Document Summary
Inguinal canal: there are three layers of the anterior abdominal wall that make their way down to the pubic tubercle and the anterior superior iliac spine towards the inguinal ligament. Lowest margin of the lower interior abdominal wall (medial) Something (intestinal structure) goes through the deep opening and through the canal and appears through the superficial opening: normal passage, direct. In the early stages, the gut is suspended in the mesentery, then the gut will push against the wall and will fixate. Fixation plays a very important role: at birth, if there is no fixation, the guts can move around and can cause strangulation which needs to be fixed by surgery and can lead to many problems. Superior mesenteric nodes around the superior mesenteric artery and drains the midgut. Inferior mesenteric nodes around the inferior mesenteric artery and drain the hindgut lymphatic system (thoracic duct) Stomach cancer would drain to the coeliac lymph nodes.
