Final answer:
Direct and indirect inguinal hernias differ in their anatomical location and the structures involved. A direct inguinal hernia occurs medial to the inferior epigastric artery, while an indirect inguinal hernia passes through the deep inguinal ring and inguinal canal.
Step-by-step explanation:
Direct and indirect inguinal hernias are two types of hernias that occur in the inguinal region of the body. However, they differ in their anatomical location and the structures involved.
A direct inguinal hernia occurs when the abdominal contents protrude through a weakened area in the abdominal wall medial to the inferior epigastric artery. This type of hernia often occurs in older individuals and is typically caused by a weakening of the transversalis fascia.
An indirect inguinal hernia, on the other hand, occurs when abdominal contents protrude through the deep inguinal ring, pass through the inguinal canal, and enter the scrotum or labia majora. This type of hernia is usually congenital and more common in males.
