The bone below the lumbar area of the spine that is made up of five fused sacral vertebrae.
The base of the spine formed by the fusion of fine vertebrae and located above the coccyx.
The large, triangular bone between the two hip bones at the back of the pelvis, formed by the fusion of five sacral vertebrae. Its base connects with the last lumbar vertebra, its apex with the coccyx.
A group of five fused vertebrae that are not individually numbered, except for the first sacral vertebra (SI); it joins with the hip bones to form the most posterior part of the pelvis.
A triangular bone in the lower spine. The sacrum lies just above the last bone of the spine, the coccyx or tail- bone, and below the lumbar spine. The sacrum joins with the hip bones at the sacroiliac joints to form the rear of the pelvis.
The triangular bone situated dorsal and caudal from the two ilia between the fifth lumbar vertebra and the coccyx. It is formed of five united vertebrae and is wedged between the two innominate bones, its articulations forming the sacroiliac joints. It is the base of the vertebral column and, with the coccyx, forms the posterior boundary of the true pelvis. The male sacrum is narrower and more curved than the female sacrum.
Triangular-shaped bone located at the base oft he spine and attached to the pelvis.
In the realm of human anatomy, there exists a triangular-shaped bone situated between the fifth lumbar vertebra and the coccyx. This bone, known as the sacrum, comprises the fusion of five vertebrae into a single structure. Notably, the sacrum forms connections on each side with the bones of the pelvis, further contributing to the structural integrity and functionality of the pelvic region. Understanding the role and composition of the sacrum aids in comprehending the complex interactions within the skeletal system and its impact on overall bodily function.
The sizeable triangular bone situated in the lower portion of the spine is known as the sacrum. Positioned at the center of the back of the pelvis, it features a wide upper section that connects with the fifth lumbar vertebra, the lowest in the spine, and a narrower lower part that links with the coccyx. On each side, the sacroiliac joints connect it to the ilium, or hip bone. Conditions impacting the sacrum encompass sacralgia, spondylolisthesis, and sacralization.
A curved, triangular bone formed by the fusion of five vertebrae, located between the lowermost lumbar vertebra above it, the coccyx below, and the innominate bones on either side. It constitutes the posterior wall of the pelvis and was referred to by ancient Romans as the “os sacrum,” meaning the sacred bone.
