Show Answers:

  1. herniation
    -a weakness in the abdominal muscle through which a segment of the bowel or other abdominal structure protrudes
  2. indirect inguinal hernia
    sac formed from the peritoneum that contains a portion of the intestine or omentum. hernia pushes downward at an angle into the inguinal canal

    in males the hernia may descend into the scrotum
  3. direct inguinal hernia
    passes through a weak point in the abdominal wall
  4. femoral hernia
    protrudes through the femoral ring. a plug of fat in the femoral canal enlarges and eventually pulls from the peritoneum and often urinary bladder into the sac
  5. umbilical hernia
    congenital or acquired.

    congenital umbilical hernia appear at infancy

    acquired umbilical hernia directly result from increased intra abdominal pressure-most commonly in obese people
  6. incisional or ventral hernia
