The thick band of fibrous tissue on the sole of the foot.
a long band of connecting tissue running from the heel to the ball of the foot.
The plantar fascia is a band of connective tissue on the plantar surface of the heel that plays a large role in maintaining the normal architecture of one's foot.
The plantar fascia is perhaps more correctly called the plantar aponeurosis, and it lies on the surface of the muscles of the sole of the foot. The plantar fascia has a thick and strong central part, which covers the central muscle of the 1 st layer, flexor digitorum brevis, and is immediately deep to the superficial fascia of the plantar surface. It is attached proximally to the heel bone (calcaneus) at the anterior calcaneal tubercle, the site of the muscle attachments, while distally it blends with the skin at the creases of the base of the toes, and also sends five slips, one to each toe. Each of these split into two, which pass deeply, one on each side of the flexor tendons of that toe, and finally fuse with the deep transverse metatarsal ligaments. The plantar fascia acts as a mechanical truss or a platform that passively stabilises the foot, maintaining the integrity of the medial longitudinal arch.
The tight band of tissue beneath the arch of the foot, connecting the heel and ball of the foot.
band of connective tissue that anchors the calcaneus to the front of the foot in order to support the arch
The "bowstring-like" tissue stretching from the heel underneath the sole.
The plantar fascia (or plantar aponeurosis) is the thick connective tissue which supports the arch of the foot. It runs from the tuberosity of the calcaneus forward to the heads of the metatarsal bones. It is the source of the painful condition of plantar fasciitis.
