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. Recently, the first estrogen receptor sequence for an opisthobranch mollusk, the sea hare Aplysia californica, was published. We've updated our privacy policy.

The hermaphroditic gonad of Euhadra secretes testosterone (identical to the vertebrate testosterone), which stimulates formation of a gland that releases a pheromone for influencing mating behaviour. It is now apparent that ecdysone and 20E are the two most predominant members of a family of steroids that possess molting hormone activity. 3. D: The endocrine system regulates water balance by controlling the solute concentration of the blood. The Endocrine System THE SECRETION OF HORMONES DIRECTLY INTO BODY FLUIDS. Growth in Crustaceans Occurs through molting = ecdysis
Stages of molting
Proecdysis - preparation for molting
epidermal cells separate from the old cuticle (apolysis) and divide forming the new exoskeleton
Calcium removed from old exoskeleton
hepatopancreas - release of energy reserves from storage (animal stops feeding)
Ecdysis
shedding of the old exoskeleton
cuticle is soft - rapid uptake of water
Metecdysis
Mineral deposition into the new cuticle
Endocuticle formation
Feeding begins again
New tissue formation follows
Increased DNA and protein synthesis
tissue replaces water
Intermolt
As skeleton and tissue growth nears completion metabolism is shifted to storage of energy reserves into the hepatopancreas
Regulation of many processes is involved
Metabolism
Water /mineral balance
