1

Boundaries of the inguinal canal

Anterolaterally - inguinal ligament
Between deep ring and superficial ring

2

Anterior border of inguinal canal

Aponeurosis of external oblique

3

Floor of inguinal canal

Inguinal ligament (from external oblique)

4

Medial floor of inguinal canal

Lacunar ligament

5

Posterior border of inguinal canal

Transversalis fascia

6

Posterioromedial border of inguinal canal

Conjoint tendon

7

What blood vessels are found in the spermatic cord?

Testicular a.
Cremasteric a.

Ductus deferens a.

Pampiniform plexus

8

Testicular a. source and supply

Comes off aorta beneath renal a.
Oxygenates testicles

9

Cremasteric a. source and supply

Comes off inferior epigastric a.
Oxygenates cremaster muscle

10

Ductus deferens a. source and supply

Comes off inferior vesicular a.
Oxygenates ductus deferens

11

Nerves in the spermatic cord

Genital n.
Sympathetics with testicular a. and ductus deferens

Parasympathetics from splanchnics S2-S4 on ductus deferens

12

Genital n.

Branch of the genitofemoral n.
Innervates cremaster muscle

13

Innervation of Dartos muscle

From sympathetic nerves running with ilioinguinal and posterior scrotal nerves
These are NOT in the spermatic cord, but ARE in the inguinal canal

14

Subcostal (T12)

16

Right - IVC
Left - left renal vein

17

Conjoint tendon

Fusion of the aponeurosis of the internal oblique and transversus abdominus
Fuse onto pubis
