Cell Wall- The cell wall is a rigid structure outside the cell membrane that supports and protects the cell. The cell wall is made of tough cellulose fibers and other materials made by the cell. Analogy- In a restaurant the building itself supports the restaurant. It is often made of wood or concrete. Cell Membrane- The cell membrane is a structure that forms the outer boundary of the cell and allows only certain materials to move into and out of the cell. Food‚ oxygen and water move into

Sample Physiology MCQs 1. Compound action potentials can be graded responses. True 2. The sciatic nerve contains axons of both afferent and efferent neurones. True 3. The absolute refractory period of an action potential is the period after an initial stimulus when it is impossible to evoke another action potential with a second stimulus. True 4. The refractory periods of individual axons are important as they dictate the maximal action potential firing rate of a neuron. True 5. Compound action

CONCENTRATION AND DILUTION Physiology 1‚ Las Positas College Name: In science‚ concentration is a measure of the number of particles (solutes) in a given volume. If one room has 100 people in it‚ and a room of equal size has 50 people‚ one can say that the concentration of people in one room is twice that of the other. Quite simple‚ isn’t it? On a molecular level‚ consider whether you put one lump or two of sugar‚ or no sugar at all‚ in your coffee. If you use two lumps‚ you prefer twice
