Structure Of The Ear How It Sounds - 1433 Words

Structure of the Ear (How we translate sounds) To understand how deafness occurs, we first need to understand how people regularly hear. The ear can be split into three divisions: the external ear, the middle ear, and the inner ear. The external ear collects sound waves and sends the waves down to the ear canal which then vibrate the eardrum. The middle ear carries sound waves to the inner ear and also contains the smallest bones in the body. The middle ear also contains the Eustachian tube which connects the middle ear to the middle throat. The inner ear converts these intercepted sound waves into neural signals and also contains the cochlea. There are other things in the ear besides these three divisions such as the organ of corti which contains the cells responsible for the hearing hair cells. There are two types of these hair cells in the ear: inner and outer hair cells. Both of these cells work within the cochlea and have a stereocilia, an organelle of hair cells, but the outer hair cells function specifically in the cochlea. The outer hair cells contain the stereocilia at the top of the cell and the nucleus at the bottom. When the stereocilia bends, an electromotive response occurs which changes the cell length with every sound wave. Also in the ear is the auditory nerve. The auditory nerve has fibers that rest below the hair cells and pass the sound wave signals to the brain. The hair cells also have sensory cells which sit on top of the basilar membrane.

The organs which are primary and absolutely crucial for this kind of sensory actions are: the eye and the ear. They are connected to the brain, and they are highly influenced by it to interpret what can be seen and heard. The different parts of the eye are responsible for the body to absorb light and perception objects in the true color, intensity and detail. While, t he ear’s components are important for detect, perceive sounds and controllingRead MoreAuditory System Essay621 Words   |  3 Pagesorgan is being used. If this information were auditory, the ear would convert sound waves in the air into electrical impulses that would further be interpreted by the brain as sound. A sound wave first enters the pinna, the fleshy part of the ear on the outside of the body. It then travels through the external auditory canal where it then meets the eardrum, a thin membrane in the outer ear. The eardrum then vibrates in response to the sound wave. What we hear will depend on the wavelength and frequencyRead MoreQuestions On The Human Ear1598 Words   |  7 Pageshuman ear is very complex in structure and fragile through growth and development. The structure of an ear is made of three parts; the outer ear, middle ear, and inner ear. In order to hear, sound waves pass through the outer ear, causing vibrations at the eardrum inside the middle ea r. From here, the vibrations are amplified and pass through fluid-like substance in a snail-shaped structure called the cochlea, located in the inner ear. The cochlea has tiny hairs that translate and send sound vibrationsRead MorePsy 340 Essay765 Words   |  4 PagesUniversity of Phoenix Material Neurological Structures and Functions Worksheet Short-Answer Essays 1.

The ear converts sound waves in the air, to nerve impulses which are sent to the brain, where the brain interprets them as sounds instead of vibrations.

Using Peled ( 1993 ) - 1476 Words

Qualitative Studies Edleson only relied upon one sample for the Qualitative Study in this article using Peled (1993, (1998). The sample included 14 preadolescent children and 12 battered women which relied upon the measure of â€Å"6 semi-structured interviews with each child with an average of 4 – 1 hour interviews per child. Mothers were interviewed one time† (Edleson, 1999, p.859). Communicating Findings Comparison Group In Fantuzzo, et al. (1991), there appears to be a lack of base line in which to rely upon the facts, due to the exclusion of what one would consider the social norms. Fantuzzo, et al. should have had a baseline in which to rely giving their study more standing. In regards to Carlson (1991), the degree of age and maturity appears to be more stable and within a comprehensive age span for a determination than it did in Fantuzzo (Edleson, 1999, p.847). The study group consisted of all teenagers. Although the age was appropriate for a comparative study, out of the 50 samples only 12 had witnessed and 25 who had never experienced abuse or domestic violence for this study. Hughes (1988) showed higher levels of behavior problems in the witnesses comparison children.(Edleson 1999, p.848) In this sample, the mothers were the primary samples and not the subject children due to influence of the parent the children possibly were hindered due to influence of the attending parent.

Rumination is a key antecedent for depressive outcomes as underlying cognitive effects interfere with adaptive thought processes in several ways (Lavender Watkins, 2004; Lyubomirsky Nolen-Hoeksema, 1993, 1995; Lyubomirsky et al., 1998;Read MoreCounseling Abused Women7410 Words   |  30 Pagesprofessional treatment.
