Homework Answers
2. Autocrine means cell produced the substance that has an effect on the cell by which it is secreted.
3. Paracrine is a hormone which has effect only in the vicinity of the gland secreting it.
4. Chemical messenger molecules carried in the blood by endocrine glands are called hormones where it can affect the target organs.
5. Chemical messenger is released from the axon terminal of a neuron and directly stimulates other cells are called neurotransmitters.
6. ADH or vasopressin is released by posterior pituitary glands. It is a kind of neurohormone. The neurohormones in most mammals include oxytocin and vasopressin, both of which are produced in the hypothalamic region of the brain and secreted into the blood by the neurohypophysis.
7. Peptide hormones are lipophilic
8. True.
9. True.
10. False. Adenyl cyclase converts ATP into cAMP.
11. False because lipophilic ligands bind to cell membrane receptors, not to the nuclear receptors.
12. True. Eicosanoids for inflammation, fever, blood clotting etc and steroids derived from cholesterol eg sex hormones.
13. True.
