Benign paroxysmal positional vertigo (BPPV) is the most common form of vertigo and is characterized by the sensation of motion initiated by sudden head movements or moving the head in a certain direction. This type of vertigo is rarely serious and can be treated. b. Vertigo may also be caused by inflammation within the inner ear (labyrinthitis or vestibular neuritis)‚ which is characterized by the sudden

Clefts of the lip and/or palate (CL/P) affect approximately one out of 600 live births‚ making it among the most common birth defects in the United States (Cleft Palate Foundation‚ 2014). CL/P is a congenital abnormality necessitating numerous medical interventions‚ such as lip‚ palate‚ and or nose reconstruction‚ and behavioral interventions addressing feeding‚ speech‚ and language difficulties from infancy through late adolescence (Lockhart‚ 2003). When parents are faced with serious decisions

“How Does the Body Function?” Do you consider your body a delicate temple‚ and do you give any thoughts to the daily functions it provides for you? Well‚ to name a few‚ the eyes‚ ears and skin play a vital role in our lives‚ and without these precious body parts I believe our life of living free would be limited. Someone once said that “the eyes provide a window to the soul‚ they also provide us with a window to the world.” Our vision starts when you look at an object; the light from

The human body has five senses that keep in touch with what is going on in the external world: touch‚ taste‚ smell‚ sight‚ and hearing. Below I will describe how these senses work. Taste- The tongue is the body part that helps us sense taste. The tongue consists of taste buds (mushroom like projections) which are specific receptors for sense of taste. Each bud contains several cell types in microvilli that project through pores and chemically sense food. Gustatory receptor cells communicate with

Localization of Brain Function Psychologists have found that the brain often shows “localization of function”. This means that different parts of the brain carry out different tasks‚ for example‚ vision‚ voluntary movement and speech. The idea is that not all parts of the brain do the same thing‚ and that each part functions on its own‚ without the aid of other areas of the brain. This may seem obvious‚ but other organs‚ such as the liver‚ do not show localization of function; one part of the liver

Chapter 5 Outline •Sensation is the detection of physical energy from the environment which weencode as neural signals. •When we organize and interpret our sensations‚ it is known as perception •The beginning level of sensory analysis is also known as bottom- up processing •Top-down processing is the information processing guided by higher-level mental processes‚ as when someone constructs perceptions drawing on our experienceand expectations. •Bottom up processing is sensory analysis that begins

fossil confirm? In a Tiktaalik‚ the head is completely free of the shoulders. This feature is shared with mammals‚ including humans. In this way‚ the Tiktaalik fossil confirms the major paleontological prediction that almost all the body parts (ribs‚ ears‚ and wrists) are similar to ours and therefore that we can be traced back to this fish. 3. Explain why Neil Shubin thinks Tiktaalik says something about our own bodies? (in other words – why the Inner Fish title for the book?) Neil Shubin basically

transducer (an insert earphone or headphone) (Bhattacharyya‚ 2015). The waveform response produced is measured by surface electrodes‚ which are usually placed on the mastoid process behind the outer ear and the vertex (top of the head). A ground electrode is placed on the opposite mastoid (opposite outer ear). The amplitude of the signal is averaged and placed against time much like an electroencephalogram (EEG). Each wave represents electrical activity at one or more point along the auditory brainstem
