The most lateral projection of the proximal epiphysis of the femur is the:


a. lesser trochanter
b. gluteal tuberosity
c.greater trochanter
d.femoral neck.

Verified step by step guidance

1. Identify the anatomical location of the proximal epiphysis of the femur, which is the end of the femur closest to the hip joint.
2. Understand that 'lateral' refers to the side of the body or a structure that is farther from the midline.
3. Review the anatomical features of the proximal femur: the greater trochanter, lesser trochanter, gluteal tuberosity, and femoral neck.
4. Recognize that the greater trochanter is a large, prominent projection on the lateral side of the proximal femur.
5. Conclude that the most lateral projection of the proximal epiphysis of the femur is the greater trochanter.

Key Concepts

Proximal Epiphysis of the Femur

The proximal epiphysis of the femur is the upper end of the femur bone, which includes important structures for muscle attachment and joint articulation. It consists of the femoral head, neck, and greater and lesser trochanters, which are critical for understanding the anatomy and function of the hip joint.

Trochanters

Trochanters are large, bony prominences on the femur that serve as attachment points for muscles. The greater trochanter is located laterally and is more prominent, while the lesser trochanter is smaller and located medially. Understanding their locations and functions is essential for identifying the correct answer to the question.

Lateral Projection

A lateral projection refers to a structure that extends outward from the midline of the body. In the context of the femur, identifying the most lateral projection involves recognizing which anatomical feature is furthest from the center of the body, which is crucial for determining the correct answer among the options provided.
