Transmission electron micrograph of an axon from a rat tongue surrounded by a myelin sheath. Image made available by James D. Jamieson and the Department of Cell Biology, Yale University School of M...

Transmission electron micrograph of nerve cells at the thigh muscle motor end plate. The motor end plate is the highly-excitable region of muscle fiber plasma membrane responsible for initiation of a...

Electron micrograph of an unmyelinated nerve Schwann cell from a rat tongue. Image made available by James D. Jamieson and the Department of Cell Biology, Yale University School of Medicine.

Transmission electron micrograph of nerve cell terminals on medulla dendrites. The body of the dendrite (lower part of image) contains aligned microtubules (neurotubule). Synapses are seem on the den...

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...
