Long Answer: Yes, sort of. You do use a scanning microscope to start, as you will want to move the microscope to the correct location before increasing the magnification. However, you wouldn't use the scanning lens to see with high magnification.
The perivascular feet of the <u>endothelial cells</u> help create a blood-brain barrier.
<h3>What are endothelial cells?</h3>
Endothelial cells can be defined as those type of cells found in the inside lining of blood vessels, lymph vessels, and the heart.
Interestingly, the major function of the edothelial cells is that they release substances that control vascular relaxation and contraction as well as enzymes that control blood clotting, immune function and platelet (a colorless substance in the blood) adhesion.
So therefore, the perivascular feet of the endothelial cells help create a blood-brain barrier.

Let's make a Punnett square to represent this, with X representing our dominant allele and x our recessive.
