    Study Notes

    Connective Tissue

    • The main function of parenchyma in an organ is to perform specific functions of the organ.
    • The stroma of an organ is made up of connective tissue.
    • Connective tissue cells produce two main fibers: collagen and elastic fibers.

    Types of Connective Tissue

    • One type of connective tissue has a gel-like ground substance with fibers and star-shaped cells, known as areolar tissue.

    Ground Substance

    • The main component of ground substance in connective tissue is water.

    Sound Waves

    • Sound waves are mechanical waves.
    • Sound waves require a medium to travel through because they are mechanical waves that transmit energy through the vibration of particles.

    Audible Frequencies

    • Audible frequencies are sound waves with frequencies between 20 Hz and 20,000 Hz.
    • Humans can hear sound waves within this frequency range.

    Ultrasound Frequencies

    • The main application of ultrasound frequencies is in medical imaging and diagnostic techniques.
    • Ultrasound frequencies are above 20,000 Hz.

    Characteristics of Sound Waves

    • The distance from one compression to the next in a sound wave is called the wavelength.
    • Sound waves are mechanical waves that require a medium to travel through.

    Infrasound Frequencies

    • Infrasound frequencies are below 20 Hz.
