The steps of perception including the perceptual content are known as perception. Perception therefore includes unconscious processes such as the filtering and evaluation of stimuli and conscious processes such as the classification and interpretation of perception

What is histogenesis? What is it for? Which complaints or diseases can arise from misdirected histogenesis? These questions are to be answered in the following article.

How is cell development defined? What functions, what tasks does it have in embryogenesis? Which diseases can occur that impair cell development? All of this is discussed below.

Medicine knows a process of thermoregulation as shivering, which tries to compensate for heat losses through automatic muscle activity in the event of a sharp drop in temperature. Shivering cold is triggered by the hypothalamus via the tremors. To disturbances

Phosphorylation is a fundamental process of biochemistry that takes place not only in the human organism, but in all living things with a nucleus and bacteria. It is an essential part of the intracellular

The opening phase is the introductory phase of childbirth. It is characterized by the onset of the first contractions, which open the cervix and cause the amniotic sac to burst.

Exocrine secretion is the delivery of a secretion to the inner or outer surface. This type of secretion occurs, for example, in the sweat or salivary glands. Sjogren's syndrome is an example of a disease that destroys the exocrine glands

The vascular resistance is defined by the physical resistance of a capillary, vein or artery that is opposed to the flowing blood. Vascular diseases can affect the entire organism but also an individual organ such as this

Pulmonary vascular resistance (PVR) is the resistance to flow of blood vessels in the pulmonary circulation. It is also called pulmonary vascular resistance and is used to regulate blood flow.

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 cerebral vascular resistance is one of the most important variables in the autoregulation of cerebral blood flow. It is a flow resistance with which the brain vessels meet the blood flow of the systemic blood pressure. With severe brain damage

The finger flexor reflex is a reflex of the finger flexors that is triggered by a blow on the palmar side of the middle finger phalanx. Excessive reflex diffraction is considered an uncertain pyramidal orbit sign or a sign of vegetative

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.

Protective reflexes are autonomous muscle movements that are triggered by external factors to protect a specific part of the body. The muscles involved are mostly skeletal muscles that are normally used for conscious, voluntary movement

The masseter reflex is a self-reflex of the masticatory muscles, which is triggered by a blow on the lower jaw and closes the jaw. The reflex is one of the muscle stretching reflexes and corresponds to an innate reflex movement of the masseter muscle

Villi movements take place within the small intestine. There are finger-shaped elevations of the mucous membrane. These are called villi.

The peristaltic reflex is a movement reflex in the intestine. The reflex is triggered by pressure on the mechanoreceptors located in the intestine. The nervous system of the intestine is relatively autonomous, so that the reflex can still be observed in an isolated intestine

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

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
