Neurite is the term used to describe the cell extension of a nerve cell through which electrical impulses are transmitted to its environment. If the neurite is also surrounded by “glial cells” that isolate it, it is called an axon. Function and structure A neurite is the extension of a nerve cell, and directs its … Neurite
The following additional symptoms may occur Spasticity limits the mobility of the affected muscles. In some patients, spasticity occurs only after prolonged exertion. Many are restricted in their ability to walk. Spasticity is usually accompanied by muscle weakness. Furthermore, a painful feeling of tension or cramps in the muscles can occur. Over a longer period … The following additional symptoms may occur | Spasticity in multiple sclerosis
These drugs are used If exercise therapy is not sufficient to alleviate the symptoms, medication is used. For spasticity, muscle relaxants and anti-epileptic drugs are used. These are intended to relax the muscles. Baclofen or tizanidine is often used in tablet form. In severe cases, muscle relaxants can be given directly into the spinal cord … These drugs are used | Spasticity in multiple sclerosis
Introduction Spasticity is an unintentional tensing of the muscles beyond the normal level. In addition to increased muscle tension, muscle twitches, muscle cramps and muscle rigidity also occur. Spasticity can occur repeatedly in phases or be continuous. They often occur in multiple sclerosis and are often combined with muscle weakness. The spasms can cause pain … Spasticity in multiple sclerosis
White matter can be understood as the counterpart of gray matter in the brain. It consists of conduction pathways (nerve fibers) whose white coloration comes from their medullary structure. The white matter is part of the central nervous system and is also called substantia alba or medulla or medullary substance. In the spinal cord, it … White Matter: Structure, Function & Diseases
Nerve fibers are structures in the nervous system that arise from the cell body of neurons as thin, elongated projections. They act as a kind of conduit by transmitting electrical impulses and enabling interconnectedness between neurons. In this way, information can be processed in the nervous system and commands can be sent to the receiving … Nerve Fiber: Structure, Function & Diseases
Ruffini corpuscles are SA II class mechanoreceptors found in the dermis, the skin of the tooth root, and the joint capsules. The receptors register interoceptive and exteroceptive pressure or stretch and transmit these stimuli to the brain via the spinal cord. Mutations of the receptors are usually associated with insensitivity. What is the Ruffini corpuscle? … Ruffini Corpuscles: Structure, Function & Diseases
Myelin is a fatty substance that surrounds many nerve cells. Since it is spirally wrapped around the nerve cells, the structure that is created is called a myelin sheath. Myelin sheaths are found both in the central nervous system, i.e. in the brain, and in the peripheral nervous system, i.e. in all other nerves that … Myelin sheath
Diseases The most common and best known disease of the myelin sheaths is multiple sclerosis. Here, the human body forms antibodies against precisely these cells that form the myelin sheaths, the oligodendrocytes. These are thereby destroyed. In multiple sclerosis, the myelin sheaths of the central nervous system are affected, i.e. those of the brain and … Diseases | Myelin sheath
