Nonvisual Sensory System

When a person with normal hearing hears the sound travels along the ear then bounces against the ear drum. The eardrum, the bones inside, and the cochlea vibrate and move thousands of tiny hairs inside the ear. When these hairs move an electrical response occurs. This electrical response goes to the hearing nerve and then it is send to the brain.

Basically how sound travels through the ear is a process of many steps. The sound waves are gathered by the pinna and then funneled into the meatus. Those waves then begin to vibrate the tympanic membrane which in turn hits against the malleus. The ossicle bones then vibrate like a chain reaction. The footplate will hit the oval window which triggers the fluid in the cochlea to move. The movement sways across the different hair cells creating impulses that are sent to the brain through the eighth cranial nerve.

Hearing: Hearing is a sense of sound perception. Hearing involves vibration and the mechanoreceptors located in the inner ear help turn motion into electrical nerve impulses. The sense of hearing is mechanical and this is due to the vibration being mechanically conducted from the eardrum through small bones within the ear. Hair like fibres within the inner ear help detect mechanical motion of the fibres within 20,000 hertz of range. Hearing starts to decline in older age and hearing at high frequency is no longer possible. In some cases hearing becomes so severe that hearing is

The physiology of hearing starts with a vibration that occurs in the air which sends an acoustic signal to the ear drum. The signal is transduced into a mechanical signal that transmits through the inner ear and the cochlear nerve. Finally, the signal is

interpreted by sound receptors on the skin. This is transmitted to the brain for integration before

The middle ear has three ossicles (tiny bones) the hammer, the anvil, and the stirrup that connect the middle ear to the inner ear. When sound enters your middle ear, it causes the ossicles to vibrate. These vibrations then move into the cochlea, which is filled with fluid. When the vibrations move the fluid that is in the cochlea, it stimulates tiny hair cells that respond to different frequencies of sound. After the tiny hair cells are stimulated, they direct the frequencies of sound into the auditory nerve, as nerve impulses. (ASHA 2013)

How Outside Stimuli are affected by the Five SensesAP1 ProjectShelby HardenSo, many things use the 5 senses. Each sense controls something different. Without having one of the five senses, can turn your whole life around. Treasure them all. Each function provokes every step you take in life. Outside stimuli can be received by the five senses which are sight, sound, touch, smell, and taste. Sight is very important to everyday life. Light waves off an object is what lets us see. The brain connects the light wave to memories or what it might be associated with, which then allows us to precept what the object is. This process happens so fast, you never see it coming. The stimuli you get from seeing is the colors the make an object and projects feelings. Sound is precious.

Just like the eyes the ears also have a good amount of layers. The first layer is the outer ear that is made from skin and cartilage, and due to its curvy shape our ears are able to catch the sound. The sound then travels from the outer ear to the tympanic membrane, this membrane forms the eardrum and vibrates in order to respond to sound waves. From the membrane the sound moves to the inner ear, the inner ear has three very small bones. These small bones send the sound information to the brain through the auditory nerve.

Audition is the term used to define hearing, and involves sound waves, which are interpreted by our brains to help us distinguish individual sounds. The process of hearing starts in the outer ear, which sends sound waves to the ear drum. The ear drum vibrates and hits the tiny bones in the middle ears, followed by the stirrup, one of the tiny bones, to hit the oval window of the cochlea. Vibrations from the striking of the oval window cause waves in the fluid in the inner ear to deflect the basilar membrane. Hair cells are bent, then interact with the auditory nerve, followed by neural impulses being passed onto the brain which translate the impulse into information that tells us what sound was just heard.

If an Infrared Light with a wavelength of 750 nm were to be observed by humans, they would not be able to because none of their cone cells are sensitive to this wavelength of light, in a similar manner that the blue cone cells weren’t sensitive to the 600 nm wavelength of light. It is only possible for the human brain to view lights that are absorbed by their photoreceptor cells.

Studies published in Chemosensory Perception show individuals with psychopathic traits may also have a weak sense of smell. The article ‘Psychopaths’ Have An Impaired Sense Of Smell, Study Suggests, which was published in Science Daily, has studies done by Mehmet Mahmut and Richard Stevenson in Australia. Previous research shows that the area of the brain dealing with empathy, something psychopaths do not use, and the olfactory sense are relatively near each other in the frontal cortex. The scientists took 70 non-criminal adults who volunteered for the study and began with assessing each participant’s accuracy and sensitivity to smell. Afterwards, they measured the individuals’ psychopathy levels. They did this by asking a series of questions

The purpose for this experiment was to measure the reaction time for auditory stimuli using a measuring ruler and compare to visual cue. In auditory pathway, once the auditory signals arrive into inner ear, the Cochlear hair cells which is he auditory receptor cells, in the organ of Corti of the inner ear receive the sensory stimuli (Hudspeth 2014). There are two types of cochlear hair cells: the inner hair cell that carry out transmitting the signal to the rest of the auditory pathway, and outer cells that mediate the transmitting of information (Hudspeth 2014). According to (Tong, 2013), the cochlear hair cells or presynaptic neurons synapse with spiral ganglion, which are the first afferent nerve fibers. The basolateral membrane of the

The snail like shape of the cochlear effectively boosts the strength of the vibrations caused by sound, especially for low pitches. When sound waves hit the ear drum, tiny bones in the ear transmit the vibrations to the fluid of the cochlea, where they travel along a tube that winds into a spiral. The tube’s properties gradually change along its length, so the waves grow and then die away, much as an ocean wave travelling towards the shore gets taller and narrower before breaking at the beach.

Explained as simplistically as possible, Visual perception itself is the ability to interpret one 's surrounding environment by, processing information through the eye to the brain. The eye is a sense organ which is part of the sensory system which in turn transmits information about one 's environment to the brain.
