Biology: The Cell: 03: Structure - Structure of the Cell Membrane - Medical Animation
MEDICAL ANIMATION TRANSCRIPT: In this video, we will be discussing the structure of the cell membrane. When scientists looked at the selectively permeable cell membrane, they described its structure as a fluid mosaic. You might know that a mosaic is a picture made up of little tiles. Like a mosaic, the cell membrane is made up of different parts as well. The cell membrane has two layers of phospholipids referred to as a lipid bilayer. The lipid bilayer isn't rigid. The phospholipids in it have the ability to move in a flexible wave-like motion. Let's take a closer look at a few phospholipids. The round head portions are hydrophilic, which means they're attracted to water. Both the extracellular fluid, meaning fluid outside the cell, and the cytoplasm inside the cell are mostly made up of water. So, the hydrophilic phospholipid heads of the outer layer will be oriented toward the extracellular fluid. And the heads of the inner layer will be oriented toward the cytoplasm. The phospholipid tails are hydrophobic, which means watery areas withheld them. So they orient toward each other in a direction as far away from the watery content as possible. There are also scattered proteins embedded in the phospholipid layers, some with carbohydrates attached. So, in the fluid mosaic model, the cell membrane is made up of different parts. And these parts make up a flexible boundary around the cell. But how do the majority of substances get in our out of the cell? Some molecules sip through the little spaces in between the phospholipids, which make up the majority of the semi-permeable cell membrane. However, other molecules are too big to fit through the cell membrane this way. So, how do these larger molecules pass through the cell membrane? The molecules move through proteins embedded in the cell membrane, either from the extracellular area into the cell, or from the intracellular area out of the cell. These substances will move through tunnels made up of these proteins. We'll explore how things move through the cell membrane in greater detail separately. [music]

What attorneys say about MLA and The Doe Report:
"A few words about The Doe Report: recently in a brachial plexus injury case, we used an image from The Doe Report to demonstrate the injury. We downloaded the PDF file image, and were amazed at the quality. The hard copies that you sent were even more clear. As well, we could not have been happier when you customized the image and reversed the injury from the left shoulder to the right shoulder, which is where our client's injury was.

The speed and cost-effectiveness of the product made it the perfect tool for our purposes. We will use The Doe Report again in future cases."

"Thank you for the splendid medical-legal art work you did for us in the case of a young girl who was blinded by a bb pellet. As a result of your graphic illustrations of this tragic injury, we were able to persuade the insurance company to increase their initial offer of $75,000.00 to $475,000.00, just short of their policy limits.

We simply wanted you to know how pleased we were with your work which, to repeat, was of superlative character, and to let you know that we would be more than willing to serve as a reference in case you ever need one. Many thanks for an extraordinary and dramatic depiction of a very serious injury which clearly "catapulted" the insurance company's offer to a "full and fair" amount to settle this case."

"We are extremely pleased with the quality of the medical exhibits and the timely manner in which they were provided. I will certainly recommend your company to my business associates who could benefit from your services. Please tell Brian Wilson [Director of Content Development, Senior Medical Illustrator] that he did an exceptional job on these exhibits."

"I wanted to take some time out to let you know what a wonderful job you did with the 'collapsed lung/fractured rib' illustrations. They were both detailed and accurate. My medical expert was comfortable working with them and he spent at least an hour explaining to the jury the anatomy of the lungs, the ribs and the injuries depicted in the illustrations. Needless to say, the jury was riveted to the doctor during his testimony.

The jury returned a verdict for $800,000.00 and I'm sure we would not have done so well if not for the visualizations we were able to put forth with your assistance. Lastly, my special thanks to Alice [Senior Medical Illustrator] who stayed late on Friday night and patiently dealt with my last minute revisions."
