The cremasteric muscle and fascia covering the spermatic cord are derived from which abdominal wall muscle?
- A Internal oblique ✓
- B External oblique
- C Transversus abdominis
- D Rectus abdominis
Correct answer: A. Internal oblique
Explanation
The cremasteric muscle and fascia are derived from the internal oblique muscle as the testis descends through the inguinal canal. The external oblique gives rise to the external spermatic fascia. The transversus abdominis contributes to the conjoint tendon but not to the cord coverings. The rectus abdominis does not contribute to spermatic cord layers.
