The knee flexes (bends) normally to a maximum of 135 degrees and extends (straightens) to 0 degrees. Thus, ligaments and tendons are another example of the structure-function concept and the mechanically mediated adaptation concept that permeate this biomechanics course. Ligaments are vulnerable to injury from stretching, which can cause them to tear. 3. cordlike remnants of fetal tubular structures that are nonfunctional after birth. It is flat, and triangular in form; narrower in the middle than at the ends.
