Aponeuroses (plural of aponeurosis: , "away" or "of", and , "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.

Anterior abdominal aponeuroses

The anterior 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.

Posterior lumbar aponeuroses

The Posterior 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.
