Thickness is defined as the area between the aponeuroses of the muscle. The palmar aponeuroses occur on the palms of the hands. The anterior abdominal aponeuroses are located just superficial to the rectus abdominis muscle. The plantar aponeuroses occur on the plantar aspect of the foot. The short intrinsic extensors and the plantar and dorsal interossei radiates into these aponeuroses. The extensor hoods are aponeuroses at the back of the fingers. When dissected, aponeuroses are papery and peel off by sections.
