| 释义 | sacrum noun[ C ] anatomy specializeduk /ˈseɪ.krəm/ us /ˈsæk.rəm/pluralsacra or sacrums a triangle-shaped bone at the base of the lower back above the coccyx(= a small bone at the base of the spine)骶骨 Bone structures acetabular acetabulum acromial acromioclavicular acromion foramen magnum frontal bone glenoid gnathic gynecoid osteology osteophyte osteotomy parietal parietal bone TMJ trapezoidal triquetrum true rib tubercle Examples of sacrumsacrum The posterior triangle has its apex at the tip of the sacrum. What we are talking about is the possibility of creating a secular sacrum in the theatre. The posterior wall of the pelvis is the sacrum, while the lateral walls are formed by the ischial bones, sacrosciatic notches and the pelvic ligaments. There was, however, no difference in the correlation of uptake of oxygen, between the vertically oriented monitors placed on the sacrum and iliac crest. Our experience is that the monitor is more comfortable when placed on the iliac crest, since when attached to sacrum, it may cause irritation, especially when seated. Soft tissue landmarks such as tumour and pelvis structures such as anterior sacrum and anterior ischial tuberosity were the exception with overall mean ratings of 'not clear' or 'not visible'. The monitors measuring in vertical axis placed on the sacrum and horizontal axis on the iliac crest showed variation between 25-50% for the two protocols varying for speed. To the side are two curved bones, which join the sacrum at the back and curve forward and are jointed at the front. From the Hansard archive Example from the Hansard archive.
