The term "rear" refers to the back part of something, often used to describe the opposite of the front. In human anatomy, the rear typically refers to the buttocks, which are located at the posterior end of the body. This area plays a role in movement and posture, providing support when sitting and standing. In vehicles, the rear is the section opposite the front, often housing the trunk or tailgate. It is important for safety features, such as taillights and rearview cameras, which help drivers navigate and avoid obstacles while reversing.
