The outer casing of the cytoplasm of a cell, which allows controlled movement of materials in and out.

Use in clinical context

The cellular membrane is the gateway in and out of the cell. If this does not function correctly important molecules cannot cross the membrane or may cross when they shouldn’t. Several genetic conditions affect the cell membrane. An example of a genetic condition caused by a malfunctioning cellular membrane is cystic fibrosis.
