Auditory system

In this lab, you will investigate the behavior of the human nervous system and make observations of the special senses. Activity 1: Touch Receptors (worth 10 points total) List four sensations detected by the tactile receptors in the skin (1) Temperature (2) Touch (3) Pain (4) Wetness Get a volunteer to touch each of these locations on your body using the same pressure. Close your eyes and rank how sensitive each area is from 1 (low sensitivity) to 5 (high sensitivity). Put your rankings in…

brain will decrease in size at a faster rate because of the lack of auditory stimulation. In other words, the inability to hear well speeds up the rate at which a person ages. This could be due to the natural decrease in size of the auditory cortex of the brain since it isn't able to receive any information from the damaged ears that are causing the hearing loss. Since other parts of the brain work in correlation with the auditory cortex, as it shrinks, they are not used as much, so they shrink…

If you have some hearing problems go to Dr.Karen Mills. She is a Audiologist and a very good one at that she had a lot to say about being an Audiologist she knew everything about it and she got a Doctorate degree in it. She was telling us about how there was three types of hearing loss one being just mechanical hearing loss like too much earwax in your ears then, there was another one like if your eardrum was busted some times it could heal back and seal but other times if the hole was too wide…

Tinnitus is the ringing in the ear, which is an unwanted sound that one can hear. The sounds can be constant or comes and goes, soft or loud, and in one ear or both. There are three ways to distinguish the symptoms of the patient’s tinnitus sound: tonal tinnitus, pulsatile tinnitus, and musical tinnitus. Tonal is a near continuous sound that are affiliated with subjective tinnitus, which is just the normal ringing sound, pulsatile is pulsing sound that one hears from their heartbeat and for some…

I currently have 4.75 senses. Sight. Smell. Taste. Touch. And three-quarters of my hearing. However, the magic number was not always 4.75- it was a bit less. The weeks after my audiologist told me that I lost half my hearing can only be described as utter chaos. I was behind on AP Biology work. Hours were spent with my AP Spanish teacher preparing for aural quizzes. My teachers had grown accustomed to seeing an empty seat where I usually sat because of my frequent doctor appointments. On top…

The Basics of Hearing Loss Hearing loss is a common health condition that affects more than 50 million Americans in the United States. Despite the fact that some of us have ears and have the ability to hear, many do not have a true understanding of the ear and how they work. To truly understand hearing and hearing loss, it helps to know the basics. Having a basic understanding about the function of the ears can help you better collaborate with your physician, and can lead to better hearing…

The topic I will be researching about is middle ear infection. Otitis media also known as middle ear infection is a group of inflammatory disease of the middle ear. The 2 types of infections are acute otitis media and otitis media with effusion. A shorter way to say these infections are AOM and OME. AOM is an infection that usually presents with ear pain. OME is typically not associated with symptoms. Aom affects about 11% of people a year,there is about 325 to 710 million cases. Some of the…

The special senses are hearing, equilibrium, vision, taste, and smell. Hearing is associated with the ear and how the sound waves travel through from external to internal ear. The external layer of the ear consists of the auricle, external acoustic meatus, and the tympanic membrane. Sound enters through the auricle, which carries the sound waves to the external acoustic meatus (i.e. ear canal). The external acoustic meatus in turn carries the sound waves to the tympanic membrane (i.e. eardrum).…

What is hearing loss and deafness? Is it the inability to hear sound? Or is it more than that? The answer will depend on who you ask. With regard to hearing loss, there are three main types. An individual with conductive hearing loss has the inability to hear due to any number of issues stemming from the outer ear. Sound waves are not able to pass from the outer ear to the inner ear, specifically the cochlea (a spiral cavity that looks like a snail shell that receives sound in the form of…
