Coxal gland and its components. The coxal gland is a gland found in some arthropods, for collecting and excreting urine. They are found in all arachnids (with the exception of some Acari), and in other chelicerates, such as horseshoe crabs. [1] The coxal gland is thought to be homologous with the antennal gland of crustaceans.
Antennae (sg.: antenna) (sometimes referred to as "feelers") are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.
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.
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.

Dogs use their mouths an awful lot – their mouths help them make sense of the world around them. Most of the time, they’ll use their mouths for harmless purposes, but dogs can bite people and ...
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 ...
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 ...
Trematodiasis is a group of parasitic infections caused by different species of flukes, in humans mainly by digenean trematodes. [4] Symptoms can range from mild to severe depending on the species, number and location of trematodes in the infected organism. [1]
