The human hip bone, or os coxae, is a complex, irregularly shaped structure formed by the fusion of three primary bones: the ilium, ischium, and pubis. This lateral view of a cadaveric specimen highlights the essential landmarks necessary for understanding pelvic biomechanics and orthopedic surgery. The hip bone serves as the mechanical link between the axial skeleton and the lower limbs, facilitating weight transfer and locomotion.

The appearance of the linea nigra, a distinct dark line running down the center of the abdomen, is a common and fascinating physiological change observed during pregnancy. This image clearly depicts the linea nigra on an abdomen at 22 weeks gestation, extending vertically from the umbilicus towards the pubis. While it may be a cause for curiosity or concern for some, it is a benign dermatological manifestation of the profound hormonal shifts occurring during pregnancy. This article will explore the characteristics, causes, and temporary nature of this unique pregnancy marker.

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.
