Sacrum and Coccyx Anatomy Inferior to the fifth lumbar vertebra (L5) are the sacrum and coccyx bones. The large, triangular-shaped sacrum (os sacrum) is composed of five vertebrae (S1 - S5) that fuse during early adulthood (18 - 30 years). The smaller coccyx (os coccygis) articulates with S5 and is also known as the tailbone. It consists of three to five vertebrae (C1 - C5) that are also usually fused.

Spinal anatomy Cervical spine (C1 to C7) — this is the upper or neck area of the spine, which is made up of the seven vertebrae at the top of the spine, which help support the head. Thoracic spine (T1 to T12) — the 12 vertebrae in the central section, to which the ribs are attached. Lumbar spine (L1 to L5) — the five vertebrae toward the lower back, which support much of the body’s weight. Sacrum (S1 to S5) — the five fused vertebrae located between the pelvic bones.

Anatomy of the Human Spine Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused. The vertebrae in each region have unique features that help them perform their main functions. Cervical (neck) - the main function of the cervical spine is to support the weight of the head (about 10 pounds).

Chapter 39: The vertebral column Chapter 39: The vertebral column. Vertebral column in general. The vertebral column usually consists of 33 vertebrae: 24 presacral vertebrae (7 cervical, 12 thoracic, and 5 lumbar) followed by the sacrum (5 fused sacral vertebrae) and the coccyx (4 frequently fused coccygeal vertebrae). The 24 presacral vertebrae allow movement and hence render the vertebral column flexible. Stability is provided by ligaments, muscles, and the form of the bones. The abbreviations C., T., L., S., and Co. are used for the regions, and these are sometimes followed by V. for vertebra or N. for nerve.
