Pelvis and Hip Bone - Parts, Landmarks and Articulation - Anatomy

Learn the comprehensive anatomy of the pelvis and hip bone through detailed examination of their structural components, anatomical landmarks, and articulations. Explore the pelvis as a ring-like bony structure connecting the spine to lower limbs, understanding its division into greater and lesser pelvis regions and key measurements including transverse, oblique, and anatomical conjugate diameters. Master the three components of the hip bone starting with the ilium and its features including the iliac crest, anterior and posterior iliac spines, iliac fossa, gluteal lines, and auricular surface for sacroiliac articulation. Study the pubis with its tubercle, crest, symphysial surface, and superior and inferior rami that help form the obturator foramen. Examine the ischium including the ischial tuberosity, spine, and greater and lesser sciatic notches, plus understand how the ischial ramus fuses with the inferior pubic ramus. Analyze the acetabulum's structure including its margin, notch, lunate surface, and central fossa that forms the hip socket. Conclude by reviewing the major pelvic articulations including the sacroiliac joint and pubic symphysis, along with their supporting ligamentous structures such as the sacrotuberous, sacrospinous, and various pubic ligaments that provide stability to this crucial anatomical region.
