Block 6 Anatomy Abdomen Prt 2

The correct answer is sigmoid colon because the arrow is pointing to a segment of the large intestine that is located in the lower left side of the abdomen, which corresponds to the position of the sigmoid colon. The other options, such as ascending colon, descending colon, duodenum, and cecum, are located in different parts of the digestive system and are not consistent with the location indicated by the arrow.

The peritoneal cavity is the potential space between the parietal and visceral peritoneum. The parietal peritoneum lines the abdominal wall, while the visceral peritoneum covers the organs within the abdominal cavity. The peritoneal cavity allows for movement and lubrication of the organs within it. It is not a closed cavity in both sexes, as it is typically open to the testis in males. The fact that it contains lymph nodes is not mentioned in the given options.

The surgeon should be concerned about a potential spread of the cancer to the superficial inguinal lymph nodes because the lymphatic drainage of the testis is primarily to the superficial inguinal lymph nodes. Any fluid from the testis that comes into contact with the incised skin of the scrotum can potentially carry cancer cells to the lymph nodes, leading to metastasis and further spread of the cancer. Therefore, it is important for the surgeon to be concerned about this accident and take appropriate measures to prevent the spread of cancer.

Placing the patient in an inclined position with the head and trunk elevated at least 45 degrees helps to minimize the spread of peritoneal fluid via the paracolic gutters from a lower abdominal infection. This position utilizes gravity to prevent the fluid from flowing towards the diaphragm and potentially causing further complications. It allows the fluid to pool in the lower abdomen, reducing the risk of it spreading to other areas of the peritoneal cavity.

The omental bursa is a completely sealed-off recess of the peritoneal cavity located anterior to the stomach. It has medial and lateral recesses and contains the portal vein. However, the most relevant information in this context is that the omental bursa can contain pancreatic fluid following rupture of the pancreas. This suggests that the omental bursa acts as a potential space where pancreatic fluid can accumulate in case of pancreatic injury or rupture.

A hydrocele is a condition characterized by the accumulation of excess fluid in the scrotum. It is typically caused by a persistent processus vaginalis, which is a small pouch of peritoneum that extends into the scrotum during fetal development. This condition is not typically associated with a direct inguinal hernia, which is a separate condition involving the protrusion of abdominal contents through the inguinal canal. Therefore, the statement that a hydrocele is typically associated with a direct inguinal hernia is not true.

The given answer is incorrect because a mesentery is indeed sensitive to laceration near its attachment to organs. Laceration refers to a deep cut or tear in the skin or flesh, which can cause severe damage. Since the mesentery attaches organs to the body wall and contains blood vessels and nerves, any laceration near its attachment can potentially harm these structures. Therefore, the correct statement should be that a mesentery is sensitive to laceration near its attachment to organs.

The superior mesenteric artery does not lie anterior to the neck of the pancreas.

The rete testis is a network of tubules within the testicle that connects the seminiferous tubules to the efferent ductules. It does not directly open into the ductus deferens. The correct association is that the rete testis connects to the efferent ductules, which then open into the ductus deferens.

Based on the given information, the correct answer is "ileocolic". The image is an arteriogram of the superior mesenteric artery and its branches. The arrow indicates a specific artery, and based on its location and course, it corresponds to the ileocolic artery.

The arrow in the enhanced radiograph is pointing to the left hepatic duct. This can be determined by analyzing the anatomy of the biliary system and identifying the structures present in the image. The left hepatic duct is one of the main ducts that carries bile from the liver. It is located on the left side of the liver and connects to the common hepatic duct. Therefore, based on the information provided, the correct answer is the left hepatic duct.

Pancreatic cancer is known to have a high rate of metastasis, meaning it can spread to other parts of the body. This is because the pancreas is rich in blood vessels and lymphatic channels that allow cancer cells to travel to distant sites. Therefore, the association between pancreatic cancer and rarely metastasizing is incorrect.

Based on the knowledge that the spleen was ruptured, it is least likely that the spleen must be repaired or your friend will die. While a ruptured spleen can be a serious medical condition that requires immediate attention, it does not necessarily mean that the spleen must be repaired in order for the friend to survive. In some cases, the spleen may be removed or the bleeding may be controlled without repairing the spleen. Other options such as blood transfusions or surgical interventions may be considered to manage the situation.

Paracentesis is a medical procedure that involves the removal of fluid from the peritoneal cavity, typically for diagnostic or therapeutic purposes. It is not used for the withdrawal of urine from the bladder. Therefore, the association between "withdrawal of urine from bladder" and "paracentesis" is incorrect.

The correct answer is "It occurs near the junction between the jejunum and the ileum." This is least likely pertaining to an ileal diverticulum because ileal diverticula typically occur on the antimesenteric border of the ileum, not near the junction between the jejunum and the ileum.

The superior mesenteric artery is accompanied by the superior mesenteric vein on its right. This means that the vein runs parallel to the artery on its right side. This anatomical relationship is important for the venous drainage of the intestines.

Esophageal varices are not associated with blockage of the inferior vena cava. Esophageal varices are enlarged veins in the lower part of the esophagus that occur due to increased pressure in the portal vein system, which is often caused by liver cirrhosis. The increased pressure in the portal vein system leads to the development of collateral veins, including esophageal varices. These varices can rupture and cause life-threatening bleeding. Blockage of the inferior vena cava does not directly cause esophageal varices.

The correct answer is because the pain is first conveyed via sympathetic fibers that enter the spinal cord at the T10 level and then by somatic fibers in the parietal peritoneum of the abdominal wall. This is because the appendix is innervated by sympathetic fibers that enter the spinal cord at the T10 level. Initially, the pain is felt in the periumbilical region due to the convergence of visceral afferents from the appendix and other abdominal structures onto the same level of the spinal cord. As the inflammation progresses, the pain becomes localized to the right lower quadrant due to the somatic fibers in the parietal peritoneum being more sensitive and specific in localizing pain.

The teniae coli may be used during an appendectomy to locate the appendix. The teniae coli are three bands of longitudinal muscle that run along the length of the large intestine. They are visible on the outer surface of the colon and can be used as a landmark to locate the appendix during surgery. By following the teniae coli, surgeons can accurately locate the appendix and remove it if necessary. This is an important step in an appendectomy procedure.

The sigmoid arteries do not serve as the main source of blood to the left ureter. Instead, they supply blood to the sigmoid colon and rectum. The left ureter receives its blood supply from the renal arteries.

The most likely cause of the patient's pain and signs is the small clot that was freed from her aorta during the accident. This clot then entered and blocked the vasa recta, which are the blood vessels that supply the ileum of the small bowel. This blockage leads to a lack of blood flow and oxygen to the affected area, causing colicky abdominal pain, vomiting, and distension of the abdomen. This explanation is supported by the symptoms described and the mechanism of clot formation and occlusion.
