Grasping is an automated movement pattern that is planned in the motor cortex of the brain. From there, the movement plan for reaching is transmitted to the voluntary muscles via the brain‘s pyramidal pathways. Impaired reaching movement may indicate neurodegenerative diseases. What is reaching? Grasping is an automated movement pattern that is planned in the … Grasping: Function, Task & Diseases
The Strümpell sign is a co-movement of the toes when the knee joint is flexed against resistance. This movement is physiologic in children under one year of age. However, in adults, it is evaluated as a pyramidal tract sign and refers to damage to the central motor neurons. What is the Strümpell sign? The Strümpell … Struempell Sign: Function, Task & Diseases
Reactive strength is a form of high-speed strength that has the stretch-shorten cycle as its basis. The cycle is an active lengthening of muscles followed by contraction of the same muscles. Suspended or limited, reactive strength occurs, for example, in neuromuscular diseases. What is reactive force? Reactive force is needed by humans to perform forms … Reactive Force: Function, Tasks, Role & Diseases
The so-called clivus edge syndrome describes a main clinical feature as a result of a horizontal displacement of the brainstem in the upper region. In the tentorial slit, the oculomotor nerve is thereby damaged by increased pressure. The cause of this is subdural hematoma following cerebral hemorrhage or cranial trauma. What is clivus edge syndrome? … Clivus Edge Syndrome: Causes, Symptoms & Treatment
Definition A myelopathy is damage to the nerve cells of the spinal cord. The medical term is formed from the two ancient Greek words myelon – marrow and pathos – suffering. Depending on the cause of the damage to the spinal cord, a distinction is made between different forms. The location of the spinal cord … Myelopathy
Diagnosis Anamnesis already provides indications of a myelopathy. It is important to ask about specific symptoms such as paralysis, sensitivity disorders or pain in the spinal column. The clinical examination provides further certainty, as reflexes can be conspicuous, for example, and the gait pattern can be altered. To confirm the diagnosis, magnetic resonance imaging is … Diagnosis | Myelopathy
History The course of a myelopathy can be very different depending on the cause. A basic distinction is made between an acute and a progressive form. Acute means occurring quickly or suddenly, which is manifested by sudden development of the symptoms.The cause can be, for example, bleeding into the spinal canal after a trauma. Furthermore, … History | Myelopathy
Synonyms nerve damage, nerve lesion, nerve injury Classification of nerve damage Nerve damage is classified according to the location of the injury, so one distinguishes an additional nerve damage can be distinguished according to the type of damage: Central nerve damage in the area of the central nervous system and Peripheral nerve damage located outside … Nerve damage
Healing time of a nerve damage The healing time of a nerve damage depends primarily on the extent of the damage. Minor damage, which only resulted in damage to the nerve sheath, usually heals within a few days. If the nerve is not completely severed, it can also take only a few weeks before the … Healing time of a nerve damage | Nerve damage
When is the nerve dead? There are two scenarios that can lead to a nerve not being able to regenerate after damage, so it is “dead”. The “dying” of the nerve usually manifests itself in the abrupt subsidence of the previously existing nerve pain or acute paralysis. A possible cause for the death of a … When is the nerve dead? | Nerve damage
Innervation connects organs, tissues, and body parts to the nervous system, enabling complex interactions within the body. Electrical and biochemical stimuli are transmitted through the nerve cells and nerve fibers. Damage to nerve structures can result in motor dysfunction, insensations, and even life-threatening consequences. What is innervation? In medicine, innervation is the functional supply network … Innervation: Function, Tasks, Role & Diseases
