PATHOLOGY

Detailed explanation-1: -In addition to coordinating cell behavior, basement membranes also directly regulate tissue shape through patterned physical constrictions.

Detailed explanation-2: -As seen with the electron microscope, the basement membrane is composed of two layers, the basal lamina and the reticular lamina.

Detailed explanation-3: -In order to heal after injury-whether by regeneration or scarring-cells must enter and progress through the cell cycle, a tightly-regulated process that consists of two main activities: DNA replication and mitosis.

Detailed explanation-4: -The basement membrane is formed by a mixture of molecules, including type IV collagen (i.e., the structural protein found in the basement membrane, the lens of the eye, and the cochlea of the ear) primarily and laminin (i.e., a glycoprotein, or protein that contains oligosaccharide chains).
