inner ear

Receptors that can be found in the mouth include: chemoreceptors, mechanoreceptors, thermoreceptors, and nociceptors. These are receptors that detects chemical stimuli, either molecules or ions dissolved in liquids.

How are the olfactory receptors activated? The olfactory tracts transduce signals to the hypothalamus. Odorants dissolve in the mucus and bind to receptors. Odorants dissolve in the mucus and bind to receptors.

Pharyngotympanic tube The eustachian tube is a canal that connects the middle ear to the nasopharynx, which consists of the upper throat and the back of the nasal cavity. It controls the pressure within the middle ear, making it equal with the air pressure outside the body.

The ear canal is a hollow tube that carries the sound waves to the eardrum. The sound wave hits the eardrum, causing it to vibrate. The eardrum transmits these vibrations into the inner ear where they are amplified.

The visible part of the ear, pinna collects sound, travels through the auditory canal. Soundwave reaches the eardrum tympanic memebrane. Travels through the three tiny bones called the hammer, anvil, and stirrup. Sound travels to the cochlea which has fluid and tiny hair-like structures called cilia.

Sound waves entering the ear travel through the external auditory canal before striking the eardrum and causing it to vibrate. The eardrum is connected to the malleus, one of three small bones of the middle ear. Also called the hammer, it transmits sound vibrations to the incus, which passes them to the stapes.

The auricle (pinna) is the visible portion of the outer ear. It collects sound waves and channels them into the ear canal (external auditory meatus), where the sound is amplified. The sound waves then travel toward a flexible, oval membrane at the end of the ear canal called the eardrum, or tympanic membrane.

Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.

As particles continue to displace one another with mechanical vibrations, the disturbance is transported throughout the medium. These particle-to-particle, mechanical vibrations of sound conductance qualify sound waves as mechanical waves.

Sound waves are LONGITUDINAL waves; they cause a disturbance in a medium characterized by compressions and rarefactions. Sound waves are MECHANICAL waves; they require a medium. You just studied 29 terms!

Acoustic instruments, Electrical instruments, Living beings like animals and birds using their vocal cords, Man-made sources like machines, any vibration caused by wind are five sources of sound.

Sound waves do die out after a while. When this vibrational energy is absorbed by objects in space, the energy of the wave starts reducing ultimately making is so low that the resulting sound is inaudible, and the sound finally dies out.
