Both of these neurons when injured, present with their own set of clinical signs. A lower motor neuron lesion is a lesion which affects nerve fibers traveling from the lower motor neuron(s) in the anterior horn/anterior grey column of the spinal cord, or in the motor nuclei of the cranial nerves, to the relevant muscle(s). Lower motor neuron syndromes are clinically characterized by muscle atrophy, weakness and hyporeflexia without sensory involvement 1) .

The term lower motor neuron lesion refers to any disorder producing loss of function of the lower motor neuron supply to somatic musculature. Typically, patients with a bulbar palsy present with signs and symptoms of the cranial nerves affected as mentioned. Muscle spindle. Dysfunction of the UMN • Gait Generation Dogs/cats- brainstem People- cerebrum . 1. The symptoms of UMN damage require differentiation from damage to lower motor neurons which would manifest with weakness, muscle atrophy, hypotonia, hyporeflexia, fasciculations, and fibrillation.

MND involves all diseases that involve selective loss of function of the upper and / or lower motor neurons innervating the voluntary musculature of the limbs and bulbar regions. Although weakness may be readily apparent, it may take A focal lesion may cause an associated lower motor neuron (LMN) lesion at the level, especially if the process also affects the nerve root, we call this a myeloradiculopathy (this is rare though) T1-T9 lesions interrupting the sympathetic outflow, Neurogenic shock may occur: this is a form of distributive shock occurring with bradycardia & loss of vascular tone ‘hypotension’.

Motor signs and symptoms Lower motor neuron (LMN) signs (Table 1) are found in a limb if some of its muscles are innervated by anterior horn cells (lower motor neurons) affected at the level of the spinal cord lesion. Lower motor neurons actually signal the muscle to contract. Motor neuron disorders (MNDs) are a clinically and pathologically heterogeneous group of neurologic diseases characterized by progressive degeneration of motor neurons; they include both sporadic and hereditary diseases. • Following upper motor neuron lesions, affected muscles potentially have many features of altered performance including: • weakness (decreased ability for the muscle to generate force) As discussed in the UMN article, an UMN may synapse directly or indirectly, via interneurons, onto a LMN..
