Exercise 5. Read and translate the text:

Living tissue is made up of cells There are manv different tvoes of celld, but all have tne same basic structure. Tissues are layers of similar cells that perform a specific function. The various kinds of tissues group together form organs.

There are four basic types of tissues:

• Connective tissue supports otner tissues\and binds them together. This includes bone, blood, and lympiTtissues in addition to the tissues that give support and structure to the skin and internal organs.

• Epithelial tissue provides a covering for deeper body layers. The skin and the linings of the various passages inside the body are made of epithelial tissue.

• Muscle tissue includes three types of tissue,

• Striated muscles, such as those that rmove the skeleton (also called voluntary muscle)

• Smooth muscles (also called involuntary muscle), such as the muscles that surround the stomach and other internal organs

• Cardiac muscle, which makes up most of the heart wall (also involuntary muscle)

• Nerve tissue is made up of nerve cells (neurons) and is used to carry messages to and from various parts of the body. The brain is made of nerve tissue.

The study of tissue is known as histology or, in connection with disease, histopathology.

The classical tools for studying tissues are the paraffin block in which tissue is embedded and then sectioned, the histological stain, and the optical microscope. In the last couple of decades, developments in electron microscopy, immunofluorescence, and the use of frozen tissue sections have enhanced the detail that can be observed in tissues. With these tools, the classical appearances of tissues can be examinedfinliealth and disease enabling considerable refinement of clinical diagnosis and prognosis.

Exercise 6. Answer the following questions:

1. How many basic types of tissues are there?

2. What are the functions of connective tissue?

3. What does epithelial tissue provide?

4. How many types of tissue does muscle tissue include?

5. What muscles are also called voluntary muscle?

6. What muscles are also called involuntary muscle?

7. What muscle is made up of nerve cells?

8. What study leams about tissues?

9. What are the classical tools for studying tissues?

10. What developments have enhanced the detail that can be obseived in tissues?

Exercise 7. Give English equivalents of the following word combinations:

Живі тканини; сполучна тканина; виконувати функції; м'язи, що мимов.олі скорочуються; глибокі шари; нести повідомлення; серцевий м'яз; класичні інструменти; парафіновий блок; пара десятиліть; спостерігати в тканинах; що дає можливість значно поліпшити.

Exercise 8. Read and translate:

Histology is the study of the microscopic anatomy of cells and tissues of plants and animals. It is performed by examining a thin slice of tissue under a light microscope or electron microscope. The ability to visualize or differentially identify microscopic structures is frequently enhanced through the use of histological stains. Histology is an essential tool of biology and medicine.

Histopathology, the microscopic study of diseased tissue, is an important tool in anatomical pathology, since accurate diagnosis of cancer and other diseases usually requires histopathological examination of samples. Trained medical doctors, frequently board-certified as Pathologists, are the personnel who perform histopathological examination and provide diagnostic information based on their observations.

Exercise 10. Translate into English:

1. Існує чотири основні види тканини: сполучна тканина, епітеліальна тканина, м'язова тканина і нервова тканина.

2. Сполучна тканина підтримує інші тканини і зв'язує їх разом.

3. Епітеліальна тканина забезпечує покриття різних проходжень усередині тіла.

4. М'язова тканина включає смугасті м'язи,що допомогають скелету рухатися, і гладкі м'язи, наприклад м'язи, які оточують шлунок.

5. Нервова тканина складається з нервових клітин і нести інформацію в різні частини тіла.
