Document Summary
Cc seq, hd(hypothesize and diagnose) invertebrate pathways and hormones. Cc seq, hd vertebrate pathways and hormones. Stimulus response stimulus: simple endocrine pathways. Stimulus endocrine cells hormone bloodstream target cells response: simple neuroendocrine pathways. Stimulus sensory neuron neurosecretory cell hormone . In presence of high jh, ecdysteroid stimulates an increase in size + molting. At each molt amount of jh decreases (iii) (iv) when jh [ ] is low, pupa forms. Vertebrate endocrine control: hypothalamus, region of brain that produces neurohormones, link between nervous + endocrine systems, 2 modes of actions, produces releasing hormones (rh) + inhibiting hormones (ih) (1) into pituitary portal vein. Bathes anterior lobe of pituitary (2) stimulate or inhibit the release of specific hormones from specific cells w/in anterior pituitary: produces . Adh (antidiuretic hormone) + oxytocin (1) peptides (2) produced by cell bodies of neurons in hypothalamus. Stored in vesicles in axon terminals until neuron is stimulated.
