Document Summary

Ganglia: cluster of sensory nerve cells, near but outside of brainstem & spinal cord. Cluster together for specific purposes (primary motor cortex: forms smaller subcortical structures within white matter (caudate efficient (hand cell, hand movement, white matter is mylonated, damage to mylon sheet creates breakdown in message primary sensory cortex) Shades of grey (matter: consistent cluster of neuron cell bodies nucleus, patamen) White matter: clusters of myleninated atoms. Axon coated in myelin transmit electrical impulses much faster. Axon bundles connect two or more areas: subcortical matter is grey matter in white matter. Sensory neurons from sense organ (pain receptors) makes synapses with. Dorsal root ganglia send message to cns via. In spinal cord grey matter on inside and white matter on outside. In brain grey matter on outside and white matter on inside. Dorsal nerve root: bring sensory info from pns to cns via dorsal horn (part of the afferent pathway)
