Apex Flashcards
Which spinal tract is monitored by somatosensory evoked potentials? Spinothalmic Corticospinal Dorsal Column Vestibulospinal
Dorsal column
Describe and organization of the 3 neuron pathway common to the spinal tracts
Each pathway consists of 3 neurons:
the first order neuron links the peripheral nerve to the spinal cord or brainstem
the second order neuron links the spinal cord or brainstem to a subcortical structure
the third order neuron links the subcortical structure to the cerebral cortex
