The inferior articular process or facet of the vertebra above.
That is called as coccyx. There are many small vertebrae in this small bone. Some have longer coccyx, making them more like monkey.
The ala of the sacrum are paired extensions that help support the weight of the body and provide attachment points for ligaments and muscles. They articulate with the ilium at the sacroiliac joint, forming a stable connection between the axial skeleton and the pelvis. The ala also contribute to the overall strength and stability of the sacrum, especially during weight-bearing activities.
The Sacral Canal runs throughout the greater part of the Sacral bone, The four Posterior Sacral Foramina are lateral to the articular processes of the Sacrum and are smaller in size and less regular in form than the anterior.
sacrum and coccyx
No
yes
No. There are no intervertebral discs in the Sacrum. The Sacrum is a fusion between 5 vertebrae and this the same with the Coccyx (fusion of 3). The final intervertebral disc is between L5 and the superior surface of the Sacrum.
That is called as coccyx. There are many small vertebrae in this small bone. Some have longer coccyx, making them more like monkey.
The joint between the sacrum and the hip bone is the sacroiliac joint. It is also known as the SI joint. They form the articular surfaces.
The illium, ischium, and pubic are the 3 pelvic bones that articulate with the pelvic girdle

The vertebrae consist of the vertebral body, spinous process, transverse process, and articular processes. There are 33 vertebrae in total, including 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 sacral vertebrae (fused into the sacrum), and 4 coccygeal vertebrae (fused into the coccyx).
It articulates with each vertebra. Plus the occipital bone of the skull and the 12 pairs of ribs.
The Sacral Canal runs throughout the greater part of the Sacral bone, The four Posterior Sacral Foramina are lateral to the articular processes of the Sacrum and are smaller in size and less regular in form than the anterior.
The median sacral crest on the sacrum is a bony ridge formed by fusion of sacral vertebrae, indicating where the individual vertebrae once were. In contrast, the median sacral crest on lumbar vertebrae does not exist, as lumbar vertebrae do not fuse in the same way as sacral vertebrae.
