Middle ear

Hearing is a complex process where thousands of tiny hair cells, located in the cochlea of the ear, convert vibrations of sound waves into electrical nerve pulses. These pulses are understood by the brain to be what a person hears as sound. Hearing loss can occur throughout any part of the ear, and in varying degrees of severity. As hearing loss can affect a child’s ability to develop speech, language, and social skills, it is important to identify any signs and symptoms early in the child’s…

Human hearing is a delicate thing, and the ears are always at risk from suffering hearing damage from high volume levels. Concerts are a major reason for damage to the ears, but only if a person attends without hearing protection. Simply putting in a set of earplugs can significantly reduce your chances of sustaining hearing loss at a concert. Damage prevention is so easy, yet 28 million Americans still suffer from deterioration of their hearing as they get older.1 Lack of public awareness is to…

Dr. Grijalva, a lot of her patients seem to go in because they cannot hear well and it’s all due to occlusion of the middle ear because of ear wax. Although it sounds like an easy fix, I do not know if I would be comfortable with the sight of an ear canal full of cerumen and cu tip fibers. Her suggestion for this problem is to tell her patients not to use cu tips to clean their ears since they actually do the opposite of that, they only help push back the cerumen instead of cleaning it out.…

other sounds. Tinnitus is caused by prolonged exposure to loud sounds. Carpenters, pilots, rock musicians, street-repair workers, landscapers, and soldiers are among those whose jobs put them at risk of loud sounds. The treatment for this is to have ear wax removed, treating a blood vessel condition, or changing your medications. Tinnitus is when a person hears sounds like ringing, buzzing, hissing, chirping, whistling, or other sounds. It can be an extremely loud or quiet ringing, buzzing,…

sound as the ear drums move from the sound pressure. Then, this vibration is transformed into electrical impulses, which are sent to the brain. The transformation of the electrical impulse occurs inside the outer, the middle and the inner parts of the ears. The outer ear is called the external sound-gathering part of the ear. Its function is to gather sound energy and focuses it on the eardrum. The middle ear, an air-filled chamber serves as an amplifier of vibration. The inner ear is where the…

Understanding the difference between hearing and listening is the key to understanding how your brain works. From my understanding, there are four modes of hearing and listening when experiencing music. These four modes are known under the term called Quatre écoute, which is French for ‘Four listening’. Ouir, the first term is when you are capable of hearing but we are not paying attention to the sound. Entendre is when we are aware of the sound, ready to listen to it. Ecouter is when you are…

1. The pinna or auricle directs sound waves into the auditory canal. The eardrum vibrates according to frequency. Vibration transmitted to malleus then incus and then stapes of the middle ear. When the stapes vibrate, the membrane of the oval window is pushed in and out. This created the fluid pressure in the perilymph. Pressure waves enter the Scala vestibule then Scala tympani and then round window. This is where the walls become deformed in Scala vestibule and Scala tympani. Pressure…

Focus Objectives 1. Develop at least two (2) complete nursing diagnoses related to medication administration. Impaired Oral Mucous Membrane related to Medication side effects as evidenced by dry mouth and difficulty swallowing. (546) Risk for Aspiration related to impaired swallowing. (67) Impaired Tissue Integrity related to Excess fluid volume as evidenced by damaged tissue surrounding the subcutaneous area. Risk for Infection related to tissue destruction. 2. Identify the six rights of…

around in order to get to where the ball had been hit. In order to do this my brain uses neurons to transmit signals to my body that allows me to make quick motions. Sensory neurons send messages from my muscles and sensory organs, like my eyes and ears, to my brain and spinal cord. My brain then processes that message and sends a response back to my muscles via motor neurons. If, for instance, one of my teammates is heading for the ball the same time I am and we are about to collide, my brain…

Many Americans now drink bottled water exclusively. However, there are good reasons to stick with tap water. Bottled water varies greatly in purify and chemical composition. Some brands are quite healthy, whereas, others have been shown to contain dangerous levels of mercury, bacteria,…
