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 hip bone, a critical component of the human skeletal system, plays a vital role in supporting the body's weight, facilitating movement, and protecting internal organs. Comprised of three distinct regions—the ilium, ischium, and pubis—this bone forms the foundation of the pelvis and connects the lower limbs to the axial skeleton. This article delves into the detailed anatomical structure of the hip bone, exploring its labeled parts, physical characteristics, and functional significance in the human body.
