The defense glands in the dorsal prothorax are an important autapomorphic trait of stick insects (Phasmatodea). Here, we study the functional anatomy and neuronal innervation of the defense glands in Anisomorpha paromalus (Westwood, 1859) (Pseudophasmatinae), a species which sprays its defense secretions when disturbed or attacked. We use a neuroanatomical approach to identify the nerves innervating the gland muscles and the motoneurons with axons in the different nerves. The defense gland is…

Neurons of self-defence: neuronal innervation of the exocrine defence glands in stick insects
TLDR
Axonal tracing shows a very complex innervation pattern of the defence glands of Phasmatodea which contains different neurons in different nerves from two adjacent body segments, and some evolutionary changes are notable in a conserved neuronal network.
Motoneurons, DUM cells, and sensory neurons in an insect thoracic ganglion: A tracing study in the stick insect Carausius morosus
TLDR
The general neuroanatomical layout of motoneurons matches the general orthopteran pattern and numbers and details of their structure by far exceed previously published data.

TLDR
The anatomical separation of the various sensory plexuses is indicative of functional localization within the ganglion and is interpreted as indicating a flow of information from labial receptors signalling head and mouthpart movement to neurons involved in salivation and head movement.
A comparative study of neck muscle motor neurons in a cricket and a locust
TLDR
It is suggested that neck muscle function be described in terms of “behavioural units of action”, as several muscles share the same motor neurons.
Serial homologies of the motor neurons of the dorsal intersegmental muscles of the cockroach, Periplaneta americana (L.)
The types and locations of serially homologous motor neurons of the dorsal muscles in the cockroach Periplaneta americana remain rather constant regardless of the various adaptations of their muscles
Functional morphology and neuronal innervation of the prothoracic defence gland in Timema
TLDR
The hypothesis that in euphasmids, the muscular part of the gland evolved from the dorsal longitudinal neck muscles in all Polyneoptera also innervate the defence glands in phasmids is supported.
Motor supply of the dorsal longitudinal muscles II: Comparison of motoneurone sets in Tracheata
TLDR
The results support the idea that the structure of MNs in the largest present taxon of Insecta, the Dicondylia, is conserved irrespective of crucial changes in the periphery (e.g. primarily apterygote vs oteryGote).
Motor supply of the dorsal longitudinal muscles, I: homonomy and ontogeny of the motoneurones in locusts (Insecta, Caelifera)
TLDR
This study of muscles and motoneurones forming identifiable, reiterated neuromuscular units can serve as a segmental matrix for a comparative study comprising other phylogenetic groups of the Tracheata.
Neural mechanism underlying behavior in the locust Schistocerca gregaria. 3. Topography of limb motorneurons in the metathoracic ganglion.
TLDR
There is no relation between location in the ganglion and the muscle innervated, but locomotor motorneurons are clustered togethers in anterior, ventral, and lateral pockets.
