  • 2. 

    Adheres to diseased organs to help prevent the spread of infection.

    • Lesser Omentum

    • Greater Omentum

    Correct Answer
    A. Greater Omentum
    Explanation
    The greater omentum is a fatty apron-like structure that hangs down from the stomach and covers the intestines. It plays a role in protecting the abdominal organs and preventing the spread of infection. It adheres to diseased organs, forming a barrier that helps to isolate the infection and prevent it from spreading to other parts of the abdomen. This can help to limit the damage caused by the infection and promote healing.

    Small vertical opening -- communication between greater and lesser sac

    • Mesentery

    • Morison's Pouch

    • Infrahepatic space

    • Epiploic Foramen

    Correct Answer
    A. Epiploic Foramen
    Explanation
    The correct answer is Epiploic Foramen. The Epiploic Foramen is a small vertical opening that allows communication between the greater and lesser sacs of the peritoneal cavity. It is located posterior to the free edge of the lesser omentum and connects the greater sac (located in the main part of the peritoneal cavity) with the lesser sac (located posterior to the stomach). This opening is important for the movement of fluid and gas between these two compartments.

    The Lesser Omentum

    • Extends from the lesser curvature of the stomach to symphysis pubis

    • Extends from the liver to the greater curvature of the stomach

    • Extends from the liver to the lesser curvature of the stomach

    • Attaches to the greater curvature of the stomach

    Correct Answer
    A. Extends from the liver to the lesser curvature of the stomach
    Explanation
    The lesser omentum is a double layer of peritoneum that connects the liver to the lesser curvature of the stomach. It forms a protective covering for the structures in the upper abdomen and also helps in the movement and support of the stomach. The other options are incorrect as they do not accurately describe the location and attachment of the lesser omentum.

  • 5. 

    Spaces between the colon and the abdominal wall.

    • Perinephric spaces

    • Suprahepatic spaces

    • Infrahepatic spaces

    • Paracolic gutters

    Correct Answer
    A. Paracolic gutters
    Explanation
    Paracolic gutters are spaces located on either side of the colon, between the colon and the abdominal wall. These gutters allow for the movement and flow of fluids within the abdominal cavity. They play an important role in preventing the accumulation of fluid or infection in the abdominal region.

    Rate this question:

  • 6. 

    Which of the following structures is NOT a layer of the abdominal wall?

    • External oblique muscle 

    • Transversus abdominis muscle 

    • Rectus abdominis muscle 

    • Diaphragm

    Correct Answer
    A. Diaphragm
    Explanation
    The diaphragm is a dome-shaped muscle that separates the thoracic cavity (chest) from the abdominal cavity. It plays a crucial role in respiration. The other options are all layers of the abdominal wall, contributing to its structure and function in protecting abdominal organs and facilitating movement.

    Rate this question:

  • 7. 

    Intraperitoneal structures are

    • Liver, gallbladder, pancreas, kidneys, and ureters

    • Liver, gallbladder, spleen, majority of small intestine, ovaries

    • Kidneys, adrenal glands, pancreas, urinary bladder, aorta, IVC

    • Liver, kidneys, pancreas, spleen, majority of small intestine

    Correct Answer
    A. Liver, gallbladder, spleen, majority of small intestine, ovaries
    Explanation
    The correct answer is liver, gallbladder, spleen, majority of small intestine, ovaries. These structures are considered intraperitoneal because they are located within the peritoneal cavity, which is the space between the parietal and visceral peritoneum. The liver, gallbladder, spleen, and majority of small intestine are suspended within the peritoneal cavity by mesenteries, while the ovaries are also located within the peritoneal cavity in females. The kidneys, adrenal glands, pancreas, urinary bladder, aorta, and IVC are retroperitoneal structures, meaning they are located behind the peritoneum and are not surrounded by it.

    Rate this question:

  • 8. 

    Lesser sac is the peritoneal recess anterior to the stomach.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is false because the lesser sac is actually the peritoneal recess posterior to the stomach, not anterior to it. The lesser sac is located between the stomach and the pancreas, and it is an important anatomical feature in the abdominal cavity.

    Rate this question:

  • 9. 

    Retroperitoneal structures are

    • Pancreas, Kidneys, Ureters, Adrenal glands, Aorta, IVC, Bladder, Uterus/Prostate, Ascending and descending colon, most of duodenum

    • Pancreas, Liver, Gallbladder, Kidneys, Ureters, Uterus, Aorta, IVC, Bladder

    • Kidneys, aorta, IVD, ovaries, Uterus, spleen, bladder, ascending and descending colon, pancreas, most of the duodenum

    • Ovaries, Uterus/Prostate, Duodenum

    Correct Answer
    A. Pancreas, Kidneys, Ureters, Adrenal glands, Aorta, IVC, Bladder, Uterus/Prostate, Ascending and descending colon, most of duodenum
    Explanation
    The retroperitoneal structures are located behind the peritoneum, a membrane that lines the abdominal cavity. These structures include the pancreas, kidneys, ureters, adrenal glands, aorta, inferior vena cava (IVC), bladder, uterus/prostate, ascending and descending colon, and most of the duodenum.

