SummaryInnervation of the antennal heart, an independent accessory circulatory motor in the head of insects, was investigated in the cockroach Periplaneta americana by use of axonal cobalt filling and transmission electron microscopy. The muscles associated with this organ are innervated by neurones located in a part of the suboesophageal ganglion, generally considered to be formed by the mandibular neuromere. Dorsal unpaired median (DUM) and paired contralateral neurones were stained. The… 
Antennal circulatory organs in Onychophora, Myriapoda and Hexapoda: Functional morphology and evolutionary implications
The evolution of pulsatile antennal circulatory organs in the Neoptera is the result of the association of muscles with the proximal ampullary ends of the antennals, which indicate a derivation from precerebral pharyngeal dilators.
Octopaminergic innervation and a neurohaemal release site in the antennal heart of the locust Schistocerca gregaria
It is concluded that octopamine released from the neurohaemal area is pumped into the antennae and an involvement in the modulation of the antennal sensory sensitivity is discussed.
Antennal ampullary glands of Helicoverpa zea (Lepidoptera: Noctuidae)
An ultrastructural study revealed that the antennal ampullary gland of the corn earworm moth, Helicoverpa zea, is composed of a single type of 40–50 parenchymal cells that produce secretory granules, suggesting that the AAG is an endocrine gland.
The morphology of suboesophageal ganglion cells innervating the nervus corporis cardiaci III of the locust
Staining of the NCC III towards the periphery reveals that the branching pattern of this nerve is extremely variable, and it innervates the retrocerebral glandular complex, the antennal heart and pharyngeal dilator muscles, and has a connection to the frontal ganglion.
Evolutionary morphology of the antennal heart in stick and leaf insects (Phasmatodea) and webspinners (Embioptera) (Insecta: Eukinolabia)
Outgroup comparison indicates that an antennal heart with a M. interampullaris is the plesiomorphic character state among Embioptera and the likely ground pattern of the taxon Eukinolabia, supporting the view that Australembiidae are the sister group of the remaining Embiopters.
A new kind of auxiliary heart in insects: functional morphology and neuronal control of the accessory pulsatile organs of the cricket ovipositor
The circulatory organs of the cricket ovipositor have a unique functional morphology and Rhythm-modulating and rhythm-resetting interneurons are identified in the terminal ganglion.
CCAP and FMRFamide-like peptides accelerate the contraction rate of the antennal accessory pulsatile organs (auxiliary hearts) of mosquitoes
This is the first report demonstrating that hormones of a holometabolous insect modulate the contraction dynamics of an auxiliary heart, and the firstReport that shows that the hormones of any insect accelerate the velocity of hemolymph in the antennal space.


The anatomy and ultrastructure of the antennal circulatory organs in the cockchafer beetle Melolontha melolontha L. (Coleoptera, Scarabaeidae)
The functional type of the antennal circulatory organs in Melolontha is compared to that found in other insects and their histologic structure is interpreted in relation to mechanical and hemodynamical aspects.
Short Communication: Octopamine in a Neurohaemal Area Within the Antennal Heart of the American Cockroach
In the presented paper, octopamine is shown to occur in another neurohaemal area located within the antennal heart of the cockroach, Periplaneta americana.

The antennal circulatory organ of Periplaneta americana and Blaberus craniifer was investigated by light and electron microscopy and diastole was caused simultaneously in both ampullae by the transverse muscle.

The distribution of the ganglia and nerves of the stomatogastric nervous system and the innervation of the extrinsic and intrinsic muscles are described. Median unpaired frontal and hypocerebral
Evidence for octopaminergic modulation of an insect visceral muscle.
The presence ofOctopamine throughout this neural pathway, coupled with the demonstration of octopaminergic modulation of muscular contraction, supports the hypothesis that octopamine serves a physiological role in this visceral system.
