TT A&P Cell Term
Thompson A&P Cellular Terminology
| Cell Organelle or Process | Description |
|---|---|
| Cell Membrane | a selectively permeable double layer of phospholipid |
| Cytoplasm | the site of all cell metabolic reactions, contains organelles |
| Nucleus | directs activities of the cell with genetic material |
| Nucleolus | functions to synthesize ribosomes |
| Centrioles | aids in movement of chromosomes during mitosis |
| Ribosomes | functions in protein synthesis, made by nucleolus |
| Rough Endoplasmic Reticulum | functions in protein synthesis, intracellular communication and transport |
| Smooth Endoplasmic Reticulum | functions in lipid synthesis, intracellular communication and transport |
| Golgi apparatus | functions in modification, packaging and transport of protein |
| Lysosomes | digest wastes from cell metabolism and function in autolysis |
| Mitochondria | the site of cellular respiration for energy (ATP) production from the breakdown of glucose using oxygen |
| Microfilaments | smallest protein cytoskeleton |
| Microtubules | larger protein cytoskeleton found with cilia and flagella |
| Cilia | hair-like cell membrane extensions that move substances in cavities |
| Flagella | hair-like cell membrane extension for cell locomotion (sperm is only example in humans) |
| Microvilli | finger-like cell membrane extensions that increase surface area |
| Diffusion | molecules move to equilibrium over time (passive/high to low concentration gradient) |
| Osmosis | diffusion of water through semi-permeable membrane (passive/high to low concentration gradient) |
| Facilitated Diffusion | diffusion with special carrier protein molecule in cell membrane (passive/high to low concentration gradient) |
| Filtration | pressure pushes material through membrane pores (passive/high to low concentration gradient) |
| Active Transport | opposite of facilitated diffusion, uses special carrier protein molecule in cell membrane (active/low to high concentration gradient) |
| Phagocytosis | cell taking in solid particle by vesicle (active/low to high concentration gradient) |
| Pinocytosis | cell taking in liquid by vesicle (active/low to high concentration gradient) |
| Receptor Mediated Endocytosis | special entry into cell with carrier molecule or peripheral protein on cell membrane and vesicle (active/low to high concentration) |
| Exocytosis | expel substances from cell by vesicle (active/low to high concentration) |
