Synonym nerve cells, neurons, lat. : nerve, -i Definition Neurons are nerve cells and therefore part of the nervous system. They serve the Recording, Processing and Forwarding of information. A nerve cell consists of a cell body (perikaryon or soma) and extensions. There are two types of extensions: Dendrites and Axons. Physiology Information is transmitted … Nerves
Excitation line In order for the information to spread along the nerve cell and be transmitted over long distances, action potentials must be generated along the nerve again and again. Two forms of excitation conduction can be distinguished: In saltatory conduction, parts of the nerve are so well isolated in regular sections that the excitation … Excitation line | Nerves
Central and peripheral nerves A distinction is made between a central nervous system (CNS) and a peripheral nervous system (PNS) and thus also between central and peripheral nerve cells. The nerve cells of the CNS include, for example, the motoneurons, which are found in both the brain and the spinal cord. In terms of numbers, … Central and peripheral nerves | Nerves

This means that the disease is not inherited, but is triggered spontaneously by errors in the carrier’s DNA. The sequence of certain compounds in the DNA, so-called base pairs, determines the blueprint of … Causes | Sturge Weber Syndrome
The retina is located on the back of the inner wall of the eye and is instrumental in creating image information for the brain. Age, disease, and congenital disorders can impede the function of the retina, which has a complex structure, in many ways. A large number of successful therapeutic procedures exist. What is the … Retina: Structure, Function & Diseases
Definition – What is a neurotransmitter? The human brain consists of an almost unimaginable number of cells. An estimated 100 billion neurons, which carry out the actual thinking work, and once again the same number of so-called glial cells, which support the neurons in their work, form the organ that makes us humans something special … Neurotransmitter
GABA The amino acid glutamate is known to most people as a food additive and flavor enhancer in a variety of ready meals. However, glutamate is much more important for us as the most important excitatory neurotransmitter in our nervous system. In a way, glutamate is therefore the antagonist of GABA. However, the two messenger … GABA | Neurotransmitter
