Definition
  1. Noun:
    • Anatomical passage in the lower abdomen: The inguinal canal is a narrow, tubular passage or tunnel located in the lower part of the anterior abdominal wall, just above the inguinal ligament. It serves as a conduit for structures passing between the abdominal cavity and the external genital region.
    • Sex-specific function: In biological males, it is the pathway through which the testes descend into the scrotum during fetal development and it subsequently houses the spermatic cord. In biological females, it transmits the round ligament of the uterus.
Examples of Usage
  • Noun:
    • A hernia occurs when part of the intestine protrudes through a weak spot in the abdominal wall, often through the inguinal canal.
    • During development, the testes migrate from the abdomen to the scrotum via the inguinal canal.
    • The surgeon carefully dissected the tissue to expose the inguinal canal during the repair procedure.
Advanced Usage
  • "Deep inguinal ring": The internal entrance of the inguinal canal, located within the abdominal cavity.
    • The hernia sac originated at the deep inguinal ring.
  • "Superficial inguinal ring": The external exit of the inguinal canal, an opening in the aponeurosis of the external oblique muscle.
    • The hernia became visible as it exited through the superficial inguinal ring.
Variants and Related Words
  • Inguinal (adj): Pertaining to the groin region.
    • The patient complained of inguinal pain.
  • Inguinal hernia (n): A type of hernia where abdominal contents protrude into the inguinal canal.

Synonyms

Related Phrases
  • "Contents of the inguinal canal": Refers to the structures that pass through it, which differ by sex.
    • The contents of the inguinal canal in the male include the spermatic cord.
  • "Walls of the inguinal canal": Refers to its anatomical boundaries (anterior wall, posterior wall, roof, and floor).
