How are the Sacrum and Coccyx different from the other vertebrae? The sacrum consists of 5 fused sacral vertebrae and the coccyx consists of 4 fused coccygeal vertebrae. They are different because the are not moveable.
In tetrapod anatomy, the sacrum (/ËsaekrÉm/ ËsÃ¦krÉm /or/ ; ËseÉªkrÉm: plural sacra or; Sacrums latin os) sacrum is a, large triangular bone at the base of the spine and at the, upper back part of the pelvic, cavity where it is inserted like a wedge between the two hip. boneshe floor of the groove is formed by the united laminae of the corresponding vertebrae. The laminae of the fifth sacral vertebra, and sometimes those of the fourth, do not meet at the back, resulting in a fissure known as the sacral hiatus in the posterior wall of the sacral canal.
