Document Summary
Week 2 structure of the nervous system. 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. Understanding cns structure through development: let"s highlight some of the special features of the human central nervous system by comparing with the rat brain. Convolutions, the gyri and sulci: lissencephalic rats, gyrencelphalic humans. Size of the olfactory bulb: humans have a relatively small olfactory bulb, rats have a relatively larger olfactory bulb (think, why?) Growth of the cerebral hemispheres: humans have different lobes (temporal, parietal, occipital, frontal, rats do not have these organizations. Gross organization: anatomical references (know these) The brain does not have the same positional references as the spinal cord for bipeds. Bilateral symmetry when a structure is identical on both the right and left side of the brain. Sagittal the cut resulting from splitting the brain into equal right and left halves.
