coccyx
The inferior end of the sacrum is composed of the coccyx, which is a small triangular bone formed by the fusion of 3-5 vertebrae. The coccyx serves as an attachment site for ligaments and muscles and helps support the pelvis when sitting.
The sacrum and coccyx lie inferior to the lumbar vertebrae in the vertebral column.
The end of the sacrum is your trail bone. I have fusions there.
sacrum and coccyx
The sacrum is composed of five fused vertebrae, which are typically designated as S1 to S5. These vertebrae fuse together during adolescence to form a single triangular-shaped bone that connects the spine to the pelvis. The sacrum plays a crucial role in supporting the weight of the upper body and providing stability to the pelvis.
The sacrum is formed by the fusion of five vertebrae.
Lumbar
The sacrum is the composite bone that articulates with the hip bone laterally at the sacroiliac joint. The sacrum is a large, triangular bone at the base of the spine formed from the fusion of several vertebrae.
the sacrum-bg
The vertebral column consists of five main parts, listed from superior to inferior as follows: the cervical vertebrae (7 vertebrae in the neck), the thoracic vertebrae (12 vertebrae in the upper back), the lumbar vertebrae (5 vertebrae in the lower back), the sacrum (5 fused vertebrae forming the posterior part of the pelvis), and the coccyx (4 fused vertebrae forming the tailbone). Each region has distinct characteristics and functions that contribute to the overall structure and flexibility of the spine.
