Text A. The Brain

Scientists consider that our brain is the most complicated mechanism which has ever been constructed.

The weight of the human brain is from 1 to 2 kg (kilograms). It has a volume of about 3.21 l (litres) and consists of about 12 billion (миллиард) cells. It has been determined by the scientists that each cell is connected to the other directly or indirectly by nerve fibers.

The brain is the centre of a wide system of communication. It has been found out that a constant flow of stimuli comes into the brain through the spinal cord. The stimuli come to the brain from our eyes, ears, and other sense organs for pain, temperature, smell and other feelings. When all the received stimuli have been summarized and analysed the brain sends orders through the nerve fibers in the spinal cord to different parts of the human body. It is due to these orders that one eats, moves, hears, sees and does many other things.

To estimate the functions of different areas of the brain many experiments have been carried out by the investigators. It is due to such experiments that the investigators have been able to determine those areas of the brain which control vision, hearing, physical movements and even emotions.

Due to experimental studies it has been determined that the motor cortex controlling many body movements of the human being becomes tired rapidly. But the hypothalamus which controls such functions as blood pressure is almost never tired.

CLASS ASSIGNMENTS

XII. Say the following sentences in the Past and Future Perfect Passive:

The work has been completed. 2. The important findings have been proved. 3. The number of leucocytes has been counted. 4. A female patient has been transferred to the hospital.

XIII. Make the following sentences negative and interrogative:

The motor cortex controls many movements of the human being.

During the systole both ventricles of the heart contract. 3. On deep respi

Ration the vital capacity of the lungs may become 6 litres. 4. In 1538 Andreas Vesalius published his six-volume work “Tabulae Anatomicae”.

XV. Translate these word combinations:

Constant communications between sense organs; 2) a complicated case; 3) in the heart area; 4) the feeling of pain; 5) to control a disease; 6) to examine hearing; 7) to analyse the dysfunction of movements.

XVI. Choose the nouns that can be used with the given verbs:

XVIII. Read the passage and say what interesting things you have learned:

If the human being has a bad headache he often feels pain within the skull. But really the nerves through which pain stimuli pass exist mainly in the blood vessels and nervous system, but not in the proper substance of the brain. So, the brain itself does not feel pain.
