It stretches from the muscles in the calf ( gastrocnemius and soleus ) to the bone of the heel ( calcaneus ). (stoneclinic.com)
It is linked to the calcaneus (heel bone) by two Y-shaped arms, one of which connects to the navicular bone and the other to the cuboid bone. (healthncare.info)
The plantar fascia or plantar aponeurosis (you can use either term) originates from the medial tubercle of the calcaneus (heel bone) and continues forward to attach to the proximal phalanx of each of the toes (via the plantar plates). (yogauonline.com)
These fibers straighten in response to forces applied (like the heel-off phase of gait). (yogauonline.com)
Achilles tendinitis happens when-the band of tissues that directly connects the calf muscles at the back of the lower leg to your heel bone or calcaneus become affected. (outsourcestrategies.com)

In both noninsertional and insertional Achilles tendinitis, damaged tendon fibers may calcify (harden) over time. (orthoinfo.org)
In both non-insertional and insertional Achilles tendonitis, the damaged tendon fibers may calcify or harden. (hoagorthopedicinstitute.com)
Non-insertional Achilles tendonitis involves fibers in the middle portion of the tendon that have begun to degenerate (break down with tiny tears) and more commonly affects younger, more active people. (hoagorthopedicinstitute.com)
The plantaris muscle lies in the back of the leg with our calf muscles and inserts into the calcaneus next to the Achilles tendon. (naboso.com)
While both are the result of damage to the collagen fibers, the surrounding tissue at the insertion of the Achilles tendon is very different from the tissue near the midpoint of the Achilles. (runningwritings.com)
This type involves the middle portion of the Achilles tendon and is often characterized by microtears and degeneration of the tendon fibers. (drschoene.com)
If left untreated or aggravated, it can lead to a more severe condition known as Achilles tendinosis, which involves degeneration and thickening of the tendon fibers. (drschoene.com)

Collagen9
It is a thick white band of longitudinally extended collagen fibers. (docpods.com)
In a stretch injury, the collagen fibers are pulled but not torn. (stoneclinic.com)
This natural internal immune response floods the torn tissues with macrophage blood cells: one type to clean up the torn fibers and another to induce the production of new collagen by the local cells. (stoneclinic.com)
This process is augmented as the body releases stem-cell-derived self-repair cells from the perivascular to the torn collagen fibers. (stoneclinic.com)
Prolotherapy injections stimulate the growth of new collagen fibers, increasing the strength and stability of the tendon. (drschoene.com)
These tendons are made up of fibers of protein-rich connective tissues called collagen. (aidmyachilles.com)

Key Difference Between Tendons and Ligaments Following are the key differences between tendons and the ligaments: Tendon connects muscles to bone, and are present at the end of skeletal muscles and are made of white fibrous connective tissue, whereas ligaments connect one bone to another bone, so â ¦ Collagen fibers are formed together in parallel bundles that lie along the functional axis of the ligament. (montserrat-flights.com)
Plantar fascia3
The plantar fascia has elastic qualities in that its fibers are somewhat wavy in the relaxed position. (yogauonline.com)
In this condition the forces of gait are concentrated where the plantar fascia attaches to the calcaneus, instead of being distributed over the fascia and the muscles at the back of the legs. (yogauonline.com)
This microtrauma, if repetitive, can result in chronic degeneration of the plantar fascia fibers. (medscape.com)
Medial2
Two fibers, primarily the postero-lateral and anterior-medial fibers, make up this ligament. (healthncare.info)
A ligament of the lateral ankle that attaches the posterior portion of the talus, and a portion of the posterolateral calcaneus, to the medial malleolus. (montserrat-flights.com)
Talus2
During their oblique course, the most inferior fibers cover the tibiofibular corner of the joint and pass over the corresponding segment of the talus. (musculoskeletalkey.com)
The anterior facet lies on the anterior process of the calcaneus and articulates with the anterior calcaneal facet on the talus. (medscape.com)
Posterior4
The remaining fibers continue their course and insert on the distal tibia and they may reach the lateral border of the groove for the tibialis posterior tendon. (musculoskeletalkey.com)
At the posterior border of the tibial articular surface, the fibers change direction and become horizontal or transverse. (musculoskeletalkey.com)
Tendon transfer: This procedure uses some fibers from another tendon (the flexor digitorum longus, which helps bend the toes) to repair the damaged posterior tibial tendon. (doctorputnam.com)
Likened to a "nut in a nutcracker", posterior impingement syndrome is characterized by compression in the anatomic region between the posterior tibia and calcaneus during plantar flexion. (biomedcentral.com)

Bundles2
The muscle that you can feel moving underneath your skin is really made up of many smaller bundles of muscle fibers called fascicles. (medicinenet.com)
These levels are referred to as the primary, secondary and tertiary fiber bundles. (aidmyachilles.com)
Articular1
The superior calcaneal surface (see the following images) of the calcaneus has 2 parts: articular and nonarticular. (medscape.com)
Tendons2
Most of the time this remarkable process induces the torn tendons to heal-often with slightly thicker fibers and if exercise is applied occasionally, with a stronger tendon. (stoneclinic.com)
Tendons are packed with essential tissues and fibers to help you perform to your full ability, so keeping your tendon strong and healthy will benefit your whole body! (aidmyachilles.com)
Shorten1
Sliding together causes the muscle fibers to shorten and the muscle to contract and move the joint. (medicinenet.com)
Tissue2
The ends of the torn fibers die and, in the degradation, release catalytic enzymes that further break down the surrounding tissue. (stoneclinic.com)
The most common cause of a muscle or tendon strain is overuse, which weakens the tissue fibers. (medicinenet.com)
Bony1
The transition of muscle to tendon happens gradually as muscle fibers give way to tendon fibers before the bony attachment occurs. (medicinenet.com)
Occurs2
Normal healing occurs without a scar as the fibers themselves have not been torn. (stoneclinic.com)
We suture through tiny punctures in the skin, preserving the tendon sheath and the natural healing blood clot that forms around the torn fibers. (stoneclinic.com)
The muscle fiber may be just stretched, partially torn, or completely torn apart. (medicinenet.com)
Grade 2 strain has more significant damage, and some muscle fibers are damaged or torn. (medicinenet.com)

It typically has more fast-twitch type II muscle fibers, which are responsible for short, powerful bursts of activity such as running and jumping. (medscape.com)
The soleus muscle is made up of primarily slow-twitch type I muscle fibers and is responsible primarily for postural control. (medscape.com)
the transversus abdominus is a deep muscle with perpendicular fibers. (infoplease.com)
These, in turn, are made up of individual muscle fibers that are cross-linked to allow them to slide back and forth within the fascicle. (medicinenet.com)
When the muscle relaxes, the muscle fibers return to their resting position and as the fibers elongate, the joint may return to its previous position. (medicinenet.com)
A strain is a damage caused by an overstretched muscle or tendon, causing its fibers to be pulled apart, losing the ability to adequately contract. (medicinenet.com)
The damage can occur in three areas: the muscle itself, the muscle-tendon intersection where the muscle fibers transition to tendon fibers, or the tendon itself. (medicinenet.com)
Grade 1 strain usually causes stretching of a few of the muscle fibers. (medicinenet.com)
