Which membrane is composed of areolar connective tissue and not an epithelial tissue?

• A. Synovial membrane
• B. Mucous membrane
• C. Cutaneous membrane
• D. Serous membrane

Answer: (A)

Verified step by step guidance

1. Understand the types of membranes in the body: There are four main types of membranes - mucous, serous, cutaneous, and synovial. Each has distinct characteristics and functions.
2. Identify the composition of each membrane: Mucous, serous, and cutaneous membranes are composed of epithelial tissue and an underlying layer of connective tissue.
3. Focus on the synovial membrane: Unlike the other membranes, the synovial membrane is composed solely of connective tissue, specifically areolar connective tissue, without an epithelial layer.
4. Consider the function of the synovial membrane: It lines the cavities of synovial joints, producing synovial fluid for lubrication, which is crucial for joint movement.
5. Conclude that the synovial membrane is the only one composed of areolar connective tissue without an epithelial component, distinguishing it from the other membranes listed.
