trochanter

One of two major bony processes, the greater and lesser trochanters, on the upper part of the FEMUR. Muscle tendons are attached to the trochanters.

trochanter

  1. (in insects) the second segment from the base of the leg.
  2. (in vertebrates) one of several large processes near the head of the femur to which muscles are attached.

trochanter

prominence near end of a long bone; develops from independent centre of ossification

trochanter

one of three tuberosities on the femur, at the upper end of its lateral surface (greater trochanter), towards the upper end on its medial surface (lesser trochanter) and more distally on the lateral surface (third trochanter). The third trochanter is prominent in horses and rabbits.
