CHAPTER 4 STRUCTURE AND CELL BIOLOGY OF THE NEURON
... The cell membrane of a neuron is semipermeable. This means that some ions can go through but others cannot. The cell membrane contains specialized pores or ion channels that allow specific ions (e.g., sodium [Na+], potassium [K+], chloride [Cl-], or calcium [Ca++] to pass through under certain condi ...
