How Your Spine Works
Your spine consists of 24 vertebrae plus
your sacrum and coccyx. The first of your seven cervical (neck)
vertebrae (C1), called the "atlas," holds the globe of the
skull. Your second, (C2) the "axis",
permits head turning and tilting. Cervical vertebrae C3 - C7 continue
through the neck.
Your 12 thoracic (mid-back) vertebrae (T1
- T12) all connect to the ribs in the back, and all but two (T11 and
T12, which "float") join the sternum (breastbone) in front.Your five lumbar (lower back) vertebrae
are the biggest, thickest, and most massive vertebrae. These
support the weight of your entire spine, which is why so many spinal
problems are in the lower back (lumbar) area.
Your sacrum is made up of five fused
vertebrae. The sacrum and the hips on either side make up your
pelvis. Your coccyx, four fused vertebrae, is
what's left of your tailbone.
