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.
Skara has a head with five segments which each contain an appendage pair; two pairs of antennae, a pair of mandibules and two pairs of maxillae. S. anulata's head shield resembles an inverted “U” in cross-section, and has been likened to an upside-down dinghy in shape, with a margin at its edge and slightly bulging rims. [1]
Since there is not a universally accepted classification for neck pain, it is difficult to study the different neck pain types. While neck pain is the second most common cause of disability and cost $100 billion [2], the NIH budgets only $10 million to the study of neck pain [3]. One of the most common neck pains is between the neck and the ...
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.
The researchers found that better diet quality, which meant having more vegetables, fruits, grains, lean proteins, and dairy, was linked to less chronic pain in the study participants. The results ...
The antennal lobe is the primary (first order) olfactory brain area in insects. The antennal lobe is a sphere-shaped deutocerebral neuropil in the brain that receives input from the olfactory sensory neurons in the antennae and mouthparts. Functionally, it shares some similarities with the olfactory bulb in vertebrates. [1]
