Anterior Abdominal Wall: Review Questions
1. Which of the following is true of the parietal layer of a serous membrane?
In the thoracic region it could be called pleura or pericardium
In the abdominal region it covers the diaphragmatic surface of the liver
Surrounding the heart, it may also be called epicardium
In the abdomen it is in direct contact with the transversus abdominis muscle without intervening fascia
None of the above
2. Peritoneum:
Is formed by stratified squamous epithelium
Of both parietal and visceral types, is insensitive to pain
Is normally about 5 mm thick
Normally has a minute amount of serous fluid lubricating its surface
Covers all surfaces of all parts of the small intestine
3. Which of the following is normally found in the left upper quadrant of the abdomen?
Right lobe of the liver
Ligamentum teres hepatis
Splenic flexure of the large intestine
Gallbladder
Vermiform appendix
4. All of the following are boundaries of the abdominal cavity EXCEPT the:
Respiratory diaphragm
Pelvic inlet
Lumbar vertebral bodies
Shafts of the ribs
Rectus abdominis muscle
5 The nerves of the abdominal wall:
Are all branches of intercostal nerves
Include a branch of T7 that innervates the skin around the umbilicus
In the midaxillary line are located between transversus abdominis and internal oblique
Contain no autonomic nerve fibers
Are branches of dorsal primary rami
6 Which of the following is a TRUE statement about the muscles of the abdominal wall?
The external abdominal oblique aponeurosis passes posterior to the rectus abdominis muscle
The internal abdominal oblique muscle takes origin, in part, from the medial 2/3 of the inguinal ligament
The fiber direction of the transversus abdominis muscle is parallel to the fiber direction of the innermost intercostal muscle
The rectus abdominis muscles are antagonists of the erector spinae muscles
Abdominal wall muscles are innervated exclusively by intercostal nerves
7 The inguinal canal:
Begins at the deep inguinal ring
Has the internal oblique forming part of its roof
Has the inguinal ligament forming its floor
Has the ilioinguinal nerve coursing through the superficial ring
All of the above
8 In the scrotum:
The pampiniform plexus of veins lies external to the internal spermatic fascia
Camper's fascia forms the cremaster muscle layer
The ductus deferens conveys sperm from the head of the testis to the epididymis
The sinus of the epididymis separates the testis from the body of the epididymis
None of the above
9. The vascular supply to the anterior abdominal wall arises from all of the following EXCEPT :
The superior epigastric artery
The 10th posterior intercostal artery
The lateral thoracic artery
The superficial epigastric artery
The musculophrenic artery
10. All of the following structures are palpable on the abdominal wall EXCEPT the:
Anterior superior iliac spine
Iliac crest
Pubic crest
Arcuate line
Pubic tubercle
11. A CT scan reveals that a loop of gut exits the abdominal cavity by passing medial to the inferior epigastric artery. This type of hernia would be called a:
Direct inguinal hernia
Indirect inguinal hernia
Congenital inguinal hernia
Femoral hernia
Lumbar hernia
12. In reference to the covering layers of the spermatic cord and testis:
The internal spermatic fascia is dense regular connective tissue
The external oblique muscle contributes the cremaster muscle
The tunica dartos contains large amounts of fat
The cremaster muscle is innervated by the genital branch of the genitofemoral nerve
Scarpa's fascia contributes the tunica vaginalis testis
13. Which of the following is a FALSE statement about the peritoneum and its specializations?
The peritoneum is an invaginated serous sac
The greater omentum connects the stomach to the liver
The lesser peritoneal sac communicates with the greater peritoneal sac through the epiploic foramen
The mesentery is two layers of peritoneum with connective tissue, fat and blood vessels sandwiched between
The spleen is suspended in the peritoneal cavity by the gastrosplenic and splenorenal ligaments
