The skeleton of the green Iguana iguana (Squamata: Iguanidae) and its intraspecific morphological variation

The Anatomical Record, EarlyView.
Abstract The green iguana (Iguana iguana) is an iguanine lizard with herbivorous and arboreal habits, whose distribution spans through South America, Central America to the south of North America. Although the genus Iguana is well‐known, the species still lacks a comprehensive and up‐to‐date anatomical study, particularly addressing the axial skeleton,

Analysis of potential risk factors for the occurrence of brainstem symptoms in subjects with giant intracranial aneurysms of the posterior circulation [PDF]

, 2019
Object. Giant intracranial aneurysms of the posterior circulation (GPCirA) often cause compression of the brainstem and adjacent structures, resulting in neurological deficits. Using data from the Giant Intracranial Aneurysm (GIA) Registry, we designed a
