Histochemistry of the neurosecretory cells of the pars intercerebralis of the dragonfly, Orthetrum chrysis (Selys) (Anisoptera: Libellulidae)
Odonatologica , Volume 4 - Issue 4 p. 225- 235
The neurosecretory cells, A, B and C, of the pars intercerebralis in O. chrysis (Selys) differ from one another in their neurosecretory material (NSM). The cerebral NSM is a muco-proteinaceous complex with glycogen entirely absent. Arginine is present in the NSM of all the above neurosecretory cells. However, the NSM of A cells contains a higher concentration of proteins having cystine or cysteine amino acids than that of the C cells; while the NSM of B cells contains virtually only those proteins which are rich in basic amino acids with negligible amounts of cystine or cysteine amino acids.
