Emerging Identity in Cytophysiology of Synaptic and Neurosecretory Terminals
Comparison of the organization of presynaptic terminals that typically release neurotransmitters at specialized junctions with other cells, and neurosecretory endings contributing to neurohaemal complexes and releasing hormones into the blood stream, has been a feature of interest since the commencement of their study (e.g., see Palay, 1958). Although terminals show considerable variation, the great majority, whether synaptic or neurohaemal, have in common a highly distinctive pattern of ultrastructure (Figs. 1, 2).
