From: The problem of axonal injury in the brains of veterans with histories of blast exposure
Microscopic features of APP (+) axon abnormalities in motor vehicle crashes (a-c), blast (d-f) and opiate overdose (g-i) in typical cases. a is taken from Case 20, b and c from Case 21, d from Case 4, e from Case 5, f from Case 3, g from Case 9, h from Case 7 and i from Case 6. Insets represent enlargements of indicated areas. Note differences in size of axons among the three types of injury and also the prominence of undulations and axon bulbs in cases of motor vehicle crash (a-c). Portions of the insets are further magnified in Figure 7. Size bars: 50 μm.
