lower limb anatomy

The Q-angle, or quadriceps angle, is a critical measurement in human anatomy that quantifies the lateral deviation of the femur from the vertical line of the tibia, reflecting the alignment of the lower limb. Adult females typically exhibit a larger Q-angle due to their wider pelvis, which influences the biomechanics of the knee and hip joints. This article delves into the anatomical structure of the Q-angle, its physical implications, and its functional and clinical significance in the human body.

The femur and patella are integral components of the lower limb, playing essential roles in movement, stability, and weight-bearing in the human body. The femur, the longest and strongest bone, connects the hip bone to the tibia, while the patella, a small sesamoid bone, enhances knee joint mechanics by protecting the joint and improving leverage during movement. This article provides a comprehensive exploration of their anatomical structure, physical characteristics, and functional significance.
