A nerve fiber is a portion of a nerve. A nerve is composed of several nerve fiber bundles. These nerve fiber bundles contain many nerve fibers. Each nerve fiber is surrounded by the so-called endoneurium, a kind of protective mantle around each nerve fiber. The endoneurium consists of connective tissue and elastic fibres and because … Nerve fiber
Markless nerve fibers Markless nerve fibers can be found mainly where information does not have to be passed on so quickly. For example, pain nerve fibers that transmit information about pain sensation to the brain are partially markless. This is important because, for example, there is pain that has to last a long time. In … Markless nerve fibers | Nerve fiber
Nerve fiber quality Nerve fiber quality is used to describe from which part of the body information is passed on. On the one hand, there are the somatosensory nerve fibers, which are also called somatoafferent. Somato refers here to the body, sensitive or afferent, refers to the fact that the information is transmitted from the … Nerve fiber quality | Nerve fiber
The falx cerebri separates the two hemispheres in the cerebrum. It is a crescent-shaped membrane. It is composed of hard meninges. What is the falx cerebri? The falx cerebri is classified as part of the central nervous system and is located inside the skull. The cerebrum consists of two halves. These are also called hemispheres … Falx Cerebri: Structure, Function & Diseases
Products Metoclopramide is commercially available in tablet, solution, and solution for injection (Primpéran, Paspertin). It has been approved in many countries since 1967. The drops and suppositories for children were withdrawn from the market in November 2011 because of the risk for extrapyramidal side effects. Structure and properties Metoclopramide (C14H22ClN3O2, Mr = 299.8 g/mol) is … Metoclopramide
Synonyms Medical: Nervi spinal spinal nerves, CNS, spinal cord, brain, nerve cell Declaration Humans possess 31 pairs of spinal nerves (spinal cord nerves), which pass between the individual vertebrae through the intervertebral holes, i.e. (almost) analogous to the division of the spinal cord on each side: this uniform structure can give the impression of segmentation, … Spinal Cord Nerves
Ignition A direct inflammation of the spinal nerve (spinal nerve) is not an independently described clinical picture, but an inflammation of a nerve root in the area of the spinal cord can occur.The spinal nerve is formed by the union of both nerve roots, the anterior and posterior root; if there is an inflammation of … Ignition | Spinal Cord Nerves
Symptoms of a lesion If there is a lesion of a spinal nerve or one of the two nerve roots located just before this nerve, this can cause symptoms that can give an indication of the location of the lesion. The primary characteristic is that if only one spinal nerve is affected, the symptoms are … Symptoms of a lesion | Spinal Cord Nerves
Products In many countries, there are no products with benzphetamine on the market. The active ingredient belongs to the narcotics. Benzphetamine is available in the USA, for example (e.g. Didrex). Structure and properties Benzphetamine (C17H22ClN, Mr = 275.8 g/mol) is present in drugs as benzphetamine hydrochloride, a white crystalline powder that is soluble in water. … Benzphetamine
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
