Final answer:
The components of the extracellular matrix that constitute the basement membrane surrounding a foot wound are collagen, elastin, hyaluronic acid, and laminin. These components provide structural support, elasticity, lubrication, and aid in cell attachment, which are crucial for the wound-healing process.
Step-by-step explanation:
The basement membrane is a specialized form of the extracellular matrix (ECM) that provides support and a structural framework for cells and tissues. This matrix is composed of various substances that contribute to its function. The components that constitute the extracellular matrix and are likely to be found in the basement membrane surrounding a patient's foot wound include:
- Collagen: The most abundant protein in the ECM, which provides strength and structural support.
- Elastin: A protein that gives the ECM elasticity and the ability to return to its original shape after stretching or contracting.
- Hyaluronic acid: A glycosaminoglycan that contributes to the bulkiness of the ECM, providing lubrication and enabling the ECM to resist compressive forces.
- Laminin: A glycoprotein that is a significant component of the basement membrane, aiding in cell attachment.
Therefore, the correct answers to the question would be: a) Collagen b) Elastin c) Hyaluronic acid d) Laminin, as these are all components found within various forms of extracellular matrixes, including the basement membrane.
