Question

Achilles tendon is associated with
A. Hamstring muscle
B. Gluteus muscle
C. Quadriceps muscle
D. Gastrocnemius muscle

Answer 1

Hint: The tendons are made up of collagen and are quite similar to ligaments that connect one bone to another. Tendons connect muscle to bone, or we can say tendon is a tough band of fibrous connective tissue that connects muscle to bone and can withstand the tension.

Complete answer:
The Achilles tendon or heel cord is the tendon present in the back of the lower leg. Achilles tendon is the thickest and most powerful tendon in the human body and attaches the gastrocnemius (calf) and soleus muscles to the calcaneus (heel) bone.
The gastrocnemius muscle is active in walking, jumping and running and composed predominantly of type II fibers.
The soleus muscle works as a stabilizer to the foot while standing and is composed primarily of type I fibers.
The blood supply in the Achilles tendon is from the longitudinal arteries which course the length of the tendon from two main blood vessels.
Posterior tibial artery supplies the proximal and distal sections.
Peroneal artery supplies the blood in the middle section.
The Achilles tendon has a poor blood supply throughout its length, as measured by vessels per cross-sectional area.
The Achilles tendon is easy to damage with repetitive use or overload, commonly athletes suffer this kind of injury. The most common type of injuries are because of the overuse of the Achilles tendon disorders, approximately 55%-65% are diagnosed as Achilles Tendinopathy.
Complete ruptures of the Achilles tendon take place in sport activities, including basketball and soccer.
Achilles tendon is associated with the gastrocnemius muscle.

So, option D is the correct answer.

Note:
To diagnose the Achilles rupture, the test perform are:-
> The matless test is a visual diagnostic test for suspected Achilles tendon rupture.
> The Thompson test is used to identify the presence of a complete Achilles tendon rupture and is performed by squeezing the calf.
