1. Terminology of Common Body Positions In order to facilitate the study and study of the position changes and structures of various parts of the human body, it is stipulated that the standard anatomical position of the human body is that the body is upright, the eyes are looking straight ahead, the heels are close together, the toes are forward, the upper limbs naturally hang down on both sides of the trunk, and the palms are forward. Based on the above postures, some terms of common human postures are determined.
Up-near the head is called up;
Down-near the soles of the feet is called down; ?
Anterior side-near the ventral side is called anterior side;
The back-near the back is called the back;
Medial-near the midline of the body is called medial;
Lateral-far away from the midline of the body is called lateral;
Proximal end-near the root of the limb is called proximal end;
Distal-far away from the annoying part of the body is called distal;
Ulnar side-the inside of forearm is called ulnar side;
Radial side-the outside of forearm is called radial side;
The tibial side-the inside of the calf is called the tibial side;
The fibula side-the outside of the calf is called the fibula side;
Shallow-close to the skin surface is called shallow;
Deep-away from the skin surface is called deep.
2. A part of the human body
(1) sagittal plane? The section perpendicular to the horizontal plane along the front and back diameter of the human body is called sagittal plane. When the sagittal plane is in the middle and divides the human body into left and right halves, this section is called the median sagittal plane.
(2) Horizontal plane (cross section)? Parallel to the ground, the section that divides the human body into upper and lower parts is called the horizontal plane.
(3) Frontal surface (coronal surface)? The cross section made by dividing the human body into two parts along the left and right diameter of the human body is called the frontal plane.
