- bulbospinal polio [DOID:0050514]
A paralytic poliomyelitis that results in destruction located in motor neurons of brainstem or located in motor neurons of spinal cord, has_material_basis_in Human poliovirus 1, has_material_basis_in Human poliovirus 2, or has_material_basis_in Human poliovirus 3, which are transmitted by ingestion of food or water contaminated with feces, or transmitted by direct contact with the oral secretions. The infection has symptom difficulty breathing, has symptom difficulty swallowing, and has symptom paralysis of arms and legs.
- tetanus [DOID:11338]
A primary bacterial infectious disease that results in prolonged contraction of skeletal muscle fibers, has_material_basis_in Clostridium tetani, which produces tetanospasmin, a neurotoxin, which is carried to the brain and spinal cord, where it binds irreversibly to receptors inhibiting neurotransmission. Damaged upper motor neurons cannot control reflex responses to afferent sensory stimuli.
- adult spinal muscular atrophy [DOID:0050529]
A spinal muscular atrophy that is characterized by progressive muscular weakness and motor disability that typically presents in the third decade of life and has_material_basis_in mutations in the SMN1 or SMN2 genes that are required for the survival of motor neurons.
- spinal polio [DOID:0050513]
A paralytic poliomyelitis that results in destruction located in motor neurons of spinal cord, has_material_basis_in Human poliovirus 1, has_material_basis_in Human poliovirus 2, or has_material_basis_in Human poliovirus 3, which are transmitted by ingestion of food or water contaminated with feces, or transmitted by direct contact with the oral secretions. The infection has symptom difficulty breathing, and has symptom paralysis of arms and legs.
- distal hereditary motor neuronopathy type 7A [DOID:0111201]
A distal hereditary motor neuropathy type 7 characterized by slowly progressive distal atrophy and weakness affecting first the upper limbs and later the lower limbs and vocal cord paresis that has_material_basis_in heterozygous mutation in SLC5A7 on 2q12.3.
- granulosa cell tumor [DOID:2999]
A sex cord-gonadal stromal tumor that has_material_basis_in granulosa cells and arises from the sex cord stroma.
- myelitis [DOID:322]
A spinal cord disease that is characterized by inflammation of the white matter or gray matter of the spinal cord.
