Document Summary
Crosses at the level of entry in the spinal cord immediately crosses to contralateral side and runs parallel to the spinal cord. How does the dorsal column medial lemniscal pathway run, where does it cross, where does it go in the thalamus? touch and proprioceptive info. What in general do the parts of the the vestibular system respond to? two otolith/otoconia organs (succle and utricle) linear motion. Mapping of body surfaces on the brain. Posterior parietal lobe: be able to locate on sketches of the parietal lobe: anterior parietal area, general location of superior parietal lobule, and inferior parietal lobe. Precentral gyrus: primary motor area, motor strip. Post central gyrus: the main sensory receptive area for sense of touch; mao of sensory space. Guidance of movement (with constant feedback as you execute motions) Spatial navigation (near space: what are the other functions of the posterior parietal lobe (listed as "vaguely spatial")
