Identify soleus
Soleus lies beneath gastrocnemius but still belongs to the superficial posterior muscle group of the leg.
A deeper position relative to gastrocnemius does not place soleus in the deep posterior compartment.

Principal attachments and heel connection
It attaches proximally to the back of the fibular head and upper shaft, and to the tibial soleal line.
Distally, gastrocnemius and soleus reach the calcaneus through the calcaneal (Achilles) tendon.
Here, tendon-colored boundaries and separate tendon layers are not modeled. The text describes anatomy beyond the selectable surface.

Ankle action and the knee
Soleus produces ankle plantar flexion. It does not cross the knee and is not a direct knee flexor.
Plantar flexion points the foot downward at the ankle. This static viewer does not animate the movement or predict strength, tendon load or range of motion.

Innervation
The tibial nerve supplies the muscle. Its branches and the supplying blood vessels are not present in the current model.

Explore right soleus in 3D
- Orient the selected structure. Inspect it in isolation from Back. Restore context to see how gastrocnemius can cover its surface; Isolate reveals it again.
- Restore this side. Show context restores the existing 31 bones and 21 muscle parts in this leg. Select the calcaneus to inspect the heel; the Achilles tendon is not a separate selectable item.
- Compare the calf layers. The regional lower-leg close-up omits the femur and foot bones, including the heel. This full-leg structure page includes those bones when context is restored. Right calf guides →
BodyParts3D provides this right-sided surface model, not every anatomical variant. Colors distinguish structures; they are not tissue textures.
Soleus is a separate muscle, not a third gastrocnemius head. The source surface does not expose its internal fascicles.
Plantaris, nerves, vessels, joint cartilage and separate ligaments are absent. A colored taper is not a detailed model of Achilles subtendons or tendon fascicles.
The left and right guides share general anatomy but open different source-identified meshes. These surfaces do not represent all anatomical variants.
A section tool is not available for this structure. The surface model does not reveal internal tissue architecture or represent a medical scan.
Sources and editorial status
This guide uses independently written explanations with links to the evidence behind them. Source checking and specialist anatomical review are separate steps; the latter is still pending.
