Inguinal Canal Flashcards
It allows structures of spermatic cord to pass to and from the —— to the —— in male
• Permits the passage of round ligament of uterus from the —— to the ——in female
It allows structures of spermatic cord to pass to and from the testis to the abdomen in male
• Permits the passage of round ligament of uterus from the uterus to the labium majus in female
It allows structures of ———to pass to and from the testis to the abdomen in male
• Permits the passage of ——— from the uterus to the labium majus in female
It allows structures of spermatic cord to pass to and from the testis to the abdomen in male
• Permits the passage of round ligament of uterus from the uterus to the labium majus in female
It is an —— passage through the lower part of the anterior abdominal wall
Oblique
Is it present in both sexes
T
Transmits ——— nerve in both sexes
Transmits ilioinguinal nerve in both sexes
Inguinal Canal
• It is about — inches or —cm long in the adults
• Extends from the ——-ring downward and
medially to the ——- ring
• Lies parallel to and immediately above the ——
• In the newborn child, the deep ring lies almost directly —— to the superficial ring
Inguinal Canal
• It is about 1 1⁄2 inches or 4cm long in the adults
• Extends from the deep inguinal ring downward and
medially to the superficial inguinal ring
• Lies parallel to and immediately above the inguinal ligament
• In the newborn child, the deep ring lies almost directly posterior to the superficial ring
Deep inguinal ring
Is an —— shaped opening in the ——
• Lies about — inch (—cm) above the ——midway between the —— and the ——
• Margins of the ring give attachment to the ——
Is an oval opening in the fascia transversalis
• Lies about 1⁄2 inch (1.3cm) above the inguinal ligament midway between the anterosuperior iliac spine and the symphysis pubis
• Margins of the ring give attachment to the internal spermatic fascia
Superficial Inguinal Ring
• —— in shape
• Defect in the aponeurosis of the ——muscle
• Lies immediately above and medial to the ——
• Its margins some times called ——), give attachment to the ——-
Superficial Inguinal Ring
• Triangular in shape
• Defect in the aponeurosis of the external
oblique muscle
• Lies immediately above and medial to the pubic tubercle
• Its margins some times called crura(Med & lat crus), give attachment to the external spermatic fascia
The anterior wall is made up of the —— muscle throughout, and is reinforced by the ———laterally.
The ——— lies even more laterally as part of the anterior abdominal wall
The anterior wall is made up of the external oblique muscle throughout, and is reinforced by the internal oblique m. laterally.
The transversus abdominus m. lies even more laterally as part of the anterior abdominal wall
The conjoint tendon attaches to the ——, reinforces the —— wall medially and also forms the —— of the canal
The conjoint tendon attaches to the pubic crest, reinforces the posterior canal wall medially and also forms the ROOF of the canal
The ——— and ———. combine to form the CONJOINT tendon that arches over the contents of the inguinal canal
The transversus abdominis and internal oblique mm. combine to form the CONJOINT tendon that arches over the contents of the inguinal canal
The transversus abdominis and internal oblique mm. combine to form the —— tendon
Conjoint tendon
The posterior wall is formed by —— throughout and the —— medially. The wall is particularly weak over the ——
The posterior wall is formed by transversalis fascia throughout and the conjoint tendon medially. The wall is particularly weak over the deep inguinal ring
The floor is formed by an incurving of the ———, which is part of the ——-muscle, forming a gutter. (Medially it forms the ——- ligament
The floor is formed by an incurving of the inguinal ligament, which is part of Floor
the external oblique muscle, forming a gutter. (Medially it forms the lacunar
ligament which is not illustrated)
Roof is formed by the ————
and the ———
Roof is formed by the conjoint tendon
and the meeting of the anterior and
posterior walls of the canal
