Based on Sherry’s health history, the examiner decided to perform vital signs and focused physical examination of the eyes and its associated systems. Therefore, the examiner performed a physical exam of head, ears, eyes, nose and throat (HEENT). Like other parts of the physical exam, it begins with inspection, and then proceeds to palpation (Bickley & Szilagyi, 2013). After taking Sherry’s health history, her Vital signs were taken in order to find out if there is any change in her baseline,…

• The nasal cavity makes up the main external opening of the mammalian respiratory system. The nasal cavity is lined with a mucous membrane composed of stratified squamous epithelium tissue. As air gets into the nasal cavity, hairs filter out any impurities or sticks to the mucous membrane. The mucous membrane cells secrete almost 1 liter per day, which moistens the air that is inspired. This mucous membrane is affluent in blood vessels; they warm the air when it goes into the nasal cavity. •…

Introduction The immune system is a collection of cells, tissues and molecules that protect our body from toxins and microbes in the environment. It serves as our defense against molecules that our body does not recognize as its own. This system contains two divisions: the innate immune system and adaptive immune system. Both systems differ in the types of cells produced and the time and length in mounting a response. Inflammatory bowel disease is a chronic inflammatory disease including…

LASIK surgery has been around since the 1990s and over the past two and a half decades, it has become one of the most popular elective surgeries in the world. Surgeons have been working diligently to perfect this surgery and although it is not quite there yet, they have made significant gains in lessening side effects and improving outcomes. These articles contain information about LASIK surgery; including some history, procedure techniques, complications, and patient outcomes. These articles…

In many cases bees have been labeled a nuisance. To some people, especially people who are allergic to bees, these flying insects are no help; yet, in most cases they are essential to the survival of flowering plants or angiosperms. They complete the reproduction cycle of these plants and without them some plants would not have a successful pollination. Besides beekeepers, and other jobs where work relates to bees, these important creatures go unnoticed. Including bees “insect pollinators merit…

Surfactant Agents I. Definitions a. Surfactant: A surface-active agent that lowers surface tension i. Examples 1. soap 2. detergent b. Surface Tension: Force caused by attraction between like molecules that occurs at liquid-gas interfaces and that holds the liquid surface intact i. Units of Measure: dynes/centimeter (dyn/cm) 1. the force required to cause a 1 cm rupture in the surface film ii. a droplet forms because a liquid’s molecules are more attracted to each other than the surrounding…

Lens Fiber Differentiation and its effects on certain organelles. This writing exercise analyzes two separate but related scientific articles, “The fate of the Golgi Apparatus and the Endoplasmic reticulum During Lens Fiber Cell Differentiation” and “Coincident Loss of Mitochondria and Nuclei During Lens Fiber Cell Differentiation” both which analyze and study Lens Fiber Differentiation. The writing assignment will be based on four sections:(1) Background of the research (2) Methods used…

Overview Communication is the basis for all primate social behavior. Primates communicate using a variety of modalities including olfaction, vision, and audition. While primate communication is an extensively researched topic, not all modalities have received the same amount of research. Acoustic communication has been the most often studied, followed by visual and then olfactory (Semple & Higham, 2013). Typically primates are considered visual animals and several species have the ability to…

Cancer Medicine (Oncology) Cancer cells arise from different normal cells, thus when the normal cells become abnormal, it allows the cancer cells to grow out of control. Cancers can start almost anywhere in the human body, it can occur in any tissue and at any time of life, but mostly, elders have the highest risk. Cancers are called neoplasm because neoplasm is new growths that arise from normal tissue. Furthermore, there are two different characteristics of neoplasm: benign and…
