Where do motor neurons decussate?
decussation of pyramids
Where does decussation of the pyramids occurs in the brain?
medulla oblongata
What is the term used to describe the crossing over of a tract to the side of the nervous system opposite to where the axons originated?
Decussation
Because of the decussation of sensory nerve fibers the right postcentral gyrus monitors sensations from the left side of the body?
true
Which hemisphere would register a touch on the left hand?
The right side of the brain controls the left side of the body because most fibers in the brain crossover (decussation) at the medulla oblongata.
What does the term 'decussation' mean and where does it occur?
decussation = cross over and occurs mainly in the medulla oblongata
Where do motor neurons decussate?
decussation of pyramids
Where does decussation of the pyramids occurs in the brain?
medulla oblongata
The pyramids of the medulla oblongata are the sites of?
decussation of nerve tracts
What is the scientific name for nervous pathway switching sides?
decussation
Why does decussation takes place in brain?
There is considerable variation in the extent to which decussation takes place in the medulla oblongata; about two-thirds or three-fourths of the fibers usually decussate in the medulla oblongata and the remainder in the medulla spinalis.
Which of the following does NOT describe the spinal cord tracts pathways?
memory. it does have relay, somatotype and decussation
Where does decussation take place?
Decussation typically takes place in the brainstem and spinal cord, where nerve fibers cross over from one side of the central nervous system to the other. This crossing is important for coordinating movements and sensory information between the brain and body.
What is the term used to describe the crossing over of a tract to the side of the nervous system opposite to where the axons originated?
Decussation
What does NOT describe the spinal cord tracts pathways a decussation b somatotopy c relay d memory?
D) Memory
Because of the decussation of sensory nerve fibers the right postcentral gyrus monitors sensations from the left side of the body?
true
What is the definition of the four lemnisci that can be found in the pons?
They are four bands of ascending sensory fibres in the brain stem. Each lemniscus starts from a decussation below and ends in the thalamus above.
