GENERAL HISTOLOGY

Detailed explanation-1: -The calcaneal tendon, also known as the tendon of Achilles, is a posterior leg tendon-a fibrous connective tissue that joins muscles in the back of the leg. It is formed when the soleus muscle tendon joins with the gastrocnemius tendon.

Detailed explanation-2: -The Achilles tendon is a thick band of tissue that attaches your calf muscle to your heel bone.

Detailed explanation-3: -Lastly, the Achilles tendon does not have a true synovial sheath but instead is surrounded by a paratenon. The paratenon is made up of a loose connective tissue sheath surrounding the entire tendon and can stretch to 2 to 3 cm with movement to allow for the greatest possible gliding action.

Detailed explanation-4: -An Achilles tendon rupture is a complete or partial tear that occurs when the tendon is stretched beyond its capacity. Forceful jumping or pivoting, or sudden accelerations of running, can overstretch the tendon and cause a tear. An injury to the tendon can also result from falling or tripping.
