So our effective organ, in this case, our biceps tissue, the biceps muscle. So basically, we have a single axon traveling all the way to the target tissue, the target muscle. Now let's move on to our sensory neuron. So sensory neurons are those neurons that connect to receptors. These receptors basically pick up stimuli, and this stimulus is transformed into an electrical signal by those sensory neurons of the somatic nervous system. So these somatic sensory neurons then carry our electrical signal via a single axon, as in this case, and they carry that signal to the backside, which is our dorsal side of our spinal cord.
