Photic Sense Organs

The Physiology of Sense Organs

to the non-sporeforming anaerobes (Bacteroidaceae, anaerobic cocci, Lacto-bacteria and Corynebacteria, Actinomycetes). The book by Smith and Holdeman, published as part of the American Lecture Series in Clinical Microbiology, fills a void. Both authors have been working in the Anaerobic Bacteriology Laboratory at the Virginia Polytechnic Institute for years and draw on extensive experience, par...

Making sense of the role of sense organs in trichotillomania

The labyrinthine sense organs of the frog.

A study of the macula and crista organs of the frog's labyrinth with the use of an improved method of histological preparation has shown these endings to be more complex than heretofore believed. The structure lying over the layer of sensory and supporting cells is not a single "gelatinous" body as commonly described, but consists of two distinct layers with separate functions. In all these end...

The sense organs on the antennal flagellum of aphids

The cuticular parts of the aphid plate organ consist of an outer and an inner layer. Both are transparent and in the space between them are many fine branches of the half dozen, or more, sensory neurones which lie below the plate. Each dendrite narrows, a short distance above its cell body, and assumes the structure of a cilium with 9 pairs of peripheral fibrils, a ciliary collar, and basal bod...

The formation of sense organs in Drosophila: a logical approach.

The genetic analysis of development has revealed the importance of small sets of interacting genes in most morphogenetic processes. The results of gene interactions have so far been examined intuitively. This approach is largely sufficient when one deals with simple interactions, a feedback circuit for example. As more components become involved, however, it is difficult to make sure that the i...
