Cloaca

In animal anatomy, a cloaca (plural cloacae ) is the posterior orifice that serves as the only opening for the digestive, reproductive, and urinary tracts (if present) of certain animals, opening at the vent. All amphibians, birds, reptiles, and a few mammals ( monotremes, tenrecs, golden moles, and marsupial moles) have this orifice, from which they excrete both urine and feces; this is in contrast to most placental mammals, which have two or three separate orifices for evacuation. Excretory systems with analogous purpose in certain invertebrates are also sometimes referred to as cloacae.

The cloacal region is also often associated with a secretory organ, the cloacal gland, which has been implicated in the scent-marking behavior of some reptiles, amphibians, and monotremes.

Cloaca (film)

Cloaca is a 2003 Dutch film, directed by Willem van de Sande Bakhuyzen. It is a film adaptation of the 2002 theatre play Cloaca written by Maria Goos, who wrote the scenario for the film as well. The leading roles celebrate men in their 40s who were formerly student friends but since then have let their relationship go stale. They are played by: Goos's husband Peter Blok (Tom), Pierre Bokma (Pieter), Gijs Scholten van Aschat (Joep), and Jaap Spijkers (Maarten). Female roles were played by Caro Lenssen (Laura), Elsie de Brauw (Conny), and Marleen Stolz (Russian prostitute). Eric Schneider acted in a supporting role as Brest, Pieter's boss's boss.

Blok, Bokma, Goos, Scholten van Aschat, and Van de Sande Bakhuyzen know each other from the Toneelacademie Maastricht.

The film was conceived as a made-for-TV film (it was co-financed by the AVRO) but later got a cinema release. It won the public prize for Dutch film at a festival in 2003, and was released on DVD in 2005.

Cloaca (embryology)

The cloaca is a structure in the development of the urinary and reproductive organs.

The hind-gut is at first prolonged backward into the body-stalk as the tube of the allantois; but, with the growth and flexure of the tail-end of the embryo, the body-stalk, with its contained allantoic tube, is carried forward to the ventral aspect of the body, and consequently a bend is formed at the junction of the hind-gut and allantois.

This bend becomes dilated into a pouch, which constitutes the endodermal cloaca; into its dorsal part the hind-gut opens, and from its ventral part the allantois passes forward.

At a later stage the Wolffian duct and Müllerian duct open into its ventral portion.

The cloaca is, for a time, shut off from the anterior by a membrane, the cloacal membrane, formed by the apposition of the ectoderm and endoderm, and reaching, at first, as far forward as the future umbilicus.

Behind the umbilicus, however, the mesoderm subsequently extends to form the lower part of the abdominal wall and pubic symphysis.

By the growth of the surrounding tissues the cloacal membrane comes to lie at the bottom of a depression, which is lined by ectoderm and named the ectodermal cloaca.

Cloaca (Capri)

The Cloaca is an archaeological site on the island of Capri, Italy. It was part of a sewage system built in Roman times. The end of the sewer is visible west of the Marina Grande. It seems to have drained a considerable part of the northern side of the island, as evidenced by many smaller drains which are believed to have led into it. The fall of the sewer has been greatly changed. Instead of having a gentle gradient from south to north, it dips steeply in the reverse direction, north to south, at an angle of 25°. This reversal of incline has occasionally been cited as evidence for the alteration of the land-level of Capri since the Roman period.
