NROB60H3 Chapter Notes - Chapter 7: Central Nervous System, Sagittal Plane, Median Plane
Document Summary
The structure of the nervous system (lecture 2) Two divisions to all mammal nervous systems: central nervous system (cns) and peripheral nervous system (pns) Bilateral symmetry: characteristic of the right side of the brain and spinal cord is a mirror image of the left side. Midline: invisible line running down the middle of the nervous system. Ipsilateral: two structures that are on the same side of the midline (right ear is ipsilateral to the right eye) Contralateral: structures that are opposite sides of midline. Section: a slice of the brain; to slice: to section: anatomist lingo ^ Standard approach to section is to make cuts along one of the three anatomical planes of section. Mid-sagittal plane: plane of the section resulting from splitting the brain into equal right and left halves. Sagittal plane: sections parallel to the mid-sagittal plane. Coronal plane: perpendicular to the ground and to the sagittal plane.
