SKIN, ITS FUNCTIONS AND STRUCTURE, PREVENTION OF SKIN DISEASES
The skin is a complex polyfunctional body, designed to perform, above all, a protective function - it serves as an obstacle to all sorts of harmful and traumatic factors. In addition, physiologically active substances produced by the skin prevent the penetration of pathogenic microbes through it. The skin is also involved in thermoregulation, the synthesis of certain vitamins and in many other vital processes. Important functions of the skin are the removal of toxic products formed in the process of metabolism and vital microflora. Thus, in particular, in violation of the antitoxic activity of the liver and the excretory function of the kidneys, the ability to remove toxic products from the skin increases many times. As a result, skin sensitization occurs, and sensitized skin becomes less resistant to any stimuli. Then there are various pathological processes, eczema, pustular diseases develop. Hypovitaminosis, hormonal imbalance, inadequate nutrition, blockage of the excretory ducts of the sebaceous and sweat glands also contribute to the latter. Therefore, systematic skin care (washing, combing and brushing) serves as a good prevention of many skin diseases.
The skin is formed by three layers. The surface layer is the epidermis, consisting of a stratified squamous squamous epithelium. The epidermis is thicker and more resilient in the area of the nose and footpads, and thin, susceptible to damage in the area of the inguinal fold and axillary zones. Under the epidermis is the skin itself - the dermis. Its surface layer adjacent to the epidermis is called papillary, and the deeper layer is called reticular. In the reticular layer are lymph vessels and hair follicles with sebaceous glands. The sebaceous glands produce sebum, which lubricates the hair and gives it water repellency. Three types of hair are formed in the hair follicles: primary (guard) hair, secondary hair (undercoat), and vibrissae (mustache, cans, eyebrows, and hair on the back of the front paws). There are no sweat glands in the skin of cats, with the exception of special glands between the fingers on the paw pads, which secrete a secret in the heat, as well as when the cat is frightened or in a state of extreme excitement (while on the dry surface the cat leaves wet marks).
More than half of all cases of animal skin diseases occur in chronic pruritic dermatosis: eczema, neurodermatitis, atopic dermatitis, and others. In most cases, skin diseases are caused by several reasons, but most of these diseases reflect a violation of the activity of internal organs. The most common cause of skin diseases are digestive disorders. The main subjective symptom - pronounced pruritis, accompanied by combing. There are excoriations covered with bloody crusts. Excitations cause new bouts of itching and at the same time constitute a favorable entrance gate for a bacterial infection and the development of an inflammatory reaction. To achieve a good effect, it is necessary to pay attention not only to comorbidities, but also to take into account the factors of hormonal imbalance, stress, reduced immunity, fatigue.
Omega-3 and omega-6 fatty acids, which are contained, for example, in flaxseed oil, in fish oil, in fatty sea fish (mackerel, sardines, herring, salmon), are a good way to fight inflammation. They are also found in the best dry food. Thus, in all dry feeds Science Рlan Feline Sensitive Skin Formula Adult a unique combination of high-quality egg protein and amino acids methionine, lysine and tryptophan is combined with high levels of omega-3 and omega-6 fatty acids.
In addition, to eliminate the allergic component observed in many skin diseases, it is recommended to use bactoneotim to normalize the intestinal microflora.
For quality treatment, it is necessary to pay attention not only to comorbidities, but also to take into account the factors of hormonal imbalance, stress, reduced immunity. In the treatment of diseases of this group are widely used desensitizing, immunocorrective agents, treatment with UV rays, as well as drugs of hormonal nature. However, even the topical use of corticosteroid drugs with long-term therapy is often a significant risk for a sick animal. A quick transition to effective non-steroid drugs for external use without systemic risk that would stabilize the success of treatment and reduce the possibility of relapse is required.

