THE INGUINAL CANAL

Hello Everyone, It’s still your favourite Medic Writer and I will like to welcome us all into todays session. Today we will be discussing a major landmark in the abdominal region which is highly important for diagnosis, treatment and a major landmark during surgical operations. The abdominal region has a the highest number of viserals which are important for body metabolism.

Today we will be examining the INGUINAL CANAL.
The inguinal canal is a short passage that extends inferiorly and medially through the inferior part of the abdominal wall. It is superior and parallel to the inguinal ligament.

The canal serves as a pathway by which structures can pass from the abdominal wall to the external genitalia. It is of clinical importance as a potential weakness in the abdominal wall, and thus a common site of herniation.

In summary of that, the inguinal canal can also be liken to a normal fossa e.g Cubital, poptileal etc and every fossa must have a boundary and must also contain materials i.e contents.

The BOUNDARIES OF THE INGUINAL CANAL
The inguinal canal is bordered by anterior, posterior, superior (roof) and inferior (floor) walls. It has two openings – the superficial and deep rings.

Walls
Anterior wall – aponeurosis of the external oblique, reinforced by the internal oblique muscle laterally.

Posterior wall – transversalis fascia.

Roof – transversalis fascia, internal oblique, and transversus abdominis
.
Floor – inguinal ligament (a ‘rolled up’ portion of the external oblique
aponeurosis), thickened medially by the lacunar ligament.

The contents of the inguinal canal includes the;

The spermatic cord in males only
The round ligament in females only
The illioingunial Nerve
The genital branch of genitofemoral Nerve
