It is important for human mineral metabolism to take in enough of the required minerals with food. People need larger amounts of some minerals. That is why they are also called set elements in nutritional science

Nerve conductivity is the ability of nerve fibers to transmit bioelectrical impulses in both directions at a certain speed. The forwarding takes place via action potentials in the severability stimulus line

The term eustress stands for "positive stress", while dysstress means "negative stress". Both terms are often used in connection with stress management. Stress is not always harmful to the human organism, but rather

The Mendel-Bechterew reflex is a foot reflex from the Babinski group, which is counted among the pyramidal signs. The pathological reflex movement can indicate damage to the central motor neurons. Such damage arises

The Oppenheim reflex or the Oppenheim sign is a natural reflex in babies and a pathological reflex in adults. Neurology associates this reflex movement with the signs of the pyramidal trajectory, as is the case with damage to central motor neurons

The physician understands the cremaster reflex to be the polysynaptic external reflex of the cremaster muscle, which moves the testicles upwards in response to stimuli. The reflex is exhaustive and can therefore be absent due to age-physiology. An abnormal reflex behavior

The Piotrowski reflex is a foot reflex of the tibialis anterior muscle. Physiologically, it is weak or nonexistent. An increased reflex movement can indicate neurological damage in the pyramidal tracts of the spinal cord.

The dorsal reflex is a pathological self-reflex of the plantar interossei muscles and is one of the pyramidal signs. In a healthy adult, the reflex plantar flexion of the toes with one blow on the dorsal side of the foot is hardly possible

Platelet adhesion is part of hemostasis in which platelets attach to collagen. This step activates the platelets.

Pubescence refers to male puberty. The boy reaches sexual maturity and then enters puberty, during which secondary male body features develop and the psyche evolves into the adult stage.

The infant phase is the first phase of a child's life from birth to the first year of life. It goes through a very eventful physical and mental development and is mostly suckled by the mother during this period.

Just like fine motor skills, gross motor skills are a movement function of the human body. Gross motor movements are accompanied by movement of the whole body, e.g. when jumping or running.

The toddler phase is the period between the 1st and 5th year of life. This phase in the child's life has a strong impact on the rest of life. The toddler makes a tremendous mental as well as emotional and physical

Almost everyone who has reached puberty knows the famous "butterflies in the stomach". They describe a feeling that puts the body in a completely exceptional state and mostly overrides rational thinking - being in love

Individuation is the development of one's own abilities and the search for one's own values. The term is often synonymous with self-realization. The conflict of individuation vs. Dependence is seen as a major source of mental illness

The refractory period is the phase in which neurons cannot be re-excited after an action potential has occurred. These refractory phases prevent the retrograde spread of excitation in the human body. There is one in cardiology

The inhibitory postsynaptic potential is an inhibitory signal. It is formed by the postsynaptic termination of a synapse and leads to a hyperpolarization of the membrane potential. This means that there is no new action potential from this nerve cell

The excitatory postsynaptic potential is an exciting potential in the postsynaptic membrane of neurons. The individual potentials are summed up spatially and temporally and can thus create an action potential. Transmission st

The saltatory conduction of excitation ensures that the conduction speed of nerve tracts is sufficiently fast for vertebrates. Action potentials jump from one unisolated ring to the next on the isolated axons. For demyelinating diseases

Transcytosis is a type of substance transport in which a certain substance is absorbed into the cell via endocytosis and released back into the extracellular space via exocytosis. Transcytosis is controlled by receptors and takes place mainly in the epithelium
