Mechanisms of intercellular communication (i. e. between cells: 1. Gap junction: b. membrane (tunnelling) nanotubes, c. mechanosignals, 2. Direct communication through membrane nanotubes: nanotubes are formed from the plasma membrane. They are longer than gap junctions, and have a larger pore diameter. Discovered in 2004: transfer of nucleic acids, even small organelles, between cells, might be a method of transferring cellular components from stressed to healthy cells. Eating a meal increases the metabolic rate: 2. If you follow appropriate dosage, its fine, if you double the dose can have serious affect on body - raises hr and bp, normal response is that temporarily hr and. Bp go up a little bit - in most it comes back down within a matter of weeks: isn"t dangerous with appropriate dosage in a healthy person, hormones, 1. 2: adh released from neurons released into bloodstream travels to kidneys and reabsorbs water.
