Aponeurosis

Aponeuroses (απο, "away" or "of", and νευρον, "sinew") are membranes separating muscles from each other. 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.

The palmar aponeuroses occur on the palms of the hands, and are referred to in the Patrick O'Brian Aubrey–Maturin series of books.
