Describe how neurons communicate. To do this you must address: resting membrane potential; graded potentials; IPSPs; EPSPs; the role of sodium, potassium and calcium; generation of an action potential; inotropic vs metabutropic receptors; why is an AP only one direction; how are neurotransmitters released; continuous vs saltatory conduction; spatial vs temporal summation.

Along with the kidneys, the ureters, bladder, and urethra make up the urinary system. match each function or description to the appropriate structure.

You have a solution that contains phospholipid vesicles in a test tube. these vesicles have phospholipid bilayers, but do not contain any membrane transporters. you add a number of different molecules to the solution, and wait a period of time for them to equilibrate. if you could measure the concentration of each molecule, for which of the following would you expect to measure equal concentrations inside and outside of the vesicles? assume for this question that the overall osmolarity inside and outside the vesicles is the same (that is, there is no appreciable diffusion of water across the membrane). (select two answers) an amino acid with a hydrophobic side-chain a small non-polar molecule a negatively charged ion a small polar molecule a small lipid hormone
