大转子 - Trochanter major

描述

The greater trochanter is a process on the lateral part of the proximal extremity of femur. His size is variable between species and it extends upper the head of femur in large animals.  It is the attachment for medial, accessory and deep gluteal muscles. 

In cows, there is a horizontal crest separating the greater trochanter form the body of the femur, for attachment of vastus lateralis.

In horses, the greater trochanter is divided into a cranial part (with a prominent crest (crest of the great trochanter; crista trochanterica lateralis) on the lateral aspect for the insertion of accessory gluteal muscle) and a caudal part. The trochanteric notch separates these the lateral and caudal parts of greater trochanter.
