Here are the essential concepts you must grasp in order to answer the question correctly.
Extracellular Matrix (ECM)
The extracellular matrix is a complex network of proteins and carbohydrates that provides structural and biochemical support to surrounding cells. It plays a crucial role in tissue and organ function, influencing cell behavior, migration, and differentiation. Understanding the ECM is essential for studying tissue engineering and regenerative medicine.

Fibrous Proteins
Fibrous proteins are one of the major components of the extracellular matrix, primarily providing structural support. Key examples include collagen and elastin, which contribute to the tensile strength and elasticity of tissues. These proteins are essential for maintaining the integrity and resilience of various tissues, such as skin, tendons, and ligaments.

Ground Substance
Ground substance is the non-cellular component of the extracellular matrix, consisting of water, glycoproteins, and proteoglycans. It serves as a medium through which nutrients and waste products can diffuse between blood vessels and cells. The ground substance also plays a vital role in cell signaling and the regulation of cellular activities within the tissue.
