A Histochemical Study of the Connective - Tissue Sheath of the Nervous System of Periplaneta americana
نویسنده
چکیده
The connective-tissue sheath surrounding the nervous system of Periplaneta americana consists of two layers, the neural lamella and the sheath cells beneath it. The neural lamella is composed of a collagen-type protein and neutral muco-polysaccharide. The sheath cells possess numerous lipochondria and mitochondria; the former consist of phospholipid and some cerebroside. The cytoplasm of the sheath cells contains some RNA, glycogen, and lipid.

The Connective - Tissue Sheath of the Nervous System of
THE connective-tissue sheath around the nervous system of insects began to attract attention after Hoyle (1953) had shown that it was essential for the normal functioning of the nervous system in Locusta migratoria. The sheath, which consists of two layers, the neural lamella and the sheath cells, controls the passage of ions from the haemolymph into the nervous system. In electron-microscope s...
متن کاملThe ultrastructure of the perineurium in two insect species, Carausius morosus and Periplaneta americana.
The organization of the perineurium in two insect species (Carausius morosus and Periplaneta americana) has been examined with the electron microscope. In both species this cellular layer has been found to possess an extensive system of tortuous channels between the lateral cell walls. These channels are open at the outer margin adjacent to the fibrous connective-tissue sheath, but appear to be...
متن کاملThe penetration of acetylcholine into the central nervous tissues of an insect (Periplaneta americana L.).
The precise physiological role of acetylcholine in synaptic transmission in the insect central nervous system has been a subject of some speculation and controversy. One of the main difficulties involved in postulating the existence of a conventional cholinergic system in the insect central nervous system has been the relative insensitivity of intact ganglia to applied acetylcholine solutions (...
متن کاملThe Fine Structure of Nerve Cells and Fibers, Neuroglia, and Sheaths of the Ganglion Chain in the Cockroach (Periplaneta americana)
The abdominal nerve cord of Periplaneta americana was studied utilizing light and electron microscopes. In the nerve cells, delicate granules, similar to those probably responsible for cytoplasmic basophilia, are evenly distributed in "dark" cells and clumped in "light" cells. Neuroglial cells are stained metachromatically by cresyl violet. The neuroglial cells have many processes which ramify ...

The organs and tissues of insects are mostly composed of single layers of cells separated from the circulating blood by thin connective tissue membranes (Wigglesworth, 1956a; Pipa & Cook, 1958). The supply of nutrients to such organs presents no problem. But the central nervous system is an exception. The ganglia are the only solid organs in the insect body. They consist of densely packed perip...
