Answer: Features of Lemniscal pathway: This is pathway mainly involved in the sensory ascending pathways to process sensation & perception through a 3 neuron system finally enable “sensory information” to the central nervous system through sensory receptor to the cortex. This pathway is mainly involved in mediating discriminative touch sensation through adequate proprioception & vibration. This pathway has two white matter tracts profoundly possess a first neuron mainly through fasciculus gracilis in the medial column from lower limb (T6 and lower) & sensory information is obtained through fasciculus cuneatus: of lateral column in upper limb (T5) Features of spinothalamic pathway: This is the sensory pathway mainly involved in processing sensory information of “poorly localized touch, pressure & temperature”. This pathway is going to involve cross of sensory information to the spinal cord prior to ascending via the anterior or spinothalamic & lateral spinothalamic tracts. Interaction of these two pathways: The interaction of these two pathways are mainly through axons & spinaothalamic tracts arising into an ascending pathway to transport to the sensory information processing center in the brain. Mainly spinothalamic neurons are going to use first order neurons, second order neurons, third order neurons to enter spinal cord and synapse through posterior gray horns & these neurons are going to carry sensory information of pain, sensation etc in ventral nucleus group of the thalamus. This information is going to reach through from the Lemniscal pathway finally relayed onto the primary sensory cortex.

1. Answer:
Features of Lemniscal pathway: This is pathway mainly involved in the sensory ascending
pathways to process sensation & perception through a 3 neuron system finally enable “sensory
information” to the central nervous system through sensory receptor to the cortex. This pathway
is mainly involved in mediating discriminative touch sensation through adequate proprioception
& vibration.
This pathway has two white matter tracts profoundly possess a first neuron mainly through
fasciculus gracilis in the medial column from lower limb (T6 and lower) & sensory information
is obtained through fasciculus cuneatus: of lateral column in upper limb (T5)
Features of spinothalamic pathway: This is the sensory pathway mainly involved in processing
sensory information of “poorly localized touch, pressure & temperature”. This pathway is going
to involve cross of sensory information to the spinal cord prior to ascending via the anterior or
spinothalamic & lateral spinothalamic tracts.
Interaction of these two pathways: The interaction of these two pathways are mainly through
axons & spinaothalamic tracts arising into an ascending pathway to transport to the sensory
information processing center in the brain. Mainly spinothalamic neurons are going to use first
order neurons, second order neurons, third order neurons to enter spinal cord and synapse
through posterior gray horns & these neurons are going to carry sensory information of pain,
sensation etc in ventral nucleus group of the thalamus. This information is going to reach through
from the Lemniscal pathway finally relayed onto the primary sensory cortex.
