Match these examples to the correct type of signaling Estradiol released into the blood stream, acts on the pituitary cells A. Paracrine signaling Oxytocin produced in hypothalamic neurons, released from axons into B. Endocrine signaling the blood stream in the posterior hypothalamus C. Neuroendocrine signaling Epithelial cells in arterioles release nitric oxide that causes relaxation of the adjacent smooth muscle cells D. Autocrine Insulin released from the pancreas into the blood, acting on liver cells to simulate glucose uptake Release of cytokines by a macrophage, with cytokines acting on that macrophage to stimulate its immune function

Match the following types of cell signaling to the descriptions provided. Juxtacrine, Autocrine, Autocrine and Juxtacrine, Autocrine and Paracrine, Paracrine and Endocrine, Autocrine and Paracrine and Endocrine and Juxtacrine, or Endocrine -Utilizes soluble signals - Uses local soluble mediators - Same cell produces and receives signal - Uses cell surface receptors - Requires long-lived signal - Uses membrane bound signal molecules

1) What is the difference between endocrine and paracrine signaling? Provide an example of each. 2) What are the three parts of a cell signaling pathway? (See Figure below) EXTRACELLULAR CYTOPLASM Step 1: FLUID Plasma membrane Step 2: Receptor Step 3: Signal transduction pathway Activation cellular response Release molecules in & signal transduction pathway Signal molecule 3) Based on your understanding of the cell signaling receptors, match the type of signaling molecule (ligand) with the appropriate receptor. a. Insulin (protein hormone) b. Acetylcholine neurotransmitter c. Odorant d. Vitamin D (steroid hormone) 6 protein-linked receptor Ion channel receptor Protein kinase receptor Intracellular receptor 4) Second messenger molecules like calcium and cAMP can move through gap junctions into adjacent cells to help coordinate/synchronize cellular responses within a tissue: a. True b. False

Many signals. Match the characteristic (a-i) with the appropriate hormone $(1-6)$ (a) Secreted by adipose tissue (b) Stimulates liver gluconeogenesis (c) GPCR pathway (d) Satiety signal (e) Enhances insulin secretion (f) Secreted by the pancreas during a fast (g) Secreted after a meal (h) Stimulates glycogen synthesis (i) Missing in type 1 diabetes 1. leptin 2. adiponectin 3. GLP-1 4. CCK 5. insulin 6. glucagon
