Transmission electron micrograph of a nerve cell synapsing on a dendrite. The synapse contains many synaptic vesicles and a cluster of mitochondria. Note that this very early (1953) micrograph is pr...

This study of the zebrafish eye is a series of four images taken at increasing magnifications. The first image is the SEM block face of the zebrafish eye. This is followed by a second image that is ...
