Read the text and be able to answer some questions.

The human teeth are made up of four tissues: the enamel, the dentine, the cementum and the pulp.

The enamel is the white, compact and very hard substance. The enamel covers the exposed parts of the softer underlying dentine. Its function is to protect the tooth against the wear and friction.

The dentine is the chief substance or tissue of the teeth composing the bulk of the tooth and the characteristic form of the tooth. It surrounds the tooth pulp, and is covered by the enamel on the exposed part of the tooth and by the cementum on the part implanted in the jaw. The dentine resembles a bone, but is harder and denser.

The cementum closely resembles in structure an ordinary bone. It covers the dentine beyond the border of the enamel, overlapping it slightly at the gingival line and forming the surface of the root. Its function is to furnish the attachment of the fibres of the periodontal membrane which fastens the tooth to the bone.

The cementum is relatively small in amount in the child but it increases during life.

The pulp is the soft vascular tissue occupying the pulp chamber and the root canals of a tooth, composed of nerves, blood vessels and connective tissue. It is the remain of the formative organ which has given rise to the dentine. The pulp of the tooth is one of the most sensitive structures of the body.

THE SUPPORTING TISSUES

The human teeth are supported on the alveolar and supporting bones,

the periodontal membrane and the gingivae. The alveolar processes of the

maxillary bones grow up around the roots of the teeth, so that the roots
fit into the holes of the bone. The periodontal membrane performs three
functions:

(a) it maintains the teeth in their functional positions through its
suspensory mechanisms;

(b) it takes part in the formation of the bone of its own alveolar walls and of the cementum;

(c) it provides through its tactile sensory mechanisms, for protection against the swallowing of hard, sharp and potentially dangerous materials.

The cement is the layer of a modified bone which encases the whole of the tooth except its crown. It begins at the neck as a very thin layer which slightly overlaps the enamel. From there it is continued increasing in amount towards the apex, which is formed entirely of this substance. It is relatively, small in amount in children, but it increases during life.

The pulp of the tooth is composed of a number of branched fibrous tissue ceils. Their processes form a fine network, which contains numerous blood-vessels, nerves, and lymph vessels. The most superficial of these cells are arranged in the young tooth, lying on the surface of the tooth against the destine; they are known as odontoblasts for they are active in the formation of the dentine.

The vessels of the tooth-pulp are numerous. Fine nerve bundles run through the pulp, the root canals towards the crown of the tooth and some of their fibres enter the odontoblasts Sayer. The alveolar periosteum is a layer of fibrous tissue free from elastic fibre but well supplied both with blood vessels and nerves.

6. Read the text and be ready to answer some questions:

The bones of the face consisting of the mandible and the superior maxillary bones form much of the anterior portion of the face. The superior maxillary bones are closely knit together except the mandible which is movable. The superior maxillary bones, being knit together on the median line of the face, are two in number, and of very irregular form.

They occupy the anterior upper part of the face and consist of a
body and processes. Being the largest bones of the face except the
mandible, they enter into the formation of three cavities, namely: the orbit,
the mouth and the nares.

The body is the central part of the bone. The body is shaped something like a pyramid and exhibits four surfaces, namely: the external or facial, the posterior or zygomatic, the superior or orbital and the internal or palatine.

The facial surface is directed forwards and vertically, the lower border being more protruded than the upper one. This surface presents a depression just above the canine and the first bicuspid teeth. It is called the canine fossa. Above the canine fossa, there is the infra-orbital foramen for the nerve of the same name.

The zygomatic surface is situated posteriorly forming the anterior boundary of the zygomatic fossa. Between it and the facial surface there is a well-developed ridge extending from the molar region to the base of the zygomatic process.

The posterior surface has a bulging called tuberosity. It is connected with the palate bones and bounds the antrum behind. Being perforated by three or four small holes the posterior surface transmits nerves and blood vessels to the molar teeth.

The orbital surface of the superior maxillae forms the greater part of the floor of the orbit.

The superior maxillary bones by their union form the arch of the upper jaw and each bone presents for examination a body and four processes, e.g. zygomatic, frontal, alveolar and palatal.

The superior maxillary bones are the largest of the face except the mandible.

The body is the central part of the bone and has four surfaces.

The external surface is irregularly convex and has the so called "canine fossa".

The nasal surface forms the lateral boundary of the nasal cavity.

At the lower aspect of the zygomatic surface there is the "maxillary tuberosity" and the posterior dental vessels and nerves enter the bone.

The superior face of the bone has the infra-orbital groove, which, passing forwards, becomes canalised and divided into two branches, one terminating in the infra-orbital foramen; whilst the smaller branch transmits the anterior dental nerves and vessels to the front teeth of the upper jaw.

