The motion around the sagittal axis on the coronal plane is adduction and abduction. Sagittal axis is an axis parallel to the ground and perpendicular to the coronal plane, and it is one of the three basic axes perpendicular to the human body. It is equivalent to the Z axis in the mathematical triaxial coordinate system. Axis is often used to indicate the axis along which the displacement trajectory of bones moves when joints move.

Coronal axis (frontal axis): the axis whose left-right direction is parallel to the ground and perpendicular to the sagittal plane. Vertical axis: the axis perpendicular to the vertical direction of the dry floor. Sagittal plane is a section taken along the sagittal axis. It is a longitudinal section that divides the human body into left and right parts. If this section just passes through the midline of the human body, it is called the median sagittal plane.

Longitudinal axis: it is the axis perpendicular to the ground from head to tail. Sagittal plane refers to the longitudinal section that divides the human body into left and right parts along the front and back direction, and is perpendicular to the ground plane. The sagittal plane passing through the middle of the human body is the median sagittal plane, which divides the human body into two equal parts.

Coronal plane refers to the longitudinal section that divides the human body into left and right parts, which is perpendicular to the sagittal plane and the horizontal plane. The horizontal plane, also known as the horizontal plane, is a plane parallel to the ground plane, which divides the human body into upper and lower parts. The plane is perpendicular to the coronal and sagittal planes.
