feedback4="'''Correct!''' Equine motor neuron disease is a generalised lower motor neuron disorder of particularly postural muscles of the body limbs, neck and sacrocaudalis medialis leading to diffuse weakness and a raised tail head. There is degeneration of ventral horn motor neurons, chromatolysis, neurofilament accumulation, gliosis, Wallerian degeneration and denervation changes in the muscle.

feedback2="'''Incorrect.''' Stringhalt is a distal axonopathy especially of large diameter fibres, but its causes are poorly understood. The correct answer is equine motor neuron disease, which is a generalised lower motor neuron disorder. There is degeneration of ventral horn motor neurons, chromatolysis, neurofilament accumulation, gliosis, Wallerian degeneration and denervation changes in the muscle.

feedback1="'''Incorrect.''' Cauda equina neuritis is the equine version of idiopathic polyradiculoneuritis. Extradural nerve roots of cauda equina are thickened and discoloured and there is an inflammatory infiltrate, extensive axonal damage and demyelination. The aetiology unknown. The correct answer is equine motor neuron disease, which is a generalised lower motor neuron disorder. There is degeneration of ventral horn motor neurons, chromatolysis, neurofilament accumulation, gliosis, Wallerian degeneration and denervation changes in the muscle.

feedback3="'''Incorrect.''' Suprascapular nerve injury or 'Sweeney' is caused by the horse colliding into an object. There is fibrous entrapment as the nerve is reflected around the wing of the scapula, resulting in atrophy of supra- and infra- spinatous muscles. The correct answer is equine motor neuron disease, which is a generalised lower motor neuron disorder. There is degeneration of ventral horn motor neurons, chromatolysis, neurofilament accumulation, gliosis, Wallerian degeneration and denervation changes in the muscle.

feedback5="'''Incorrect.''' Distal denervating disease is a distal axonopathy, possibly of toxic origin. It is a condition of small animals, not large animals.
