mouthparts. Insect morphology is the study and description of the physical form of insects. The terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history. Three physical features separate insects from other arthropods: they have a body divided into three regions (called tagmata ...
Standard anatomical terms of location are used to describe unambiguously the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on.
External anatomy. The underside and head of a female spider. Spiders, unlike insects, have only two main body parts (tagmata) instead of three: a fused head and thorax (called a cephalothorax or prosoma) and an abdomen (also called an opisthosoma). The exception to this rule are the assassin spiders in the family Archaeidae, whose cephalothorax ...
Insect physiology includes the physiology and biochemistry of insect organ systems. [1] Although diverse, insects are quite similar in overall design, internally and externally. The insect is made up of three main body regions (tagmata), the head, thorax and abdomen. The head comprises six fused segments with compound eyes, ocelli, antennae and ...
Scutellum (insect anatomy) The scutellum is the posterior portion of either the mesonotum or the metanotum of an insect thorax; however, it is used almost exclusively in the former context, as the metanotum is rather reduced in most insect groups. In the Hemiptera, and some Coleoptera, the scutellum is a small triangular plate behind the ...
Anatomical terms of neuroanatomy. [edit on Wikidata] In anatomy a chiasm is the spot where two structures cross, forming an X-shape (from Greek letter χ, Chi). Examples of chiasms are: A tendinous chiasm, the spot where two tendons cross. For example, the tendon of the flexor digitorum superficialis muscle, and the tendon of the flexor ...
The anatomy of an insect, with the brain (#5) in teal green and ventral nerve cord (#19) in darkblue. Left, a schematic of the Drosophila central nervous system, including the brain and ventral nerve cord. Right, a cross section of the ventral nerve cord, illustrating sensory input and motor output.

Insect cognition. (Redirected from Insect Cognition) A neuron (green and white) in an insect brain (blue) Insect cognition describes the mental capacities and study of those capacities in insects. The field developed from comparative psychology where early studies focused more on animal behavior. [1]
