What is plantar aponeurosis?

The Plantar aponeurosis is the modification of Deep fascia, which covers the sole. It is a thick connective tissue, that functions to support and protect the underlying vital structures of the foot. The fascia is thick centrally, known as aponeurosis and is thin along the sides.

Where does the plantar aponeurosis insert?

The plantar fascia is a thickened fibrous aponeurosis that originates from the medial tubercle of the calcaneus, runs forward to insert into the deep, short transverse ligaments of the metatarsal heads, dividing into 5 digital bands at the metatarsophalangeal joints and continuing forward to form the fibrous flexor …

Where does the plantar fascia aponeurosis run?

The plantar aponeurosis, also known as the plantar fascia, is a strong layer of white fibrous tissue located beneath the skin on the sole of the foot. Towards the front of the foot, at the mid-metatarsal level, it divides into five sections, each extending into a toe and straddling the flexor tendons.

Is plantar fascia and aponeurosis the same?

The plantar fascia (also known as the plantar aponeurosis) is located superficially plantar side of the foot.

What is aponeurosis and its function?

Aponeuroses are connective tissues found on the surface of pennate muscles and are in close association with muscle fascicles. In addition to transmitting muscle forces to the external tendon, aponeurosis has been hypothesized to influence the direction of muscle shape change during a contraction.

Why does my plantar aponeurosis hurt?

Plantar fasciitis can be caused by a number of factors, including type of shoes, foot structure, overuse and types of walking surfaces. The main symptom of plantar fasciitis is heel pain. Treatment for plantar fasciitis usually does not require surgery.

What attaches to the plantar aponeurosis?

The plantar aponeurosis (PA) originates from the calcaneal tubercle and extends to the forefoot. The aponeurosis consists of a medial, central and lateral part. The medial and lateral parts attach to the abductor hallucis and the musculus abductor digiti quinti pedis, respectively.

Where is aponeurosis located?

Aponeuroses are connective tissue sheaths found on the surface of pennate muscles. They are continuous with external tendons and serve as insertion sites for pennate muscle fascicles that do not extend from muscle origin to insertion (14).

What does aponeurosis mean in anatomy?

aponeurosis, a flat sheet or ribbon of tendonlike material that anchors a muscle or connects it with the part that the muscle moves. The aponeurosis is composed of dense fibrous connective tissue containing fibroblasts (collagen-secreting spindle-shaped cells) and bundles of collagenous fibres in ordered arrays.

Is aponeurosis a tendon?

What is the difference between a tendon and an aponeurosis?

An aponeurosis looks quite different than a tendon. An aponeurosis is made of layers of delicate, thin sheaths. Tendons, in contrast, are tough and rope-like. An aponeurosis is made primarily of bundles of collagen fibers distributed in regular parallel patterns, which makes an aponeurosis resilient.
