Glabella (gastropod)
''Glabella'' is a genus of small tropical and warm-water sea snails, marine gastropod molluscs in the family Marginellidae, the margin snails. Taxonomy It is debatable whether it is justified to distinguish this genus from ''Marginella'' s. str. without a comprehensive phylogenetic hypothesis of the family. However the two genera cannot be objective synonyms because ''Marginella glabella'' (Linnaeus, 1758) is not one of the species originally included in ''Glabella''. Species According to the World Register of Marine Species (WoRMS), the following species with valid names are included within the genus ''Glabella'' : * '' Glabella adansoni'' Kiener, 1834 * '' Glabella ansonae'' Clover, 1976 * '' Glabella bellii'' G.B. Sowerby II, 1846 * '' Glabella bifasciata'' (Lamarck, 1822) * '' Glabella davisiana'' Marrat, 1877 * '' Glabella denticulata'' Link, 1807 * '' Glabella faba'' (Linnaeus, 1758) * '' Glabella fumigata'' (Gofas & Fernandes, 1994) * '' Glabella harpaeformis'' G.B.

Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...

Glabella Faba
The glabella, in humans, is the area of skin between the eyebrows and above the nose. The term also refers to the underlying bone that is slightly depressed, and joins the two brow ridges. It is a cephalometric landmark that is just superior to the nasion. Etymology The term for the area is derived from the Latin , meaning 'smooth, hairless'. In medical science The skin of the glabella may be used to measure skin turgor in suspected cases of dehydration In physiology, dehydration is a lack of total body water, with an accompanying disruption of metabolic processes. It occurs when free water loss exceeds free water intake, usually due to exercise, disease, or high environmental temperature. Mil ... by gently pinching and lifting it. When released, the glabella of a dehydrated patient tends to remain extended ("tented"), rather than returning to its normal shape.
