Which plane is responsible for dividing the trunk of the animal?

The transverse plane is responsible for dividing the trunk of the animal into cranial (head end) and caudal (tail end) sections. This segmentation is crucial in veterinary medicine as it allows for a clear understanding of the orientation of body structures during examinations, surgeries, and imaging. By using the transverse plane as a reference, veterinarians can more effectively locate and address health issues within different parts of the trunk, such as the thorax and abdomen.

The sagittal plane, while it divides the body into left and right sections, does not focus specifically on the trunk division. The median plane is a specific type of sagittal plane that creates equal left and right halves, which again does not pertain specifically to trunk division. The frontal plane, on the other hand, divides the body into dorsal (back) and ventral (belly) sections, which is not the same as the transverse plane's function of dividing the trunk into upper and lower parts.
