Gastrocnemius muscle the medial condyle of the femur. Its other end forms a common tendon with the soleus muscle; this tendon is known as the calcaneal tendon or Achilles Tendon and inserts onto the posterior surface of the calcaneus, or heel bone. Further, it is considered a superficial muscle as it is located directly under skin, so its shape is clearly visible in a normal human being. Deep to the gastrocnemius (farther from the skin) is the soleus muscle. Some anatomists consider both to be a single muscle, the triceps surae or "three-headed [muscle] of the calf", since they share a common
Stylohyoid muscle and superior direction. Stylohyoid muscle The stylohyoid muscle is a slender muscle, lying anterior and superior of the posterior belly of the digastric muscle. It shares this muscle's innervation by the facial nerve, and functions to draw the hyoid bone backwards and elevate the tongue. Its origin is the styloid process of the temporal bone. It inserts on the body of the hyoid . It arises from the posterior and lateral surface of the styloid process of the temporal bone, near the base; and, passing inferior and anterior, it is inserted into the body of the hyoid bone, at its
