(redirected from Apical surface)

apical membrane

the microvilli-bearing portion of the epithelial cell membrane at the secretory pole.

apical membrane

the layer of plasma membrane on the apical side (the side toward the lumen) of the epithelial cells in a body tube or cavity, separated from the basolateral membrane by the zonula occludens.
