35. Which of the following planes divides the body into left and right halves?
Answer: A
The sagittal plane divides the body into left and right halves.
The sagittal plane is the anatomical plane that divides the body into left and right sections. This plane runs vertically from the front to the back of the body.
A) Sagittal plane
This option is correct because the sagittal plane specifically separates the body into left and right halves. It is oriented vertically and is crucial in anatomical studies to describe the positioning of structures relative to each other.
B) Transverse plane
The transverse plane is incorrect as it divides the body into superior (upper) and inferior (lower) parts. It is oriented horizontally, not vertically, and thus does not separate the body into left and right halves.
C) Frontal plane
The frontal plane, also known as the coronal plane, divides the body into anterior (front) and posterior (back) sections. It does not serve the purpose of dividing the body into left and right halves, making this option incorrect.
D) Coronal plane
The coronal plane is synonymous with the frontal plane and also divides the body into anterior and posterior sections. Therefore, it does not fulfill the criteria of dividing the body into left and right halves, rendering this option incorrect.
Conclusion
The sagittal plane is the only option that accurately divides the body into left and right halves, while the other options describe different anatomical planes that do not achieve this division. Understanding these planes is fundamental in anatomy, as they help in identifying and describing the locations of various structures within the body.
