The ultralong feedback mechanism is a feedback process in the human body that is particularly important for the hormonal balance. Such a self-regulating feedback is, for example, the interplay between the thyroid

The Fåhraeus-Lindqvist effect is a blood flow phenomenon that is based on the fluidity of the erythrocytes and is related to the viscosity of the blood. The viscosity in vessels of the circulatory periphery with a narrow lumen is lower than

The marginal flow of blood is the flow of blood in close proximity to the walls of the vessels. Especially in the smaller vessels, there is a plasmatic marginal current without leukocytes and erythrocytes, which has a significantly lower flow rate

The Gordon finger spreading sign is a reflex that can only be triggered under pathological conditions. It is considered an uncertain pyramidal orbit sign and can also provide evidence of vegetative overexcitability.

The Wartenberg reflex is a reflex from the group of pathological reflexes. It belongs to the pyramid orbit signs and thus provides indications of a disease of the nervous system.

The Trömner reflex is a muscle reflex (increased finger flexion reflex) that can occur in almost every healthy person. It is considered a sign of vegetative overexcitability and, in strong or one-sided expression, also as a pyramidal orbit sign

The walking reflex is one of many early childhood movement reflexes that are triggered by certain stimuli. When the baby is held up under the armpits and the feet feel a firm surface, it moves the legs in a kicking manner

The Westphal-Piltz phenomenon is an eyelid-closing reaction in which the pupils of the eyes shrink. It occurs together with Bell's phenomenon and is used for the differential diagnosis of disorders of the pupillary motor skills.

The sneezing reflex is one of the protective reflexes and corresponds to a "false" external reflex. Sneezing clears the upper airways of nasal secretions and foreign matter to ensure free breathing. Disturbances of the sneezing reflex occur mainly

The gene expression describes the expression and development of a genetically predisposed characteristic of a living being. On the other hand, there is genetic information that is not expressed and that can only be detected using a DNA analysis.

Priming is an effect of neuroanatomy and is also known as facilitating. A stimulus that was received earlier is processed more effectively by the nervous system when it occurs repeatedly. Degenerative brain diseases make priming difficult

Vascular constriction, also known as vasoconstriction, is the result of contractions of the tunica media. These contractions are either triggered by an increase in sympathetic tone or they are hormonally controlled. Pathological vascular obstruction

The amount of fluids that we drink every day has to be excreted through the urinary tract. The discharge from the body takes place by emptying the bladder - micturition.

We mainly associate creativity with artistic creation, with creative activities such as painting, dancing, singing, drawing, making music, etc. However, creativity is much more than that.

In the broadest sense, motility corresponds to active mobility. In medicine, the term primarily refers to the involuntary movements of the peristalsis or is used for the ability of muscles to contract, which in turn

With propulsive peristalsis, the smooth muscles transport food from the esophagus to the rectum. The wave-shaped and locally synchronized contractions are subject to modulation by the sympathetic and parasympathetic nervous systems

Selective perception is based on the natural mechanism by which the human brain searches for patterns in its environment. Due to the selective character, people are more likely to perceive what can be inserted into a pattern. Clinical relevance

Peristalsis represents the muscle movement of various hollow organs. Non-propulsive peristalsis mainly occurs in the intestine. It serves to mix the intestinal contents.

Retrograde peristalsis is a muscle movement of hollow organs such as the esophagus, stomach, intestines, ureters, uterus and fallopian tubes. During this movement, they actively transport their content against the physiological direction. The

In addition to tasting, seeing, feeling, hearing and smelling, people can orientate themselves with the help of their deep sensitivity. This ability enables him to assume a certain position and make movements. If it is disturbed, it comes to an accident
