What is media lemniscus?
Medial lemniscus, also called reil 檚 檚 檚 belt or ribbon, is a channel for sensory data for thalamus from the kernel of gracil and cuneate in the brain. Almost all skin mechanoreceptors in the body that transmit information about light touch, vibration and pressure signposts will go through the media path of the dorsal column. It starts in Medulle, travels to pony and eventually ends up in midbrain.
Sensory information is collected by gracil and core Cuneate and transmitted to thalam using media lemniscus. The cores of gracile and cuneate are also known as the cores of the dorsal column. The gracile tract is the location of axon fibers that transmit information about the lower limb. Cuneate tract is located side in gracile tract and is a place of axon fibers for chest, neck and upper limbs. Above the Gracile and Cuneate core in the lower closed part of the Medully is a place where the media lemniscus begins, no matter what is not fully formed until the open medulla further on the brain stem.
neurons placed in the cores of dorsal columns transmit Axons to the thalamus that interpret somatic sensory information from the body; Axons are designed into the back of the bottom of the brain stem. Once the axons branch into this area, the inner arch forms. The fibers then exceed the middle molding of the brain stem in a process called Decussation and create a path called Medial Lemniscus. Axons of transmitting information from the lower limbs of the body are located in the ventral part of the media lemniscus; Axons for the upper limbs of the body are stored in the dorsal part of the structure.
When the ribbon of the media lemniscus travels up in the pasty and the middle brain, it turns on the side at an angle of 90 degrees. Once it turns, axons are stored different places. The side part will contain axons for the lower limbs of the body and the middle part will hold the axons of the upper body. It continues to rise to the brain until it reaches Thalamus's ventralthe rear core (VPL).
Damage to the media path of the dorsal column can cause problems with the ability of a person 檚 檚 to detect tactile stimuli. The person may also have difficulty feeling the position of his arm and legs. The inability of the damaged track to process the speed and direction of touch may cause one to be able to find out which letters and numbers are traced to the skin during diagnostic testing.
