Surgery MCQ Answer 68

Answer: a, b, c

The external oblique muscle and its aponeurosis, with its inferiorly and medially-directed fascicles and the overlying innominate fascia lie deep to the subcutaneous tissue. The inguinal ligament (Poupart’s ligament) is the inferior edge of the external oblique aponeurosis and extends from the anterior superior iliac spine to the pubic tubercle, turning under itself posteriorly and then superiorly to form a shelving edge. Medially, the inguinal ligament turns under even further to form the lacunar ligament, as part of its insertion on the pubis. The superficial inguinal ring is a triangular opening in the external aponeurosis, with its apex superiorly in position slightly above and lateral to the pubic tubercle, through which the cord exits the inguinal canal. The conjoined tendon is commonly alluded to in descriptions of inguinal hernia repairs. The conjoined tendon is the fusion of the aponeurosis of the internal oblique and transversus abdominis muscles.
