Presentation on the topic of tissue of living organisms. Plant and animal tissues. Generalization. The integumentary tissue of plants includes

The modern concept of modernization of a comprehensive school presupposes the orientation of education not only on the students’ mastery of a certain amount of knowledge, but also on
development of his personality, his cognitive and creative
abilities.
Modernization strategy
education:
competitiveness;
competence;
mobility;
ability to carry
responsibility.

The result for the individual is success, social competitiveness.

Socialization is the process and result of a child’s appropriation of social experience as his psychological, intellectual and

personal
development.
Social experience is always the result of the child’s actions, active
interactions with the outside world. Mastering the social world means
not just to assimilate the sum of information, knowledge, skills, samples, but to possess,
own the way of activity and communication, the result of which he
is.

A child's social experience is the result of his socialization and upbringing. Mastery of social experience occurs in three ways:

in interconnected ways.
Secondly, mastery
social experience
implemented as
goal-oriented
process: education,
education, training.
First of all, it's coming
spontaneously
Thirdly, social
child's experience
folds up and
spontaneously.

Working with primary school children, we, together with teachers, set ourselves the following tasks in the socialization of the child’s personality:

Adapt
Help

important, but
complex
vital
phenomena and give
children about them
representation
Fence
children from
asocial influences,
build skills
survival and spiritual
confrontation.
Help
Smooth
manifestations of social and
material stratification in children's
environment, to educate children about the basics
humanistic personal position in
conditions of property inequality;
to kid
contact your
life experience on
reflective level
make it an object
self-knowledge,
self-analysis.

Working on the development of social activity will help the child:

acquire a clear understanding of the norms and
rules existing in society;
learn to feel and understand others
of people;
join the common humanity
values: goodness, beauty, health,
happiness;
see the value of everyone and everything living
and growing on the earth;
gain self-confidence;
learn to make decisions and achieve
results according to
the set goal.

First, the idea of
yourself, your place in school
team. Games contribute to this
trainings, group work, reading and
discussion of books, role-playing games,
drawing, working with pictograms.
Games: “I am a student”, “Find a pair”,
"Getting acquainted", "Greeting"
"Talking on the phone".
Drawing on the topics: “My family”, “Who
dear to me", "The Beautiful and the Ugly",
drawing yourself

Tissues of the human body Biology teacher of MKOU secondary school No. 1, Liski, Voronezh region Podvigina N. M.

Tissue is a collection of cells and intercellular substance that are similar in structure, origin and functions. Tissues of the human body Epithelial Muscular Connective Nervous

Epithelial tissues In epithelia there is almost no intercellular substance, and the cells are closely and firmly connected to each other. The epithelium is firmly attached to the underlying tissues by a basement membrane - a dense plate of protein fibers. There are integumentary epithelia (single-layer and multilayer), whose main function is barrier, and glandular epithelia, which perform a secretory function. Location of the epithelium

Single-layer epithelia Inner wall of the blood capillary Inner lining of the renal tubule Inner mucous membrane of the trachea

Stratified epithelia Outer layer of skin Inner mucous membrane of the esophagus

Glandular epithelium Glands are organs (or parts thereof) or individual cells, the main function of which is the formation and release (secretion) of certain substances. Exocrine glands (exocrine) remove substances to the external environment: to the surface of the body or into the lumen of hollow organs. Endocrine glands (endocrine) secrete substances (hormones) into the internal environment - into the blood. Diagram of the structure of the endocrine gland Diagram of the structure of the exocrine gland

Glandular epithelium The pancreas has both exocrine and endocrine parts, which is why it is called a mixed secretion gland.

Cuboidal epithelium

Ciliated epithelium

Columnar epithelium

Flat epithelium

Connective tissues Connective tissues are characterized by a strong development of intercellular substance. The mechanical properties of numerous varieties of connective tissues, the general function of which is to unite all other tissues and organs and create support for them, largely depend on its properties.

Dense fibrous tissue Dense fibrous connective tissue forms muscle tendons, ligaments, and the outer membranes of organs. The dense arrangement of protein fibers gives it greater strength.

Loose fibrous tissue Loose fibrous connective tissue is present in all organs, uniting their elements.

Adipose tissue Adipose tissue forms the layer under the skin and the layers between internal organs. Contains fat cells almost completely filled with a large drop of fat.

Blood and lymph Blood and lymph have a liquid intercellular substance (plasma). Therefore, they can move through blood vessels, transferring substances between different parts of the body.

BONE TISSUE The intercellular substance of bone tissue is hard due to the deposition of crystals of calcium salts. Cartilage tissue has high elasticity.

Tubular bone section

Cartilage tissue Cartilage tissue has high elasticity. Hyaline cartilage Elastic cartilage

Muscle tissue The main property of these tissues is contractility - the ability to tense and shorten. This property is provided by cellular contractile proteins. There are smooth, cardiac and skeletal muscle tissues. The last two are called striated because in them the contractile proteins are ordered so that under a microscope the muscle fibers appear striated. The work of contractile proteins

Striated muscle tissue Contractile proteins are collected in bundles and laid along one axis with alternating actin and myosin.

Striated muscle tissue Forms the basis of skeletal muscles, providing body movement, as well as breathing and a number of other functions. Contains long (up to 10 cm or more) muscle fibers formed by the fusion of individual cells. These fibers are isolated from each other and can contract separately. Therefore, the force of skeletal muscle contraction can be smoothly adjusted by changing the number of fibers included in the contraction.

Smooth muscle tissue Contractile proteins are located in different directions.

Smooth muscle tissue Smooth muscle tissue is located in many organs and facilitates the movement of food through the gastrointestinal tract, urination, constriction of the bronchi and blood vessels, and other functions. Smooth muscle cells have an elongated shape and are usually combined with each other into bundles.

Cardiac muscle tissue Forms the heart muscle - the “engine” of blood circulation. The cells of this tissue are united into branched, interconnected fibers. Thanks to this structure, the heart muscle contracts as a single unit, which is very important for the normal functioning of the heart.

Nervous tissue Nervous tissue forms the nervous system and provides nervous regulation of body functions. It contains two main types of cells: nerve cells (neurons) and satellite cells (neuroglia cells).

Nervous tissue Nerve cells (neurons) receive, process and transmit information. A neuron consists of a body and processes. Dendrites are processes that transmit information to the neuron body. An axon is a process that transmits information from the body of a neuron. Functional types of neurons: 1. Sensitive neurons receive information. 2. Interneurons make up about 99% of all nerve cells and provide information processing. 3. Motor neurons transmit signals to the executive organs.

Nervous tissue Companion cells (neuroglia cells) provide support, protection, and nutrition to neurons. They are also involved in the formation of nerve fibers.

Synapses The transfer of information from neuron to neuron or to another cell is carried out by chemicals (mediators) through special intercellular connections - synapses. Synaptic vesicles are filled with transmitters. Between the membranes of neighboring neurons there is a synaptic cleft. Sodium ions float in it. When a neuron is excited, synaptic vesicles separate from the tubules and move to the outer membrane of the neuron. Having reached it, they open, and their contents (transmitter) enter the synaptic cleft. The mediators “float” to the membrane of the neighboring cell and “open” sodium channels. Na + ions rush into the neighboring neuron, causing a change in its charge.
