The hypopallial region is also known as the dorsal ventricular ridge, described as having anterior and posterior (amygdaloid) regions. [ 4 ] Birds essentially show much increased cellularity, keeping within the reptilian morphological schema, which leads to the apparent disappearance of layering within its medial and dorsal pallial sectors.
The vascular organ of lamina terminalis (VOLT), organum vasculosum of the lamina terminalis (OVLT), or supraoptic crest [1] is a sensory organ, one of the circumventricular organs of the third ventricle within the lamina terminalis. It is covered with pia mater, and lined with ependyma.
The tegmentum is the ventral part of the midbrain and the tectum is the dorsal part of the midbrain. [1] It is located between the ventricular system and distinctive basal or ventral structures at each level. It forms the floor of the midbrain (mesencephalon) whereas the tectum forms the ceiling. [2]
The ventricular system is continuous with the central canal of the spinal cord from the fourth ventricle, [3] allowing for the flow of CSF to circulate. [ 3 ] [ 4 ] All of the ventricular system and the central canal of the spinal cord are lined with ependyma , a specialised form of epithelium connected by tight junctions that make up the blood ...

The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, at the superior portion of the right ventricle.The function of the valve is to allow blood to flow from the right atrium to the right ventricle during diastole, and to close to prevent backflow (regurgitation) from the right ventricle into the right atrium during right ventricular ...
Other structures near to it are the membranous septum and the Eustachian ridge. Variations in the size of Koch's triangle are common. Variations in the size of Koch's triangle are common. The triangle of Koch is an important landmark for atrioventricular catheter ablation procedures for the localization of the atrioventricular node.
In the developing cerebral cortex, which resides in the dorsal telencephalon, the SVZ and VZ are transient tissues that do not exist in the adult. [4] However, the SVZ of the ventral telencephalon persists throughout life. The adult SVZ is composed of four distinct layers [5] of variable thickness and cell density as well as cellular composition.
