Final answer:
The midsagittal plane divides the body into two equal right and left halves. In contrast, the frontal plane divides the body into front and back, and the transverse plane divides it into upper and lower sections.
Step-by-step explanation:
The plane that divides the body into two equal right and left halves is known as the midsagittal plane. This vertical plane runs directly down the middle of the body, creating symmetrical halves. In contrast, the frontal plane, also referred to as a coronal plane, divides the body into anterior (front) and posterior (rear) portions. The transverse plane, also called a horizontal plane, divides the body into upper and lower sections, producing what are known as cross sections. It is important to note that a parasagittal plane would divide the body into unequal right and left sides, and is not the same as the midsagittal plane.
