Topic 3. INTRODUCTION TO THE COURSE OF HISTOLOGY

Histology is the science of the structure, development and vital activity of the tissues of living organisms. Consequently, histology studies one of the levels of organization of living matter - tissue.

There are the following levels of organization of living matter:

1) cellular;

2) fabric;

3) structural and functional units of the organ;

4) organ;

5) systemic;

6) organismic;

7) population and other levels.

Histology is considered as a discipline that includes four main sections:

1) cytology, which studies the structure of the cell;

2) embryology, which studies the formation of cells and tissues during fetal development;

3) general histology - studies the structure, functional, cellular elements of various tissues;

4) private (or macroscopic) histology, which studies the structures of certain organs and their systems.

Thus, there are several sections in histology that study certain levels of organization of living matter, starting from the cellular and ending with the organ and system that make up the body.

Histology refers to the morphological sciences. Unlike anatomy, which studies the structure of organs at the macroscopic level, histology studies the structure of organs and tissues at the microscopic and electron microscopic levels. At the same time, the approach to the study of various elements is made taking into account the function they perform. This method of studying the structures of living matter is called histophysiological, and histology is often referred to as histophysiology. When studying living matter at the cellular, tissue and organ levels, not only the shape, size and location of the structures of interest are considered, but the chemical composition of the substances that form these structures is determined by the methods of cyto- and histochemistry. The studied structures are also considered taking into account their development both in the prenatal period and during the initial ontogenesis. It is with this that the need to include embryology in histology is connected.

The main object of histology in the system of medical education is the body of a healthy person, and therefore this academic discipline is referred to as human histology.

The main task of histology as an academic subject is the presentation of knowledge about the microscopic and ultramicroscopic (electron-microscopic) structure of cells, tissues of organs and systems of a healthy person in close connection with their development and functions. This is necessary for further study of human physiology, pathological anatomy, pathological physiology and pharmacology. Knowledge of these disciplines shapes clinical thinking.

The task of histology as a science is to elucidate the patterns of structure of various tissues and organs in order to understand the physiological processes occurring in them and the possibility of controlling these processes.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Supercomputer in Poland 26.11.2003

Intel introduced Poland's fastest supercomputer installed at the Academic Computing Center in Gdansk (TASK).

The supercomputer is a high performance computing cluster of 128 Optimus NSERVER systems and a total of 256 Intel Itanium processors. The cluster has a throughput of 1,3 triplion floating point operations per second (1,3 teraflops). It is expected to enter the top ten of the official ranking of the world's fastest supercomputing resources Clusters TOP 500+.

The computing power of the new cluster will provide invaluable assistance to the scientific community in Poland and will help to conduct pioneering research in the fields of chemistry, biotechnology, molecular modeling and computational fluid dynamics.
