Short bundles of skeletal muscle fibre
The
interspinales
are short
muscle fascicles
, found in pairs between the spinous processes of the contiguous
vertebrae
, one on either side of the
interspinal ligament
.
- In the
cervical region
, the
cervical interspinales
are most distinct, and consist of six pairs, the first being situated between the
axis
and third vertebra, and the last between the seventh cervical and the first thoracic. They are small narrow bundles, attached, above and below, to the apices of the spinous processes.
- In the
thoracic region
, the
thoracic interspinales
are found between the first and second vertebrae, and sometimes between the second and third, and between the eleventh and twelfth.
- In the
lumbar region
, there are four pairs of
lumbar interspinales
in the intervals between the five lumbar vertebrae. There is also occasionally one between the last thoracic and first lumbar, and one between the fifth lumbar and the
sacrum
.
