After having been taken out of water for a short time, and then again immersed in it, a considerable quantity both of water and air is absorbed by the mouth, and perhaps likewise by the branchial orifices.
The fish, having remained in this distended state for a short time, generally expelled the air and water with considerable force from the branchial apertures and mouth.
We cannot, for instance, suppose that in the embryos of the vertebrata the peculiar loop-like course of the arteries near the branchial
slits are related to similar conditions,--in the young mammal which is nourished in the womb of its mother, in the egg of the bird which is hatched in a nest, and in the spawn of a frog under water.
plates narrow euribasal (length:width ratio 1.
When the octolasmids inhabit branchial
chambers of the crabs, they occupy space on the gills surface normally available for gaseous exchange and can severely impair host respiration (Hudson and Lester, 1994).
A defective model of the chick thymus was created by administering RA, which disrupted the signalling molecular cascade involving endothelin-1, essential for normal development of branchial
Pathological diagnosis was obtained: schwannomas (8 cases), salivary pleomorphic adenomas (5 cases), angiomas (5 cases), branchial
cysts (3 cases), Castleman disease (2 cases), and 1 case for each of the followings: lymphoepithelial cysts, thyroid cancer lymphatic metastasis, phosphate urinary mesenchymal tissue tumor, basal cell adenoma, myoepithelial carcinoma, fibroma, adenoid cystic carcinoma, and lipoma.
Miyake & McEachran (1991) worked with the branchial
arches skeleton of batoids, including some Urotrygonids species.
Based on these findings, a diagnosis of bilateral second branchial
cleft fistulae was made.
It was found that if the snail shell was cracked and the snail's branchial
gland removed, its juice when extracted and put in a clear bowl and placed in the sunlight caused something stunning to happen: The juice, which was white, turned greeny-yellow, then a definite green, then violet before finally turning red and darkening as the minutes ticked by.
Some of the primary PPS masses include minor salivary gland tumors arising from ectopic salivary gland tissue rests, atypical type II first branchial
cleft anomaly, and lipomas.
Differential diagnosis of Thornwaldt's cyst is branchial
cleft cyst, Rathke's pouch cyst, adenoid retention cyst, meningocoele, sphenoid sinus mucocoele, JNA and possibly nasopharyngeal carcinoma.
