Chemical Coordination and Integration

Adrenalin hormone is responsible for the action, as adrenalin hormone is known as 3F hormone. 

Moulting hormone (ecdysone) is secreted by prothoracic gland. These glands are paired, bilateral sheet of cells in the thorax. In Periplaneta, this endocrine gland is X-shaped. This gland is stimulated by prothoracicotropic hormone. Ecdysone, by causing transformation from larval to pupal stage, initiates post embryonic growth in insects.

Second messengers are the organic molecules and sometimes the metal ions, acting as intracellular signals, whose production or release usually amplifies a signal such as a hormone, received at the cell surface.
Sodium (Na) is not a second messenger to be discovered.
In addition to cyclic AMP, Cyclic Guanosine Monophosphate (CGMP) functions as a second messenger in certain cases.
Calcium ions (Ca⁺⁺) also act as second messenger in phospholipase  second messenger system.

Adrenaline (epinephrine) is a hormone produced by adrenal medulla and is secreted in great amounts during emotional states. It elevates the glucose level in blood stream (by glucogenesis) which is accompanied by an increase in oxygen consumption, body temperature, heat production. Adrenaline also causes an increase in the flow of blood by dilating the blood vessels.
Insulin regulates the glucose level in blood.
ACTH (Adreno Corticotropic Hormone) is secreted by the anterior pituitary and stimulates the adrenal cortex.
Glucagon is a polypeptide hormone secreted by the alpha cells of islets of langerhans of pancreas. It acts to promote glycogenolysis.

Deoxyribonuclease and ribonuclease are secreted by pancreas. These enzymes act on DNA and RNA and convert them to deoxyribonucleotides and ribonucleotides, respectively. The optimum pH required by pancreatic juice to secrete these enzymes is 7-8 (alkaline).

Almost all secretion by the pituitary gland are controlled by hormonal signal from hypothalamus. The neurohormones are secreted and accumulated by hypothalamus.

Cortisol or hydrocortisone is the principal glucocorticoid hormone (corticosterone is more abundant in some small mammals). It regulates the glucose metabolism and promotes gluconeogenesis, especially during starvation and raises blood pressure. Cortisone is an inactive form of cortisol.

Pancreas are partially exocrine and partially endocrine gland.

Parathyroid hormones are released when the level of ca is less in blood it increases level of ca in the blood while calcitocine hormones reciprocates the effect.

Gonadotropins or gonadotropic hormones are as follows.

(a) Follicle Stimulating Hormone (FSH) : It stimulates growth of ovarian follicles and their secretion of oestrogen in the female and spermatogenesis in the male.

(b) Interstitial Cell Stimulating Hormone (ICSH) : It activates the Leydig's cells of the testis to secrete androgens. In female it stimulates the corpus luteum of the ovary to secrete progesterone. In female ICSH is termed as LH (Luteinizing Hormone).
