Phenotype: motor neuron neuromuscular junction increased volume, abnormal
Note: This statement combines anatomy and/or ontology terms with phenotype quality terms to create a complete phenotype (EQ) statement. For detailed information on individual terms, click the hyperlinked term name.
Name: motor neuron
Synonyms: motoneuron
Definition: An efferent neuron that passes from the central nervous system or a ganglion toward or to a muscle and conducts an impulse that causes movement.
Ontology: Anatomy Ontology [ZFA:0009052]
Name: neuromuscular junction
Synonyms: motor endplate, NMJ
Definition: The junction between the axon of a motor neuron and a muscle fiber. In response to the arrival of action potentials, the presynaptic button releases molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane of the muscle fiber, leading to a change in post-synaptic potential.
Ontology: GO: Cellular Component [GO:0031594]    QuickGO    AmiGO
Name: increased volume
Synonyms: high volume, large volume
Definition: A volume which is relatively high.
Ontology: Phenotypic Quality Ontology [PATO:0000595]
