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.
