It will come together. Also, beware - there are other places in the body where some tissue defines a "passage" or a "canal". You will see this type of thing again. Get used to thinking outside of the box! See the Clinical Terms in the Anatomy Tables for full descriptions. The most important distinction to make is between direct and indirect inguinal hernias:. Also, give some thought to what coverings each would have. Here is the basic gist see also 5 below :. Male: testes begin as retroperitoneal structures in the posterior abdominal wall.
They are attached to the anterolateral abdominal wall by the gubernaculum. As the gubernaculum "pulls" the testes into the pelvis and developing inguinal canal, it is preceded by the processus vaginalis , derived from the peritoneum which lies anterior to the testes.

Gross anatomy The inguinal canal has an oblique course, is 4 cm in length and has two openings: deep inguinal ring: a round opening in the transversalis fascia found 1 cm superior to the inguinal ligament and 1 cm lateral to the inferior epigastric arteries superficial inguinal ring: a V-shaped opening in the external oblique aponeurosis that is superior and lateral to the pubic tubercle within Hesselbach's triangle 1,2 Deep inguinal ring The deep inguinal ring is bounded by the following: laterally by the angle between the transversus abdominis and inguinal ligament.
Older authors and texts refer to the deep ring as the abdominal inguinal ring. Superficial inguinal ring The superficial inguinal ring, as described, is an inverted 'V' shaped, triangular opening in the medial end of the external oblique aponeurosis, above and lateral to the pubic tubercle. Boundaries The following structures contribute to the walls of the inguinal canal 1 : superior wall roof : internal oblique muscle and transversus abdominis muscle anterior wall: external oblique aponeurosis and internal oblique aponeurosis inferior wall floor : inguinal ligament and lacunar ligament posterior wall: transversalis fascia and conjoint tendon MALT is a mnemonic to recall this.
