This group is situated in the back of the decrease leg, near its floor. The calcaneal tendon can be a part of this group.
The aim of the calcaneal tendon is to connect the soleus muscle tissues and calf muscle tissues (plantaris and gastrocnemius) to the heel bone, scientifically generally known as the calcaneus. The plantaris muscle tendon, if current, assists on this course of by inserting into the calcaneal tendon’s medial border (the facet closest to the midline of the physique).
The calcaneal tendon is the strongest and thickest tendon within the physique.
