What is the function of white matter in the spinal cord?
The function of white matter in the spinal cord is to convey information from the nervous system to the brain or from the brain to the systems. The spinal cord is made of gray matter and white matter. The gray mass is in the middle of the spinal cord, with four corners branching from each corner, which resembles the letter H and surrounded by white matter. Four corners are called dorsal corner, side corner, middle column and column of ventral corner. Both white and gray matter contain bundles of nerve fibers, called neurons that mediate pulses between the peripheral nervous system and the central nervous system.
White matter contains neurons that carry nerve pulses. These neurons are covered with a myelin cloak. The cord connects the brain to the rest of the body through the central nervous system and sends information along these nerve fibers to function properly.
Free packages contained in white Matter are called axons. Are covered with myelin, which is mostly lipid tissue full of capillaries that isolate axons and helps Je accelerate. The fiber bundles contained in the gray matter are called dendrites and are covered with synapses. Axons are grouped into tracts that carry similar information.
Some tracts carry information from white matter in the spinal cord to the brain and are called ascending tracts. These tracts are responsible for informing the brain what the fingers or other parts of the body feel. Other tracts travel from the brain to other parts of the body and are called descending tracts. They can give orders to move muscles or to the internal organs to perform their functions. It is a function of neurons in Misha to communicate information that either rises to the tract or falls down the tracks.
gray matter provides communication between the central nervous system and the peripheral nervous system that leans the nerves outside the backbone column, which serves other areas of the body. Neurons in gray matter are non -perelinated, so they travel in white more slowly than myelinated axons.
