Paralysis of the radial nerve leads to a loss of function of the muscles involved in forelimbextension (protraction). See also 'radial paralysis stance'.

A typical stance seen in horses with a partial or complete paralysis of the radial nerve. The radial nerve innervates the extensor muscles of the forelimb, so in case of paralysis, the elbow is dropped, the carpus and the fetlock are flexed with the tip of the hoof or the dorsal hoof wall resting on the ground. In most cases, if the limb is manually placed in the correct position, the horse can bear weight.

The process of projecting x-ray beams (a type of electromagnetic radiation) towards an object and capturing the rays that pass through the object on a film or digital detector. The proportion of rays that are absorbed depends on the density and thickness of the object.

The main long bone in the forearm. At its proximal end, together with the ulna, it forms the elbow joint with the humerus. At its distal end it forms the radiocarpal joint with the proximal carpal bones.

Part of the process of trimming and dressing a hoof. Rasping involves removing horn from the wall of the hoof using a rasp.

A term used very rarely in the English language to refer to a digit (the three phalanges) together with its associated metacarpus or metatarsus. The German equivalent (Strahl) is encountered more frequently, particularly with regards to the evolution of Ungulates (mammals which have less than 5 digits or rays). Horses have only one 'ray' i.e. only one metacarpus/tarsus and one set of phalanges per limb.

A metalworking tool used to finish pre-punched or pre-drilled holes - both in term of accuracy of size and in terms of quality of finish.
