On the follow mg page clearly dit. gram th e neuronal pathways described below and answer the questions th at are present op tha t Wl&t · Your neuronal pathways must be color-coded using the labels on the following page. That is, for ea~h of the neuron types you must pick a color and indicate it in the box next to that neuron label on th e follow~ng page . For example, if you select to color the preganglion.ic efferent neurons red, you muS t color th em red 10 all of the traces that use a preganglionic efferent neuron in the pathway . When ~r~wing the neurons , you must clearly draw the location of their cell body and synaptic junc~ons. The syna~tic _ Junctions must be represented like the pictures that you studied in the lecture manual, that is repre- sent 1t with a forked line. ~':ongly recommend that you do not use ink. Use cowred pencils that can be erased in case you have to !JUS t your answer. Your diagrams of the neurons must be clear and accurate to get credit. Illustrate the following neuronal pathways: a) se!! ~ pJlt.fr.om J l:le ) 0 !Yz t -Jim b (Box 1) via Level 4 that initiates skeletal wotor output both to th e same lower limb via that level and also to the contralateral upper limb {Box £\ii Level 1. b) sensory input from the epaxial region of the abdomen (Box 3) that initiates sympathetic output to an artery in the epatjaJ region of the abdomen . c) sensory input from the sigmoid colon (Box 4) that enters the spinal cord via the parasympathetic pathway a~d initiates both parasympathetic output to · the taenia coli of the sigmoid colon (Box 4) and sympathetic output to a blood vessd in the small intestine (Box 4).
