Complete the sentences describing the ventricles and spaces associated with CSF in the central nervous system. Then place the sentences in order to describe the flow of CSF from superior to inferior. cerebellum central canal four lateral ventricles cerebral aqueduct subarachnoid space third ventricle interventricular foramina fourth ventricle three Drag the text blocks below into their correct order. The ________ is/are found within the cerebral hemispheres. This ventricle is continuous with the ________ of the spinal cord and has openings into the ________ of the meninges. It is connected to the ventricle below it by a small canal located in the midbrain called the ________. The ________ is a narrow space in the midline of the brain, just below the corpus callosum. There are ________ interconnected ventricles in the brain. The ________ is found posterior to the brainstem and anterior to the ________. These ventricles are connected to the single ventricle below it by two ________.

Step 1
The lateral ventricles, which are found within the cerebral hemispheres, serve as the initial chambers where cerebrospinal fluid (CSF) is produced and begins its flow. Show moreā¦

Beginning with the production of CSF in the lateral ventricles and the eventual emptying of the CSF into the superior sagittal sinus, place the following statements in the correct sequence: - CSF enters the cerebral aqueduct. - The medial aperture and the two lateral apertures allow CSF to enter the subarachnoid space. - Circulating CSF moves into the superior sagittal sinus via arachnoid villi. - CSF moves into the third ventricle via the intraventricular foramen. - From the cerebral aqueduct, the CSF enters the fourth ventricle.

Plexus in the fourth ventricle adds more CSF. Subdural. Aqueduct. CSF fills the space and bathes external surfaces of the brain and spinal cord. Subarachnoid. CSF is secreted into each ventricle by the choroid plexus and flows into the third ventricle where more is added. Choroid. Lateral. At arachnoid villi, CSF is reabsorbed into venous blood of venous sinuses. Frontal. Posterior. CSF then flows down the cerebral aqueduct to the fourth ventricle. Dural. CSF then flows out two lateral apertures and one aperture. Median.
