Cells Flashcards
Hypotonic
More dilute than cells, cells plump up or lyse.
Desmosomes
Anchoring Junctions
Gap Junctions
Communicating junctions, allow molecules to pass through.
ECM (Extracellular Matrix)
Most abundant material, jellylike substance composed of proteins & polysaccharides.
Cell Junction
Allow neighboring cells to adhere & communicate, inhibit or aid movement between the cell.
Intermediate filaments
Mechanical strength to the cells.
Contact signaling
Come Together. It happens when two cells in your body “talk” to each other by touching.
Hypertonic
Higher concentration of nonpenetrating solutes.
Nucleus
Control center and contains the instructions to build nearly all body’s protein.
Microfilaments
Defines the shape of the cell.
Membrane Proteins
Allows communication with its environment, responsible for specialized membrane function.
Cilia (Nose)
Whiplike, motile cellular extensions that occur on the exposed surfaces of certain cells.
ECF (Extracellular Fluid)
Includes interstitial fluid, blood plasma, cerebrospinal fluid.
Membrane Lipids
Form the fabric of the membrane (polar hydrophilic head, non polar hydrophilic tail).
Extracellular
Outside the cell
Pinocytosis
Water eating
Cellular Secretion
Substances that aid in digestion (gastric fluid) or act as lubricants (saliva).
Tonicity
Refers to the ability of a solution to change the shape of cells by altering the cells ; internal water volume.
Microtubules
Provide support & structure to the cytoplasm of the cell.
Ribosome
Site of Protein Synthesis
Cells
Smallest unit of life.
Chemical signaling
Use chemicals to communicate.
Phagocytosis
Cell eating/ Debri eating
Tight Junction
No enters and exit
Microvilli (Tummy)
Tiny, finger-like extensions of the plasma membrane that project from an exposed cell surface.
Isotonic
Have the same concentration / equal of nonpenetrating solutes .
Plasma Membrane
Selectively permeable barrier.
Extracellular Membrane
Substances contributing to body mass are found outside of the cells.
Intracellular
Inside the cell
Cytoplasm
Intracellular fluid packed with Organelles.