    Located behind the lesser omentum and the stomach extending superior to the diaphragm.

    • Right Paracolic Gutter

    • Greater Sac

    • Lesser Sac

    • Perinephric space

    Correct Answer
    A. Lesser Sac
    Explanation
    The correct answer is Lesser Sac because it is the only option that is located behind the lesser omentum and the stomach, extending superior to the diaphragm. The other options do not match this description.

    Rate this question:

  • 11. 

    Primary compartment extending across the anterior abdomen from the diaphragm to pelvis.

    • Greater sac

    • Lesser sac

    • Paracolic gutters

    • Greater Omentum

    Correct Answer
    A. Greater sac
    Explanation
    The primary compartment that extends across the anterior abdomen from the diaphragm to the pelvis is known as the greater sac. This sac is the largest cavity within the peritoneal cavity and contains most of the abdominal organs. It is bounded anteriorly by the anterior abdominal wall and posteriorly by the vertebral column. The greater sac is divided into different regions by various structures, such as the lesser sac, paracolic gutters, and greater omentum. However, the greater sac itself refers to the main compartment that spans the entire anterior abdomen.

    Accumulation of tissue that the body cannot reabsorb, usually due to cirrhosis, neoplasm, or congestive heart failure.

    • Hematoma

    • Seroma

    • Ascites

    • Abscess

    Correct Answer
    A. Ascites
    Explanation
    Ascites is the correct answer because it refers to the accumulation of fluid in the abdominal cavity. This fluid buildup occurs when the body is unable to reabsorb the excess fluid, often due to conditions like cirrhosis, neoplasm, or congestive heart failure. Hematoma, seroma, and abscess are not related to the accumulation of fluid in the abdominal cavity, making them incorrect answers.

    Smooth muscle malignancy. Complex, with possible cystic degeneration.

    • Leiomyosarcoma

    • Desmoid

    • Rhabdomyosarcoma

    • Liposarcoma

    Correct Answer
    A. Leiomyosarcoma
    Explanation
    Leiomyosarcoma is the correct answer because it is a type of smooth muscle malignancy that can present with complex features, including possible cystic degeneration. Desmoid, Rhabdomyosarcoma, and Liposarcoma are not specifically associated with smooth muscle and do not typically exhibit cystic degeneration.

    Posterior cul-de-sac is located

    • Between the rectum and the uterus

    • Between the bladder and the uterus

    • In the inguinal canal

    • All of the above

    Correct Answer
    A. Between the rectum and the uterus
    Explanation
    The correct answer is between the rectum and the uterus. The posterior cul-de-sac is a space located in the pelvic cavity, specifically between the rectum and the uterus. It is also known as the rectouterine pouch or the pouch of Douglas. This space is important in gynecology as it can be examined during a pelvic examination and can be a site for the accumulation of fluid or blood in certain medical conditions.

    The mesentery suspends these structures from the posterior abdominal wall.

    • Large intestine

    • Jejenum, ileum, transverse colon

    • Jejenun and ileum

    • Transverse and sigmoid colon

    Correct Answer
    A. Jejenun and ileum
    Explanation
    The mesentery is a double layer of peritoneum that attaches the small intestine to the posterior abdominal wall. It suspends the jejunum and ileum, which are parts of the small intestine, from the posterior abdominal wall. Therefore, the correct answer is Jejunum and ileum.

    The falciform ligament divides this space into right and left components.

    • Subhepatic

    • Retrovesical

    • Perinephric

    • Subphrenic

    Correct Answer
    A. Subphrenic
    Explanation
    The falciform ligament is a structure in the abdominal cavity that attaches the liver to the diaphragm and separates the liver into right and left lobes. The space below the diaphragm and above the liver is known as the subphrenic space. Therefore, the falciform ligament divides this space into right and left components.

    Rate this question:

  • 18. 

    Potential space located between right lobe of the liver, right kidney, and right hepatic flexure.

    • Right Posterior Subphrenic

    • Right Subhepatic

    • Morison's Pouch

    • Right Anterior Subphrenic

    Correct Answer
    A. Right Posterior Subphrenic
    Explanation
    The right posterior subphrenic space is the potential space located between the right lobe of the liver, right kidney, and right hepatic flexure. This space is situated behind the liver and below the diaphragm. It is important to note that Morison's pouch is another name for the right posterior subphrenic space. Therefore, the correct answer is Right Posterior Subphrenic.
