The lateral spinothalamic tract is a bundle of sensory axons ascending through the white matter of the spinal cord, carrying sensory information to thebrain. It carries pain and temperature sensory information to the thalamus of the brain

The white matter tract in the ventral portion of the mid-brain?
spinothalamic tract
What happens if the ventral spinothalamic tract is damage?
The ventral spinothalamic tract carries "light touch" sensation. There are three neurons that carry the information to the brain. From the cutaneous nerve(s) in the skin to the dorsal root ganglia, then to the dorsal horn in spinal cord, crossing over to the other side and traveling up to the thalamus, and finally from the thalamus to post-central gyrus. Because the axons of the neuron cross over to the other side of the spinal cord almost immediately, a spinal cord lesion will produce loss of this sensation on the opposite side of the body below where the lesion occurs. According to one of my medical books, however, light touch can ALSO be carried via the medial lemniscus tract, which doesn't cross until it reaches the brain stem. That being true, light touch could be spared even if there is damage to the ventral spinothalamic tract. I hope that helps! Compliments of your friendly MSI :)
The second order neuron of the spinothalamic system terminates at?
The thalamus
Why is the sense of touch so important?
Crude touch and pressure sensations are functions of the spinothalamic pathway.

What is the difference between lateral spinothalamic and anterior spinothalamic tracts?
Lateral spinothalamic tract = carry pain and temperature sensationsAnterior spinothalamic tract = carry crude touch and light pressure
What tract conducts impulse from the spinal cord to the thalamus?
to the spinothalamic tract
What is the function of lateral spinothalamic tract?
The function of this tract is to detect pain.
What tract conveys nerve impulses for crude touch and pressure?
spinothalamic, it is a somatosensory pathway
The white matter tract in the ventral portion of the mid-brain?
spinothalamic tract
What tract might be damaged if there is diminished pain perception?
The spinothalamic tract is damaged.
What is the pathway for crude pain?
The lateral spinothalamic tract (it carries sensation for temperature and pain) whereas the anterior spinothalamic tract carries sensation for light touch and pressure.
What are the origins for lateral spinothalamic and anterior spinothalamic tracts?
Lateral reticulospinal tract : It arises from the nuclei of reticular formation of the brain stem (mainly medulla)Medial reticulspinal tract : It arises from the nuclei of reticular formation of the brain stem (mainly pons)
Does the spinothalamic tract have somatotopic organisation?
yes the spinothalamic tract is highly organised somatotopically. In the cervical segments (which contain fibres from all levels of the body), fibres from lower levels of the cord (conveying info from legs) are found laterally within the tract; fibres from higher levels (conveying info from arms) are found medially within the tract. i.e ARMS = MEDIAL LEGS = LATERAL Hope that helps =)
