Multiple Choice

Which of the following accurately describes the basement membrane that underlies epithelial tissues?

It is a layer of muscle cells that contracts to move the epithelium.

It serves as the main site of nerve impulse transmission in epithelial tissue.

It provides structural support and anchors the epithelium to underlying connective tissue.

It is composed primarily of adipose tissue and blood vessels.

Verified step by step guidance

Step 1: Understand the function of the basement membrane. The basement membrane is a specialized structure found beneath epithelial tissues. It provides structural support and acts as an anchor, connecting the epithelial layer to the underlying connective tissue.

Step 2: Analyze the composition of the basement membrane. It is primarily composed of proteins such as collagen and laminin, along with glycoproteins and proteoglycans. These components create a thin, yet strong and flexible layer.

Step 3: Eliminate incorrect options based on the function and composition of the basement membrane. For example, the basement membrane is not composed of muscle cells, adipose tissue, or blood vessels, nor does it serve as the main site for nerve impulse transmission.

Step 4: Focus on the correct description. The basement membrane provides structural support and anchors the epithelium to the underlying connective tissue, ensuring stability and facilitating nutrient exchange.

Step 5: Confirm the correct answer by matching the description to the known characteristics of the basement membrane. The correct answer is: 'It provides structural support and anchors the epithelium to underlying connective tissue.'
