− | 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.
