Neuronephric
Concerning the nervous and renal systems.
-
Neuronavigation
Radiological guidance for neurosurgery. The surgeon may rely on information obtained from ultrasonic images (“sononavigation”), magnetic resonance images, PET scans, or CT data, to select tissues for excision while avoiding eloquent (speech-controlling) regions of the brain.
-
Neuronal intestinal dysplasia
A disorder of bowel motility in which the innervation of the intestines is ectopic, i.e., the ganglions that provide nervous control of intestinal musculature are misplaced.
-
Preganglionic neuron
A neuron of the autonomic nervous system whose cell body lies in the central nervous system and whose axon terminates in a peripheral ganglion, synapsing with postganglionic neurons.
-
Peripheral motor neuron
A motor neuron that transmits impulses to skeletal muscle.
-
Peripheral neuron
A neuron whose process constitutes a part of the peripheral nervous system (cranial, spinal, or autonomic nerves).
-
Ganglion neuron
A neuron of the retina that receives impulses from bipolar neurons. Axons of ganglion neurons converge at the optic disk to form the optic nerve.
-
Commissural neuron
A neuron whose axon crosses to the opposite side of the brain or spinal cord.
-
Central neuron
A neuron confined entirely to the central nervous system.
-
Associative neuron
A neuron that mediates impulses between a sensory and a motor neuron.
