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 dendrite membrane. Note that this very early (1954) micrograph is primarily of historical interest since it pre-dates glutaraldehye fixation which was introduced in the early 60's and is considered essential for adequate nerve tissue preservation. Examples of nerve tissue micrographs prepared in 1965 are CIL:37218, CIL:37219 and CIL:37220. Image made available by James D.
