Nifedipine is a first generation calcium channel blocker used to treat hypertension and angina pectoris. Nifedipine therapy is associated with a low rate of serum enzyme elevations and has been linked to several instances of clinically apparent acute liver injury. Background.
The Achilles tendon or heel cord, also known as the calcaneal tendon (Latin: Tendo calcaneus), is a tendon of the back of the leg, and the thickest in the human body. It serves to attach the plantaris, gastrocnemius (calf) and soleus muscles to the calcaneus (heel) bone.
Tendons like the Achilles tendon have what is known as a tendon organ. This is a proprioceptor located in the area where a tendon and muscle connect that helps to detect the tension being applied to a muscle. We sometimes call tendon organs Golgi tendon organs or Golgi organs for short. Do not, however, confuse the Golgi tendon organs with the Golgi apparatus found inside of your cells. The Golgi organ relays tendon changes to the brain. Once Achilles' heel was pierced by the arrow, the Golgi organ in the Achilles tendon and the muscles connecting to it would have sent signals up to the central nervous system to relay the position of Achilles' damaged muscles and leg.
