Cell & General Cellular Activity

• Muscle and contractile cells: movement
• Epithelial cells: forms ADHESIVE and TIGHT junctions between cells.
• Fibroblast, cells of bone and cartilage: Synthesize and secrete components of the EXTRACELLULAR MATRIX
• Neurons and sensory cells: Convert physical and chemical stimuli into action potentials.
• Cells of digestive glands: Synthesis and secretion of DEGRADATIVE ENZYMES
• Cells of mucous glands: Synthesis and secretion of GLYCOPROTEINS
• Certain cells of the adrenal gland, testis, and ovary: Synthesis and secretion of STEROIDS
• Cells of the kidney and salivary gland ducts: Ion transport
• Macrophages and neutrophils: Intracellular digestion
• Fat cells: Lipid storage
• Cells lining the intestine: Metabolite absorption
• Cell: basic structural and functional unit
• Cell: Smallest living parts of the body
• What is the main function of cells?

  To maintain homeostasis
• If the tight junction is not properly functioning, what will be prone to infection?

  Blood-brain barrier
• What can be seen on the skin and detects changes in TEMPERATURE and shapes of objects being touched?

  Sensory cells
• What can be found in the JOINTS and SYNOVIAL fluids that function for lubrication?

  Glycoproteins
• In case of tissue damage where it cannot repair itself, our body exhibit what?

  Phagocytosis
• Macrophages: tissue monocytes that engulfs foreign materials