Translate them:

1. The upper part is known to be called the alveolar part.

2. The lower border is known to be the base of the mandible.

4. Read the text and be ready to answer some questions:

The mandible lies below the anterior part of the cranium and is the skeleton of the lower part of the face. It has the body and a pair of flat, broad rami, which stand up from the posterior part of the body.

Each ramus is surmounted by two processes: the anterior is named the coronoid process, and the posterior is the condyloid one. The condyloid process has an articular part called the head.

The right and left halves of the body of the mandible are united
together in the medial plane in front. Their junction is called the
symphysis menti. The halves of the mandible are joined together by
fibrous tissue at birth, but they are fused together into one bone during
the second year. Each half of the body of the mandible has an outer
and inner surface and an upper and a lower border. The surfaces

slope so that the lower border makes a wider arch than the upper border.

The upper pan is known to be called the alveolar part because it is occupied by a row of alveoli, those are the sockets for the teeth. On each side the sockets for the two incisors, the canine and two premolars are single but for the three molars are double, for each mandibular molar has two roots: anterior and posterior. The lower border is known to be the base of the mandible. The outer surface is slightly convex, but has a depression alongside the symphysis below the incisor teeth. The mental foramen is seen on the outer surface of the mandible. The inner surface is convex and concave at different parts. There is a shallow depression called the submandibular fossa.

The mandibular foramen leads into a canal which runs in the substance of the bone and carries the vessels and nerves for the teeth.

The mandible is the only bone of the face which has movement. The temporamandibular joint is known to make a wide range of mandibular motion. This joint consists of two joints on either side of the mandible, which articulates with temporal bones on either side of the head. The mandible serves as the attachment of the elevator muscles which consist of the masseter, temporal and internal pterygoid muscles.

Lesson 11

MOSCOW

Moscow is the capital of Russia its political, economic , commercial and cultural centre. It was founded 8 centuries ago by PrinceYuri Dolgoruky. Historians have accepted the year of 1147 as the start of Moscow's history. Gradually the city became more and more powerful. In the 13th century Moscow was the centre of the struggle of Russian lands for the liberation from the tartar yoke. In the 16th century under Ivan the Terrible Moscow became the capital of the new united state. Though Peter the Great moved the capital to St. Petersburg in 1712 . Moscow remained the heart of Russia. That is why it became the main target of Napoleon's attack. Three-quarters of the city was destroyed by fire during Napoleo n's occupation but by the mid-19th century Moscow had been completely restored. After the October revolution Moscow became the capital again.

Now Moscow is one of the largest cities in Europe. Its total area is about nine
hundred square kilometres (ancient Moscow occupied the territory of the present-day
Kremlin). The population of the city is over 12 million , plus some three million guests
coming annually.

Moscow is one of the most beautiful cities in the world. The heart of Moscow is Red Square. It has more historic associations than any other place in Moscow. On the territory of the Kremlin you can sее old cathedrals , the Bell Tower of Ivan the Great the Palace of Congresses , the Tzar-Cannon and the Tzar-Bell.

There are a lot of beautiful palaces old mansions, cathedrals, churches and monuments in Moscow. This year marks a significant national event for Muscovites and all Russian citizens - the jubilee celebration of Moscow's 850th anniversary. In 1994 the jubilee was approved by Presidential decree. Since then an intensive and widespread programme of restoration has enabled a rebirth for the City of Moscow. The recriation of the magnificent Christ the Saviour Cathedral is in full swing. Red Square's Kazansky Cathedral, Voskresenskv Gate and the Iverskaya Chapel have been restored. The majestic Monument of Victory on Poklonnava Hill has added to the capital's beauty. Across the city, churches, theatres , railway terminals anu monuments of history. Culture and architecture have been renovated in preparation for this sigatificant and historical year.

Moscow is famous for its museums and theatres. There are more than museums in Moscow. The largest museums are the Pushkin Museum of Fine Arts and the State Tretyakov Gallery. The Tretyakov Art Gallery has the richest collection of Russian and Soviet fine arts. Its 50 rooms are hung with pictures of marvelous beauty.

Other unique museums in Moscow include the All-Russian Museum of Folk Arts the Andrei Rublev Museum of Early Russian Art , Alexei Bakhrushin Theatre Museum Mikhail Glinka Museum of Musical Culture and many others.

There are many theatres in Moscow The Bolshoi Theatre enjoys the greates popularity. Grand and majestic building is a masterpiece of Moscow classicism. Its history is part of the history of Russian operatic and ballet art. F.Chaliapin . L .Sobinov. and many other famous singers appeared on its stage. The Bolshoi Ballet has won world fame.

The Maly Theatre is just as famous. It had its first season m 1824. Having gained fame with its productions of plays by Griboyedov, Gogol and Ostrovsky the theatre continues to play an outstanding part in Russian's cultural life. Drama theatres and studios are also very popular
