What are the names of the muscles in your legs?

For the actions of the major muscles of the mammalian leg, see adductor muscle; biceps muscle; gastrocnemius muscle; gluteus muscles; quadriceps femoris muscle; sartorius muscle; soleus muscle.

The Gastrocnemius and Soleus are the muscles typically thought of as the “calf” muscles. They are the main sources of power for the motion of the ankle. The fascia (connective tissue) of these two muscles comes together to form the Achilles tendon at the back of our ankle.

Can pinched nerve cause calf pain?
