  2. Coxal gland - Wikipedia

    en.wikipedia.org/wiki/Coxal_gland

    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 ...

  3. Antenna (zoology) - Wikipedia

    en.wikipedia.org/wiki/Antenna_(zoology)

    The three basic segments of the typical insect antenna are the scape or scapus (base), the pedicel or pedicellus (stem), and finally the flagellum, which often comprises many units known as flagellomeres. [10] The pedicel (the second segment) contains the Johnston's organ which is a collection of sensory cells. [11]

  4. Ionocyte - Wikipedia

    en.wikipedia.org/wiki/Ionocyte

    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]

  5. Nephridium - Wikipedia

    en.wikipedia.org/wiki/Nephridium

    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.

  7. Malpighian tubule system - Wikipedia

    en.wikipedia.org/wiki/Malpighian_tubule_system

    Malpighian tubules are slender tubes normally found in the posterior regions of arthropod alimentary canals. Each tubule consists of a single layer of cells that is closed off at the distal end with the proximal end joining the alimentary canal at the junction between the midgut and hindgut. Most tubules are normally highly convoluted.

  8. Arthropod head problem - Wikipedia

    en.wikipedia.org/wiki/Arthropod_head_problem

    A typical insect head possesses a pair of antennae; eyes; mandibles, labrum, maxillae and labium (the latter four forming the cluster of "mouth parts", no. 32. in the diagram). Lying above the oesophagus is the brain or supraesophageal ganglion , divided into three pairs of ganglia: the protocerebrum, deutocerebrum and tritocerebrum from front ...

  9. Insect morphology - Wikipedia

    en.wikipedia.org/wiki/Insect_morphology

    The salivary glands (element 30 in numbered diagram) in an insect's mouth produce saliva. The salivary ducts lead from the glands to the reservoirs and then forward through the head to an opening called the salivarium, located behind the hypopharynx. By moving its mouthparts (element 32 in numbered diagram) the insect can mix its food with saliva.
