III. Independent Work: How to Go on a Diet?

Exercise 1. Read an unfinished story and continue it (you can use the ideas given below).

How to Go on a Diet?

Last summer my doctor told me to go on a slimming diet, which, he said, would make me lose twenty pounds in a month. For breakfast, I was allowed to drink coffee or tea and nothing else. For lunch, grilled meat, no salt; a hundred grams of vegetables, no salt; fifty grams of cheese or yoghurt, a choice of an orange or an apple. The same for dinner. I wasn't allowed to drink anything with meals.

The first day was fine, though I was so hungry that I went to bed at eight. The next morning my wife said an egg with breakfast wouldn't hurt me. So I ate an egg since she is wiser than I am in these matters.

At noon I lunched with a friend who said, "Meat is more fattening than potatoes. My doctor lets me eat all the potatoes 1 want to, without butter, of course". So I had potatoes with my meat. In the evening і dined with a Frenchman. He was shocked to think that I wouldn't drink wine with my dinner. So I had half a bottle of Burgundy with my dinner. I went on dieting taking my meals with different people. Each one had his own idea about dieting and I was willing to listen to everybody.

Ideas

Describe my meals with my lawyer, an American visitor, my colleague, my mother-in-law, my hairdresser. This is what they say: one teaspoon of cream is three times as fattening as one teaspoon of sugar; it is foolish to eat without salt; the best way to lose weight is to eat nothing but spaghetti; fish is not fattening; scrambled eggs in the morning aren't as fattening as in the evening; if you eat a lot of chocolate before dinner it will take away your appetite.

Exercise 2. Answer the questions.

!. Do you think 1 liked to take my meals alone or with friends? 2. Do you think 1 have put on or lost weight? 3. What do you think my doctor said? 4. Why is it not wise to listen to everybody?

Nervous System

(Part I)

 

None of the body systems is functioning alone. The body systems work together as one unit and the nervous system serves as a chief coordinating center. The nervous system has been compared to a telephone exchange, in that the brain and the spinal cord act as switching centers, and the nerve trunks act as cables for carrying messages to and from these centers.

The nervous system structurally is divided into the central nervous system (CNS), which includes the brain, the spinal cord, and the peripheral nervous system (PNS), which includes all of the cranial and spinal nerves (Fig. 19-1).

Functional divisions of the nervous system include the somatic (voluntary) nervous system, which supplies skeletal muscles, and the visceral (involuntary) nervous system, which supplies smooth muscles, cardiac muscles, glands.

The nerve cell is called a neuron (Fig. 19-2). It consists of a cell body with a nucleus and nerve fibers, which are thread-like projections of the cytoplasm. Nerve fibers are of two kinds: dendrites, which conduct impulses to the cell body, and axons, which conduct impulses away from the cell body.

The job of neurons of the peripheral nervous system is to relay information to or from the central nervous system. Neurons that conduct impulses to the CNS are sensory, or afferent, neurons. Those cells that carry impulses from the CNS out to muscles and glands are motor, or efferent, neurons. The organ activated by the motor neuron is the effector.

Nerve impulse is electric current that spreads along the nerve fiber.

Synapse is the junction between neurons where a nerve impulse is transmitted from one neuron to the next.

A nerve is a bundle of nerve fibers located outside the CNS. Bundles of nerve fibers within the CNS are tracts.

The nerves are sensory (afferent), they contain only fibers that carry impulses toward the CNS (from the receptor); motor (efferent), they contain only fibers that carry impulses away from the CNS (from the receptor); mixed, they contain both motor and sensory fibers.

Reflex is a simple, rapid, automatic response involving few neurons.

III. Independent Work: Role of Nervous System

Exercise 1. Read and translate the text.

Role of Nervous System

The nervous system regulates the activities of different organs and of the entire organism. Muscular contractions, glandular secretion, heat action, metabolism and many other processes continuously operating in the organism are controlled by the nervous system.

The nervous system links the various organs and systems, coordinates all their activities and ensures the integrity of the organism.

The work of each organ or system of organs may be affected by various conditions. A change in function of one organ or system of organs leads to changes in the function of other organs and systems. For example, during physical work involving intensive muscular contraction the metabolism in muscles increases, which consequently increases the requirement in nutrients and oxygen. A reflex response causes the heart and lungs to work more intensively, with the result that the flow of the blood to the muscles increases. At the same time heat production and heat loss increase, the excretory organs work harder.

