Document Summary
Frequency number of sound waves or cycles per second (hz = one cycle per second) Amplitude vertical size of the sound waves (decibels db) Sound localization ability to notice location of sound due to timing difference in sound neurotransmitters wave reception in ear. Two types of hearing loss: conduction deafness problems involving the mechanical system that transmits sound waves to the cochlea, nerve deafness caused by damaged receptors within the inner ear, or damage to the auditory nerve. Taste (gustation) and smell (olfaction) are sensitive to chemical molecules rather than energy. Taste buds chemical receptors along edges and back surface of tongue: consists of bitter, sour, salty, and sweet receptors. Receptors of smell are long cells that project through the lining of the upper part of the nasal cavity and the mucous membrane. Pheromes chemical signals found in natural body scents: menstrual synchrony tendency of women who live together to have similar menstrual cycles.
