Posterior view of muscles of the extensor region of forearm; digital extensors have been reflected.

Arteries and nerves of anterior and lateral aspects of leg and dorsum of foot. A. dissection, anterolateral view. The anterior crural muscles were removed, and the fibularis (peroneus) longus muscle was excised.

Transverse MRI of forearm: CV, cephalic v; FCR, flex carpi rad; RV, radial vessels; FDS, flex dig super; UV, ulnar vessels; FCU, flex carpi ulnaris; AV, ant interos vessels; INT, interos mem; FDP, flex dig profundus; FPL, flex pol long; U, ulna; R, radius

Anterior view of the bones of the forearm and hand showing muscle attachments.

Dissection of posterior leg, deep compartment, posterior view. A. Superficial dissection. The tendo calcaneus (Achilles tendon) is divided and the gastrocnemius muscle and a horseshoe-shaped section of the soleus muscle are removed.

Posterior leg, superficial compartment, posterior view. C. Deeper dissection. The fleshy bellies of the gastrocnemius muscle are largely exised, and the proximal attachment of the soleus muscle is thereby exposed; the plantaris muscle is absent from this
