Final answer:
The sagittal plane divides the body into right and left sides. It is also known as the anteroposterior (AP) plane. Other commonly used planes in anatomy include the frontal and transverse planes.
Step-by-step explanation:
The sagittal plane, also known as the anteroposterior (AP) plane, divides the body or an organ vertically into right and left sides. If the plane runs directly down the middle of the body, it is called the midsagittal or median plane. If it creates unequal right and left sides, it is called a parasagittal plane or less commonly a longitudinal section.
Other planes commonly used in anatomy include the frontal plane, which divides the body or an organ into anterior (front) and posterior (rear) portions, and the transverse plane, which divides the body or an organ horizontally into upper and lower portions.
Understanding these different planes helps anatomists and medical professionals study and describe the structure and function of the human body.
