For bipedal (two legged) humans, some of the anatomical terms are applied differently, and they are always referenced to an individual standing in what is known as the standard anatomical position. Thus, for such an individual, the sagittal (median) plane divides the body or an organ into left and right sides while a transverse (horizontal) plane divides the body or organ into superior (upper) and inferior (lower) portions, and a frontal (coronal) plane divides the body or organ into anterior and posterior sides. The other terms remain the same. Thus, in humans the nose is superior to the mouth, and the sternum (breast bone) bone is anterior to the vertebral column. |
