Brain motor cortex pathways, artwork C016 / 6531
Brain motor cortex pathways. Artwork of a lateral (from the side) view of a human brain, showing neural pathways (pink lines) from the motor cortex of the brain to the brainstem and spinal cord. These pyramidal pathways are the corticospinal and corticobulbar tracts. The former controls conscious movement of the upper limbs, body and legs. The latter controls face, neck and head muscles. The pathways arise in the primary motor cortex (coloured areas) in the frontal lobe and on its border with the parietal lobe. The red lines indicate the sections shown in C016/6532. From top to bottom, the horizontal lines are at the level of the: mid brain, pons, medulla, and spinal cord

EDITORS COMMENTS
This photo print, titled "Brain motor cortex pathways" offers a fascinating glimpse into the intricate neural connections within the human brain. Presented in a lateral view, this artwork showcases the pink lines representing the pyramidal pathways that extend from the motor cortex to both the brainstem and spinal cord. The corticospinal and corticobulbar tracts, depicted by these neural pathways, play crucial roles in controlling conscious movement throughout our body. The former governs voluntary actions of our upper limbs, body, and legs while the latter regulates facial expressions, neck movements, and head muscles. Originating from colored areas within the frontal lobe bordering with the parietal lobe known as primary motor cortexes, these pathways are highlighted against a white background for clarity. Additionally, red lines indicate specific sections shown in C016/6532. As we trace these horizontal lines from top to bottom on this mesmerizing illustration printout - midbrain, pons (part of brainstem), medulla (medulla oblongata), and finally reaching down to our spinal cord - we gain insight into how signals travel through various regions of our central nervous system. With its emphasis on anatomy and physiology combined with elements of biology and neurology research fields – this artwork serves as an invaluable resource for scientists studying healthy brain function or neurological disorders.
