The partition that separates the two lateral ventricles is called the:

a.
wall of Sylvius

b.
septum of Monro

c.
septum pellucidum

d.
septum ventriculus

Expert Solution

Correct option is C. Septum pellicidum.

The two lateral ventricles, one in each cerebral hemisphere, form the largest component of the ventricular system. They occupy a considerable part of the cerebral hemisphere and are separated from each other by the septum pellucidum, extending between the corpus callosum and the fornix. The 3rd ventricle is a narrow slit-like cavity of the diencephalon. The two lateral ventricles are connected with the 3rd ventricle via the interventricular foramina (of Monro). The 3rd ventricle communicates via the cerebral aqueduct of midbrain with the 4th ventricle, a cavity within the hindbrain.
The 4th ventricle in turn is continuous with the central canal of the spinal cord. The central canal has a small dilatation at its inferior end, the terminal ventricle.
The cerebrospinal fluid (CSF) is formed in the ventricles
by the choroid plexuses and passes through apertures in the roof of 4th ventricle into the subarachnoid space around the brain and spinal cord.

True or False: T or F - Choroid plexuses are found only in the lateral ventricles of the brain. T or F - A lumbar spinal tap involves the removal of CSF from the epidural space. T or F - The “gateway to the brain” is the medulla oblongata. T or F - A patellar reflex involves interneurons in several segments of the spinal cord.

The human heart has four chambers (two atria and two ventricles). In the human foetus, there is an opening between the right and left atria, and they function as one atrium. This opening closes after the birth. In some cases, it does not close completely. In most of these cases, this incomplete closure remains undetected throughout life. If a large opening occurs between the right and left ventricles, as seen in normal reptiles, children with this condition cannot survive without...

Suppose that the partition coefficient for an amine, B, is K = 3.0 and the acid dissociation constant for BH+ is Ka = 1.0 x 10−9. If 50.0 mL of 0.010 M aqueous amine is extracted with 100.0 mL of solvent two times, what percentage amine remains in aqueous solution if the pH of the aqueous phase is 9.00?
