We sexed each snake by probing its cloaca to detect the presence of hemipenes. |
|
Instead, males deposit spermatophores on the substrate and females pick up these spermatophores with their cloaca later. |
|
Unlike we humans, the chicken has a single sexual and excretory orifice, the cloaca. |
|
After males deposit spermatophores onto the cloaca of females, up to 150 eggs are laid on mud near water. |
|
Salamanders were measured from the tip of the snout to the anterior end of the cloaca. |
|
The cloaca maxima was the sewer system built in the sixth or seventh century BC, by one of the kings of Rome. |
|
The urachus is a remnant of allantoic origin, connecting the embryonal cloaca to the allantois during early intrauterine life. |
|
This structure is actually a highly vascularized extension of the cloaca which allows internal fertilization. |
|
The remains of the central baths are only visible today as a slight elevation in the area of the present-day steps leading down to the cloaca. |
|
In young birds, open the bursa of Fabricius through its opening to the cloaca. |
|
The bursa of Fabricius is an organ located just beside the cloaca. |
|
This can be carried out manually, or with a vent gun, which sucks out the contents of the bird's cloaca and causes it to collapse. |
|
Evisceration is carried out in the following phases: hanging on the preparation belt, cutting the skin of neck, cutting of the cloaca, abdominal opening, extraction of the viscera and cutting of the neck. |
|
Because humor, no longer a stranger to paradox, decorating despair with the honors of a good education, relegates hope in the already heavily populated cloaca of nauseating insults. |
|
It is built similarly to the wastewater cloaca at the central baths. |
|
In a cloaca smear, we can see the presence of Hexamitiasis. |
|
Similarly, it is not possible for the increased volume of urine that collects in the cloaca following excessive water intake to be adequately thickened. |
|
A modern connecting tunnel leads today from this basement to the cloaca. |
|
The extremely well preserved basement was linked by a short underground corridor with the cloaca, the wastewater channel nearby and was accessed by the same steps. |
|
Free the intestine by cutting the colon just before it enters the cloaca. |
|
|
The male distinguishes itself from the female by its generally brighter colouring, the more conspicuous lines on the sides of the head, the crest along the spine and the distended cloaca during the breeding season. |
|
Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. |
|
The hemipenes are often grooved, hooked, or spined in order to grip the walls of the female's cloaca. |
|
This material, as well as the output of the intestines, emerges from the cloaca. |
|
Its collecting duct opens into the hindmost part of the intestine, called the cloaca, and later also serves as the collecting duct of the mesonephros. |
|
The descendants of the SA51 breeding hen are sexed using the cloaca, while the SA51A birds can be sexed via the wing feathers, which can offer advantages when rearing the two sexes separately. |
|
You also will soon learn to point the cloaca away from you. |
|
The ureters leave the ventral caudomedial surface and continue caudally, near the midline into the opening of the urodeum of the cloaca. |
|
In early fetal development, the ventral cloaca is connected to the allantois via the urachus. |
|
A cotton swab was inserted into its cloaca and no obstruction or papillomatous lesions were detected. |
|
Some species of turtle have sacs called bursae on either side of the cloaca, with thin membranes that allow for gas exchange. |
|
On closer inspection, the male's cloaca is very distended, whilst the female's is nearly invisible. |
|
These projections, called papillae, have a rich blood supply and increase the surface area of the cloaca. |
|
However, the tenrecs, golden moles, and some shrews retain a cloaca as adults. |
|
As with all tetrapods, lizards rely on internal fertilisation and copulation involves the male inserting one of his hemipenes into the female's cloaca. |
|
The coprodeum and cloaca are the main osmoregulatory mechanisms used for the regulation and reabsorption of ions and water, or net water conservation. |
|
The male inserts one clasper into the female cloaca during copulation. |
|
A probe is inserted into the cloaca until it can go no further. |
