Document Summary
Anatomical planes of sections: coronal (frontal) section: section that divides the brain front to back. Allows a front view of the brain: sagittal section: section that is paralleled to the midline. Allows a side (medial) view of the brain. Midsagittal section: a sagittal section that divides the brain into two approximately equal halves: horizontal (axial) section: section that divides the brain from top to bottom. Allows a birds-eye view of the brain. Meninges: the layers of the membranes that cover the central nervous system and the peripheral nerves: dura mater: the outermost layer of the three meninges, found in both the central and peripheral nervous systems. Composed of leather-like tissue that follows the outlines of the skull bones: arachnoid mater: the middle layer of the meninges covering the central nervous system. A more delicate structure with spider web-like cross-sections. Sticks closely to the outside of the brain: meningitis: infection of the meninges.
