IV. Реферирование текста. Направлено на формирование компетенции ок-5 Hard Palate, Soft Palate and Pharynx

The hard palate forms the roof of the mouth and is covered with keratinized epithelium. Peripherally it is covered with mucoperiosteum continuous with the attached gingival, and attached firmly to the underlying bone. More centrally, in the angle between the palatine and alveolar processes of the maxilla, it is separated from the bone by intervening connective tissue containing blood vessels and nerves. Further centrally and in the midline, the epithelium is again tightly bound down to the underlying bone, which is sometimes raised in the midline as a midline palatal torus of variable size.

In the midline, behind the central incisor teeth lies the incisive papilla, an oval prominence covering the incisal fossa and marking the entry into the mouth of the nasopalatine nerves. Just distal to the incisive papilla there are a variable number of roughly parallel irregular raised folds of mucoperiosteum, the palatal rugae. Further posteriorly, marking the junction of hard and soft palate, lie two small indentations, one on either side of the midline. These are the foveae palatini, where the ducts of two small clusters of salivary glands open into the mouth.

The soft palate is covered with stratified squamous epithelium and divides the oropharynx from the nasopharynx. It terminates distally in a short muscular projection, the uvula. By contact with the posterior wall of the pharynx it regulates the flow of air through the mouth and nose when breathing and speaking.

Laterally the side of the pharynx is marked by two arches. The pharyngeal tonsil is part of a ring of lymphoid tissue, the other parts of which are the lingual tonsil, found on the posterior third of the tongue, and the adenoids, a collection of lymph tissue found in the midline of the posterior wall of the nasopharynx.

Make a summary of the text according to the plan:

a) structures forming the hard palate and attached to it;

b) structure and functions of the soft palate;

c) structures of the pharynx.

IV. Устная речь. Направлено на формирование компетенции ок-6.

1 A student prepared a scheme of the oral cavity but forgot to subscribe the names of the structures. Correct his mistake: give the names of the structures marked by the numbers and describe their position in the oral cavity.

2. Discuss the role and the main purpose of the skull and the oral cavity structures: Eg. – the skull – serves as a framework for the head, protects the brain; etc.
