outline of brain organization forebrain telencephalon cerebrum layered cortex, deep nuclei and association tracts; sensation, voluntary motor, olfaction, vision, hearing, emotions, memory, language, associations cortical areas: prefrontal frontal Broca's area - efferent precentral central sulcus postcentral parietal Wernicke's area - afferent lateral sulcus temporal Wernicke's area - afferent occipital vision basal ganglia routine repetitive motor tasks caudate nucleus, lenticular nuclei (= corpus striatum) limbic system emotions, memory, language, associations amygdala, hippocampus, fornix, etc. midbrain diencephalon thalamus relay and processing between spinal cord and cerebrum hypothalamus vegetative functions hypophysis (pituitary) endocrine mesencephalon tectum visual and auditory spatial reflexes superior and inferior colliculi (corpora quadrigemina) tegmentum oculomotor complex, cerebral peduncles and deep nuclei (relay cerebrum cerebellum) hindbrain metencephalon cerebellum layered cortex and deep nuclei, motor coordination (tuning by inhibition) pons cerebellar decussation and pontine reticular formation myelencephalon medulla oblongata similar to spinal cord, cranial nerve nuclei, tracts and decussations, vegetative functions (sleep/wakefulness, vomite center, vestibular and cochlear nuclei, vagal nuclei) ventricles: lateral paired, in forebrain, curve along with caudate nucleus and fornix around lenticular nuclei, internal capsule and thalamus foramen of Monroe third ventricle midline, between right and left diencephalon cerebral aqueduct fourth ventricle midline, between cerebellum and brainstem spinal tracts to know: dorsal columns fasciculus gracilis fasciculus cuneatus spinocerebellar tracts (dorsal and ventral) spinothalamic tracts (ventral and lateral) corticospinal tracts (ventral and lateral) where are these located in cross sections of the spinal cord? are these afferent or efferent tracts? what information do they convey? are their projections contralateral or ipsilateral? also be familiar with: rubrospinal tract tectospinal tract olivospinal tract vestibulospinal tract are these afferent or efferent tracts? what information do they convey? peripheral nerves to know by location and function: brachial plexus (C5-T1) musculocutaneous n. median n. ulnar n. radial n. axillary n. lumbosacral plexus (L2-S3) femoral n. (L2-L4) obturator n. (L2-L4) sciatic n. (L4-S3) tibial n. common peroneal n.
