Final answer:
True. The Achilles tendon is common to both the gastrocnemius and the soleus muscles.
Step-by-step explanation:
True. The Achilles tendon is indeed common to both the gastrocnemius and the soleus muscles.
The Achilles tendon is a strong connective tissue that connects the calf muscles, including the gastrocnemius and soleus, to the heel bone (calcaneus).
This tendon is responsible for transmitting the force produced by the contraction of these muscles, allowing for movements such as plantar flexion, which occurs when you stand on tiptoe or push off the ground with your foot.
