Full list of words from this list:

  2. hertz
    unit of frequency with a periodic interval of one second
    Since sound is vibrations propagating through a medium such as air, the detection of these vibrations, that is the sense of the hearing, is a mechanical sense because these vibrations are mechanically conducted from the eardrum through a series of tiny bones to hair-like fibers in the inner ear which detect mechanical motion of the fibers within a range of about 20 to 20,000 hertz,[4] with substantial variation between individuals.
  3. hair follicle

    Some neurons in the nose are specialized to detect pheromones.[citation needed]

    Balance, equilibrioception, or vestibular sense is the sense which allows an organism to sense body movement, direction, and acceleration, and to attain and maintain postural equilibrium and balance.
