A
- Deep inguinal ring = transversalis fascia
- Superficial inguinal ring = external oblique aponeurosis
2

A
- From the abdominal wall
- To external genitalia
3
Q
Contents of the inguinal canal
A
- Spermatic cord (male)
- Round ligament (female)
- Ilioinguinal nerve
- Genital branch of genitofemoral nerve
4
Q
What does the ilioinguinal nerve provide?
A
Sensory innervation of genitalia
5
Q
What does the genital branch of genitofemoral nerve do in males and females?
A
- M = supplies cremaster muscle and anterior scrotal skin
- F = supplies skin of mons pubis and labia majora
6
Q
Types of inguinal hernia
A
- Direct
- Indirect
7
Q
What is an indirect inguinal hernia and what causes it?
A
- Peritoneal sac (with or without bowel loops) enters canal through deep inguinal ring
- Enters lateral to epigastric vessels
- Caused by failure of processus vaginalis to regress
8
Q
What is a direct inguinal hernia and what causes it?
A
- Peritoneal sac bulges into canal via posterior wall of canal
- Enters medial to epigastric vessels
- Caused by weakened abdominal musculature
9
Q
What does the inguinal ligament run between?
A
- ASIS
- Pubic tubercle
10
Q
What is the inguinal ligament made of?
A
Aponeurosis of external oblique
11
Q
What is the inguinal ligament a site of attachment for?
A
- Internal oblique
- Transversus abdominis
12
Q
