Pyramidal tracts is the term used to define two distinct collections of efferent nerve fibers: the corticobulbar tract and costicospinal tract.

We all know that our muscles are, of course, innervated by nerves, however, nerves only run from the spinal cord to their respective muscles, right?! How does a signal from the motor cortex in our brain make it all the way down to the spinal cord? Is there some kind of ‘motor signal’ highway running from the brain that we should know of? • In the full version of this tutorial we are going to take a look at one of the major pathways for voluntary motor signals, which are commonly known as the pyramidal tracts. As already mentioned, these tracts function to carry motor impulses from the cerebral cortex to the spinal cord. • The corticospinal tract originates in the motor cortex, which is located in the precentral gyrus of the brain’s cerebral cortex. Depending on where the neurons originate within the gyrus, they will supply different regions of the body. The corticobulbar (a.k.a. corticonulcear) tract is responsible for influencing the motor nuclei of a number of cranial nerves. • To master this topic, click on the link and carry on watching the full video (available to Premium members): https://khub.me/0aylt ! • Want to test your knowledge on the anatomy of the pyramidal tracts?
