Document Summary

Notes - topic 2: cellular physiology of nerve and muscle (5 lectures) Summarize the main features of the fluid mosaic model of plasma membrane structure making use of the following terms: phospholipid bilayer, hydrophilic, hydrophobic. The plasma membrane separates the intracellular fluid within cells and the extracellular fluid. The fluid mosaic model outside the cells. Model depicts the plasma membrane as an exceedingly thin (7-10 nm) structure composed of a lipid bilayer, lipid molecules with protein molecules plugged in . The lipid bilayer forms the basic fabric of the membrane. Each phospholipid molecule has a polar head that is charged and is loving) and an uncharged nonpolar tail and is. This self-orienting property of phospholipids encourages the membrane to self-assemble and reseal when torn. Associate functions with each of the following plasma membrane components: peripheral proteins, integral membrane proteins, cytoskeleton, glycocalyx, cholesterol. The plasma membrane bristles with proteins that allow it to communicate with its environment.
