They are very sparingly supplied with blood-vessels, the smaller tendons having in their interior no trace of them. This type of fascia is commonly referred to as myofascial tissue or “the fuzz” and From Dorland's, 2000. Muscle is a soft contractile tissue that helps to produce motion. It forms a strong investment which not only binds down collectively the muscles in each region, but may give a separate sheath to each, and to the vessels and nerves as well. The aponeuroses are flattened or expanded tendons, of a pearly-white color, iridescent and often glistening; they are only sparingly supplied with blood vessels. On dissecting a human body, one comes across various structures in and around the muscles apart from blood vessels, bones and nerves. The fasciae and muscles may be grouped into those of the head and neck; of the trunk; of the upper limb; and of the lower limb. Moreover, aponeurosis is a delicate connective tissue while the tendon is a tough connective tissue. It varies in thickness in different parts of the body; in the groin it is so thick that it may be subdivided into several laminae. The plantar aponeurosis (PA), or plantar fascia, is the strong, fibrous investing layer of the sole of the foot (,1). is that aponeurosis is (anatomy) a flattened fibrous membrane, similar to a tendon, that binds muscles together or connects them to other body parts like skin or bone while fascia is a wide band of material covering the ends of roof rafters, sometimes supporting a gutter in steep-slope roofing, but typically it is a border or trim in low-slope roofing.

The bottom of the plantar aponeurosis close to the heads of the metatarsals splits into five straps, one for every toe. Fascia is, in fact, our system of Biomechanical Regulation – just as our circulatory system is a chemical regulator and the nervous system is a timing regulator – and needs to be studied and treated as a system, not just as a series of parts. Reynolds JW, Bostrom CF. The interval between the 2 muscle groups is bluntly developed. The term plantar fascia and plantar aponeurosis are used interchangeably in the literature. aponeurosis - Keyword Search - Science Photo Library. In the limbs, the fascia not only invests the limb, but gives off septa, which separate the various muscles, and are attached to the periosteum these prolongations of fasciae are usually spoken of as intermuscular septa. Their primary function is to join muscles and the body parts they act upon, whether it be bone or other muscles. Aponeurosis, fascia, tendon and ligament are several structures associated with muscles and bones. As the attachment of the TFL at the gluteal aponeurosis stays intact, the TFL remains enveloped within the layers of the fascia lata posteriorly and distally [23]. call this type of fascia a sheath, membrane, aponeurosis, superficial fascia, epimysium or dense connective tissue.
