Distribution and Comparative Morphology of the Cloacal Gland in Ants (hymenoptera: Formicidae)
The cloacal gland is a paired exocrine structure, which has so far been described only in the formicine species, Camponotus ephippium and Cataglyphis savignyi (Hymenoptera : Formicidae). The gland is formed by 2 clusters of bicellular units with slender duct cells, releasing the glandular secretion through the cloacal membrane. In the present work, a number of ant species, largely of the Formic...
متن کاملFunctional Specialization of the Extrinsic Venom Gland Musculature within the Crotaline Snakes (Reptilia: Serpentes) and the Role of the M. Pterygoideus Glandulae
-The extrinsic venom gland musculature in snakes exhibits a reasonably conserved spatial pattern around the venom gland. A prominent exception to this pattern is the M. Pterygoideus Glandulae, which originates from the surface of lhe venom gland itself. This muscle is found only in crotaline snakes, and has a spotty distribution within that group. Previous workers proposed that the M. Pterygoid...
متن کاملFunctional morphology of the palato-maxillary apparatus in "Palatine dragging" snakes (Serpentes: Elapidae: Acanthophis, Oxyuranus).
Elapid snakes have previously been divided into two groups (palatine erectors and palatine draggers) based on the morphology and inferred movements of their palatine bone during prey transport (swallowing). We investigated the morphology and the functioning of the feeding apparatus of several palatine draggers (Acanthophis antarcticus, Oxyuranus scutellatus, Pseudechis australis) and compared t...
