Mandibles
Name of the organ of sperm delivery of male insects
Aedeagus
outermost of the three major layers of the insect exoskeleton, this is the only layer that is shed during a molt.
Cuticle
term used to describe insect antennae that are elbowed between the first ans second antennal segment
Geniculate
simple eyes of insects that are only used in detecting ligh vs. dark and in establishing circadian rhythems
Ocelli
the external openings of the insect tracheal system
Spiracles
the blind extensions of the digestive tract that filter metabolic waste from the hemolymph and deposit the metabolic waste incorporated with solid food waste.
Malpighian Tubules
Blind, unbranching fluid filled tubes where gas exchange occurs within an insect body
Tracheal system
extensions of the trachea that lack taenidia
Air sacs
the name of the region of the insect digestive system where enzymatic digestion and absorption of nutrients take place.

Mesenteron
Stomodeum- Swallowing, grinding
Proctodeum - anus(poop), water/salt absorption
is the term to describe the insect mouthpart that forms a coiled proboscis consisting of elongated galea with food channel in the middle. Term describes a function.
mosquitos kind
higher fliers-
Siphoning
Piercing/ sucking
sponging
internal projections of the exoskeleton that serve as attachment points for muscles.
Apodeme
the name of the region of male reproductive system that stores mature sperm prior to them being released.
Seminal vesicle
term used to describe insect legs modified for digging.
Fossorial
Describes mouthparts on an insect are oriented parallel to an insects body and point forward.-
Under/Beneath-

Prognathous
Hypognathous
Opisthognathous
the apical-most segment of the insect antennae -
Basal segment-
Between segment
flagellum
Scape
Pedicel
the layer of the arthrodpod exoskeleton that is composed of a single layer of columnar cells.
Epidermis
one of the two insect mouthparts that have structures called palps,
Maxillae or Labium
the total number of body segments the common ancestor of all arthropods is hypothesized to have had.
the number of abdominal segments that underwent tagmosis to form the posterior-most tagma of insects
20
11
the posterior-most of the tagma that an insect exhibits
Abdomen
modified appendages of the last segment of posterior tagma in insects, often filamentous or forceps-like
Cerci
Describe 2 functions of the Hemolymph in insects
Nutrient transfer
Waste management,
Moisten cells

define the term apterous and explain the difference between primitively apterous and secondarily apterous
being wingless.
Primitively apterous means the insect never had wings in its ancesterial heritage.
Secondarily Apterous means that its ancestors had wings, and it lost its wings somewhere in its evolutionary chain.
Internal linings of the Cuticle,
what two internal organs use it-
Intima
Stomodeum, Proctodeum
Contrast the external morphology between insects and a spider.
Insects have different mouthparts,(list types)
Spiders have modified first pair of appendages called chelcercia,
Spiders leg appendages have metatarsus, and insects have pre-tarsus.
Most spiders are unsclerotized and adult insects are.
Describe the journey of a blood cell in the Helmoymph,
Start in hemocoel in the body, as the heart relaxes the otisa open, and hemolymph flows into the heart. The heart is blind and when the muscles compress hydrolic pressure is formed pushing blood anteriorly through in the dorsal vessel to the opened aorta where it travels into the head and the thoracic appendages first, accessory pulsatile organs then pump into the wings/appendages. then back into the hemocoel and collected by the heart again.
Describe the two types of flight and the muscles.
Paleoptera- Direct flight muscles that are only used to power flight, these have terga-sternal muscles which pull down the notum raising the wing tip, and the dorsal-longitudial muscles which pop the notum up pushing the wing tip down. Anisoptera
Neopetra- has indirect and direct muscles. the direct muscles fold the wings back, and the indirect power flight, coleptera
Address all the characteristics of the of Arthropods.
Dorsal Brain and ventral nerve cord exoskeleton made of chitin Bilateral symmetry and an open circulatory system. Arthropods have Hemocoel excretion via anus dioecious
