Foramen magnum: spinal cord

Foramen rotundum: mandibular division of trigeminal nerve

Foramen ovale: mandibular division of trigeminal nerve

Jugular foramen: Cranial nerve IX, X, XI

Foramen spinosum: middle meningeal artery

Corona radiata is made up of projection fibres

Internal capsule contains corticonuclear fibres in its posterior limb

Corpus callosum is made up of association fibres

Posterior limb of internal capsule lies between thalamus and lentiform nucleus

Commissures fibres: connects corresponding gyri of two cerebral hemispheres

Granular layer: granular cells and golgi cells

Molecular layer: stellate cells and basket cells

Globose nucleus is the largest cerebellar nuclei

Archicerebellum functions to maintain equlibrium

Midline lesion of cerebellum: truncal ataxia

Lateral ventricles and third ventricle are connected by interventricular foramen

Fourth ventricle: located dorsal to the pons and ventral to the cerebellum

Pia mater is the innermost meningeal layer

Dural folds include falx cerebri, falx cerebelli, tentorium cerebelli and diaphragma sellae

Floor of the fourth ventricle: inferior fovea that divide medial eminence into 3 triangles

Pons: transverse pontine fibers originate from pontine nucleus

Midbrain: Decussation of superior cerebellar peduncles is located at level of inferior colliculus

Midbrain: Oculomotor nucleus is located at level of inferior colliculus

Medulla oblongata: supplied by anterior and posterior spinal artery, vertebral artery

Brainstem is located at posterior cranial fossa of the skull

Corpus striatum consist of caudate nucleus and lentiform nucleus

Claustrum: Its lateral relations are extreme capsule and insular cortex

Amygdaloid body is located in the occipital lobe

Substantia nigra is situated between tegmentum and crus cerebri of midbrain

Lentiform nucleus: globus pallidus + putamen

Anterior cerebral artery is part of Circle of Willis

Vertebral artery converge to form basilar artery

Posterior inferior cerebellar artery arise from basilar artery

Superior cerebral vein drains into superior sagittal sinus

Thalamostriate and choroidal vein unites to form the internal cerebral vein

Lower end of the spinal cord is called conus medullaris

Dorsal root carries sensory nerve fibers

Dorsolateral tract of Lissaeur is part of the grey matter

Lumbar puncture is usually performed at the lumbar cistern

Filum terminale descends and attach to the dorsal surface of the coccygeal bone

Ascending tracts include the vestibulospinal tract

Spinothalamic tracts: cell bodies of 2nd order neurons are located in substantia gelatinosa

Dorsal column tracts lesion: Loss of sensation on the same side below the lesion

Spinocerebellar tracts: cell bodies of 2nd order neurons are located in Clarke's column

Conscious sensation is made up of a series of three neurons

Pyramidal tracts: all pyramidal fibers will ultimately cross to the opposite side

Corticonuclear tracts: Ends in the motor nuclear of cranial nerves in the brainstem

Corticospinal tracts: In midbrain, fibers of 1st order neurons descend through lateral 3/5th of the cerebral peduncles

Corticospinal and corticonuclear tracts influence the motor neurons for voluntary, rapid skilled movements

Extrapyramidal tract in the lateral white column is rubrospinal tract

Lesion to CN I: cause anosmia

CN II: Fibers from temporal hemiretina pass to the same side

Vestibular nerve receptor: Organ of Corti

Disturbance of cochlear nerve: cause deafness and tinnitus

Trochlear nerve supplies the superior oblique muscle

Oculomotor nerve supplies the lateral rectus muscle

Abducent nerve exits skull through superior orbital fissure (inside tendinous ring)

Accessory nerve: spinal root innervates the sternocleidomastoid and trapezius muscles

Hypoglossal nerve receives corticonuclear fibers from both hemispheres

Trigeminal nerve: V2 (maxillary nerve) exits skull via foramen rotundum

Oculomotor nerve

Facial nerve

Glossopharyngeal nerve

Trigeminal nerve

Vagus nerve
