Where does motor impulse travel through spinal cord?
ascending tracts
What is the difference between ascending tracts and descending tracts of the spinal cord?
ascending carry sensory information toward the brain.descending convey motor command to the spinal cord.
Do descending fiber tracts of the spinal cord carry sensory or motor information?
The ascending tracts carry information to the brain.
The anterior root of the spinal cord is composed of?
motor fibers
What fibers do ventral spinal cord roots contain?
The ventral roots contain motor fibers.
What part of the spinal nerve consists of motor fibers leaving the spinal cord?
The ventral root.
What part of a spinal nerve contains only efferent fibers?
The ventral root of the spinal nerve has the efferent fibers and the dorsal root has the afferent. Prior to joining each other in the spine they each consist of only those fibers.
What type of fibers make up the posterior and anterior roots of the spinal nerve?
Both Afferent and Efferentboth sensory and motorContains motor & sensory fibers!The spinal cord consists of nerve fibers that are afferent and efferent.
What two tracts do the spinal cord have?
ascending (sensory/afferent) and descending (efferent/motor) tracts.Addition: Other than these two types of tracts, the white matter of spinal cord also contains "associative tracts" containing short ascending and descending fibres which coordinate the function of the different regions of spinal cord.
Does the dorsal ramus consist only of motor fibers bringing information to the spinal cord?
False.
What type of nerve fibers are found in the ventral ramus of a spinal nerve?
Both sensory and motor
What is the function of the medula oblongata?
it extend the spinal cord through four fifth of the spinal column
