XROMM animation of costal cartilages 1 & 2
Rib kinematics & intercostal muscle strain during breathing in Iguana iguana
XROMM animation of costal cartilages 1 and 2 with attachment points of the parasternal internal intercostal (pII) muscle fascicles mapped onto the models. The change in length of one of the pII fascicles over time is shown. The pII lengthens during exhalation and shortens during inhalation.
