| semipermeable membrane |
limits the flow between inside and outside of the neuron. Water, oxygen, urea, carbon dioxide flow freely. Other substances flow poorly or not at all. A few important ions potassium, chloride, and sodium, cross the membrane through gates (or pores) in specialized proteins embedded in the membrane.
