Retinal anatomy [1] The retina is a many layered structure. From the inner (vitreous) surface to the choroid these are the internal limiting membrane, nerve fibre layer, ganglion cell layer, inner plexiform layer, inner nuclear layer, outer plexiform layer, outer nuclear layer, external limiting membrane, rod and cone inner and outer segments and a single layer of cells called the retinal pigme...

A laryngopyocele forms when a laryngocele becomes infected and fills with mucopus. We report a case of an internal larngopyocele that presented as airway obstruction in a 34-year-old man; such a presenting sign is exceedingly rare. We also review the anatomy, etiology, and clinical course of the different types of laryngoceles.

Infection of the internal umbilical remnants is a common problem in neonatal foals. Accurate diagnosis and monitoring response to medical therapy requires knowledge of the ultrasonographic technique, anatomy, and dimensions of normal structures.

During gross anatomy head and neck laboratory session, one dissection group observed an abnormal anatomic variation in the posterior cranial fossa of a 94-year-old male cadaver. The internal occipital crest was not aligned with internal occipital protuberance and groove for superior sagittal sinus. It seemed that the internal occipital protuberance was shifted significantly to the right side. A...

We report a case of progeria and the utility of visualizing the cerebrovascular anatomy by using MR angiography. A 4-year-old child with Hutchinson-Guilford syndrome developed symptoms of ischemia and MR angiography showed bilateral occlusion of internal carotid and vertebral artery origins; the anterior spinal artery was prominent.
