Which of the following is the inferior transverse plane of the abdominal region?
A
Transtubercular plane
B
Transpyloric plane
C
Midclavicular plane
D
Subcostal plane
Verified step by step guidance1
Understand the concept of transverse planes in the abdominal region. These are imaginary lines used to divide the body into sections for anatomical study.
Identify the location of each plane mentioned in the options: Transtubercular, Transpyloric, Midclavicular, and Subcostal.
The Transtubercular plane is located at the level of the iliac tubercles, which is generally lower than the other planes mentioned.
The Transpyloric plane is located at the level of the pylorus of the stomach, which is higher than the Transtubercular plane.
The Subcostal plane is located at the level of the lower border of the costal margin, and the Midclavicular plane is a vertical line, not a transverse plane. Therefore, the Transtubercular plane is the inferior transverse plane among the options.
