Study Notes
Pelvic Limb Structure
- The pelvic limb is divided into four segments: pelvic girdle, thigh, leg, and pes.
Pelvic Girdle
- Formed by two symmetrical hip bones (os coxae) that connect at the symphysis pelvis ventrally and are firmly attached to the sacrum dorsally.
- Together with the sacrum and coccygeal vertebrae, they create the bony pelvis.
Os Coxae Composition
- Composed of three flat bones: ilium, ischium, and pubis, which converge at the acetabulum.
- The acetabulum is a significant cavity where the femur's head articulates.
Ilium Details
- The ilium forms the dorsocranial portion of the hip bone and extends obliquely from the acetabulum to the sacrum.
- It comprises a cranial expanded wing and a columnar body that contributes to the acetabulum.
- Coxal tuberosity is a notable landmark in domestic mammals, located at the lateral angle of the hip.
Sacral Tuber Characteristics
- The mediodorsal angle of the ilial wing is thickened to form the sacral tuber.
- In carnivores and cattle, the sacral tuber typically features two eminences.
Iliac Crest and Surface Features
- Iliac crest connects coxal tuberosity and sacral tuber; its shape varies across species.
- It is convex and thick in carnivores and pigs, while thin and concave in larger animals.
- The lateral surface of the ilium features gluteal lines, indicating muscle attachment areas.
