habitual forcing of the tongue against the teeth.

It follows the Renaissance pattern of design on four floors: a hallway floor giving access to the palace from the fondamenta is surmounted by two Piano nobiles and a fourth story above them: :- the primo piano nobile, typical of Venetian neo-Renaissance style, is made of decorated columns and eight monofora windows of which four are component of an open loggia with balcony, this floor is hosting magnificent ceremonial rooms; :- the "secondo piano nobile" (secondary floor) has four monofora windows surrounding a large quadrifora closed loggia, it hosts more intimate reception spaces; :- the fourth story is of much simpler exterior design, it has eight square windows without applied decoration. The "U"-shaped back facade is made of two paralleled wings surrounding a large garden ending onto the back canal with a richly decorated crenated wall with arched gates to the Chiesa degli Ognissanti.

Spur cells may refer synonymously to acanthocytes, or may refer in some sources to a specific subset of 'extreme acanthocytes' that have undergone splenic modification whereby additional cell membrane loss has blunted the spicules and the cells have become spherocytic ('spheroacanthocyte'), as seen in some patients with severe liver disease.Mentzer WC. Spiculated cells (echinocytes and acanthocytes) and target cells. UpToDate (release: 20.12- C21.4) Acanthocytosis can refer generally to the presence of this type of crenated red blood cell, such as may be found in severe cirrhosis or pancreatitis, but can refer specifically to abetalipoproteinemia, a clinical condition with acanthocytic red blood cells, neurologic problems and steatorrhea. This particular cause of acanthocytosis (also known as abetalipoproteinemia, apolipoprotein B deficiency, and Bassen-Kornzweig syndrome) is a rare, genetically inherited, autosomal recessive condition due to the inability to fully digest dietary fats in the intestines as a result of various mutations of the microsomal triglyceride transfer protein (MTTP) gene.
