Ventricles of Esain Boain has ventides. a hollow fluid filled Cavites Callal Inside the ventricle there is a ribbon like structure called chosad plexus that makes Caled SF. clear coloneless fluid. Ventricle Ventricular system is a set Cavities 94 interconnected in the brain, ewhere CSF is produced. The system consist of 4 ventricles: a) lateral ventricles right and lest b) The Fourth Ventricle -The two ventricles alesp within the Cerebral hemisphere called the lateaxy vontricle. -The lateral ventricle connect with the ventricle through the foramen I Monso third separate oponing called -The god ventricle connat with the fourth vastoide hisagh a long Sylvi nation he tube called the aques - From the Space furth Ventricle CSE flocos into the ubaide where it bathes and Cautions the brain. - CSF is recycled by the Special structures in the Superior Sagittal Schem called arachnoid villi. - A balance is alecays maintained blew the amount Et CSF absorbed and the amount produced. Any disouphorn blockage in the system result in enlargement of ventrich and the condition is called Hydrocephalus Lateral ventill - Situated in right and left side of coubraal herpe It is C-shaped It has 3 horm and central part (bully) a) Anterior hom - t'o fountal lobe b) Posterior hom occipital lobe c) In fomos hom - m Temporal lobe a) cortoul bo ly - in parietal lobe Anterior hom Antenor horn conects to the gord ventricle through foramers of magnurn. It lies astersor to the foo contral poat 4 The extension is triangular in cross section and it has a roof, floor and medial wall. < It is closed antenoly by the corpus callosum. Floos is formed by bead of corelate reichen. The medial wall is formed by septum pellucidum. A Posterios hoon It extends posteršolaterally into occipital lobe. 4 It has a roof, lateral wall and a medial conll * The 2008 and lateral cocall is formed by tapetuo. & The medial wall shocos e elevation, one superser and one inferior, known as Calcas aus. * leigat comporront of latersal ventricle Begins at the posterio end of centok zugion 100 and runs anterolaterally into temporal lite It has an anterior end, floor and look. & The roof is formed by tapetum. The floos g in ferior hoon is formed by hippocampus & Lateral part of hum has a Collateral emibace elevation called The floor Exterals from optre Chiasma anterndy and aquedud 9 Sylvius pesterosly Antenor porobon is formed by hypothalamus Posterios portion is formed by midbrain. Roof Extends from foramen y monxo suppaporneal scess postamory. antasiarly to 4 Roof has 4 separate layers 1) Neural lajes 2) Tela choroida (2 leyess) 3) Vascular layer Walls Anterior coall: Extends foon fosames g mongo Supermally to optic chicama informooly Postersos coall: Extends from Suprapineal recess Supersoly to cquirenct of Sylvius mferiorly. Lateral coall: formed by medial aspect of the thalamus and hypothalamus, which are Separated by hypothalamus sulcus.
