They are sensory tracts.
We have 4 tracts carrying conscious sensations = gracile + cuneate + lateral spinothalamic + anterior spinothalamic
Another 4 tracts carrying unconscious sensations = posterior spinocerebellar + anterior spinocerebellar + spino-olivary + spinotectal

What type of signal travels through the ascending spinal tracts?
sensory
What carries sensory information to the spinal cord?
The major descending motor tract FROM the cerebrum is the corticospinal tract. The major ascending sensory tracts TO the cerebrum are the sensorimotor tract and the dorsal column lemniscal system.
What are intersegmental tracts?
They are short ascending and descending fibres which connect the various segments together to integrate their activities. They include:Fasciculi propriiseptomarginal and coma-shaped tractsAnterior intersegmental tractLissauer tract
Is the ascending colon lateral to the urinary bladder?
The ascending colon is lateral to the urinary bladder.
What is pyramical tracts?
They are those whose fibers come together in the medulla to form the pyramids. They also have another name-corticospinal 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.
What kinds of nerves are in the upward tract and downward tract of the spinal cord?
The ascending tracts (upward) contain sensory nerves, that pass sensory information from the body to the brain. The descending tracts (downward) contain motor nerves that activate the muscles in the body according to the brain's "commands".

Where does motor impulse travel through spinal cord?
ascending tracts
What impulses do ascending tracts within the spinal cord carry to the brain?
reflex
In the spinal cord white matter is separated into ascending and descending tracts organized as?
columns
Why do messages not get mixed up passing through the spinal cord?
There are ascending and descending tracts in the spinal cord. These tracts are nerve fibers bundled together. Messages going to the brain pass through the ascending tracts while messages coming from the brain pass through the descending tracts. These separate paths prevent messages from getting mixed up.
Do descending fiber tracts of the spinal cord carry sensory or motor information?
The ascending tracts carry information to the brain.
What is the test you performed that involves the stimulation of ascending and descending spinal cord tracts?
the Babinski Test
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.
The funiculi all contain what?
nerve tracts
