Okay, so let's wrap up this introduction to the spinal cord.
Now, you've learned a lot about the spinal cord but we have so much more to get into
but let's go back on a quick review.
The brain and spinal cord are connected by the brain stem,
so, in between the brain and the spinal cord we have our three friends in the brain stem.
The spinal cord is an information bridge or information highway between the brain and the other body organs.
It provides sensory information and motor function to the rest of the body.
The vertebral column consists of 33 bones stacked up on top of each other
and they have discs in between that help facilitate movement.
The bones, meninges, layer of fat, veins and CSF are what protect the spinal cord.
Okay, don't miss that. So what protects the spinal cord or the bones?
The meninges, those are those layers, right? PAD, pia, arachnoid, and dura.
A layer of fat, veins and cerebrospinal fluid.
Now, the spinal cord contains both white and gray mater.
Make sure you go over and review for yourself what makes white mater white and what makes gray mater gray.
Thank you for watching our intro video today.
