Cochlea

Questions 1. What problem does the visual system face when perceiving depth? Hint: think about proximal and distal stimuli. (5 pt.) When our visual system perceives depth it uses distal stimulus and proximal stimulus. This is problematic because the distal stimulus and/ or environmental stimuli are three dimensional but the proximal stimuli hitting your retina are two-dimensional Therefore, in order to perceive depth your brain needs to interpret the two-dimensional stimuli as three dimensional…

outer ear from the middle ear. When sound reached the middle ear, the ossicles, which are the tiniest and most delicate bones in one’s body, transfer the initial sounds to vibrations and send them to the inner ear. The inner ear is the home of the cochlea, which changes the sounds into neurological signals for the brain and the auditory nerves. When sound is originally made, it must go through the entire process before the brain can register that specific sound. When one of the steps of the…

At 2:49 pm on April 15, 2013, two improvised explosive devices (IEDs) detonated near the finish line of the 117th Boston Marathon, immediately killing three bystanders and injuring hundreds (Singh et al., 2016). Prior to the rise in terrorist attacks, most explosive injuries occurred in combat zones. Each blast injury comes with different injuries or a combination of injuries depending on the severity. The injuries have several negative effects on the body. Certain radiologic imaging can be used…

(CSF). The purpose of the (MRI) is to rule out abnormal physical conditions and of the head and possibly the middle ear for Meniere’s disease. Audiometric testing (hearing) electronystagmography (ENG), test measures the inner ear pressure in the cochlea. This is the small shaped bone structure in the inner ear that controls one balance. The (ENG) will show if there is an increase in fluid pressure. Inner ear pressure is one of the main criteria’s for diagnosing Menere’s disease. The…

Down-Syndrome Do you ever see other people and wonder why they act and look so differently? Their is a genetic disorder by the name of Down-Syndrome. Down-Syndrome is a condition in which a person has 47 chromosomes while others have 46 it is also the most common chromosome condition. People with this disorder may have the facial features of flat face, small nose, upward slant eyes, enlarged tongue and may appear shorter than others. Kids with Down-Syndrome tend to grow at a slower rate. You…

American Sign Language (ASL) is made up of complex hand signals most commonly used to communicate with the deaf or hard of hearing. Unlike all other languages, ASL does not use or need neither speech nor hearing. Therefor, it is the most effective way to communicate with the deaf. Everything is made up of elements. Even the smallest bones in the human body, which are located in the ear and are vital for your ability to hear. People have been evolving form the beginning of time. Humans were…

and females lose hearing at the same level. The life structures of the ear comprises of the external ear, the center ear and the inward ear. During the time spent listening to misfortune there is a winding formed bone in the inward ear called the cochlea, which is lined with little hair cells. Sound waves are transmitted by the external ear, through the center ear, to the internal ear. In the internal ear, the sound wave weight moves the hair cells, which then send messages to the mind, through…

which bring cognitions. The eye sees all in reflections, dispersed views with lights and colours that enter through the cornea into the retina. The ear sees the hearing, the sounds of all melodies, a wave which moves in the wind, just within the cochlea which vibrates. The nose sees the smell, from the air, an odor which comes from the substance, through the mucous…

drum (tympanic membrane). Sound waves enter the auditory canal, touching the tympanic membrane making it vibrate. The vibrations; passing other parts, eventually stimulates the hair cells (auditory receptors). These hair cells are located in the cochlea of the ear containing fluid. Results of hearing loss can be due to injuries to the ear canal, loss of the auditory receptors because of exposure to loud noises and wear and tear. When having a hearing loss, most people turn to hearing aids that…

Osteogenesis Imperfecta (OI) is a genetic disorder that affects the formation of bones. The term Osteogenesis Imperfecta literally means imperfect bone formation. People with OI have bones that break easily, usually caused by a mild trauma or no cause at all. Multiple fractures are common with this disease since bones are weak. Although, in severe cases fracture of bones can occur before birth. This disease is caused by defective connective tissue and the lack of Type One Collagen. There are…
