Order the events for the detection of somatic sensation. Place a1 by the first event, a 2 by the second and so on.
The central process transmits the action potential to asecond-order sensory neuron in the CNS.
The action potential is transferred to the central process in theposterior root ganglion.
The stimulus triggers an action potential.
The signal is transferred to other (third order) CNS sensoryneurons for eventual perception and interpretation.
The action potential is propagated along the peripheral process ofthe neuron.
