Impulse crosses over in the spinal cord
WitrynaThe impulse crosses a synapse (the junction between two nerve cells) between the sensory nerve and a nerve cell in the spinal cord. ... The impulse is sent up the spinal cord and through the brain stem to the thalamus, which is a processing center for sensory information, located deep in the brain. ... Over time, motor neuron diseases … WitrynaMost of the axons of the anterior corticospinal tract will decussate in the spinal cord just before they synapse with lower motor neurons.

WitrynaThe 1° afferent is a pseudounipolar neuron that has its cell body located in a peripheral (spinal or cranial) ganglion. It has a peripheral axon that forms or innervates somatosensory receptors and a central process that synapses with 2° afferent neuron (s) in a spinal cord or brain stem nucleus. WitrynaThe lateral corticospinal tract neurons cross the midline at the level of the medulla oblongata, and controls the limbs and digits. [1] [3] The lateral tract forms about 90% of connections in the corticospinal tract; [2] the vast majority cross over in the medulla, while the rest (about 2-3%) remain ipsilateral.

There it will likely pass through a short interneuron (D, in purple) before continuing down a motor neuron (E, in blue) to the origin of the signal.
