Puusapiirkond

Puusapiirkond refers to the anatomical region of the human body encompassing the hips. This area is crucial for mobility, weight bearing, and connecting the torso to the lower limbs. It comprises several key structures, including the pelvic girdle, the hip joint, and the muscles surrounding these bones. The pelvic girdle is formed by the two hip bones (os coxae) which articulate with the sacrum at the sacroiliac joints. Each hip bone consists of three fused bones: the ilium, ischium, and pubis. The hip joint itself is a ball-and-socket joint formed by the head of the femur (thigh bone) fitting into the acetabulum, a socket on the hip bone. This structure allows for a wide range of motion, including flexion, extension, abduction, adduction, and rotation. Major muscles in the puusapiirkond include the gluteal muscles, hip flexors, and adductors, all essential for walking, running, and maintaining balance. Due to its weight-bearing function and extensive use, the puusapiirkond is susceptible to various injuries and conditions, such as arthritis, fractures, and muscle strains.
