Ontogeny is the development of an individual being and differs from phylogeny, which is known as phylogenetic development. The concept of ontogenesis goes back to Ernst Haeckel. In modern psychology and medicine

During mineralization, mineral substances are stored in hard tissue, such as teeth or bones, for hardening. There is a permanent balance between mineralization and demineralization in the body. If there is a mineral deficiency or otherwise

Amino acids are one of the most important substances for the human body. Without this, the metabolism cannot produce proteins, liver metabolism, growth, structure of the skin, nails and hair and the functioning of the nervous system would not be possible.

The liver is the largest gland in the human organism. It is also a vital organ, since the liver metabolism is at the center of the entire metabolism.

Gluconeogenesis ensures the new synthesis of glucose from pyruvate, lactate and glycerine in the body. This ensures the organism's glucose supply in times of hunger. Disturbances in gluconeogenesis can lead to dangerous hypoglycaemia f

The term catabolism encompasses all metabolic processes in the body, in the course of which the complex and sometimes high-molecular proteins, carbohydrates (polysaccharides) and fats are broken down into their simpler building blocks - mostly with energy production

Fat breakdown, also called lipolysis, takes place mainly in the fat cells (adipocytes). The most important function of lipolysis is to generate energy. But there are also disturbing influences that inhibit fat loss.

The process of making hormones is called hormone synthesis. Hormones are biochemical messenger substances that are released by hormone-producing cells and cause certain effects on target cells.

The female cycle or menstrual cycle is understood to mean the woman's monthly menstrual period. Its length averages 28 days.

The oral phase is a developmental stage in the child's first year of life when they explore their environment with their mouth. During the oral phase, the baby tries to put all kinds of objects in his mouth.

In Sigmund Freud's psychoanalysis, the anal phase describes a section of early childhood development. The anal phase follows the oral phase and begins at the age of two. The excretory functions of the

Vasculogenesis is a process of embryonic development in which the vascular system is created from endothelial progenitor cells. Vasculogenesis is followed by angiogenesis, which causes the first blood vessels to sprout. In the broadest sense

The pulmonary circulation, also known as the small bloodstream, is part of the human cardiovascular system. It regulates the transport of blood between the heart and the lungs and is used for gas exchange, i.e. the absorption of oxygen into the blood and the

In biology, proliferation means the reproduction and growth of cells. The cells multiply through cell division and grow through growth to their genetically intended size and shape. The proliferation plays

The human body is regenerative and recovers through rest, nutrition and targeted exercise. Most of the human cells renew themselves at regular intervals. This process of regeneration is genetically determined, but is also used by

Heart rhythm is the complete repetitive sequence of heartbeats including electrical excitation and heart muscle contractions. In people with a healthy cardiovascular system, the atria first contract and pump

In clinical usage, systole is used to describe the tension and subsequent contraction phase of the two heart chambers. During the contraction phase, the two leaflet valves are through which the blood from the two antechambers into the chambers

Flexion is one of the main movements in the human motor system. It occurs on the spine and many limb joints.

Squatting as a posture has gone a little out of fashion in industrialized countries. The squat can have positive effects on the musculoskeletal system in everyday life and in sports.

There are 3 different causes of muscle breakdown. On the one hand, the "normal" loss in the context of the aging process comes into question. On the other hand, the decrease in muscle mass can be the result of inactivity or a disease of the muscles or the nervous system
