It crosses the ankle joint and may be subtalor joint.
A muscle that, from origin to insertion, crosses two joints, and thus can produce an action at both joints. Example: the "hamstrings" (semimembranosis and semintendinosis) cross the hip joint and the knee joint and act on both joints (extend at hip, flex at knee).
rectus femoris
soleus
Tibia and fibula
Soleus and gastrocnemius
Soleus is the muscle that is located directly beneath the gastrocnemius and has similar functions to the gastrocnemius. The hamstrings muscles are a two joint muscle that acts at the knee and hip.
Biceps Brachii crosses both the Glenohumeral and Trochleoginglymoid joints. Sartorius crosses both the hip joint and knee. Others include tensor fascia lata, rectus femoris, semimembranosus, semitendinosus, biceps femoris, flexors of the forearm cross multiple joints as do the extensors. There are many others.
Hip and knee joints
glenohumeral and trochleoginglymoid joints
rectus fermris
biarticulate or biaxial muscles
The heel raise exercise works your calf muscles, which are two separate muscles. The first is the gastrocnemius muscle, which is the outermost calf muscle on the back of your lower leg. Your soleus muscle is the second part of your calf muscle and rests underneath the gastrocnemius. However, the soleus is slightly wider than the gastrocnemius.
