Anatomy

Anterior abdominal aponeuroses

The anterior abdominal aponeuroses are located just superficial to the

latissimus dorsi

.

Posterior lumbar aponeuroses

The posterior lumbar aponeuroses are situated just on top of the epaxial muscles of the thorax, which are

sacrospinalis

.

Palmar and plantar aponeuroses and extensor hood

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

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

Like tendons, aponeuroses attached to pennate muscles can be stretched by the forces of muscular contraction, absorbing energy like a spring and returning it when they recoil to unloaded conditions.^[3] Also serving as an origin or insertion site for certain muscles e.g latissimus dorsi.
