Answer:
a. inferior
b. medial
Explanation:
There are three planes that are used to divide the human body: 1-transverse plane, which is a horizontal line that divides the body into a superior (above) section and an inferior (below) section; 2-median sagittal plane, which is a vertical line that divides the body into equal left and right portions; and, 3-coronal plane, which divides the body into a ventral (anterior) section and a dorsal (posterior) section. As its name indicates, inferior is the opposite term of 'superior' and refers to a structure that is 'below' something else (for example, the feet are inferior to the head). Moreover, a medial structure refers to a structure that is closer to the midline of the body, and therefore divides the body into equal right and left sections (for example, the nose is medial to the eyes).

The cell membrane is a biological membrane that separates the interior of all cells from the outside environment. It consists of a lipid bilayer with embedded proteins. The basic function of the cell membrane is to protect the cell from its surroundings. The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules. In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled.
