Trace in words, a sound signal from the outside traveling to the hair cells in the cochlea.
1. Trace in words, a sound signal from outside to the hair cells in the cochlea 2. Trace in words, a light signal from outside to the rods/cones in the retina 3. Trace in words, an odor signal from outside to the Olfactory cortex (Brain/Temporal lobe) 4. Trace in words, a blood cell traveling in the circulatory systemExplanation / Answer
To start with, know the three main divisions of the ear/auditory system
As the sound waves travel through the ear, they are changed into electrical impulses which are carried by auditory nerve to the brain.
outer ear-waves enter the outer ear, and travel through the external auditory canal and strike the eardrum -------------->Eardrum: vibrates upon encountering the sound waves and sends these vibrations to the three bones of the middle ear----->Middle ear: The malleus bone of the middle ear vibrates first and sends the vibrations to the other two bones (incus and stapes).As the stapes bone vibrates, it pushes the oval window (opening leading from middle ear to inner ear )in and out.These bones amplify the sound vibrations and send to cochlea------> inner ear/cochlea: it is a fluid-filled organ of the inner ear which is divided into upper and the lower part by a structure called as the basilar membrane.Vibrations cause the fluid inside the cochlea to ripple and a travelling wave is formed which travels through the basilar membrane.-------->cochlea/ Basilar membrane: basilar membrane of the cochlea consists of a sensitive receptor organ called Corti which consists of hair cells which transmit the wave by moving up and down, generating an electrical signal which is carried by auditory nerve to the brain
