The Tela Choroidea (Rear View)

Description

Framed from a posterior perspective within the ventricular system, the animation focuses on the tela choroidea, a thin vascular pia-derived membrane spanning the roof of the third ventricle and contributing to the choroid plexus. As the view settles from posterior toward the midline, the tela is seen draped between the paired thalami, superior to the hypothalamus and contiguous with the velum interpositum housing the internal cerebral veins. Subtle sequential reveals clarify how the membrane relates superiorly to the fornix and inferiorly to the cavity of the third ventricle. Relationships are the point. That spatial logic matters when you are teaching cerebrospinal fluid production and circulation or explaining why intraventricular hemorrhage and inflammatory debris often track along the choroid plexus. Posterior views can be disorienting in static atlases, but motion that toggles depth and midline alignment helps learners distinguish tela choroidea from adjacent ependymal surfaces and from arachnoid membranes that never enter the ventricles. It also sets up common operative corridors, including transcallosal and transcortical approaches where the velum interpositum and internal cerebral veins become non-negotiable landmarks. Use this animation in neuroanatomy and neuroradiology teaching to anchor ventricular roof anatomy, in CSF physiology modules, or as a figure supplement for manuscripts discussing choroid plexus papilloma, ventriculitis, or endoscopic third ventriculostomy planning.
