Descending tracts within the spinal cord carry what kind of impulses to the muscles?

∙ 12y ago
To make it simple, they are 3 types of descending (efferent) tracts of spinal cord:
- Pyramidal tracts = lateral and anterior corticospinal tracts + corticobulbar tract
- Extra-pyramidal tracts= Vestibulospinal + Reticulospinal (Lateral and medial) + Olivospinal + Rubrospinal + Tectospinal tracts
- Descending autonomic

Do descending fiber tracts of the spinal cord carry sensory or motor information?
The ascending tracts carry information to the brain.
Are extrapyramidial tracts nerve tracts that the corticospinal tracts that transmit impulses into the spinal cord?
yes it is
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.
What tracts of the spinal cord carry impulses away from the brain?
synape
Primary motor area sends impulses via to control skeletal muscles?
The primary motor cortex send nervous impulses via the pyramidal cells, down the pyramidal tracts in the spinal cord.
What impulses do ascending tracts within the spinal cord carry to the brain?
reflex
Which spinal cord tracts carry impulses for conscious sensations?
Lateral Spinothalamic
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.
In the spinal cord white matter is separated into ascending and descending tracts organized as?
columns
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.
What is the test you performed that involves the stimulation of ascending and descending spinal cord tracts?
the Babinski Test
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".
