What is the function of the cell membrane?
The cell membrane regulates the flow of materials into and out of the cell. It acts as a gatekeeper, controlling which substances can enter and exit the cell.

Study Notes
RUQ (8 Organs)
- Duodenum
- Gallbladder
- Liver
- Pancreas
- Stomach
- Right Adrenal Gland
- Right Kidney
- Transverse Colon
RLQ (5 Organs; 3 Repro Organ)
- Appendix
- Ceccum
- Large intestines
- Right Reproductive Organ (ovary, fallopian tube, spermatic cord)
- Right Ureter
Nucleus
- Innermost part of the cell
- Contains genetic material
- Houses DNA
- Contains chromosomes which contain genes
- Genes control cellular structure and function
- Nucleus is sensitive to radiation
- Radiation can cause mutations or gene deletion
Cell Structure and Function
- Cell is the basic living structural and functional unit
- Cell biology/cytology studies cellular structure and function
- Cell division is the process where cells arise from existing cells
- Parts include nucleus, cytoplasm, and cell membrane (plasma membrane)
- Animal cells are 10-30 micrometers in size
Plasma Membrane
- Outer layer of the animal cell
- Gatekeeper of the cell
- Controls the flow of materials in and out of the cell
- Communicates with other cells
- Made up of a lipid bilayer
- 3 layers: Phospholipids (75%), cholesterol (20%), glycolipids (5%)
- Phospholipids have a polar head and nonpolar tails
- Polar heads interact with water (hydrophilic)
- Nonpolar tails do not interact with water (hydrophobic)
- Cholesterol is weakly amphipathic
- Glycolipids have carbohydrate groups
- Has integral proteins embedded in the lipid bilayer
- Many integral proteins are transmembrane proteins
- Glycocalyx (extensive sugar coat) on integral proteins is hydrophilic
Cell Parts and Locations
- Superior - towards the head
- Inferior - away from the head/towards the bottom
- Anterior - front
- Posterior - back
- Ipsilateral - same side
- Contralateral - opposite side
- Proximal - near the point of origin
- Distal - far from the point of origin
Superficial vs Deep
- Superficial - towards the surface (e.g., epidermis)
- Deep - away from the surface (e.g., muscles)
