A.
perivascular space
A perivascular space is a fluid-filled, microscopic channel that surrounds blood vessels as they pass through the brain or other tissues, facilitating fluid exchange and waste clearance.
-
B.
median aperture of the fourth ventricle
The median aperture of the fourth ventricle is a midline opening in the roof of the fourth ventricle that allows cerebrospinal fluid to flow from the ventricular system into the subarachnoid space, particularly the cisterna magna.
-
C.
cortical area
A cortical area is a distinct region of the cerebral cortex characterized by specific cytoarchitecture, connectivity, and functional roles in processing sensory, motor, or cognitive information.
-
D.
arboreal tract
An arboreal tract is a continuous area of tree-dominated vegetation that provides habitat, connectivity, and ecological functions within a forested or wooded landscape.
-
E.
paired artery
chosen
