What does PMSN mean in UNCLASSIFIED
Putative Muscular Sympathetic Neurones (PMSN) are a group of neurons found in the peripheral nervous system that are responsible for regulating muscle sympathetic nerve activity (MSNA). MSNA is a measure of the activity of the sympathetic nervous system in skeletal muscle, which is responsible for controlling blood pressure and other cardiovascular functions.
PMSN meaning in Unclassified in Miscellaneous
PMSN mostly used in an acronym Unclassified in Category Miscellaneous that means Putative Muscular Sympathetic Neurones
Shorthand: PMSN,
Full Form: Putative Muscular Sympathetic Neurones

PMSN Function
PMSN are located in the dorsal root ganglia (DRG) of the spinal cord and are activated by sensory input from muscle spindles. Muscle spindles are sensory receptors that detect changes in muscle length and contraction. When a muscle spindle is activated, it sends a signal to the PMSN, which then projects to the sympathetic chain ganglia. The sympathetic chain ganglia then send signals to the blood vessels in skeletal muscle, causing them to constrict and increase blood pressure.
PMSN and Cardiovascular Disease
The activity of the PMSN is increased in people with cardiovascular disease, such as hypertension and heart failure. This increased activity is thought to contribute to the development and progression of these diseases. In hypertension, increased MSNA leads to increased peripheral vascular resistance, which can lead to high blood pressure. In heart failure, increased MSNA can contribute to the development of left ventricular hypertrophy and impaired diastolic function.
Essential Questions and Answers on Putative Muscular Sympathetic Neurones in "MISCELLANEOUS»UNFILED"
What are Putative Muscular Sympathetic Neurones (PMSNs)?
Putative Muscular Sympathetic Neurones (PMSNs) are a type of nerve cell found in the autonomic nervous system. They are located in the dorsal root ganglia of the spinal cord and innervate skeletal muscle. PMSNs are believed to play a role in the regulation of muscle tone and movement.
What is the function of PMSNs?
PMSNs are thought to innervate skeletal muscle fibers and regulate muscle tone and movement. They may also be involved in the regulation of blood pressure and body temperature.
What are the symptoms of PMSN dysfunction?
Dysfunction of PMSNs can lead to a variety of symptoms, including:
- Muscle weakness
- Muscle spasms
- Tremors
- Difficulty with movement
- Changes in blood pressure
- Changes in body temperature
How are PMSNs diagnosed?
PMSNs are diagnosed based on a physical examination and a medical history. Additional tests, such as electromyography (EMG) and nerve conduction studies, may be used to confirm the diagnosis.
How are PMSNs treated?
Treatment for PMSN dysfunction depends on the underlying cause. Medications, such as muscle relaxants and anticholinergics, may be used to relieve symptoms. In some cases, surgery may be necessary.
Final Words: PMSN are an important part of the sympathetic nervous system that play a role in regulating blood pressure and cardiovascular function. Increased activity of the PMSN is associated with cardiovascular disease, and targeting the PMSN may be a potential therapeutic strategy for these diseases.
