Mandibular Glands Secrete JH-like compounds - morphogens methyl farnesoate farnesoic acid Responsible for juvenile characteristics Presence results in retention of juvenile characterisitcs However actions are not totally clear. Many hormones are secreted by ductless endocrine glands.Obtain raw materials from and secrete hormones directly into the bloodstream.Exocrine glands have ducts for discharging secretions onto a free surface.Sweat glands, salivary glands, enzyme-secreting glands in the digestive tract.Hormones convey information via the bloodstream to target cells throughout the body.Pheromones carry messages outside the body to other individuals.Three major classes of molecules function as hormones in vertebrates:Proteins and peptidesAmines derived from amino acids- pituitary, parathyroid, heart, stomach, liver, and kidneysSteroids - GONADS, The hypothalamus regulates the neuroendocrine system, maintaining homeostasis in the body.The hypothalamus can use motor nerves to send short-lived electrical messages or hormones to send chemical messages with a longer duration.The hypothalamus produces seven different releasing hormones that travel to the pituitary gland.Each releasing hormone stimulates the pituitary to release a corresponding hormone which travels to an endocrine gland and causes it to start producing a particular endocrine hormone.A stalk links the pituitary to the hypothalamus, which controls release of pituitary hormones. she is exclusively, Endocrinology - .

With more emphasis being placed on research in invertebrate systems, new neuropeptides are being discovered initially in these animals, and subsequently in vertebrates. THE ENDOCRINE SYSTEM Members of this hormone family are collectively called the ecdysteroids. 32. They are allatotropins and allatostatins, respectively. The hormones of endocrine system act as chemical messengers that regulate different body functions such as growth, metabolism, and reproduction.

The neurohemal organ of insects may have an endocrine portion (like the vertebrate adenohypophysis), and hormones or neurohormones released from these organs may stimulate other endocrine glands as well as nonendocrine targets. Now customize the name of a clipboard to store your clips. Consequently, it is not surprising that regulation of the above mentioned processes by their endocrine systems is considerably more variable than in vertebrates, which comprise only part of a single phylum, the Chordata.
