Document Summary

Anatomical position: anatomical position is the reference position for the human body as agreed by anatomists, biomechanics, doctors, etc. Shown standing upright, arms down, palms forward, knees together, toes forward. Like a dead body lying on a slab (old time grave robbing by anatomists for research) For segment motion, the anatomical position may not be convenient for your analysis. So for each joint or body position, you decide what the neutral position is: this segment or joint position where the angle is defined as zero degrees, the choice is up to you. Principal planes: a plane is an imaginary, perfectly flat surface, we can imagine 3 passing through the human body, each at right angles to each other (i. e. mutually orthogonal) Frontal plane: transverse plane, axial skeleton is always the same. For appendicular skeleton the planes move with the anatomy. Sagittal plane - mediolateral axis (ml) (yes motion) Frontal plane - anterior posterior axis (ap) (side to side motion)
