    Study Notes

    Functions and Characteristics of Tissues

    • Epithelial tissue:
      • Functions: forms boundaries, absorbs and secretes substances, and protects underlying tissues
      • Characteristics: composed of cells laid together in sheets, tightly connected to one another

    Nervous Tissue

    • Functions: integration and communication in the body
    • Characteristics:
      • Composed of neurons and neuroglia
      • Neuroglia support and nourish neurons
      • Dendrites receive signals, axon transmits signals, axon terminal releases neurotransmitters

    Muscle Tissue

    • Types:
      • Skeletal muscle: voluntary, striated, and attached to bones
      • Smooth muscle: involuntary, non-striated, and found in hollow organs
      • Cardiac muscle: involuntary, striated, and found in the heart
    • Functions:
      • Skeletal muscle: moves bones
      • Smooth muscle: aids in the movement of substances
      • Cardiac muscle: pumps blood

    Connective Tissue

    • Functions: supports, protects, and gives structure to other tissues and organs
    • Types:
      • Adipose tissue: stores fat and helps repair damaged tissue
      • Cartilage: avascular and has a gel-like ground substance
    • Components:
      • Matrix: ground substance and fibers
      • Cells: fibroblasts, chondrocytes, and adipocytes

    Nervous Tissue Components

    • Neurons:
      • Dendrites: receive signals
      • Axon: transmits signals
