XROMM kinematics of ventilation in wild turkeys (Meleagris gallopavo)
Journal of Experimental Biology
The avian ribcage is derived relative to other amniotes, and is hypothesised to be constrained in its movements during ventilation. The double-headed ribs form two articulations with the vertebrae, and are thought to rotate about a strict anatomical axis. However, this costovertebral joint constraint has not been demonstrated empirically and was not found in other taxa with double-headed ribs (i.e. crocodilians). Here, we used X-ray reconstruction of moving morphology (XROMM) to quantify ribdoi:10.1242/jeb.209783 pmid:31704902 fatcat:v3jhvug7xbfrjd453mcdpayge4
