The perforate acetabulum is a cup-shaped opening on each side of the pelvic girdle formed where the ischium, ilium, and pubis all meet, and into which the head of the femur inserts. [ 8 ] [ 9 ] The orientation and position of the acetabulum is one of the main morphological traits that caused dinosaurs to walk in an upright posture with their ...
The dog's footpad is a fatty tissue locomotive-supporting organ, present at the bottom of the four legs, consisting of digital pads, a metacarpal pad, and a carpal pad, with dewclaw near the footpad. [26] When a dog's footpad is exposed to the cold, heat loss is prevented by an adaptation of the blood system that recirculates heat back into the ...
The acetabular fossa is the non-articular depressed region at the centre of the floor of the acetabulum. It is surrounded by the articular lunate surface. [1]: 1368 [2] The floor of the fossa is formed mostly by the ischium; [2] it is rough [1]: 1354 and thin (often to the point of transparency).
The acetabular labrum (glenoidal labrum of the hip joint or cotyloid ligament in older texts) is a fibrocartilaginous ring [1] [2] [3] which surrounds the circumference of the acetabulum of the hip, deepening the acetabulum. The labrum is attached onto the bony rim and transverse acetabular ligament. It is triangular in cross-section (with the ...
The acetabular notch is a deep [citation needed] notch in the inferior portion of the rim of the acetabulum. [1]: 1354 It is bridged by the transverse acetabular ligament, converting it into a foramen (through which nerves and vessels (including the acetabular notch of obturator artery [1]: 1250 ) pass into the hip joint cavity).
Tests of animal bones found nearby suggest that the climate was harsh — comparable to modern-day Siberia. That means humans were having success in an extreme climate some 45,000 years ago.
The lunate surface of acetabulum is the articular surface of the acetabulum which makes contact with the femoral head as part of the hip joint. It forms an incomplete ring that is deficient inferiorly - opposite the acetabular notch .
The cave was excavated in the 1930s, with bones and stone artifacts found, before World War Two interrupted the work. Technology at the time could not identify the bones. Researchers re-excavated ...
