Which term describes a fibrous connective tissue membrane that may be separate from other structures?

• A. Fascia
• B. Gerota's fascia
• C. Capsule
• D. Periosteum

Answer: (A)

Fascia is the fibrous connective tissue membrane that can exist as a distinct plane separating structures. It forms compartments and envelopes around muscles, vessels, nerves, and organs, and on ultrasound it often appears as thin, echogenic lines that define boundaries and can be dissected away from adjacent tissues. This general membrane can be separate from surrounding structures, which is what the item describes. The other terms describe more specific envelopes: a capsule encloses a particular organ, periosteum lines bone, and Gerota's fascia is a specific renal fascia. Because the question points to a general connective tissue plane that may be a separate layer, fascia is the best fit.
