Document Summary

Stems from the way a dead body lies on a table. Standing upright: the reference position for the human body as agreed by anatomists, biomechanics, doctors, etc, arms down, palms forward, knees together, toes forward. For segment motion, the anatomical position may not be convenient for analysis. Principal planes: a plane is an imaginary, perfectly flat surface, we can image 3 passing through the human body, each at right angles to each other (i. e. mutually orthogonal) Sagittal plane: divides the body into left and right. Frontal plane: divides the body into front and back: transverse plane: divides the body into top and bottom. Principle axes: each plane has one axis, which is the line that is at right angles to the plane. This is known as the plane"s normal vector and mathematically defines the plane uniquely: the principal axes pair with the principal planes, transverse plane- internal- external rotation axis (ie) (for appendicular skeleton/ longitudinal axis.
