What is descending tract and one ascending tract in upper motor neuron and lower motor neuron?
central nervous system (CNS) is the descending tract and one ascending tract in upper motor neuron and lower motor neuron.
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.
Is the efferent tract the major ascending tract?
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.
What track is the major descending voluntary motor tract?
The corticospinal tract
Is corticospinal tract an indirect descending 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.
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
Function of the transverse colon?
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.
What carries sensory information to the spinal cord?
Sensory neurons carry sensory information from various parts of the body to the spinal cord. These neurons transmit signals like pain, temperature, touch, and other sensory inputs to the central nervous system for processing and response.
What is the difference between lateral spinothalamic and anterior spinothalamic tracts?
The lateral spinothalamic tract carries pain and temperature information, while the anterior spinothalamic tract carries crude touch and pressure information. The fibers in the lateral spinothalamic tract cross over to the opposite side of the spinal cord before ascending, whereas the fibers in the anterior spinothalamic tract cross over at the level they enter the spinal cord.
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
