Figure 7. — a. Cross section of an abdominal segment ganglion on the ventral nerve (0 h control). Neuron perikaryons 

 (N) are present ventral to the large ventral nerve tract (T). 1 10 X . b. Sagittal section of an ahdominal segment ganglion at 

 4 h postmortem. The neuron perikaryons are rounded and have pyknolic nuclei. Nerve cell processes, neurolemmal 

 and glial cells in the nerve tract show no apparent autolysis. 220 X. c. Cross section of the ventral nerve at 12 h postmor- 

 tem. Nerve cell processes are not evident and neurolemmal and glial cells possess pyknotic nuclei. 200 X . d. Cross section 

 of the ventral nerve at 24 h postmortem. Only supportive fibrous tissue elements and eosinophilic debris remain. 190 X. 

 e. Cross section of ventral nerve at 48 h postmortem. Fibrous elements are still present. 200 X . f. Ventral nerve in cross 

 section at 72 h postmortem. The Hbrous elements of the nerve are still present. 120 X .
