The systolic blood pressure is the blood pressure peak in the arterial part of the body's circulation, which is caused by the contraction of the left ventricle and which, when the aortic valve is open, enters the aorta and its branches into the arteries

Accommodation is the ability of the eye to dynamically adjust the refraction of light and for this reason to recognize objects clearly and sharply from any distance.

Oxidative decarboxylation is a component of cell respiration and takes place in the cell's mitochondria. The end product of the oxidative decarboxylation, acetyl-coA, is then processed further in the citric acid cycle.

A short-term change in the membrane potential is called an action potential. Action potentials typically arise on the axon hill of a nerve cell and are the prerequisite for stimulus transmission.

The gastrocolic reflex is an irritant response of the large intestine that occurs when the stomach is irritated. The gastrocolic reflex causes the large intestine to contract and the contents of the large intestine are advanced towards the rectum.

The hydrogen bond is an interaction between molecules that is similar to the Van der Waals interactions and occurs in the human body. The bond plays mainly in the context of peptide bonds and chains of amino acids

In the stretch-shortening cycle (DVZ), an eccentric stretching of a muscle is followed by a concentric contraction of the same muscle, which is energy-saving and uses the kinetic energy from the stretching. The DVZ plays an important role

Reactive force is a form of rapid force based on the stretching-shortening cycle. The cycle is an active lengthening of the muscles, followed by a contraction of the same muscles. The reactive force is abolished or restricted

The patellar tendon reflex corresponds to the monosynaptic kneecap reflex and is triggered by pressure on the patellar tendon. The thigh muscles contract as part of the involuntary self-reflex movement and the lower leg snaps afterwards

The semantic memory is part of the declarative memory and contains objective facts about the world that are coded via certain interconnections of the synapses in the temporal lobe. Among other things, the hippocampus is involved in the expansion of semantic memory

The neural plasticity spans various remodeling processes of the nerve cells, which represent an essential condition for learning experiences. The reconstruction of synapses and synapse connections takes place until the end of life and takes place in dependence

Fetogenesis is the term used to describe the biological development of the fetus. Fetogenesis follows on from embryogenesis and begins around the ninth week of pregnancy. Fetogenesis ends with birth in the ninth month of pregnancy.

The acceleration corresponds to a somatic or psychological development acceleration.

The involution of embryogenesis is a basic movement of gastrulation. In addition, in medicine, involution often stands for the natural regression of tissue with age. In pathophysiology there is a pathological regression

Ingression or immigration is a cell movement of gastrulation and thus constitutes an embryonic development step. Cells of the prospective endoderm, i.e. those of the outer cotyledon, migrate into the blastula. Cell movement errors

The formation process and the formation of the teeth is called odontogenesis. More precisely, it is understood to mean the period in which the first appendages of the milk teeth are formed and the teeth of the permanent dentition erupt, including the

Forgetting is a natural process that increases with age. Forgetting also helps to maintain mental health, because it is impossible for us to remember everything we see, hear, taste, smell and feel.

The receptor potential is the response of sensory cells to a stimulus and generally corresponds to a depolarization.It is also called generator potential and is a direct result of the transduction processes with which the receptor generates a stimulus

Fracture healing is the healing of a bone fracture. A distinction is made between primary and secondary fracture healing. Disturbances in this process can lead to pseudarthrosis.

Alkylation marks the transfer of an alkyl group from one molecule to another. Alkylation has a mutagenic and carcinogenic effect, because DNA and RNA are often attacked and changed by alkylating agents. The so-called alkylating agents
