Question

instructions: identify the components of the extracellular matrix in the image below. then, describe the main role of each component in a tissue. ground substance in ecm: protein fibers in ecm:

Explanation:

The extracellular matrix (ECM) has two main components shown: ground - substance and protein fibers. The ground substance is a gel - like substance that fills the space between cells and fibers. It acts as a medium for diffusion of nutrients and waste products between cells and blood vessels. Protein fibers in the ECM include collagen, elastin, and fibronectin. Collagen provides tensile strength, elastin gives elasticity allowing tissues to stretch and recoil, and fibronectin helps in cell adhesion and migration.

Answer:

Ground substance: Gel - like medium for diffusion. Protein fibers: Collagen for tensile strength, elastin for elasticity, fibronectin for cell adhesion and migration.
