Question

A greater trochanter is found in
(A) Humerus
(B) Ulna
(C) Femur
(D) Radius

Answer 1

Hint: The trochanter is the small rounded projections over the bones of the femur at the point near the hip bones. They help in the attachment of the bones and the muscles. They are two types as greater and the lesser. These knobs are greater at the outside of the bones and lesser at the inside of the bones.

Complete answer:
Femur is the larger thigh bone present in the human body. The trochanter of this bone is located at the proximal and the lateral femur part and is irregular in shape. It is also called as the major trochanter or the outer trochanter .The femur trochanter joins the muscles of the hip and the thigh for the proper coordination. The muscles that are attached to the greater trochanter are gluteus medius and minimus, piriformis, obturator externus and the internus and the gemelli muscles. Hence the greater trochanter is located in the femur.

Additional information: Similar to the greater trochanter, there is the lesser trochanter in the body of the mammals. It is also called the minor trochanter or the inner trochanter. This gives attachment for the muscle of the psoas major and the iliacus.

Hence the correct answer is OPTION(C)

Note: This tubercle of the trochanter is present in the human and the most of the mammals. This helps most of the muscles of the body to coordinate and function. The greater trochanter is located backward of the femur bone and the minor trochanter is at the inner side of the femur.
