Navel
The navel (clinically known as the umbilicus, commonly known as the belly button or tummy button) is a protruding, flat, or hollowed area on the abdomen at the attachment site of the umbilical cord. All placental mammals have a navel, although it is generally more conspicuous in humans. Structure The umbilicus is used to visually separate the abdomen into quadrants. The umbilicus is a prominent scar on the abdomen, with its position being relatively consistent among humans. The skin around the waist at the level of the umbilicus is supplied by the tenth thoracic spinal nerve (T10 dermatome). The umbilicus itself typically lies at a vertical level corresponding to the junction between the L3 and L4 vertebrae, with a normal variation among people between the L3 and L5 vertebrae. Parts of the adult navel include the "umbilical cord remnant" or "umbilical tip", which is the often protruding scar left by the detachment of the umbilical cord. This is located in the center of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umbilicus (mollusc)
The umbilicus of a shell is the axially aligned, hollow cone-shaped space within the whorls of a coiled mollusc shell. The term umbilicus is often used in descriptions of gastropod shells, i.e. it is a feature present on the ventral (or under) side of many (but not all) snail shells, including some species of sea snails, land snails, and freshwater snails. The word is also applied to the depressed central area on the planispiral coiled shells of ''Nautilus'' species and fossil ammonites. (These are not gastropods, but shelled cephalopods.) In gastropods The spirally coiled whorls of gastropod shells frequently connect to each other by their inner sides, during the natural course of its formation. This results in a more or less solid central axial pillar, known as the columella. The more intimate the contact between the concave side of the whorls is, the more solid the columella becomes. On the other hand, if this connection is less intense, a hollow space inside the whorls may re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umbilicus (plant)
''Umbilicus'' is a genus of over ninety species of flowering plants in the family Crassulaceae. Many of its species have been given synonyms under different genera such as '' Rosularia'', ''Cotyledon'', and ''Chiastophyllum''. However, those that remain in ''Umbilicus'' are listed below: *'' Umbilicus chloranthus'' (called green Venus' navel) *'' Umbilicus chrysanthus'' (called Venus' navel) *'' Umbilicus erectus'' (called reniform Venus' navel) *'' Umbilicus horizontalis'' (called horizontal navelwort) *'' Umbilicus intermedius'' (called intermediate navelwort) *'' Umbilicus oppositifolius'' (called gold drop) (also as ''Chiastophyllum o.'') *''Umbilicus rupestris'' (called navelwort) ;Other (unnamed) species *'' Umbilicus aetneus'' (Tornab) *'' Umbilicus affinis'' (Schrenk) *'' Umbilicus aizoon'' (Fenzl) *'' Umbilicus albido-opacus'' (Carlström), sometimes referred to as opacus. *'' Umbilicus alpestris'' (Karelin and Kirilov) *'' Umbilicus botryoides'' (Hochstetter) ...

Umbilicus Urbis Romae
The ''Umbilicus Urbis Romae'' ()—"Navel of the City of Rome"—was the symbolic centre of the city from which, and to which, all distances in Ancient Rome were measured. It was situated in the Roman Forum where its remnants can still be seen. These remains are located beside the Arch of Septimius Severus and the Vulcanal, behind the Rostra. Originally covered in marble, the ''Umbilicus'' is now a forlorn-looking brick core some 2 metres high and 4.45 metres in diameter. History Roman legend related that Romulus, when he founded the city, had a circular pit dug in the Forum. The first fruits of the year were thrown into this pit as a sacrifice and all new citizens of Rome had to throw in a handful of dirt from their place of origin. The ''Mundus'' (Latin, "world"), known only from literary sources, was an underground structure considered a gate to the underworld. It may be that the ''Umbilicus Urbis Romae'' was the external (above ground) part of the subterranean ''Mundus''. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
