Which of the following is a correct statement? The superior sagittal sinus lies in the falx cerebelli. Cerebrospinal fluid enters the venous circulation through the arachnoid granulations. A blocked interventricular foramen will result in an increase in pressure in the third ventricle. Cerebrospinal fluid circulates in the space between the arachnoid and dura mater.

Which is NOT a factor in the formation of the blood-brain barrier? Endothelial cells of the capillaries have few pinocytotic vesicles. Endothelial cells of the capillaries have restricted membrane permeability. Endothelial cells of the capillaries contain large gaps between the cells. Endothelial cells of the capillaries are tightly linked together.

Endothelial cells of the capillaries contain large gaps between the cells.

In what way is the dura mater of the brain different from the dura mater of the spinal cord? The dura mater of the brain is an incomplete structure. The dura mater of the brain and the dura mater of the spinal cord are identical. The dura mater of the brain is thinner. The dura mater of the brain is made of two separate layers.

If Dr. Taylor's stroke involved a blood clot in a similar location in her right hemisphere instead of her left hemisphere, __________. she would be able to read, write, and do math, but only if she is right-handed her left arm would be paralyzed, but she would still lack language and math skills her right arm would be paralyzed, but she would retain her language and math skills her left arm would be paralyzed, but she would retain her language and math skills

her left arm would be paralyzed, but she would retain her language and math skills The primary motor cortex governing the left side of the body is damaged in this case.
