Fig. 3. (A) Changes in length of the Mm. appendicocostales muscle with rib angle, ${theta}$ , for various relative values of uncinate length, Q, and distance of posterior attachment, P. (B) Changes in mechanical advantage of the Mm. appendicocostales muscle with rib angle, ${theta}$ , for various relative values of uncinate length, Q, and distance of posterior attachment, P. It can be seen that mechanical advantage increases with ${theta}$ , and with higher values of Q.
