Anat 315 compartments of the leg (b) There are 2 sub-groups of the posterior compartment: superficial group (gastrocnemius, soleus, plantaris, deep group (popliteus, tibialis posterior, flexor halluces longus, flexor digitorum) Tibial nerve innervates all the muscles in this compartment. Flexing the ankle & knee (but not at the same time) Its tendon runs between gastrocnemius & soleus to insert on. Wide fleshy superficial muscles that has two bellies. There is an arch between the 2x origins of soleus that allow nerves and vessels to pass through (note similarities with. Has tiny muscle and thin belly (note similarities with palm. Back of interosseous membrane and adjacent bones (tibia + Belly occupies the back of the lower tibia. Similar to it"s upper limb homologue (fdprofundus) in that it also gives off.
