The inguinal ligament is formed by a thickening of the lower edge of the external oblique abdominal muscle. Here are the steps:

1. The external oblique muscle is one of the outermost muscles in the lateral (side) part of the abdomen.

2. The lower edge of this muscle extends from the anterior superior iliac spine (a bony projection on the uppermost part of the hip bone) to the pubic tubercle (a forward-projecting bump on the front part of the pubic bone).

3. This lower edge of the external oblique muscle thickens and folds back on itself, forming a band-like structure.

4. This band-like structure is the inguinal ligament. It serves as a boundary of the inguinal canal and provides a passageway for structures such as the spermatic cord in males and the round ligament in females to pass from the abdomen to the external genitalia.
