The achilles tendon, tendo calcaneus attaches distally to the calcaneual tuberosity, and arises superiorly from the triceps surae complex of the gastrocnemius and soleus muscles. Achilles tendon at foetus. The Achilles tendon connects muscle to bone, like other tendons, and is located at the back of the lower
[1] [2] The posterior aponeurosis and median septum join in the lower quarter of the muscle and then join with the anterior aponeuroses of the gastrocnemius muscles to form the calcaneal tendon or Achilles tendon and inserts onto the posterior surface of the calcaneus, or heel bone.
An enthesophyte, consisting of calcification deposits within the Achilles tendon at its calcaneal insertion. The Achilles tendon is wider than normal, further suggesting inflammation. Enthesophytes are abnormal bony projections at the attachment of a tendon or ligament. [1]
The ankle jerk reflex, also known as the Achilles reflex, occurs when the Achilles tendon is tapped while the foot is dorsiflexed. It is a type of stretch reflex that tests the function of the gastrocnemius muscle and the nerve that supplies it. A positive result would be the jerking of the foot towards its plantar surface.
Of all the large tendon ruptures, 1 in 5 will be an Achilles tendon rupture. An Achilles tendon rupture is estimated to occur in a little over 1 per 10,000 people per year. Males are also over 2 times more likely to develop an Achilles tendon rupture as opposed to women. Achilles tendon rupture tends to occur most frequently between the ages of ...
The triceps surae is connected to the foot through the Achilles tendon, and has three heads deriving from the two major masses of muscle. [1]The superficial portion (the gastrocnemius) gives off two heads attaching to the base of the femur directly above the knee.
Some anatomists consider both to be a single muscle—the triceps surae or "three-headed [muscle] of the calf"—since they share a common insertion via the Achilles tendon. The plantaris muscle and a portion of its tendon run between the two muscles, which is involved in "locking" the knee from the standing position.
These muscles unite in a large terminal tendon, the Achilles tendon, which is attached to the posterior tubercle of the calcaneus. The plantaris closely follows the lateral head of the gastrocnemius. Its tendon runs between those of the soleus and gastrocnemius and is embedded in the medial end of the calcaneus tendon. [32]
