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 CSF is secreted by the choroid plexuses, which are found in the cavities of the brain. After being produced, the CSF then circulates through the ventricles of the brain and …
