Anterior abdominal aponeuroses The anterior abdominal aponeuroses are located just superficial to 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 and plantar aponeuroses and extensor hood The
palmar aponeuroses occur on the palms of the hands. The
extensor hoods are aponeuroses at the back of the fingers. The
plantar aponeuroses occur on the plantar aspect of the foot. They extend from the
calcaneal tuberosity then diverge to connect to the bones, ligaments and the dermis of the skin around the distal part of the metatarsal bones.
Anterior and posterior intercostal membranes The anterior and posterior intercostal membranes are aponeuroses located between the ribs and are continuations of the external and internal
intercostal muscles, respectively.
Scalp aponeuroses The
epicranial aponeurosis, or galea aponeurotica, is a tough layer of
dense fibrous tissue which runs from the
frontalis muscle anteriorly to the
occipitalis posteriorly.
Pennate muscles and aponeuroses Pennate muscles, in which the muscle fibers are oriented at an angle to the line of action, typically have two aponeuroses. Muscle fibers connect one to the other, and each aponeurosis thins into a
tendon which attaches to bone at the origin or insertion site. == Function ==
