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
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
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
Synonyms Spinal cord nerves, spinal nerves Medical: Medulla spinalis (medulla = lat. medulla, spinal = lat. spiny, thorny, belonging to the spinal cord), myelon (= Greek medulla), Definition The spinal cord is the lower part of the central nervous system (CNS), which runs inside the spinal canal and is responsible for the motor (movements) and … Spinal cord
Structure The spinal cord is a symmetrical reflex organ, i.e. divided into two similar halves (=bilateral) and, in contrast to the brain, has a relatively original and simple structure, which in principle looks the same in its various sections. Analogous to the spinal column, it can be divided into the breech or coccygeal marrow, which … Structure | Spinal cord
Situation development In infants, the spinal cord still fills the spinal canal up to the lower lumbar vertebrae, in children it reaches up to the 4th lumbar vertebra. This must be taken into account when withdrawing nerve fluid; one must then enter the spinal canal further down in order not to endanger the spinal cord. … Situation development | Spinal cord
Diseases of the spinal cord Basically, it has to be said that the pattern of failures that occurs depends on where exactly in the spinal cord there is damage. Even without imaging diagnostics such as CT (computed tomography) or MRI (magnetic resonance imaging), the clinical image can provide very useful information in this regard based … Diseases of the spinal cord | Spinal cord
Synonyms Spondylodiscitis, infectious spondylodiscitis, spondylitis, osteomyelitis, spondylitis Introduction Spondylodiscitis or spondylitis is generally understood to be the inflammation of the intervertebral disc and surrounding soft tissues such as the base and top plate of the spinal segment. Osteomyelitis of a vertebral body caused by non-specific pathogens is distinguished from inflammation caused by specific pathogens. Specific … Inflammation of the cervical vertebrae
Symptoms Patients express particularly severe back pain in the acute phase of the inflammation. They describe this pain as throbbing and pulsating, as well as a feeling of congestion and pressure in the area of the affected vertebral body segment. Often the pain increases with movement, especially the turning and tilting of the head leads … Symptoms | Inflammation of the cervical vertebrae
