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
histologicallysimilar to tendons, but are very sparingly supplied with blood vesselsand nerves. When dissected, aponeuroses are papery, and peel off by sections. The primary regions with thick aponeurosis is in the ventral abdominalregion, the dorsal lumbarregion, and in the palmarregion.
Ventral abdominal aponeuroses
ventral abdominal aponeurosesare 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
dorsal lumbar aponeurosesare situated just on top of the epaxial muscles of the thorax, which are multifidus spinaeand Sacrospinalis.
palmar aponeurosesoccur on the palms of the hands.
The aponeurosis (or
galea aponeurotica) is a tough layer of dense fibrous tissue which runs from the frontalis muscleanteriorly to the occipitalisposteriorly.
