At what point do the axons of the spinothalamic pathway cross to the opposite side of the central nervous system? The spinothalamic pathway crosses immediately as it enters the spinal cord and ascend contralaterally Axons of the spinothalamic pathway cross at the level of the medulla (brainstem area) and ascend to the contralateral side of the thalamus Axons of the spinothalamic pathway cross to the primary somatosensory cortex on the contralateral side when they are leaving the thalamus. Axons of...

The reason visceral pain is referred to surface structures is that 56. Al there are no nociceptors in internal organs, so visceral sensory neurons must stimulate somatic sensory neurons to get a response B) P is produced only in second-order sensory neurons that are used for both sensory and somatic sensations the affected organ has been removed, so the brain localizes the pain in the nearest remaining ters released at the site of injury diffuse through the interstitial fluid to...

L- DOPA, a treatment given to Parkinsons patients, can produce dyskinesia a negative side effect involving tics or uncontrollable movement patterns, cause 1) L-DOPA activates the indirect pathway of the basal Ganglia. 2) L-DOPA is converted into dopamine in the substantia Nigra. Substancia Nigra neurons then project down the spinal cord and excite alpha motor neuron pools. 3)L-DOPA crosses the low brain barrier (BBB) and travels to the primary motor cortex activating random muscle groups. 4) L-DOPA is taken up...
