QUESTION 1 Which of the following is not a vertebrate orexic agent? • Agouti-related peptide • Galanin Anandamide • Melanocyte concentrating hormone CRH QUESTION 2 Invertebrate reproduction • Is affected by a unique class of estrogen-like steroids • Shares absolutely no physiological processes with vertebrates. Is not affected by hormones related to vertebrate hormones. • Is affected by hormones unique to invertebrates QUESTION 3 All invertebrates are oviparous with limited or no parental provisioning. True • False QUESTION 4 Invertebrates likely have the same range of hormones that regulate feeding behavior, but they have not been characterized. • True • False QUESTION 5 Juvenile hormone • Is a unique 21-carbon steroid with addition of linoleic acid. • Inhibits metamorphosis in insects. • Prevents reptiles from transitioning from a juvenile to an adult state. • Directly controls sperm production in crustaceans. QUESTION 6 Anandamide • Is a terpene. • Is an orexic agent in vertebrates. • Binds to a family of receptors which are all 1-TMS receptors coupled to guanylate cyclase. • Also has direct effect within the GI tract. • Has all of the effects listed above. QUESTION 7 Eclosin • Is an example of an invertebrate-specific hormone peptide controlling reproduction. • Inhibits ecdysone release from vertebrate Inka cells. • Is an invertebrate steroid hormone. Binding to its receptor stimulates adenylate cyclase. QUESTION 8 Vertebrate control of ingestion is localized in the • Peripheral ganglia that secret orexic factors in response to the vision, smell, taste, and texture of food. • Stomach Small intestine • Hypothalamic/pituitary axis. QUESTION 9 Through which process are prior invertebrate anatomical structures lost and replaced with new anatomical structures? • Molting • Ecdysis • Metamorphosis • Growth QUESTION 10 Which of the following statements is false? • Many of the hormones that control some aspect of digestion in animals have multiple versions of receptors • Many of the hormones that control some aspect of digestion in animals are part of large peptide hormone families. • Many of the hormones that control some aspect of digestion in animals, share a high degree of structural similarity. • Many of the hormones that control some aspect of digestion in animals are also found in the CNS controlling very different physiology There are at least 75 hormones that control vertebrate digestion and absorption. QUESTION 11 Which of the following accurately described hormonal control of reproduction? • Male vertebrates secrete peptide hormones into seminal fluid that acts as a hormone in females. None of the hormones that regulate invertebrate reproduction are found in vertebrates. 1-methyl-adenine controls invertebrate reproduction but not vertebrate reproduction. No steroid directly or indirectly controls invertebrate reproduction. QUESTION 12 Invertebrate control of ingestion is localized in the • Small intestine • Stomach • Hypothalamic/pituitary axis. Peripheral neurons that secret orexic factors in response to the vision, smell taste and texture of food. Please answer all for review
