The cause of psoriasis remains largely a mystery. But it's likely that the interplay between genes and triggers is a big part of the story. Researchers believe that psoriasis develops when something mistakenly triggers the immune system. And in psoriatic arthritis -- psoriasis that affects the joints -- both genetics and environmental factors seem to play a role.
The parasympathetic nervous system helps regulate heart rate by slowing it down. It works in opposition to the sympathetic nervous system, which speeds up heart rate.
Naturally, the nervous system needs nutrients (particularly oxygen) to keep it's cells alive and functional, just like any other system.
I've suffered some damage to my central nervous system.
The human nervous system does not play a direct role in removing wastes from the body. Waste removal is primarily carried out by the urinary system, respiratory system, digestive system, and integumentary system.

The fundamental building block of the nervous system is the neuron. Neurons are specialized cells that transmit information throughout the body via electrical and chemical signals. They play a crucial role in enabling communication within the nervous system.
In the developing fetal nervous system, the development of sensory neurons requires the actions of signaling molecules like growth factors and transcription factors. These molecules help regulate the differentiation of neural progenitor cells into mature sensory neurons and guide the growth of axons towards their targets. Additionally, interactions with surrounding cells and the extracellular matrix play a crucial role in the proper development of sensory neurons.
The conductive cells of the nervous system are called neurons. Neurons are specialized cells that are capable of transmitting electrical impulses and information throughout the body. They play a vital role in processing and transmitting signals in the nervous system.
The digestive system is related to the nervous system in such a way that the nervous system dictates the speed of breaking down of food. The nervous system overseas activity in the digestive tract, and regulates secretion if there are changes.
No, ganglia are not organs. They are clusters of nerve cell bodies located outside of the central nervous system. Ganglia are part of the peripheral nervous system and play a role in transmitting signals between the central nervous system and various parts of the body.
