The deep musculature of the pelvic and thigh regions forms the foundation of the lower body's strength and mobility. This article explores the deep pelvic and thigh muscles of the right leg, presented in an anterior view, offering a detailed look at their anatomical structure and functional roles. These muscles, originating from the pelvic girdle and inserting into the femur or knee joint, are vital for movements such as thigh flexion, lower leg extension, and a combination of adduction, abduction, and rotation. Through the labeled diagram, readers can develop a thorough understanding of these muscles' contributions to leg function and their relevance in clinical settings.

The pelvis, a robust bony structure, relies on a complex network of ligaments to maintain stability, facilitate movement, and support the body’s weight during daily activities. Key ligaments such as the posterior sacroiliac ligament, sacrospinous ligament, and sacrotuberous ligament play critical roles in reinforcing the sacroiliac joint and forming the greater and lesser sciatic foramina, which are essential for neurovascular passage. This article provides an in-depth exploration of the ligaments of the pelvis, their anatomical features, and their significance in human biomechanics.

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.
