Sodium ions move into the cells, and the cells get a

facilitated diffusion.

Explanation:

Sodium ions pass through specific channels in the hydrophobic barrier formed by membranes proteins. this means of crossing the membrane is called facilitated diffusion, because the diffusion across the membrane is facilitated by the channel. in this case, sodium must move, or be pumped, aganist a concentration gradient.
