How do the Dorsal Column and Anterolateral pathways compare in terms of function?
Understand the Problem
The question is asking us to compare the Dorsal Column and Anterolateral pathways, specifically focusing on their functions and the similarities or differences in how they operate within the nervous system.
Answer
The DCML carries fine touch, vibration, and proprioception, while the anterolateral pathway carries pain, temperature, crude touch, and pressure.
The dorsal column-medial lemniscus pathway (DCML) carries information about fine touch, vibration, and proprioception, while the anterolateral (spinothalamic) pathway mediates pain, temperature, crude touch, and pressure.
Answer for screen readers
The dorsal column-medial lemniscus pathway (DCML) carries information about fine touch, vibration, and proprioception, while the anterolateral (spinothalamic) pathway mediates pain, temperature, crude touch, and pressure.
More Information
The dorsal column-medial lemniscal pathway decussates in the medulla, while the anterolateral pathway decussates in the spinal cord.
Tips
A common mistake is confusing the sensory modalities they carry. Remember that the DCML is mainly for fine touch and the anterolateral for pain and temperature.
