Dorsal toward back Ventral toward tummy ------------------------------------------- Dorsal on head is on top of head Chin is ventral on head Anterior is the front Posterior is the back towards the butt Rostral is towards the nose --- rhymes with nostril Caudal is towards the tail Medial is towards midline of the person Lateral is toward the side of the animal Distal is further away Proximal is closer ---- Tip of nose to eyes is - ventral, medial, and anterior <- all the above, also rostral --- Coronal plane – i.e. transverse plane (frontal section) - cut in crown direction sagittial plane - down the nose verticle - face in half perisaggital - beside the midline, only the sagittial plane has been cut horizontal plane - i.e. axial Neural tubes turn into three major divisions - rostral: towards the nose o telencephalon cerebral cortex basal ganglion most of the limbic system - caudally – towards tail o diencephalon thalamus hypothalamus - more caudal o mesencephalon tectum collicale tegmentum - more caudally o metencephalon cerebellum pons o myelencephalon medulla oblongata (i.e. medulla) - main q: what subdivision is an area in? olfactory system - confined to telencephalon - stria = stripe = white stripe bc myelinated iclicker – patient, lost of smell, reacts to noxious substances held under nose, has a runny nose, what is true - other sensory nerves innervating the face are intact - damage to the olfactory nerve - noxious chemical – pain – not the olfactory at all o so other sensory nerves are working - the skull is thin, gets cracked, and CSF is running down his nose ventral view of the brain - red is the olfactory bulb - gray is the projections of the olfactory tract - going to the pyriform (pear shaped) area sheep brain - ventral view iclicker question - olfactory doesn’t project to thalamus; goes straight to cortex; we would exp to find the olf proj to which subdivision? o telencephalon – the cerebral cortex, basal ganglia, and most of the limbic system anterior commissure – connect olfactory bulb on one side to the other side olf proj to septal nuclei and amygdala olf summary olf nerve synapses with olf bulb, contralateral to opposite olf bulb thru anterior commissure, visual system - how info in diff sec are segregated - left and right hemifields are segregated and stay that way - LGN go to the visual visual cortex called V1 or area 17 or striate cortex mm
