Entomology - External Anatomy questions with
verified answers
Aedeagus Ans✓✓✓ Reproductive organ of male insects through which
they secrete sperm from the testes during copulation
Apodeme Ans✓✓✓ Sclerotised invaginations of the insect cuticle to
which muscles can attach (all muscles attach to elements of the
exoskeleton)
Cibarium Ans✓✓✓ The 'mouth', a food cavity
Clypeus Ans✓✓✓ Broad plate at the front of an insect's head.
Coxa Ans✓✓✓ The first segment closest to the body of an insect leg
(number 1)
Direct flight muscles Ans✓✓✓ Wings are raised by contraction of
muscles attached to the base of the wing inside the pivot point (right at
the base) and then wings are brought down by a contraction of muscles
that attach to the wing outside of the pivot point (further down) Eg -
dragonflies and cockroaches.
Dorsal-longitudinal flight muscles Ans✓✓✓ Aysnchronous control
depends almost entirely on these indirect flight muscles. When the
nervous system sends a "start" signal, the dorsal-longitudinal and
, dorsal-ventral muscles begin contracting autonomously, each in
response to stretching by the other.
Dorsal-ventral flight muscles Ans✓✓✓ "indirect flight muscles"
because have no direct contact with the wings. When the nervous
system sends a "start" signal, the dorsal-longitudinal and dorsal-ventral
muscles begin contracting autonomously, each in response to
stretching by the other.
Endocuticle Ans✓✓✓ The inner layer of the chitinous cuticle
Epicuticle Ans✓✓✓ The outermost layer of cuticle of an arthropod
exoskeleton. (So, endocuticle, exocuticle and then epicuticle)
Epidermis Ans✓✓✓ Outer layer of cells covering an organism
Exocuticle Ans✓✓✓ The outer layer of the chitinous exoskeleton
cuticle of an insect
Femur Ans✓✓✓ The third segment of the leg, between the trochanter
and the tibia (Grasshoppers and locusts have enlarged hind femora
with powerful muscles)
Frons Ans✓✓✓ Front part of the head capsule, below the top two
ocelli
