Conjoined tendon is formed by the aponeuroses of which two muscles?

Explanation:
The conjoined tendon is formed by the aponeuroses of the internal oblique and the transversus abdominis. These two muscle layers fuse near the lower part of the inguinal canal and attach to the pubic crest and pectineal line, reinforcing the medial, posterior wall of the canal. The external oblique contributes to the superficial and anterior aspects of the canal, not to this conjoint tendon, and the rectus abdominis does not form this shared aponeurosis with the transversus abdominis.
