An analysis of
the literature has allowed for a redefinition of the anatomy of the
ilio-coccygeus muscle (ICM) its insertions and its trajectory, the direction of
its fibers
and its relation to the base of the bladder.
Static MRI
studies have revealed its V-shaped appearance, while dynamic MRI has been used
to visualize its concave contraction into a dome-shape that provides support to
the levator plate, raising the base of the bladder.
Histological
studies have shown that the percentage of type I muscle fibers is 66% to 69%, which
is comparable to the type I fiber content of the pubovisceral muscle (PVM),
thus reflecting both its postural role as well as functions based on frequent
voluntary contractions.
