• These consist of the following: During development each gonad (ovary or testicle) descend from their starting point on the posterior abdominal wall (para-aortically) from the labioscrotal swellings near the kidneys, down the abdomen, and through the inguinal canals to reach the scrotum. (wikipedia.org)
  • 3 nerves: genital branch of the genitofemoral nerve (L1/2), sympathetic and visceral afferent fibres, ilioinguinal nerve (N.B. outside spermatic cord but travels next to it) Note that the ilioinguinal nerve passes through the superficial ring to descend into the scrotum, but does not formally run through the canal. (wikipedia.org)
  • Although cryptorchidism nearly always refers to congenital absence or maldescent, a testis observed in the scrotum in early infancy can occasionally "reascend" (move back up) into the inguinal canal. (wikipedia.org)
  • A testis which can readily move or be moved between the scrotum and canal is referred to as retractile. (wikipedia.org)
  • Cutting the skin in the scrotum may disrupt this and cancer may spread to the inguinal lymph nodes, making surveillance and subsequent operations more difficult. (wikipedia.org)
  • The scrotum remains connected with the abdomen or pelvic cavity by the inguinal canal. (wikipedia.org)

  • Testes are often palpable in the scrotum or inguinal canals, and the karyotype is XY. (wikipedia.org)
  • Images of both scrotum and bilateral inguinal regions are obtained in both transverse and longitudinal planes. (wikipedia.org)
  • citation needed] During embryogenesis, the testis descends through the inguinal canal, drawing a diverticulum of peritoneum into the scrotum as it descends. (wikipedia.org)
  • In human males, the cremaster muscle is a thin layer of skeletal muscle found in the inguinal canal and scrotum between the external and internal layers of spermatic fascia, surrounding the testis and spermatic cord. (wikipedia.org)
  • As a young male animal reaches puberty, the testicles, which originally were inside the abdominal cavity, move down the inguinal canal to the scrotum. (wikipedia.org)
  • Each crosses obliquely over the ureter and the lower part of the external iliac artery to reach the abdominal inguinal ring, through which it passes, and accompanies the other constituents of the spermatic cord along the inguinal canal to the scrotum, where it becomes tortuous, and divides into several branches. (wikipedia.org)
  • Blood supply and lymphatic drainage of the testes and scrotum are distinct: The paired testicular arteries arise directly from the abdominal aorta and descend through the inguinal canal, while the scrotum and the rest of the external genitalia is supplied by the internal pudendal artery (itself a branch of the internal iliac artery). (wikipedia.org)
  • Lymphatic drainage of the testes follows the testicular arteries back to the paraaortic lymph nodes, while lymph from the scrotum drains to the inguinal lymph nodes. (wikipedia.org)
  • The undescended testicle may be located within the normal line of descent (for example, in the inguinal canal) or high in the scrotum or ectopically (i.e. the abdomen). (wikipedia.org)
  • This is at first a slender band, extending from that part of the skin of the groin which afterward forms the scrotum through the inguinal canal to the body and epididymis of the testis. (wikipedia.org)
  • The positions of the ectopic testis may be: in the lower part of the abdomen, front of thigh, femoral canal, skin of penis or behind the scrotum. (wikipedia.org)
  • It begins at the adductor canal (also known as Hunter's canal) and is a continuation of the popliteal vein. (wikipedia.org)
  • The descending genicular artery is a small branch that arises from the femoral artery near its termination within the adductor canal. (wikipedia.org)
  • It should not be confused with the nearby adductor canal. (wikipedia.org)
  • Deep to sartorius and its fascia is the adductor canal, through which the saphenous nerve, femoral artery and vein, and nerve to vastus medialis pass. (wikipedia.org)
  • Most sources define the large intestine as the combination of the cecum, colon, rectum, and anal canal. (wikipedia.org)
  • Some other sources exclude the anal canal. (wikipedia.org)
  • Intersphincteric groove or Hilton's white line is a boundary in the anal canal. (wikipedia.org)
  • This line represents the transition point from non-keratinized stratified squamous epithelium of the anal canal to keratinized stratified squamous epithelium of the anus and perianal skin. (wikipedia.org)
  • it forms a loose sheath for the rectum, but is firmly attached around the anal canal. (wikipedia.org)
