Cell Membrane Information http://upload.wikimedia.org/wikipedia/commons/thumb/b/b6/Cell_membrane_detailed_diagram.svg/800px-Cell_membrane_detailed_diagram.svg.png

The cell membrane is probably the most important part of the cell. It holds the cell together and protects it. It regulates homeostasis which gives the cell the best possible living conditions. The cell membrane regulates what goes in and out of the cell. The cell membrane is very flexible and moves freely. The cell membrane is made of a phospholipid bilayer, which has hydropholic heads which love water and hydrophobic tails which hate water.

Interesting Facts 1. The cell membrane is very thin ranging from 3-10nm thick. 2. It is comprised of a glycerol/phosphate head and a fatty acid tail. This allows nonpolar molecules to pass through while repelling polar molecules. 3.Cholesterol holds the membrane together and keeps the cell moving freely.

BipolarDisorder Caused by abnormalities in the cell membrane cause it isnt controlling the the proper amount of nutrients that is needed for homeostasis. "Controlled, double-blind trials show multinutrient combinations of vitamins, minerals, orthomolecules, herbals, and the omega-3 fatty acids EPA and DHA to be effective monotherapy. The molecular action of lithium and valproate converge with nutrients on the level of the cell membrane and its molecular signal transduction systems. This emergent, unified rationale presages effective integrative management of bipolar disorder." http://findarticles.com/p/articles/mi_m0FDN/is_2_9/ai_n6112778