The unity of the organism and its external environment is affected through the nervous system. All the outside stimuli are perceived by the nervous system through the sense organs. In response to the stimuli the functions of the various organs change and the organism adapts itself to its surroundings or, as I. Pavlov put it1, the organism is equilibrated with the external environment. This equilibrium forms the basis of the organism's vital activities. Thus in response to ingestion of food the activity of the digestive glands increases and is adapted to the character of the ingested food. A rise in temperature of the surrounding air causes an increased flow of blood to the skin and greater perspiration, which prevents overheating of the organism.

It should be remembered that unlike animals, man can himself considerably change his external environment.

Man's brain is the material basis of thinking and speech.

I. Pavlov demonstrated that man's so-called psychic activity is based on physiological processes operating in the cerebral cortex.

Note:

1 as I. Pavlov put it - як сформулював І. Павлов

Exercise 2. Make up a plan of the text.

Exercise 3. Find sentences about the nervous system.

- the branches of the spinal nerves;

- the disorders of the spinal nerves;

- the parts of the autonomic nervous system;

- the functions of the autonomic nervous system.

 

Text 1. Spinal Cord

The spinal cord occupies the spinal canal, but not all of it in the lower part. In adult the cord ends in the region just below the area to which the last rib attaches (between the first and the second lumbar vertebrae).

The spinal cord consists of gray matter (nerve cell bodies) and a larger area surrounding this gray part that consists of white matter (nerve fibers). The structure of the spinal cord is shown in Fig. 20-1.

You can see that the gray matter has the form of the letter H or a butterfly (метелика). The functions of the spinal cord may be divided into three categories:

- reflex activities;

- conduction of sensory impulses (to the brain);

- conduction of motor impulses (from the brain).

All the nervous activities are taking place through the reflex arcs. The reflex arc consists of five components: the receptor, the afferent pathway, the nervous center, the efferent pathway and the effector.

The diseases of the spinal cord are: poliomyelitis (an infectious disease, which commonly occurs in children; polio virus enters the body through the nose and throat; the virus destroys



the motor nerve cells in the spinal cord; the preventive medicine is the oral Sabin vaccine), paraplegia (the loss of sensation and motion in the lower part of the body), tumors that grow from within the cord or that compress the cord from outside.

 

Text 2. Spinal Nerves

 

Look at Fig. 19-1. There are

31 pairs of spinal nerves, each pair is numbered according to the level of the spinal cord from which it arises. Each spinal nerve has small posterior divisions and rather large anterior divisions.

The larger anterior branches

form networks called plexuses, which innervate (іннервують) different parts of the body.


The three main plexuses are described as follows:

1. The cervical plexus supplies motor impulses to the muscles of the neck and receives sensory impulses from the neck and the back of the head. The phrenic nerve, which activates the diaphragm, arises from this plexus.

2. The brachial ['braskial] plexus sends numerous branches to the shoulder, arm, forearm, wrist and hand. The radial nerve emerges from the brachial plexus.

3. The lumbosacral [^Amba'seikral] plexus supplies nerves to the lower extremities. The largest of these branches is the sciatic [sai'aetik] nerve, which leaves the dorsal part of the pelvis, passes the glutaeus maximus muscle and then to the thigh, and lower leg, and foot.

The disorders of the spinal nerves are:

- neuritis (inflammation of a nerve);

- sciatica [sai'astkka] (kind of neuritis characterized by severe pain along the sciatic nerve);

- herpes zoster (known as shingles) is characterized by numerous blisters along the course of certain nerves (the cause is the chickenpox virus).

 

Text 3. Autonomic Nervous System

Look at Fig. 20-2. The autonomic nervous system is the motor (efferent) division of the visceral (involuntary) nervous system. It has many ganglia that serve as relay stations. In these ganglia each message is transferred at a synapse from the first neuron to the second one from there to the muscle or gland cell. This differs from the voluntary (somatic) nervous system, in which each motor nerve fiber extends all the way from the spinal cord to the skeletal muscle with no intervening synapse.

The autonomic nervous system has sympathetic pathways and parasympathetic pathways.

The sympathetic pathways begin in the spinal cord with cell bodies in the thoracolumbar area and then their nerve fibers extend to ganglia where they form a synapse with a second set of neurons, whose fibers extend to the glands and involuntary muscle tissues. These second neurons act on the effectors by releasing the neurotransmitter epinephrine (adrenaline), so the sympathetic system can also be called adrenergic [aedri пз:дзік].

The parasympathetic pathways begin in the craniosacral areas, with fibers arising from cell bodies of midbrain, medulla, and sacral part of the spinal cord, and stimulate the visceral tissues. The neurons of this part of the nervous system release the neurotransmitter acetylcholine, so it is called cholinergic [кт)1і'пз:дзік].
