Endocrine Flashcards
paired glands in the anterior part of the body that produces hormones
endocrine system
internal secretion produced in endocrine glands;
complex chemical compounds that is carried by the bloodstream and exercises a specific physiological reaction
hormones
list the types of endocrine organs
neurosecretory cells of the body;
specialized endocrine glands
group of modified nerve cells in the dorsal part of the protocerebrum that produces: peptide hormones, prothoracicotrophic hormone and bursicon
neurosecretory cells of the brain
activates the thoracic glands
peptide hormone
also known as the brain hormone
prothoracicotropic hormone
from the thoracic ganglia;
control the hardening and darkening of the cuticle;
regulates tanning (initiates transfer of tyrosine to the hemocytes)
bursicon
a pair of small bodies lying on each side of the aorta;
responsible for discharging neurosecretory materials into the hemolymph;
includes swollen endings of neurosecretory axons and neurosecretory cells
corpora cardiaca
small ovoid bodies associated with the stomodaeal ganglion;
produces juvenile hormone
corpora allata
control the metamorphosis and regulation of reproductive development;
antagonizes ecdysone;
inhibit appearance of adult character;
ensures that molting gives rise to the normal sequence of nymphal and larval instars
juvenile hormone
becomes less active towards the juvenile life of insects;
and resume activity for full development of ovaries anand accessory reproductive accessory glands
Corpora allata
a pair of diffused glands at the back fo the head or in the thorax;
produces ecdysone
thoracic / prothoracic glands
molting hormones;
induces molting in immature insects;
initiates tanning;
antagonizes the effect of vittelogenesis
ecdysone
the stimulatory action of the juvenile hormone
vittelogenesis
involved in pupariation;
from the peripheral nerve endings;
involved in the production of DOPA
anterior segment refraction factor (ARF)
