Parapatellar fibrocartilage
60
Why does the ox have a harder time with parturition?
The ischium of the ossa coxarum slants dorsally and the initial part of the pelvic canal is narrowed

The groove located between the medial and lateral ridge of the trochlea of the femur
62
What is the purpose of the proximal aspect of the trochlear tubercle of the femur in the equine?
