Suprapedal Gland
The suprapedal gland or mucous pedal gland is an anatomical feature found in some snails and slugs. It is a gland located inside the front end of the foot of gastropods.Barker G. M. (2001) "Gastropods on Land: Phylogeny, Diversity and Adaptive Morphology." in Barker G. M. (ed.):The biology of terrestrial molluscs. CABI Publishing, Oxon, UK, . 1-146, cited page: page 12. The term ''suprapedal'' means "above the foot". The function of this gland is to produce mucus. The gland opens on the front end of the sole, on the ventral side of the foot. The mucus produced by this gland becomes a thin layer covering the sole of the foot, and this helps the gastropod in moving. There are gland cells in the suprapedal gland. For example, in the suprapedal gland of the land snail ''Pomatias elegans'' there are three types of gland cells: cells producing mucoproteins, cells producing proteins and cells producing sulphated mucopolysaccharides. For example, the land slug '' Leidyula floridana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudunela Cornuta 5
''Pseudunela'' is a genus of minute sea slugs, acochlidians, shell-less marine (ocean), marine or temporary brackish or brackish gastropod mollusks in the clade Acochlidiacea. ''Pseudunela'' is the only genus in the family Pseudunelidae. ''Pseudunela'' is the type genus of the family Pseudunelidae.

Mucopolysaccharides
Glycosaminoglycans (GAGs) or mucopolysaccharides are long, linear polysaccharides consisting of repeating disaccharide units (i.e. two-sugar units). The repeating two-sugar unit consists of a uronic sugar and an amino sugar, except in the case of the sulfated glycosaminoglycan keratan, where, in place of the uronic sugar there is a galactose unit. GAGs are found in vertebrates, invertebrates and bacteria. Because GAGs are highly polar molecules and attract water; the body uses them as lubricants or shock absorbers. Mucopolysaccharidoses are a group of metabolic disorders in which abnormal accumulations of glycosaminoglycans occur due to enzyme deficiencies. Production Glycosaminoglycans vary greatly in molecular mass, disaccharide structure, and sulfation. This is because GAG synthesis is not template driven, as are proteins or nucleic acids, but constantly altered by processing enzymes. GAGs are classified into four groups, based on their core disaccharide structures. Hepa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arion Ater
Arion (; grc-gre, Ἀρίων; fl. c. 700 BC) was a kitharode in ancient Greece, a Dionysiac poet credited with inventing the dithyramb. The islanders of Lesbos claimed him as their native son, but Arion found a patron in Periander, tyrant of Corinth. Although notable for his musical inventions, Arion is chiefly remembered for the fantastic myth of his kidnapping by pirates and miraculous rescue by dolphins, a folktale motif. Origins Arion was a native of Methymna in Lesbos, and, according to some mythological accounts, a son of Cyclon or of Poseidon and the nymph Oncaea. All traditions about him agree in describing him as a contemporary and friend of Periander, tyrant of Corinth, so that he must have lived about BC 700. He appears to have spent a great part of his life at the court of Periander, but respecting his life and his poetical or musical productions, scarcely anything is known beyond the story of his escape from the sailors with whom he sailed from Sicily to Cor ...

Littorina
''Littorina'' is a genus of small sea snails, marine gastropod molluscs in the family Littorinidae, the winkles or periwinkles.WoRMS (2011). Littorina Férussac, 1822. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=138135 on 2011-04-15 These small snails live in the tidal zone of rocky shores. Overview In Europe there are about nine species in this genus, one of which is the rough periwinkle, '' Littorina saxatilis'' (Olivi, 1792). Another closely related (supposed) species ''Littorina tenebrosa'' (Montagu 1802) was thought to be distinct because of its different ecological requirements, but current studies have shown that it is not at all clear whether the two are indeed separate species or whether ''L. tenebrosa'' is perhaps merely an ecotype (an ecological form) of ''L. saxatilis''.Gosling, E.M.

Bithynia
Bithynia (; Koine Greek: , ''Bithynía'') was an ancient region, kingdom and Roman province in the northwest of Asia Minor (present-day Turkey), adjoining the Sea of Marmara, the Bosporus, and the Black Sea. It bordered Mysia to the southwest, Paphlagonia to the northeast along the Pontic coast, and Phrygia to the southeast towards the interior of Asia Minor. Bithynia was an independent kingdom from the 4th century BC. Its capital Nicomedia was rebuilt on the site of ancient Astacus in 264 BC by Nicomedes I of Bithynia. Bithynia was bequeathed to the Roman Republic in 74 BC, and became united with the Pontus region as the province of Bithynia et Pontus. In the 7th century it was incorporated into the Byzantine Opsikion theme. It became a border region to the Seljuk Empire in the 13th century, and was eventually conquered by the Ottoman Turks between 1325 and 1333.
