♦ Muscles,
♦ Ligaments, and
♦ Facet joints.
16 . 1 Muscles
Pairs of very strong, short muscles lie either side of the vertebral column and are attached to the
spines and transverse processes of each vertebra. These muscles may be called collectively the

nerve roots. They are very prone to minor tears from over-exertion in manual lifting and this
accounts for many episodes of acute backache.
