Lab 17, Station 3: Gross Topography of the Brain
Lab 17 navigation Station 3: Gross Topography of Brain Cerebrum Composed of left and right hemispheres. The hemispheres are connected across the midline by a thick tract of nerve fibers called the corpus callosum. Each hemisphere contains a cavity called a lateral ventricle—filled with cerebrospinal fluid.
Lab 17, Station 2: Cranial Base and Cranial Nerves
Lab 17 navigation Station 2: Cranial Base and Cranial Nerves The cranial cavity is the space within the neurocranium. It contains the brain, meninges, blood vessels, and the proximal parts of the cranial nerves. The floor is the cranial base. Foramina in the cranial base transmit cranial nerves and blood vessels. The cranial base has […]
Lab 17, Station 1: The Skull
Lab 17 navigation Station 1: The Skull The skull is divided into two parts: Neurocranium and Viscerocranium. Neurocranium (“brain case”) = Frontal bone, ethmoid, sphenoid, occipital bone, temporal bones (2), and parietal bones (2) The neurocranium has a roof called the calvaria (“skull cap”). Fibrous joints called sutures join the bones. The largest sutures are […]

Templates for drawing the pathways of the cranial nerves Cranial nerves templates Previous The mixed cranial nerves
The mixed cranial nerves
Cranial nerve V: Trigeminal nerve Functions Innervates skin of the face, mucous membranes in oral and nasal cavities, external ear, and teeth (general sensory). Innervates muscles of mastication and other muscles in the neck, palate, and middle ear (skeletal motor). Skull opening Ophthalmic branch (V1) = Superior orbital fissure Maxillary branch (V2) = Foramen rotundum […]
The mainly motor cranial nerves
Cranial nerve III: Oculomotor nerve Functions Innervates four of the six extrinsic muscles that move the eye + the muscle that elevates the upper eyelid (skeletal motor). Innervates smooth muscle in the eyeball (parasympathetic). Skull opening Superior orbital fissure. Attachment to brainstem Midbrain. Nucleus of origin/destination in CNS Skeletal motor fibers originate from the oculomotor […]
The sensory cranial nerves
Cranial nerve I: Olfactory nerve Functions Olfaction (smell)—special sensory. Skull opening Olfactory (cribriform) foramina. Nucleus of origin/destination in CNS Bipolar neurons of olfactory nerves synapse on secondary olfactory neurons in olfactory bulbs. Details The ceilings of the nasal cavities are lined by a special olfactory epithelium that includes the peripheral processes of primary olfactory neurons […]
