postÂ·synÂ·apÂ·tic memÂ·brane. That part of the plasma membrane of a neuron or muscle fiber with which an axon terminal forms a synaptic junction. postsynaptic membrane. the excitable membrane of the DENDRITE next to the AXON at a synapse, that receives the nerve impulse.
Turbidity is the measure of relative clarity of a liquid. It is an optical characteristic of water and is an expression of the amount of light that is scattered by material in the water when a light is shined through the water sample. The higher the intensity of scattered light, the higher the turbidity. Material that causes water to be turbid include clay, silt, finely divided inorganic and organic matter, algae, soluble colored organic compounds, and plankton and other microscopic organisms. Turbidity makes water cloudy or opaque.
Turbidites are sedimentary rocks formations that result from turbidity currents. Turbidity currents are essentially underwater avalanches or landslides of sand or mud.The debris deposited as a result of these subaqueous flows typically forms a graded bed of sediment built up at the base of a submarine slope.urbidity currents are rapid, underwater avalanches or landslides of sand or mud. What is important is that because of the stirred up sediment that the current contains, its density is greater than water and so it flows down slopes and spreads out on horizontal surfaces at the bottom of the slope.
