Document Summary
Pyramidal @ medulla-spinal cords level / ventral tegmental @ midbrain. Movement of contralateral legs (flexion), fine motor movements. Movement of contralateral arms (flexion), fine motor movements. Cranial nerves bilaterally, except vii - below the eyes it"s contralateral. Automatic posture and gait - medullary part has influence from cortex and has inhibitory function on muscle tone; pontine - extention both, medullary - flexion both. Discriminative aspects: type, location; temperature, sharp, pricking, localizable pain. P to heart, lungs and digestive tract, taste, swallowing, voice box. Axons from the lateral geniculate nucleus (thalamus) that terminate in the primary visual cortex; receives blood supply from mca + pca; has divisions along the calcarine fissure. Lower division, fibers from inferior retina; loops around inferior horn of lateral ventricle; info from superior visual field. Upper division; from superior retina; pass parietal to occipital lobe; info from inferior visual field. Pie in the sky or pie on the floor.
