Question 1
There are several ventricles in the brain.
Put the correct choice in the sentence. The same choice can be used more than one time.
The brain ventricles (in numerical order) are: lateral, third and [3]. There are two [4] ventricles, and one of each of the other two ventricles. The [5] ventricle is located in the diencephalic region and the [6] ventricle is located in the brainstem. The two lower ventricles are connected by the [9]. The [10] ventricle is continuous with the CSF region that is not part of the brain, the [11] of the [12].
