The study of the morphology of microbes also serves to differentiate them. Morphology is studied in stained preparations. They determine the shape and size of cells, their location in the preparation, the presence of spores, capsules, flagella. In stained preparations, the ratio of microbes to paints (tinctorial properties) is determined — paints are well or poorly perceived as they relate to differential stains (what color is stained according to Gram, Tsil-Nielsen, etc.).

- Physical properties of water (temperature, transparency, color, taste, smell) and the effect of these properties on human health.
These include smell, taste, color and transparency, that is, those properties that can be determined by the human senses. Turbid, dyed in any color or having an unpleasant smell and taste, the water is not sanitary-hygienic inadequate even if it is harmless to the human body. Deterioration of the properties of water adversely affects the drinking water regime, reflexively
- 21. INSPECTION AND PALPATION OF PERIPHERAL VESSELS. RESEARCH OF THE ARTERIAL PULSE. PULSE PROPERTIES (7 BASIC PROPERTIES).
Inspection of arteries: In young people, at rest, a pulsation can be observed: 1. Carotid artery on the neck. 2. Truncus brachiocephalicus in the jugular fossa. 3. Connect the arter in the subhole. 4. Abdominal aorta. In older people, an additional definition of pulsating arteries: 5. Shoulder 6. Elbow 7. Superficial temporal temporal pulsation; art can be detected in healthy people, which means physical and / or emotional stress. when ^

The gray noises are the sounds that are called. Instead of heart sounds (C), accompanied by tones C or occur without any connection with tones C. Classification: I. inside the sulfuric: a-organ-it is 1 valve, 2 non-valve; b-functions are 1-intermediate, 2-pure functions, 3-physical ones; II extra-e: a-perekardia-e, b-pleuropericardi-e, c-cardiopulmonary Mech m of internal noise Noises C - these are mechanical oscillations of the engine caused by
- 22. RESEARCH OF PERIPHERAL VESSELS. PROPERTIES OF THE ARTERIAL PULSE IN PATHOLOGY (CHANGE OF RHYTHM, FREQUENCY, FILLING, VOLTAGE, WAVE FORM, PROPERTIES OF THE VASCULAR WALL OF THE VESSEL).
On palpation of the common carotid, humeral, ulnar, temporal, femoral, popliteal, and rear art stops, the tasks are narrowed down to an approximate assessment of the pulsatory movements by voltage and filling. The carotid artery is palpated on the left and right in a delicate way, removing the sternoclavicular-nipple muscle outwards at the level of the thyroid cartilage, palpating the facts of the common carotid artery on the left and right.
- Morphological classification
There are hydrocephalus open (communicating), closed (occlusal) and ex vacuo. Open hydrocephalus involves the free communication of liquor-bearing spaces: its development is associated with a violation of the ratio of production processes and resorption of cerebrospinal fluid. Hyperproduction, aresorbent and mixed forms are distinguished, in which production processes prevail over resorption processes.
- Clinical and morphological characteristics of skin rash elements
Diagnosis of skin diseases, in addition to complaints, an anamnesis of life and illness, is based mainly on the morphological elements of skin rashes. Therefore, their knowledge is basic in the practice of a dermatovenerologist. > Morphological elements are divided into primary, arising on unchanged skin, and secondary, formed during the evolution of primary elements. Primary morphological elements
- Secondary morphological elements
They arise in the process of evolution of primary morphological elements. These include: 1) pigmentation - or dyschromia of the skin. It occurs at the site of vesicles, pustules, erosion, ulcers after their healing; 2) flake (squama) - loosened rejected cells of the stratum corneum, having lost contact with the underlying epidermis. With pityriasis versicolor observed pityriasis peeling, dermatitis
- Morphological structure and chemical composition of chromosomes
Microscopic analysis of chromosomes primarily shows their differences in shape and size. The structure of each chromosome is purely individual. You can also notice that chromosomes have common morphological characteristics. They consist of two strands — chromatids, arranged in parallel and interconnected at one point, called the centromere or primary constriction. On some chromosomes
- Morphological elements
Dermatology (Greek skin teaching) is an area of clinical medicine that studies the structure and functions of the skin in normal and pathological conditions. Dermatology develops issues of etiology, pathogenesis, diagnosis. Therapy and prevention of dermatoses, as well as the relationship of skin diseases with other pathological conditions of the body. Dermatology is divided into general and private. General dermatology covers
- MORPHOLOGICAL AND CHEMICAL COMPOSITION OF MEAT
Depending on the type of wild animals, their meat differs in organoleptic characteristics, morphological and chemical composition, taste and culinary qualities. In meat of young animals, unlike meat of adults, less fat and more loose connective tissue. Fat in wild animals is deposited under the skin, in the pelvic cavity, in the lumbar, near the kidneys and only with high fatness in
- Particular morphological characteristics of helminth eggs and larvae
Particular morphological characteristics of eggs and larvae of helminths inherent in owners of certain species are given in the captions under the illustrations. MICROMETRY OF EGGS AND HELMINT LARVAS Micrometry is necessary for the differential and more accurate diagnosis of individual pathogens whose eggs and larvae have morphological similarities. For microscopic measurements, a special eyepiece micrometer, in
