2A) suggests that algal clusters arise from mitotic division of a single invading cell, with the algal symbionts moving either through the anemone's tissue or via transport in the gastrovascular
Hydroids more or less transparent, such that the mouth opening detected only during the feeding process and the gastrovascular
cavity observed by transparency.
In both species, very good results were observed by additionally administering small doses (1 to 2 mL) of 6% Mg[Cl.sub.2] directly into the gastrovascular
cavity of the animal, right before being immerse in the fixative.
A single hemolymph sample was extracted from the gastrovascular
cavity of each zoanthid by puncturing with a 50 [micro]L syringe.
Effect of gastric distension on cardiovascular parameters: Gastrovascular
reflex is attenuated in the elderly.
1 A) y son: a) con cuatro conductos radiales rectos y delgados; b) un manubrio cuadrangular y en forma de botella, labios acanalados, encorvados y prominentes que se extienden hasta la mitad de la distancia del apice interno de la cavidad umbrelar a la abertura velar; c) cuatro gonadas lineares que se extienden desde las esquinas radiales de la cavidad gastrovascular
hasta la mitad de la longitud de los conductos radiales.
To accomplish the bioassay, proliferating interstitial cells are labeled with BrdU by injecting BrdU into the gastrovascular
cavity of the animal (n = 10).
Early laboratory studies of allorecognition showed that when two allogeneic colonies (i.e., nonclone-mates) grew into contact, rather than simply not fusing (as in many colonial ascidians, bryozoans, and sponges), one of the colonies (and usually both) produced a set of specialized, nematocyst-laden, tubular extensions of the gastrovascular
system, termed hyperplastic stolons (Schijfsma 1939; Ivker 1972).
At this point, [alpha]-tubulin-like immunoreactions ([alpha]-tubulin LIR) also showed expansion of the cilia-covered gastrovascular
cavity in the stalk (Fig.
The epidermis containing the rhabdites can be seen, together with the gastrovascular
cavity and the lumen of pharynx.
1979, Wellington 1980, Chornesky 1983, Ates 1989), or through extracoelenteric digestion, using the mesenteric filaments of the gastrovascular
cavity (Lang 1970, 1973, Logan 1984, Sheppard 1979, Cope 1981, Yamazato and Yeemin 1986).
