C
Anatomical term meaning situated on the same side of the body (neighbouring structures). Can also refer to structures situated on either side of another structure e.g. collateral ligaments situated on either side of a joint or collateral cartilages situated on either side of the distal phalanx.
Flat, wing-like structures made from fibro-cartilage that are attached to the palmar/plantar processes of the distal phalanx (coffin bone) and extend proximaly to above the level of the hoof capsule. They can be palpated proximaly to the coronary band in the lateral and medialpalmar/plantar region of the pastern where they should yield to gentle pressure. The cartilage can ossify in part or completely (sidebone).
