The part of the spinal column that is directly connected with or forms a part of the pelvis by articulation with the ilia and that in humans forms the dorsal wall of the pelvis and consists of five fused vertebrae diminishing in size to the apex at the lower end which bears the coccyx
The base support for the spine. This bone is made up of the S1 through S5 vertebrae, which are fused to form a triangular bone. The sacrum articulates with the L5 vertebra through the L5-S1 intervertebral disc superiorly. Inferiorly, it articulates with the ilium on either side.
a group of fused backbones located at the caudal end of the spine. They are triangular shaped and are located in the posterior portion of the pelvic ring. These bones are connected to the last vertebrae, the coccyx, and the hipbone on each side. The three bones of the pelvic bone are the ishium, the ilium and the pubis.
The sacrum consists of five vertebrae, which have fused together to form a single bone mass called the sacrum. The sacrum and pelvis (ilium) connect through the sacroiliac joints. The bottom of the spine, the coccygeal region, consists of four vertebrae, which, like the sacrum, have all fused together to form the coccyx or tailbone.
The large heavy bone at the base of the spine, which is made up of fused sacral vertebrae. The sacrum is located in the vertebral column, between the lumbar vertebrae and the coccyx. It is roughly triangular in shape and makes up the back wall of the pelvis. The female sacrum is wider and less curved than the male. See the entire definition of Sacrum
The lower portion of the spine which is below the low back and above the tail bone or the coccyx. The sacrum attaches to the pelvis. It contains some of the lowest spinal nerves. It is one of the bones most frequently fused by spinal surgeons.
A part of the spine that is also part of the pelvis. It articulates with the ilia at the sacroiliac joints and articulates with the lumbar spine at the lumbosacral joint. The sacrum consists of five fused vertebrae that have no intervertebral discs.
The sacrum is a large, triangular bone at the base of the spine and at the upper and back part of the pelvic cavity, where it is inserted like a wedge between the two hip bones. Its upper part connects with the last lumbar vertebra, and bottom part with the coccyx (tailbone).
