Document Summary
Chapter 2: functional neuroanatomy and the evolution of the nervous system. Anatomical directions and planes of section. Inferior toward the bottom. Rostral located towards the head end of the animal. Caudal towards the tail end of the animal. Ventral towards the belly side. Superior toward the top. Midline an imaginary line that divies us into approx. equal halves. Ipsilateral two structures are on the same side of the midline ; ex: left arm and left leg. Contralateral - structures are on opposite sides f the midline; ex: right arm and left leg. Medial close to the midline. Proximal close to the center. Distal far away from the center; proximal and distal usually used to refer to limbs. Bc humans are two- legged, our neuraxis (an imaginary line that runs the length of the. Lateral to the sides of the midline spinal cord through the brain) is different from a 4- legged animal.
