Scanning electron microscopy (medicine) and olfactory fila (medicine)


Scanning electron microscopy (medicine)


scanning electron microscopy
<procedure> Technique of electron microscopy in which the specimen is coated with heavy metal and then scanned by an electron beam. The image is built up on a monitor screen (in the same way as the raster builds a conventional Television image). The resolution is not so great as with transmission electron microscopy, but preparation is easier (often by fixation followed by critical point drying), the depth of focus is relatively enormous, the surface of a specimen can be seen (though not the interior unless the specimen is cracked open) and the image is aesthetically pleasing.


olfactory fila (medicine)


olfactory fila -->
olfactory nerves


Collective term denoting the numerous olfactory filaments: slender fascicles each composed of the thin, unmyelinated axons of 8 to 12 of the bipolar olfactory receptor cells in the olfactory portion of the nasal mucosa; the olfactory filaments pass through the cribriform plate of the ethmoid bone and enter the olfactory bulb, where they terminate in synaptic contact with mitral cells, tufted cells, and granule cells.

See: olfactory tract.

Synonym: nervi olfactorii, fila olfactoria, first cranial nerve, nerve of smell, olfactory fila.
