What is the general function of chemical messengers?
They are used for cellular respiration.
They regulate growth, development, and metabolism.
They break down nutrients in the digestive system.
They protect the body from diseases.
Which type of chemical messenger is produced by the central nervous system for quick action on muscle cells?
Hormones
Local Chemical Messengers
Neurotransmitters
Pheromones
What is the source and transmission of hormones in the body?
They are released into the bloodstream by neurons to cause changes.
They are released on the surface of animals to cause changes in another animal of the same species.
They are released into the bloodstream by endocrine glands.
They alter physiological conditions in nearby structures.
What is the function of pheromones?
They cause asexual reproduction in Platyhelminthes.
They are involved in the development of Cnidarians.
They are released on the surface of an animal to cause changes in another animal of the same species.
They help in shedding the cuticle in Nematodes.
Which invertebrate uses chemical messengers for asexual reproduction, regeneration, and gamete maturation?
Cnidarians
Platyhelminthes
Nematodes
None of the above
What do mollusks regulate through their chemical messengers?
Shell growth and gamete production
Heart rate, actions of kidneys, metabolism
Molting and color changes
Gamete development
Which type of glands lack ducts and secrete chemicals directly into the bloodstream?
Exocrine Glands
Endocrine Glands
Pineal Gland
Pituitary Gland
What is the function of the pineal gland in fish?
Regulates water, ions, blood pressure, and smooth muscle contraction
Secretes prolactin which begins reproductive migration
Produces neuroeptides that affect pigmentation and inhibit reproductive development
Secretes chemical into ducts leading to body cavities or surface
What does the pituitary gland secrete in fish that begins reproductive migration?
Neuroeptides
Prolactin
Water and ions
Chemicals into body cavities
Which hormone is secreted by the thyroid and helps regulate metabolism as well as calcium levels in Hawaiian Goby and Salmon?
Chromaffin
Prolactin
Thyroxine and triiodothyronine
Glucocorticoids
What do the adrenal glands secrete to help prepare for stressful situations by increasing blood pressure, heart rate, and glucose levels?
Thyroxine
Chromaffin
Oxytocin
Melatonin
What is the function of prolactin in birds?
Regulates sleep/hibernation/estivation cycles
Develops parental behaviors, nesting, and brooding
Regulates water balance and urine production
Affects many parts to encourage cell division and protein synthesis
Which hormone in mammals is responsible for the production of red blood cells?
Glucocorticoids
Parathyroid Hormone
Erythropoietin
Melatonin
Which group of animals would not use hormones to initiate migration?
Birds
Mammals
Fish
Amphibians
What is the function of the calcitonin?
