Where is the median aperture located Inferior wall just over the obex, leads to the cerebromedullar cisterna (subarachnoid space). and where does it lead? What are the lateral apertures and In the apex of the lateral recessus, leads into the pons cisterna (subarachnoid space). where do they lead? What is the level of the spinal cord L1/L2 (Lumbar vertebrae 1/Lumbar vertebrae 2). termination? Which part of the spinal cord is known C5 - T1 (Cervical vertebrae 5 - Thoracic vertebrae 1). as the cervical enlargement? What is the range of the lumbosacral L1 - S3 (Lumbar vertebrae 1 - Sacral vertebrae 3). enlargement?

Where is the choroid plexus present in In all components except for the cerebral aqueduct and the occipital and frontal horns of the lateral the ventricular system? ventricles. In which part of the lateral ventricles is In the superior part of the inferior horn. the choroid plexus found? What is the process through which Liquid filters through these cells from blood to become cerebrospinal fluid. cerebrospinal fluid (CSF) is formed? Where is cerebrospinal fluid (CSF) By the ventricles, mostly the lateral ventricles. mostly produced? At what rate is cerebrospinal fluid (CSF) 500 ml/day. Question Answer produced? What is the volume that may be 150 ml. contained by the brain? How frequently is cerebrospinal fluid 3-4 times per day (turnover). (CSF) replaced?
