Is the descending colon the first part of the large intetine?
The ascending colon is the first part of the large intestine. The descending colon is the part of the colon that is found at the end of the colon in digestive tract anatomy.
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.
Is corticospinal tract an indirect descending tract?
no
Is the efferent tract the major ascending tract?
YES
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
What track is the major descending voluntary motor tract?
The corticospinal tract
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".

Which of the following is not an ascending spinal cord nerve fiber tract?
reticulospinal
The pyramidal tract is the major descending voluntary motor tract?
the corticospinal tract and the pyramidal spinal tract are the same tract. yes this tract is the main voluntary motor tract, remember that this tract split in two after the decussation of pyramids (hence the term pyramidal tract) the fibres that do decussate create the lateral portion which innervates the limbs, shoulders and neck the fibers that dont decussate here continue ipsilaterally creating an anterior/ventral portion which innervate the truck, these eventually do decussate at their spinal exit level
Descending tracts within the spinal cord carry what kind of impulses to the muscles?
To make it simple, they are 3 types of descending (efferent) tracts of spinal cord:Pyramidal tracts = lateral and anterior corticospinal tracts + corticobulbar tractExtra-pyramidal tracts= Vestibulospinal + Reticulospinal (Lateral and medial) + Olivospinal + Rubrospinal + Tectospinal tractsDescending autonomic
