Sinus may refer to:
The umbilical vein is a vein present during fetal development that carries oxygenated blood from the placenta into the growing fetus. The umbilical vein provides convenient access to the central circulation of a neonate for restoration of blood volume and for administration of glucose and drugs.
Arcus may refer to:
In the fetus, the ductus venosus shunts a portion of umbilical vein blood flow directly to the inferior vena cava. Thus, it allows oxygenated blood from the placenta to bypass the liver. Compared to the 50% shunting of umbilical blood through the ductus venosus found in animal experiments, the degree of shunting in the human fetus under physiological conditions is considerably less, 30% at 20 weeks, which decreases to 18% at 32 weeks, suggesting a higher priority of the fetal liver than previously realized. In conjunction with the other fetal shunts, the foramen ovale and ductus arteriosus, it plays a critical role in preferentially shunting oxygenated blood to the fetal brain. It is a part of fetal circulation.
A sinus venosus atrial septal defect is a type of atrial septal defect primarily associated with the sinus venosus.
The sinus venosus is a large quadrangular cavity which precedes the atrium on the venous side of the chordate heart.
The crista terminalis is a vertical ridge on the posterolateral inner surface of the adult right atrium extending between the superior vena cava, and the inferior vena cava. The crista terminalis denotes where the junction of the embryologic sinus venosus and the right atrium occurred during embryonic development. It forms a boundary between the rough trabecular portion and the smooth, sinus venosus-derived portion of the internal surface of the right atrium. The sinoatrial node is located within the crista terminalis.
Crista dividens is a structure in the developing heart of the human embryo that divides the right atrium in a way such that it creates a pan systolic murmur in the same way as the foramen ovale. Recognition of the absence of this murmur can indicate a potentially terminal cardiac defect in the newborn.
Rumex venosus is a species of flowering plant in the knotweed family known by the common names veiny dock, winged dock, sand dock, and wild-begonia. While not of any particular agricultural use, its cousins rhubarb and buckwheat are. It is native to central and western North America, from southern parts of the Canadian prairies, through to Mexico.
Dardanus venosus, the starry-eyed crab or stareye crab, is a species of hermit crab in the family Diogenidae. It occurs in shallow water on the eastern coasts of America from Florida southward to Brazil. It is sometimes kept in reef aquaria.
Heart development, also known as cardiogenesis, refers to the prenatal development of the heart. This begins with the formation of two endocardial tubes which merge to form the tubular heart, also called the primitive heart tube. The heart is the first functional organ in vertebrate embryos.
Adenanthos venosus is a species of flowering plant in the family Proteaceae and is endemic to a restricted part of the southwest of Western Australia. It is an openly-branched shrub with clustered egg-shaped leaves and reddish flowers.
Similosodus is a genus of longhorn beetles of the subfamily Lamiinae, containing the following species:
The veined catfish, also known as the marine catfish, is a species of sea catfish in the family Ariidae. It was described by Achille Valenciennes in 1840. It inhabits tropical marine and brackish waters in the Indo-western Pacific region, including the Mozambique Channel, Myanmar, Indonesia and southern China. It dwells at a depth range of 20 to 50 m. It reaches a maximum total length of 30 cm (12 in), but more commonly reaches a TL of 19 cm (7.5 in).
Similosodus transversefasciatus is a species of beetle in the family Cerambycidae. It was described by Stephan von Breuning in 1938, originally under the genus Sodus.
Similosodus chujoi is a species of beetle in the family Cerambycidae. It was described by Stephan von Breuning in 1982. It is known from Borneo.
Similosodus atrofasciatus is a species of beetle in the family Cerambycidae. It was described by Maurice Pic in 1934, originally under the genus Sodus.
Similosodus unifasciatus is a species of beetle in the family Cerambycidae. It was described by Maurice Pic in 1934, originally under the genus Sodus.
Similosodus ursulus is a species of beetle in the family Cerambycidae. It was described by Francis Polkinghorne Pascoe in 1866, originally under the genus Sodus. It is known from Malaysia.
Similosodus castaneus is a species of beetle in the family Cerambycidae. It was described by Per Olof Christopher Aurivillius in 1911, originally under the genus Sodus. It is known from Borneo and Malaysia.
