Aponeuroses (plural of
aponeurosis: απο, "away" or "of", and νευρον, "sinew") are layers of flat broad tendons. They have a shiny, whitish-silvery color, and are
histologically similar to
tendons, but are very sparingly supplied with
blood vessels and
nerves. When dissected, aponeuroses are papery, and peel off by sections. The primary regions with thick aponeurosis is in the
ventral abdominal region, the
dorsal lumbar region, and in the
palmar region.
Ventral abdominal aponeuroses
The
ventral abdominal aponeuroses are located just on top of the
rectus abdominis muscle. It has for its borders the
external oblique,
pectoralis muscles, and the
latissimus dorsi.
Dorsal lumbar aponeuroses
The
dorsal lumbar aponeuroses are situated just on top of the epaxial muscles of the thorax, which are
multifidus spinae and
Sacrospinalis.
Palmar aponeuroses
The
palmar aponeuroses occur on the palms of the hands.
Scalp aponeuroses
The aponeurosis (or
galea aponeurotica) is a tough layer of dense fibrous tissue which runs from the
frontalis muscle anteriorly to the
occipitalis posteriorly.
