That portion of the aponeurosis which extends between the anterior superior iliac spine and the pubic tubercle is a thick band, folded inward, and continuous below with the fascia lata; it is called the inguinal ligament.
22.
Below the notch is the anterior inferior iliac spine, which ends in the upper lip of the acetabulum; it gives attachment to the straight tendon of the Rectus femoris and to the iliofemoral ligament of the hip-joint.
23.
In a recent study it was found to be in a region between the mid-inguinal point ( situated midway between the anterior superior iliac spine and the pubic symphysis ) and the midpoint of the inguinal ligament ( i . e . midway between the anterior superior iliac spine and the pubic tubercle ).

In a recent study it was found to be in a region between the mid-inguinal point ( situated midway between the anterior superior iliac spine and the pubic symphysis ) and the midpoint of the inguinal ligament ( i . e . midway between the anterior superior iliac spine and the pubic tubercle ).
25.
Below, it has the following attachments : posteriorly, to the whole length of the iliac crest, between the attachments of the transverse abdominal and Iliacus; between the anterior superior iliac spine and the femoral vessels it is connected to the posterior margin of the inguinal ligament, and is there continuous with the iliac fascia.
26.
Of these, the uppermost, situated at the junction of the crest and anterior border, is called the anterior superior iliac spine; its outer border gives attachment to the fascia lata, and the Tensor fasci?lat? its inner border, to the Iliacus; while its extremity affords attachment to the inguinal ligament and gives origin to the sartorius
27.
It is joined with that of the opposite muscle along the middle line, and covers the whole of the front of the abdomen; above, it is covered by and gives origin to the lower fibers of the pectoralis major; below, its fibers are closely aggregated together, and extend obliquely across from the anterior superior iliac spine to the pubic tubercle and the pectineal line.
