Essays on Cochlea

A. The human cerebral cortex is divided into three main areas: sensory, motor and associated areas (Association Cortex, 2016). Sensory areas belong to the peripheral nervous system. They extend from the spinal cord to the receptor cells located in all parts of the body. The primary function of sensory area to carry impulses from the receptor cells to the brain for interpretation. These impulses can be those of sensations like touch, pain, smell, taste and sight. The motor area or the primary motor cortex is located in the interior part of the brain at the central sulcus. Its pyramidal ...

A. An anticholinergic is a drug used in the treatment of diseases such as asthma, muscular spasms, insomnia and gastrointestinal cramps (Healthline, 2016). The drug is also used with anesthetics as it inhibits the action of parasympathetic nerve impulses by preventing acetylcholine reaching the receptor cells of nerve impulses. This may lead to memory loss, confusion, drowsiness and even sedation. These effects are more pronounced in old-aged people. Loss of muscular strength and fainting is a symptom which could be seen in the patient. Use of anticholinergic drugs is not recommended for patients with conditions like glaucoma, hyperthyroidism, heart ...

In this particular paper, we are going to present the key ideas that have been described by Mr. Protik Majumder in his youtube video ‘Musical Acoustics and Sound Perception’. This lecture of his addresses the dynamics of sound synthesis and in short, Mr. Majumder also explains the semantics of our ability to identify and distinguish one sound from the other. He starts off by plucking a string and showing the audience how a sound wave is created. Using this concept, he describes some key concepts including transverse waves, the energy of the wave and he shows the shape of ...

Cochlear implants are very instrumental in ear care. These developments are enabled by advances in technology; hence, allowing medics to offer the world of sound, music, and speech to people who would otherwise spend their entire or large part of their lives in soundless cocoons. As research indicates, the United States has had more than 30,000 cochlear implants on people across all age groups since 1999 (Ear Surgery Information Center, 2016). However, this eminent success in cochlear implant surgery has not really watered down the discourse surrounding the effects and implications of cochlear implants. Particularly, there has been ...
