The coxal gland is thought to be homologous with the antennal gland of crustaceans. The gland consists of an end sac (saccule), a long duct (labyrinth) and a terminal bladder (reservoir). [2] There is generally only one pair (two in some spiders), and they open on the coxae of the walking legs [1] or at the base of the second antennae in the ...
In Crustacea, the saccate metanephridia are associated with the antennae and form the antennal gland. In freshwater crustacea, the saccate metanephridia are especially large due to their role in osmoregulation; crustacea must remove large amounts of water from the tissues, as the cells are hypertonic to the surrounding water.
An ionocyte (formerly called a chloride cell) is a mitochondrion-rich cell within ionoregulatory organs of animals, such as teleost fish gill, insect Malpighian tubules, crustacean gills, antennal glands and maxillary glands, and copepod Crusalis organs. [1]
Human bites are the third most frequent type of bite after dog and cat bites. [6] Dog bites are commonplace, with children the most commonly bitten and the face and scalp the most common target. [14] About 4.7 million dog bites are reported annually in the United States. [15] The US estimated annual count of animal bites is 250,000 human bites ...
A dog in West Virginia is thriving after a suspected snake bite which left him with an extremely swollen head.. The story of the dog's plight recently went viral following a Reddit mention, but ...
Histological changes are seen in the gill epithelium, antennal gland, haematopoeitic tissue, nervous tissue, connective tissue, and intestinal epithelial tissue. Infected cells have prominent intranuclear occlusions that initially stain eosinophilic , but become basophilic with age; hypertrophied nuclei with chromatin margination; and ...
The tarsus of insects corresponds to the penultimate segment of a generalized arthropod limb, which is the segment called the propodite in Crustacea. In adult insects, it is commonly subdivided into two to five subsegments, or tarsomeres, but in the Protura, some Collembola, and most holometabolous insect larvae it preserves the primitive form ...
A dog bite is a bite upon a person or other animal by a dog. More than one successive bite is often called a dog attack , although dog attacks can include knock-downs and scratches. Though some dog bites do not result in injury , they can result in infection , disfigurement , temporary or permanent disability , or death .
