Document Summary
The human brain appears complicated because it is distorted as a result of the selective growth of some parts within the confines of the skull. The nervous system of all mammals has 2 divisions: the central nervous system (cns, the peripheral nervous system (pns) Medial structures close to the midline. Lateral structures farther away from the midline: ipsilateral - 2 structures that are on the same side, contralateral 2 structures that are on the opposite sides of the midline. To view the internal structure of the brain, it is usually necessary to slice it up: section a slice (to slice is to section) The standard approach to is to make cuts parallel to one of the 3 anatomical planes of section: midsagittal plane the plane of the section resulting from splitting the brain into equal right and left halves. Sagittal plane sections parallel to the midsagittal plane: horizontal plane perpendicular to the sagittal plane and is parallel to the ground.
