Sagittal plane refers to the longitudinal section that divides the human body into two parts, the front and back direction and the left and right, which 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.

2, horizontal section to see the anatomical direction:

Horizontal plane: also called transverse plane, it is a plane that divides the human body into upper and lower parts parallel to the ground plane and perpendicular to the coronal plane and sagittal plane.

3, coronal section to see the anatomical position before and after:

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.

Extended data

1, standard anatomical posture:

The standard anatomical posture of the human body means that the body is upright, facing forward, eyes looking straight ahead, feet together, toes forward, upper limbs hanging on both sides of the trunk, palms forward. When describing any structure of human body, standard posture should be applied. Even if the observed object, specimen or model is in a different position or just a part of the body, it should be described according to the standard posture of the human body.

2. Axis in human anatomy

Vertical axis: the axis from head to tail and perpendicular to the ground plane.

Sagittal axis: refers to the axis that intersects the longitudinal axis at right angles from front to back.

Coronal axis or frontal axis: an axis parallel to the horizontal direction and perpendicular to the first two axes.
