Tectum Consists of superior and inferior colliculi, don’t forget SLO-AIMĬerebellum Covers the fourth ventricle, responsible for the initiation and planning of movement, cerebellar sighs are ipsilateral, midline lobe is called vermis, highly lobulated cortex is called “arbor vitae”, key cells = pyramidal, granular, and molecularĤth ventricle Contains csf, choroid plexuses, foramen luska(lateral) and magendi(medial) lead to cisterna magna and subarachnoid space. CSF leaves midbrain via aqueduct of SilviusĪqueduct of Silvius Connects 4th ventricle to 3rd ventricle, obstruction can lead to hydrocephaly, surrounded by periaqueductal gray (PAG)-related to painģrd ventricle Filled with CSF, sits between thalami and enters hypothalamus, connects to lateral ventricles via foremen of monroe, contains some choroid and also the stria medullaris thalami which connect habenula to septal nuclei Midbrain Key features: cerebral peduncles, aqueduct of Sylvius, substantia nigra, tectum (inferior and superior colliculi) red nucleus, CN III, IVįourth ventricle Contains csf, choroid plexuses, foramen luscka(lateral) and magendie(medial) lead to cisterna magna and subarachnoid space. Fed in part by the basilar artery, Many cortical pontine fibers end in the pontine gray nuclei which in turn project to the cerebellum via the MCP Pons “bridge” Covered largely by the 4th ventricle and the cerebellum. Medulla Just rostral to cervical cord, contains critical breathing centers, fed by vertebral and pica arteries (lateral wallenberg syndrome when pica is blocked) Lateral medullary syndrome (also called Wallenbergs syndrome and posterior inferior cerebellar artery syndrome) is a disease in which the patient has difficulty with swallowing or speaking or both owing to one or more patches of dead tissue (known as an infarct) caused by interrupted blood supply to parts of the brain. Pineal Secretes melatonin, seat of the soul, biological clock?, third eye in some fishes and amphibians.
