Oropharynx: the oropharynx occupies the area behind the oral cavity, which extends from the uvula to the level of the hyoid bone. Its boundaries are: anteriorly, the mouth through the isthmus faucium, laterally, is the palatine tonsil, between the palatoglossal arch and the palatopharyngeal arch. The anterior wall consists of the base of the tongue and the epiglottic vallecula; the lateral wall is made up of the tonsil, tonsillar fossa, and tonsillar (faucial) pillars; the superior wall consists of the inferior surface of the soft palate and the uvula1’2. Groups of lymphoid tissue in the mucosa of the pharynx surround the entrance of the throat in a ring-like positioning, known as Waldeyer 's Ring. They are three groups: -1- Palatine tonsils, the most protruding groups in the ring and form recognizable masses, (also known as the tonsils), -2- Pharyngeal tonsil (also known as the "adenoids"), and the -3- Lingual tonsils2’3. Histologically, there are three characteristic features distinguish the tonsils from each other: their position, type of the epithelium and the number of crypts3.
Tonsil Position Type of epithelium Crypts
Palatine In the lateral walls of the oral part of the pharynx. Stratified squamous non-keratinising. 10-20 in number.
Pharyngeal In the midline on the roof of the nasopharynx. Ciliated pseudostratified columnar epithelium, as well as some patches of stratified squamous epithelium. Numerous folds of pharyngeal epithelium, not real crypts.
Lingual At
The nasal septum divides the medially into the right and left portion. The nasal septum separates the cranial cavity by the cribriform plate of the ethmoid bone and by the oral cavity by the hand palate. Passageways called the superior, middle and inferior meatuses are the nasal conchae or turbinate bone that curl out from the lateral walls of the nasal cavity on each side. Nasal conchae support the mucous membranes that line the nasal cavity that help increase the surface area. The upper posterior portion of the nasal cavity is slit like and lines and contains the factory receptors that give use the sense of smell. The rest of the cavity conducts air to and from the nasopharynx.
The palate, or roof of the mouth has two parts; anterior and a posterior portion. The anterior is the firm tissue closest to the teeth to the middle of the roof of the mouth. The hard palate is in white firm center in the top of the mouth. The wave like tissue is the palatine rugae leading to the incisive papilla which is the small bulge at the beginning of the palate (Martini). The posterior portion of the palate is a looser more yellow and light pink color. The soft palate goes from the middle of the uvula that hangs from the posterior palate.
Henry VIII was a king of England from 1509 to 1547. He kept his power because he was able to reciprocate some of the suggestions that Niccoló Machiavelli expressed in his book, “The Prince.” Although there were many similarities in how Henry VIII ruled England and what Machiavelli explains in “The Prince,” Henry VIII did deviate from Machiavelli’s tips.
1. Oral cavity, pharynx, (must also include accessory organs such as salivary glands, tongue, and teeth)
➢ After leaving the pharynx, air enters the ;larynx, where two pairs of ligaments, together with the mucosa covering them, forms the vestibular and vocal folds. These folds help prevent foreign particles, including food, from entering the lower respiratory system.
The Epiglottis is a flexible flap of cartilage at the top end of the larynx which covers the air only passage and stops food going into the trachea when we swallow. The
Folds running from the mouth to the chin and/or the nose to the mouth (melolabial and nasolabial folds)
Consist of oral cavity, esophagus, gallbladder, liver, stomach, duodenum, pancreas, colon, cecum, appendix, jejunum, and rectum.
Also known as the throat. It is as opening surrounded by muscle that leads on to the larynx
These are pyramidal-shaped areas which are also separated from each other by membranes. There are about 10 of them in each lung. Each segment receives its own blood supply and air supply.
Tonsillitis is inflammation of the tonsils, with particular reference to the palatine tonsils , two ovoid bodies of about 2,5 - 3,5 cm in length and two in width consist of lymphoid tissue and placed at the sides of the throat, immediately behind and above the base of the tongue. The tonsils are exposed to inflammation, usually viral, bacterial, more rarely, resulting in enlargement of themselves and with referred pain in the throat and in some cases ear.
Imagine after years of being dead, a human body is found and all that is really left of them is their teeth. Why? It may be because of the way they took care of their teeth while they were alive and the precaution methods they were educated about. Educating people about oral health is really important because teeth are the strongest bone in our body and they even preserve the most after we pass away, this means it is an essential factor to knowing how to protect them from getting a disease and keeping them as long as possible. Most patients are not aware of diseases in dentistry. Educating the older and the young generation will help to care for their oral health.
Mouth: The mouth has many functions, which include, “Ingestion, taste and other sensory responses to food, mastication, chemical digestion, swallowing, speech, and respiration” (Saladin, p 958). The mouth has many anatomical landmarks, which include, cheeks, lips, palate, tongue, oral fissure, fauces, and squamous epithelium (Saladin, p 958). The mouth is located at the bottom center of the face, and is controlled by the mandible.

Organization for Economic Co-operation and Development (OECD) International Network on Financial Education (INFE) has defined financial literacy as “a combination of awareness, knowledge, skill, attitude and behaviour necessary to make sound financial decisions and ultimately achieve individual financial wellbeing”. Bhushan and Medury (2013) stated that financial literacy helps individuals to improve their level of understanding of financial matters which enables them to process financial information and make informed decisions about personal finance. It was found that well-functional financial markets depend on participants making informed decisions (Agarwalla et al., 2012). Moreover, Bhushan and Medury (2013) found that financial education empowers individuals to take their financial decisions in a better and effective way.
