Multiple Choice
Which of the following is the superior transverse plane of the abdominal region?
A
Transtubercular plane
B
Subcostal plane
C
Interspinous plane
D
Transpyloric plane
Verified step by step guidance
1
Understand the concept of transverse planes in the abdominal region. These planes are imaginary horizontal lines used to divide the abdomen into regions for anatomical study and clinical reference.
Review the four transverse planes mentioned in the problem: Transtubercular plane, Subcostal plane, Interspinous plane, and Transpyloric plane. Each plane is located at a specific anatomical landmark.
Learn the anatomical location of the Transpyloric plane. It is positioned at the level of the L1 vertebra and passes through the pylorus of the stomach, making it the superior transverse plane compared to the others.
Compare the anatomical positions of the other planes: The Subcostal plane is located at the level of the 10th rib, the Transtubercular plane is at the level of the iliac tubercles (L5 vertebra), and the Interspinous plane is at the level of the anterior superior iliac spines. These are all inferior to the Transpyloric plane.
Conclude that the Transpyloric plane is the correct answer because it is the superior transverse plane in the abdominal region, located higher than the other planes mentioned.
