Problem 1. During treatment by hormone medicine named cortizol in the cells of men the acceleration of metabolism take place. What structural changes in the cytoplasm of cell are there?

1. Quantity of ribosomes becomes more.

2. Quantity of ribosomes becomes less.

3. Quantity of polysomes becomes more.

4. Quantity of polysomes becomes less.

5. Quantity of lysosomes becomes less.

Problem 2. During microscoping was found that quantity of ribosomes and polysomes becomes more. What does take place: activation or repression of protein synthesis? What are the other changes in cytoplasm structure?

5. Summarizing of the STUDY by the teacher and validation of performance of work by everyone student.

1. Medical Biology: Textbook. - Simferopol: IAD CSMU, 2002. – P. 29 – 44.

STUDY 21

Theme: BIOLOGY of a CELL. A CELL AS ELEMENTARY GENETIC MORPHOlogical and FUNCTIONAL BIOLOGICAL UNIT. nucleus.

1. The MEANING of the THEME. The study of a microscopical constitution of cell nucleus allows more deeply to understand the causes of originating of pathologic process, promotes introduction in practice of new methods of diagnostics and treatment.

2. PURPOSE of STUDY. General: To receive representation about a cell nucleus to understand specifics organization of cells.

3. THE CONCRETE PURPOSES of STUDY:

3.1. To be able to find and to determine the basic components of a nucleus on microslides.

3.2. To receive representation about a nucleus ultrastructure.
