Apical and Basal Surface of Epithelial Tissue
This means the apical surface usually faces towards the external environment while the basal membrane faces the basement membrane. For instance in skin while apical side is supposed to be more exposed to external environment the basal side is suppose to signals to deeper layers of skin and form firm attachment with basement membrane. Pin On Epithelial Tissue In epithelia the apical surface faces the external environment or lumen of the tissue and the basal surface faces the basement membrane. . These include regulating the. The basal side of the cell is the side that faces the basement membrane ie. For this reason epithelia is described as exhibiting apical basal polarityMost apical surfaces have microvilli small extensions of the plasma membrane that. Describe the positional relationship between the epithelial surface cells basal surface basement membrane and connective tissue. Not both sides of epithelial linings are sam...
