Question

Make a table with the similarities and differences between dorsal column medial lemniscal and spinothalmic pathways.

Answer 1

Similarities between dorsal column medial lemniscal pathway and spinothalamic pathway:-

• Both are connects to the primary somatosensory cortex
• Have three order neurons
• Third order neurons starts from thalamus

Difference:-

Dorsal column medial lamniscal pathway	Spinothalamic pathway
First order neuron receives stimulus from proprioceptors or from mechanoreceptors	First order neuron receives stimulus from nociceptors or from thermoreceptors
Second order neurons starts from medulla oblongata	second order neuron starts from spinal cord
There is synapse at medulla oblongata	second order neuron directly connects to thalamus through medulla oblongata
Neurons passes through dorsal horn of the spinal cord	neurons passes from anterolateral quadrant of the spinal cord.
First synapse at medulla oblongata	First synapse at dorsal horn of the spinal cord
