Document Summary
Frontal lobe: largest of the lobes, 1/3 of the cortex, predominates in, planning. Inhibition of voluntary motions: cognitive function, bounded posteriorly by central sulcus. Inferiorly by lateral sulcus: medial: longitudinal fissure, three gyri, superior frontal gyrus, borders the longitudinal fissure, middle frontal gyrus. Therefore, a unilateral upper motor neuron lesion could cause a unilateral facial droop or problems with tongue protrusion on the opposite side of the body: face, head, laryngeal regions, medial edge, leg, thigh, thorax. Parietal lobe: primary reception sire for somatic (body) sense, all sense that reach consciousness terminate within the parietal lobe, anterior boundary, central sulcus. Insula: also known as the insular cortex or the island of reil, located, deep to a region of the cerebrum, known as: operculum. Limbic system: not an anatomically distinct region, associated with, motivation, sex drive, emotional behavior, affect. Includes uncus, parahippocampal gyrus, cingulate gyrus, olfactory blub, hippocampal formation, orbitofrontal cortex and dentate gyrus: dentate, tooth, notched, tooth like.
