what is the tunica flava abdominis and its function? with which muscle is it associated?
Hypertrophy of the external abdominal oblique muscle results in a prominent difference in thickness of the muscle and tendinous parts of the external oblique muscle. This thickening results in an observable line along the muscle tendon junction. Heaves is a lay term for forced expiration. Therefore, the exaggerated muscle tendon junction of the external oblique muscle is referred to as a heave line. The ventral part of the external oblique muscle is covered with an elastic deep fascia known as the tunica flava (yellow) abdominis.