SKIN, ITS FUNCTIONS AND STRUCTURE, PREVENTION OF SKIN DISEASES
- PREVENTION AND TREATMENT OF THE SKIN DISEASES
When you enter a large department store, it seems to you that most of the lower shelves are given to the objects of maintaining female beauty. Every year huge sums of money are spent by people to buy skin care products. But the skin of the horse, we do not always pay due attention. On a summer day, when we look at a healthy horse, whose skin is glittering in the sun,
- General symptomatology of skin diseases
The clinical picture of skin diseases is a complex symptom complex. All symptoms of the disease are divided into subjective and objective. The subjective ones include manifestations of the disease that the patient himself feels (itching, burning sensation, tingling of the skin, soreness), to objective ones - changes that the doctor finds on the skin or visible mucous membranes during examination or during their palpation. Often
- The structure and function of the skin
The skin is an element of the body's immune system, the protective covering of a person, which has an effect on the functioning of all internal organs and systems. The skin performs a number of vital functions that ensure the normal functioning of all body systems. The main functions of the skin include: protective function thermostatic function, exchange function, receptor function, participation in
- STRUCTURE AND FUNCTION
If now I return to the secretin and describe it as a protein molecule, then we will immediately learn something about its structure. Moreover, it is a small protein molecule. a molecular weight of only 5,000. (This means that a secretin molecule weighs 5,000 times more than the lightest atom is a hydrogen atom.) If we start to discuss molecules of other compounds, the weight of 5,000 may seem sufficient
- The structure and function of the brain
The brain, both in structure and in its functions, is an exceptionally complex organ. It is the main center in which the relationship of the organism with the external environment. Signals from the external environment enter the brain through the system of external receptors. The external world of sound, light, olfactory, tactile, vibration-kinesthetic stimuli affects our brain and
- Structure and function of the kidneys
On the incision of the kidney, it is clearly seen that immediately below the thin connective tissue capsule there is a moderately dense Scheme 18.1. The structure of the nephron is a cortex (0.7–0.8 cm thick), and below it is a medulla represented by pyramids. The parenchyma of the cortical and medulla in one kidney is 1 - 1.5 million structural-functional units of the organ - nephrons. Each nephron has
- The structure and function of the spinal cord
The spinal cord is located in the spinal canal formed by the lateral processes of the vertebrae. Being a continuation of the brain stem, the spinal cord has its own specific structure. It has the appearance of a white cord about 1.5 cm thick. In the cervical and lumbar regions there are thickenings associated with the innervation of the upper and lower extremities. The length of the spinal cord depends on the height of the person and
- The structure and function of the protein
Proteins play a crucial role in the life of any organism. The diversity and complexity of living matter, in fact, reflect the diversity and complexity of the proteins themselves. Each protein has its own unique function, which is determined by its inherent structure and chemical properties. Some proteins are enzymes, i.e. catalysts of biochemical reactions in living organisms. Each
- Neuroglia, structure, types, functions
Neuroglia, or simply glia, is a complex complex of auxiliary cells of the nervous tissue, common in functions and, in part, in origin (the exception is microglia). Glial cells make up a specific microenvironment for neurons, providing conditions for generation and transmission of nerve impulses, as well as carrying out part of the metabolic processes of the neuron itself. Neuroglia performs support,
- Structure and function of the nervous system
By its structure, the nervous system consists of two parts: the central nervous system and the peripheral. The central nervous system is the brain, located in the cranial cavity, and the spinal cord, enclosed in the spinal canal. The substance of the brain when viewed with the naked eye is colored differently. There is gray matter consisting of the bodies of nerve cells, and white
- BUILDING ANIMAL CELL. BASIC ORGANIZATIONS AND THEIR FUNCTIONS
All living organisms, depending on the type of their constituent cells, are divided into eukaryotes (cells with a nucleus) and prokaryotes (cells that do not have a decorated nucleus). Eukaryotic cells consist of a wide variety of organisms; higher plants, fungi, unicellular amoebas and multicellular animals. Individual cells from different parts of a higher organism can substantially
- The structure and function of the cerebellum
The cerebellum is the focal point of movement. It is located in the posterior cranial fossa together with the brain stem. The roof of the posterior cranial fossa is the basement of the cerebellum. The cerebellum has three pairs of legs. These legs are formed by cerebellar pathways (afferent and efferent). The upper cerebellar legs are located at the level of the midbrain, the middle - at the level of the bridge, the lower - at the level
- Neuron. Its structure and functions
A neuron is a structural-functional unit of the nervous system that performs the perception, processing and transmission of information in the nervous system, as well as the connection between the periphery and the brain by the executive organs. Neurons transmit pulses in one direction. In the center of the body there is a nucleus from the body of the neuron there are several short processes that are called dendrites - usually short and strongly
- The structure and function of the respiratory tract
The respiratory tract includes: the nasal passages, the oral cavity, the larynx, the trachea, which is divided into 2 main bronchi, each of which in turn is also consistently and repeatedly dichotomously divided. From the teeth to the tracheal bifurcation, the length of the respiratory tract is 22 - 24 cm. The diameter of the glottis in the diameter is 7 mm, the longitudinal - 17-20 mm. The vocal cords open when inhaling and close
- Basic information about the structure and function of the heart is normal
Chapter 1 (see Table 1.1) outlined the most important linear and weight parameters of an adult's heart. Recall some of the structural and functional characteristics of the valves of the heart and myocardium, and then focus on the features of the blood supply and aging of this organ. Valves of the heart. The main functional purpose of the valves of the heart and large vessels is to prevent the reverse flow of blood.
- The unity of discontinuity and continuity in the structure and function of the heart
Fibrillar contractions of the heart muscle is not the only phenomenon that contradicts the generally accepted view of this muscle as a continuous syncytia. Numerous data indicate that the myocardium, both in structure and function, is as discontinuous as in continuous education. The same applies to the cardiac conduction system. Morphological studies show
