Answer:
semipermeable membrane
Explanation:
Neurons are the cells of the nervous system and have the plasma membrane as their outer covering. Their plasma membrane is also made up of two layers of phospholipids and the proteins are embedded in it. Therefore, the plasma membrane of neurons is a semipermeable membrane as charged and polar substances can not cross its nonpolar core made up of the hydrophobic tails of the phospholipids.
Similarly, the substances with a larger size can also not move freely across it. A semipermeable membrane allows only certain substances to move through it.
