Spinal Cord: In a Nutshell (Nursing)

00:01 Okay, so let's wrap up this introduction to the spinal cord.

00:04 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.

00:11 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.

00:20 The spinal cord is an information bridge or information highway between the brain and the other body organs.

00:28 It provides sensory information and motor function to the rest of the body.

00:33 The vertebral column consists of 33 bones stacked up on top of each other and they have discs in between that help facilitate movement.

00:42 The bones, meninges, layer of fat, veins and CSF are what protect the spinal cord.

00:49 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.

01:00 A layer of fat, veins and cerebrospinal fluid.

01:04 Now, the spinal cord contains both white and gray mater.

01:09 Make sure you go over and review for yourself what makes white matter white and what makes gray matter gray.

01:16 Thank you for watching our intro video today.
