The following discussion summarizes the endocrine systems of five invertebrate phyla and the two invertebrate subphyla of the phylum Chordata, a phylum that also includes Vertebrata, a subphylum to which the backboned animals belong.

ENDOCRINE SYSTEM. 3. Antidiuretic hormone (ADH) and oxytocin are produced in the hypothalamus and transported by axons to the posterior pituitary where they are dumped into the blood. she is exclusively, Endocrinology - . In invertebrates, the endocrine system is often less complex than in vertebrates, but it is still essential for maintaining homeostasis and enabling the animal to respond to changes in its environment. Endocrine systems, also referred to as hormone systems, are found in all mammals, birds, fish, and many other species. 6. Viral infections can induce several physiological changes in the human endocrine system, resulting in cytokine mediated activation of hypothalamo-pituitary-adrenal axis to increase cortisol production, thus . Three neurosecretory centres have been identified in the simple nemertine brain; one centre controls the maturation of the gonads, and all three appear to be involved in osmotic regulation. You can read the details below. Such responses are usually necessitated by changes that can occur as a result of the animal's interactions with its external environment but also can . 2000.
