The brainMeninges – connective tissue covering the brainDura mater – the substance covering the brain and spinal cord• Endosteal layer – resembles the periosteum of bones, supplies blood vessels• Meningeal layer – dense, fibrous membrane • Falx cerebellum – a large crescent-shaped fold located in the middle of the cerebral hemispheres • Tentorium cerebellum – large horizontal crescent-shaped fold attached to the inner surface of the occipital bone • Falx cerebellar – a fold which divides the cerebellar hemispheres and is attached internally to the occipital bone and is small and crescent-shaped• Subdural space – an area between the dura mater and the arachnoid filled with fluidArachnoid – a protective membrane covering the brain• Subarachnoid space – area between the pia mater and the arachnoid bone • Cerebrospinal fluid – clear fluid found in the brain and spinal cord Pia mater – fragile innermost layer of the meninges Telencephalon – the brain arises from here • Cerebral hemispheres – the divided regions of the brain Diencephalon – sensory information; has the next three parts• Thalamus – sensory information to the cortex • Hypothalamus – main system of the endocrine system and releases or inhibits hormones responsible for the pituitary gland • Third ventricle – a hollow space filled with cerebrospinal fluid; produces cerebrospinal fluid Midbrain – deals with vision, hearing and motor functions • Cerebral peduncles – form the anterior part of the midbrain • Corpora quadrigemina - two groups of colliculi with white matter on the outside and gray matter on the inside • Aqueduct Mesencephalic – contains CSF and articulation of the third and fourth ventricles Metencephalon – is composed of the three...... half of the paper ......, for hearing and balance• Glossopharyngeal (IX) – posterior cranial fossa and neck, jugular foramen, allows for taste from the posterior third region of the tongue and general sensations such as general sensations from the middle ear • Vagus (X) – jugular foramen; motor functions and general functions; controls the muscles of the hard palate; provides sensation of the thoracic and abdominal viscera • Accessory (XI) – jugular foramen and foramen magnum; motor functions, distributes the muscles of the hard palate and connects to the spinal cord • Hypoglossal (XII) – neck, oral cavity, posterior cranial fossa, hypoglossal canal, supplies nerves to most tongue muscles and motor skillsSources: APR McGraw-Hill Connect http://www.merriam-webster.com/medlineplus/medial+geniculate+body http://en.wikipedia.org/wiki/Sensory_cortexhttp://www.indiana.edu/~p1013447/dictionary/assn_cor.htm
