Reflex Essays

Patellar Reflex The Patellar Reflex is tested by tapping the patellar tendon right below the kneecap, with a small hammer. When a doctor or nurse raps the tendon, the patient immediately kicks their leg out. The quick knee jerk reflex occurs within the spinal cord. The reflex indicates that a section of the spinal cord, and the nerves extending from it are working properly (Staff, 2007). The doctor tests the patient for the patellar reflex to ensure that there are no problems within the spinal

PHYSIOLOGY Physiological implications The swallowing reflex Laryngeal mask airway insertion is highly successful as a blind technique as it utilizes the normal existing physiological mechanism of swallowing to follow the natural curve and the direction of the upper airway; the inserting finger imitating the tongue’s action in swallowing food. However, swallowing reflex itself must be suppressed for the insertion and then tolerance of the laryngeal mask airway cuff in the pharynx

Theory of Cognitive Development The cognitive theory of development is the human intelligence enhancement of an individual throughout their life-span. There are four stages that are involved in the intellectual development of an individual during his or her life. Complexity and abstraction are evident with increase throughout the cognitive development theory of any normal person. The four stages of the cognitive development theory comprise of sensorimotor, preoperational, concrete operational, and

INTRO/BACKGROUND Chronic Traumatic Encephalopathy, a neurodegenerative condition in which an individual may experience executive dysfunction, impaired memory, depression, apathy, poor impulse control, suicidal tendencies, and ultimately dementia, has come to attention in recent years (Baugh et al. 2012). Currently the disease is not diagnosable until the individual has passed away and symptoms often mimic those of other neurodegenerative conditions. With that being said, CTE is a problem that

The results from this lab are consistent with what is expected from a healthy subject. The use of the tendon hammer elicited a reflex of the Achilles tendon. When comparing the stretch reflex with the voluntary reflex, the voluntary reflex exhibited a longer latency. The mechanism is that the use of a reflex hammer, tapped on the tendon causes the muscle to stretch, and according to Purves (2008), this evokes excitation of the Ia sensory axons, innervating the muscle spindles. This excitation reaches

Introduction Attachment is the emotional bond between a child and parent. This bond can shape the way in which the child's emotional and social development can phase out throughout it’s lifetime. Both attachment and temperament have shown robust associations with children’s peer functioning (Berlin et al,, 2008.) Early attachment within the child's life has an impact on the developing brain, which can result in lasting effects at a neuronal level (Schore, 1994.) Of course the importance of attachment

Introduction At the beginning of our lives we are born to create a relationship with our love ones, it depends on our parent to provide us with love and warmth to develop a positive bounding relationship. The purpose of the paper is to reflect which attachment style was utilized by my parents during my childhood and which type of attachment style I identify more during my adulthood. The four types of attachment styles that will be discussed are avoidant attachment, secure attachment, disorganized

The dry mouth reflex was first described by Cannon (1937). When areas of the oral mucosa become dry, mucosal receptors trigger the dry mouth reflex, which results in stimulation of saliva secretion. Dehydration of oral mucosa may also trigger thirst through stimulation of tactile receptors (Hirsch, 2015; John E. Hall & Guyton, 2006). Patients with xerostomia may wake up at night feeling the urge to drink (Bots, et al., 2004)The conjunctival epithelium consists of a non-keratinized, two to five cell

(d)When the subject holds the book, the leg’s movement increases. Part 2: Achilles Reflex Hypothesis: The hammer tapping the Achilles tendon will cause the foot to jerk towards the plantar surface. (e)The toes being to move outwards and heel moves inwards. Part 3:Babinski Reflex (f)Inside-curling toes. Infants exhibit the reverse reflex; their toes typically point outward rather than inside. Part 4:Pupillary reflex (g)The eye that was closed had a larger pupil than they eye that was open. (h) The

30. Price Why? Because that makes this 1080p camera (with 8-megapixel stills) just as expensive as the Hero4 Silver, a camera that shoots in higher resolution (2.7K and low frame rate 4K) has an LCD touchscreen, among other flagship features. Then there's the Hero+ LCD, which costs $100 less than the Session, but has similar shooting modes (1080p at 60fps video, and 8MP stills). 31. Advantages 32. DISPLAY The narrow Lcd on the GoPro Hero 4 Session is not for display what is being captured but rather

Fundus Camera Reticle Setup (Mydriatic) An often overlooked and critical step in obtaining sharp images is to set your reticle. The reticle is the adjustable viewfinder crosshairs and is unique to each operator’s eye visual acuity. To adjust, place a white piece of paper in front of the camera (alternatively, you can use the camera lens cap on), raise the illumination light to highest and while looking through the viewfinder, turn the eyepiece clockwise and counter-clockwise until crosshairs are

Focus. Click Click! FLASH! From the ginormous cameras that people used to use, to the cameras we have today, we’ve gotten a pretty clear understanding that they’ve not only gotten smaller, but they’ve gotten better, and more precise. The movements and ideas that a camera lens provides is magnificent. The cost however, can be insane. Way back in the 1800s, cameras sold for about $10 (even though back then, the equivalent of $10 was worth about $225). Today, a high end camera sells for $1000+, which

Camcorders are one of today’s greatest advancements in technology. Not only do we get to record everyday things but he can do it in outstanding resolutions. GoPro hasn’t been around as long as some of its competitors like Canon, Sony and JCV, but it has advances to the top when it comes to the camcorder market. Only 11 Years ago GoPro was a startup Company. In 2012 Nic Woodman (creatorof GoPro) and Foxconn came to an agreement. Foxconn invested a total of $200 million dollars to a company that has

What are the benefits of a wide angle and why choose one? What situations can they use? Begin because I will answer all these questions for you. A wide-angle lens as its name suggests is just a lens that can capture a wider area than a standard zoom lens, and this gives us great advantages when you take these an image of something or a scene that does not can simply not be pressed into a normal image with a standard lens. One of the main advantages of a wide-angle lens is that you can achieve as

In 1975, an employee of Kodak created the first digital camera from scrap and a single cassette tape. Prior to this invention, photographs were taken using film cameras. Before, photographs were stored on film rather than memory cards. Eventually, the digital format dominated the photography industry. The innovation of the digital camera changed the costs of photography and the way photographs were taken. The Advanced Photo System (APS) was first introduced in 1996 by Kodak under the brand name

“Photography is the only language that can be understood anywhere in the world.” – Bruno Barbey. Photography has been around since the 1800’s (National Geographic Photography 202). Photography involves a variety of skills and contains many different rules and settings (Photo Basics #1: Introduction and Exposure- Improve Photography 1) The basic tools of photography would be a DSLR camera or any camera that one can adjust the settings: ISO, shutter speed, and aperture. Other objects involved would

Terrain, Edie Marshall’s installation of 1000 lushly worked oil paintings, is a record of a road trip through the Great Plains of North America. Over the duration of the trip, made in 2013, Marshall took over 1500 photos on her iPhone. Randomly shooting images on impulse, most of the photos are landscapes taken from the passenger seat of the moving car, though shots also include excursions into towns, cities, historic sites, an aquarium, hiking trails, parks, and roadside vistas. Upon returning

While the majority of these structures promote amplification of sound, the muscles of the middle ear actually serve to protect hearing from damage caused by loud sounds. The tensor tympani and stapedius muscle work together to activate the acoustic reflex when needed. The tensor tympani and the stapedius muscle serve to “increase resonant frequency of the middle ear to protect the inner ear from high sound pressure levels”(Pau, Punke, Zehlicke, Dressler, & Sievert, 2005). The stapedius muscle
