An ascending tract goes upward. The descending tract goes downward.
central nervous system (CNS) is the descending tract and one ascending tract in upper motor neuron and lower motor neuron.
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.
No, the efferent tract is not the major ascending tract. The efferent tract is responsible for carrying nerve signals away from the central nervous system to muscles or glands, while ascending tracts carry sensory information from the peripheral nervous system to the brain.
The corticospinal tract
No, the corticospinal tract is a direct descending pathway that transmits motor signals from the cerebral cortex to the spinal cord. It is involved in the control of voluntary movements.
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".

reticulospinal
The transverse colon is responsible for absorbing water and electrolytes from digested food, forming and storing feces until elimination. It also helps to move waste material along the digestive tract.
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.
Lateral spinothalamic tract = carry pain and temperature sensationsAnterior spinothalamic tract = carry crude touch and light pressure
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
