With regard to new methods of diagnostic imaging, sectional anatomy of the equine front toe was described by E 12 plastic-em bedded slices. In two specimens red coloured epoxy resin biodur E 12 was injected into the second common digital palmar artery before sagittal cutting. The E 12 plastic-em bedded slices were compared with natural, S 10 plastinated specimens and corrosion costs of the vessels. By means of histological sections the microscopic morphology and mechanical function of the so-called "T-ligament" of the deep digital flexor tendon could be understood. In all 12 equine front toes underwent examination. Plastinated slices are durable and especially E 12 plastic-embedded slices transparent. Sections with injected vessels represent the best anatomic basis of comparison. The "T-ligament" of the deep digital flexor tendon consists of thin, disordered collagen fibers, interweaved with a remarkable number of elastic fibers. The "T-ligament" contains plenty of microscopic small blood vessels, nerves and collateral lymphatic vessels and is free of fatty tissue. The "T-ligament" forms a bridge of connective tissue, its function is interpreted as an exceptional flexible and elastic structure, which stretches under load in proximal direction and offers necessary reserves for the synovial fluid extension of the coffin-joint and the navicular bursa. Instead of the term "T-ligament", for this bridge of connective tissue the term "elastic layer between deep digital flexor tendon and middle phalanx" is suggested.
