Document Summary
The nervous system of all mammals has two divisions: the central nervous system (cns) & the peripheral nervous. Chapter 7- the structure of the nervous system system (pns) Anterior (rostral)- front; posterior (caudal)- back; dorsal- pointing up; ventral- pointing down. Bilateral symmetry- the right side of the brain & spinal cord is the mirror image of the left side. Midline- the invisible line that runs down the middle of the nervous system. Medial- structures close to the midline; lateral- structures farther away from the midline: nose is medial to the eyes & eyes are medial to the ears etc. Ipsilateral- 2 structures on the same side; contraleteral- structures on the opposite sides of the midline. A slice is a section; to slice is to section. The horizontal plane is parallel to the ground- split the brain into dorsal & ventral parts; single section in this plane could pass through both the eyes and the ears.
