Neurons. (A) Left panel: normal motor neuron in ventral horn of spinal cord. The dark granules are the Nissl granules. The pale area is the region occupied by lipofuscin. Right panel: neurons showing the features of ischaemic cell change. They are shrunken and contain hyperchromatic nuclei, have intensely eosinophilic and luxophilic cytoplasm and may be decorated by incrustations. (B) Similar neurons showing the features of central
chromatolysis. Note the pale homogeneous cytoplasm and the eccentric nucleus.
