Geographic tongue is a disease that affects .6% of Americans. The papillae on the tongue is depleted which leads to several symptoms. The causes of outbreak are certain food types and sometimes stress. This disease gets its name because of the appearance when the tongue breaks out into lesions. It appears to look like a map of different countries on the tongue. The treatment for this disease is usually topical creams, antihistamines, and steroids. Life with geographic tongue is difficult but manageable
Development of Dentition Humans have two dentitions in their lifetime, i.e. the primary (deciduous) and secondary (permanent). Each dentition consists of teeth with different shapes, sizes and functions. The classes of teeth developed throughout our life span are: • Incisiform (incisors) - Incisors are the pair of eight teeth directly situated in the front and center of our mouth, i.e. four in each upper and lower jaw. These single-rooted teeth are extremely important since they all have sharp edges
occurs during the ninth to tenth week of development. The cap stage is where further growth of the bud that becomes indented and covers the connective tissue that is called the dental papilla; the cells of the cap are morphodifferentiated into four layers namely the enamel organ (previously dental lamina), dental papilla and dental sac (previously mesenchyme cells). During the cap stage, the growth and differentiation of different tissues involved give rise to distinct function and morphology of the
A healthy 64-year-old male was seen at the College of Southern Nevada’s Dental Hygiene Clinic on April 13, 2016 for a health history assessment, vitals and screening. The patient stated he was “feeling good.” The major reason for his coming to the clinic is to get a cleaning. His last dental visit was in 2014, and his last doctor visit was in March of 2016. He has no health problems and no allergies. He drinks one beer a day. He stated that he has one dental implant since 2000, although, no
development of hair, feathers, teeth, and scales all depend on the same structure. What is it called? (2 points) Dermal papilla How do reptile scales differ from fish scales? (2 points) A reptiles scales are in the epidermis of the skin whereas a fish’s scales are in the dermis of the skin which is located underneath the epidermis. All reptilian scales have a dermal papilla underlying the epidermal part. Compare and contrast rhino horns, antlers, and giraffe horns in terms of contributions by
The purpose of my experiment is to determine whether human hair or animal hair is better at absorbing oil. In order to find this out, the following questions have been researched, how do you clean an oil spill? Why does hair soak up oil? How is the hair used? Does type/color matter? How effective is it? I will have 10 trails, using the same amount of hair and oil each time, the oil will also be mixed with water to duplicate a more accurate oil spill environment. How do you clean an oil spill?
This cycle tends to last anywhere from five to seven years and is shorter for hair on the eyebrows, armpits and pubic area. Inside the bulb of each hair is a component called the dermal papilla which controls the hair growth while the matrix of the hair, which contains a large amount of epidermal cells that rapidly divide, is responsible for the length of the hair. Next is the catagen phase which is characterized as a transition period between
When approaching the topic of hair chemistry, one may think about the question, where does hair come from? Saclike holes called follicles are located all over the human body. At the bottom of these follicles are a cluster of papilla responsible for the growth of hair. As the papilla, otherwise known as hair bulbs reproduce to make new hair cells, the old ones are pushed up towards the surface of the skin causing the hair to grow longer. This may seem like a simple concept to grasp. However, the process
1. Introduction Crime affects all levels of society and leaves a permanent scar in terms of psychological and emotional impact in the memories of the victims and their families in which time cannot erase. In this assault case, there was a violent tussle between the victim and assaulter in the street, as the assaulter had forcefully snatched the victim’s mobile phone. However, the mobile phone was dropped by the assaulter while in a hurry to escape. Hence, in such kind of violent tussle, distinct

The great debate over how the head segments of existing arthropods are aligned was largely dispelled in the late 1990s when the expression domains of Hox genes were first applied to the study of Arthropod evolution. The traditional concept that chelicerates had lost a deuto cerebral segment and that the chelicerae was innervated by the tritocerebrum was overturned when the anterior expression domain of labial, the anteriormost gene of the arthropod Hox cluster, was found to align the chelicerae with
Introduction Acute pancreatitis following endoscopic retrograde cholangiopancreatography (ERCP) appears to be the most frequent major complication, occurring in 1-10% of patients overall, with a mortality rate ranging from 0.2-0.6% and an annual healthcare expenditure cost reaching $150 million in USA alone (1) (2). Several risk factors have been reported to play a role in ERCP-induced pancreatitis; some are patient-related (i.e. sphincter of Oddi dysfunction (SOD), female gender, history of pancreatitis
The gallbladder is inferior and posterior to the liver. The gallbladder and its connecting ducts are referred as the biliary system. The biliary system is involved in the production and transportation of bile2. Bile is produced in the liver and when it is secreted, it flows through the cystic duct to the gallbladder to be stored. The gallbladder is a storage unit for bile. The job of bile is to emulsify fat. Also in the gallbladder, hard deposits of bile can form. Those hard deposits are called gallstones
Group #1 Brian Brown and Patrick Egan Ms. Ong Biology 23 May 2017 Introduction The first step to dissecting a fetal pig is gathering the necessary tools and equipment. Tools include scissors, pins, a tray, probes, blades, and needles. To prepare the pig, rinse it to remove excess preservatives and place in a dissecting tray. Make sure its back is down, showing its stomach. Then, to ensure the pig is stable, tie a piece of string around one wrist, pass the string under the tray, then proceed to
reveals two distinct areas: the cortex- a dark band along the outer border, about one centimeter in thickness, and the inner medulla. The medulla is divided into 8 to 18 cone-shaped masses of tissue named renal pyramids. The apex of each pyramid, the papilla, extends into the renal pelvis, through which urine is released from the kidney tissue. The cortex arches over the bases of the pyramids (cortical arches) and extends down between each pyramid as the renal columns. Urine passes through the body in
Has anyone ever told you to pinch your nose while eating something unappetizing? Or have you ever had to take medicine that tastes bad, so you decided to pinch your nose? If so, the reason why it worked is that what we smell can affect what we taste and how we taste it. Our sense of smell is a significant part of what we taste. We can tell whether or not we like the food just by the way it smells. Some people might wonder, how do we use our nose to smell? How do we use our mouth to taste? What part
that of a human. Before ejaculation a seminal fluid is added by the seminal vesicles, to prevent the sperm from drying out. As for the kidney’s, they consist of a renal cortex with arcuate vessels surrounds the renal medulla of the kidney. The renal papilla at the end of the renal medulla connects to the renal pelvis. Finally, a ureter descends form the kidney to the urinary bladder in both the mink and human.

After a period of 8 weeks, millions of dermal papilla cells develop. Then, they can be injected back into the scalp. They can grow into new hair follicles. The scariest part of this method of treatment is that, an average bald scalp requires approximately 1000 injections for establishing enough new

A nearby gland secretes a mixture of fats called sebum, which keep the hair shiny and waterproof to some extern… At the base of the follicle is the papilla; these cells play essential roles in regulating hair growth, hair cycle, and the size of the resultant hair. Hair is structured in three basic layers. Packed dead cells surrounding these structures are the cuticular layers of the hair. In the center of these structures lies the medullar canal, which is
Figure 1 http://johnnydissidence.wordpress.com/tag/lung-capillaries/ During internal respiration, energy, known as ATP, is also released. This is used in many reactions within the cells. Energy needed by the body is stored in food and the process of tissue respiration releases this energy. The oxygen oxidises glucose and produces energy. This is known as aerobic respiration. The equation for the oxidation of glucose is; (http://jeshvin.wikispaces.com/Aerobic+and+Anearobic+Respiration) The main
