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.
Opioid peptides and opioid receptors occur naturally in crustaceans, and although it was concluded in 2005 "at present no certain conclusion can be drawn", [3] more recent considerations suggest their presence along with related physiological and behavioural responses as indicating that crustaceans may experience pain.
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.

Frey's syndrome (also known as Baillarger's syndrome, Dupuy's syndrome, auriculotemporal syndrome, [1] or Frey-Baillarger syndrome) is a rare neurological disorder resulting from damage to or near the parotid glands responsible for making saliva, and from damage to the auriculotemporal nerve often from surgery.
It is most frequently discovered as a soft mass or swelling in the neck of infants and children. [2] However, when symptoms do occur they are most commonly due to compression of nearby structures such as the trachea and esophagus. This can lead to hoarse voice, stridor, difficulty breathing and/or difficulty swallowing. [3] [4] Pain is uncommon ...

Hidradenitis suppurativa is a chronic cutaneous condition originally thought to be primarily characterized by suppurative inflammation of the apocrine sweat glands. [ 3 ] : 710 Recent evidence supports that the primary event is follicular hyperkeratosis and obstruction, [ 4 ] but the term hidradenitis supperativa has continued to be used in ...
