where is the location of the deep inguinal ring
1.5cm above the mid point of the inguinal ligament
what is the hasslebachs triangle and what are its boarders
it is the weakest part of the abdominal wall as there is no rectus sheath.

Boarders:
Medially: Rectus abdominus
Laterally: Inferior epigastric vessels
Inferiorally: Inguinal Ligament
What are the boarders of the inguinal canal
The borders of the inguinal canal can be recalled using the mnemonic MALT:2
Roof (Muscles): Transversus abdominis muscle, internal oblique muscle
Anterior wall (Apeunerosis): Aponeurosis of the internal and external oblique muscle
Floor (Ligaments): Inguinal ligament, lacunar ligament
Postior wall (T’s): Conjoint tendon, transversalis fascia
What is the contents of the inguinal canal
- Ilioinguinal nerve
- Genital branch of the genitofemoral nerve
- The round ligament of the uterus (Females)
- Spermatic cord (Males)
Extra:
Spermatic Cord contents:
3 fascial layers: external spermatic fascia, cremasteric fascia/ muscle, internal spermatic fascia
3 arteries: artery to vas (ductus) deferens, cremasteric artery, testicular artery
3 nerves: ilioinguinal nerve, genital branch of genitofemoral, sympathetic and visceral afferent nerve fibres
3 other: pampiniform plexus, vas deferens, testicular lymphatics
which ligament supplies the most support to the uterus
Transverse Ligament
what is the innervation of the scrotal skin?
Anterior:
