3. At the end of this chapter, you will
be able to understand the following
topics :
***
1. Inguinal Ligament
2. Inguinal Canal
3. Inguinal hernia
4. Factors acting and protecting
the inguinal canal
4. INGUINAL LIGAMENT
( poupart’s ligament )
FORMATION :
External Oblique aponeurosis
(EOA). Inferior border of EOA is
thickened and folded on its inner side
to form inguinal ligament.

17. SPECIFIC POINTS OF INGUINAL
CANAL :
Inguinal Canal is narrow in
females then males, and so the
males are more prone to inguinal
hernia.
Inguinal canal is straight in
children due undifferentiation of
muscles.
24. 1) Flap - Valve Mechanism (Obliquity of inguinal
canal)
2) Superficial inguinal ring is supported by reflection
of inguinal ligament and also by conjoint tendon
3) Deep inguinal ring is supported by fibres of
internal oblique muscles
4) Shutter Mechanism of internal oblique muscles
5) Ball-Valve Mechanism
6) Slit-Valve Mechanism
7) Hormonal Mechanism
