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 sections for anatomical study and clinical reference.
Learn the definitions of the given planes:
- Transpyloric plane: Located at the level of the L1 vertebra, it passes through the pylorus of the stomach.
- Subcostal plane: Located at the level of the L3 vertebra, it passes just below the costal margin.
- Transtubercular plane: Located at the level of the L5 vertebra, it passes through the iliac tubercles.
- Interspinous plane: Located at the level of the anterior superior iliac spines.
Compare the relative positions of these planes. The term 'superior' refers to a higher position in the body. Among the listed planes, the Transpyloric plane is the most superior as it is located at the L1 vertebra, higher than the others.
Recall that the Transpyloric plane is clinically significant because it passes through important structures such as the pylorus of the stomach, the duodenojejunal junction, and the neck of the pancreas.
Conclude that the superior transverse plane of the abdominal region among the options provided is the Transpyloric plane, based on its anatomical location and clinical relevance.
