Cremasteric fascia is continuous with which abdominal layer?

• A. Internal oblique
• B. External oblique
• C. Transversus abdominis
• D. Transversalis fascia

Answer: (A)

The cremasteric fascia is continuous with the internal oblique layer because the cremaster muscle itself is derived from fibers of the internal oblique as it travels through the inguinal canal. The fascia wrapping that muscle—the cremasteric fascia—remains an extension of the internal oblique’s fascia as it extends into the spermatic cord. This is why the cremasteric fascia is continuous with the internal oblique. The external oblique contributes to the external spermatic fascia, and the transversalis fascia contributes to the internal (deep) spermatic fascia, not the cremasteric fascia.
