In this lesson, we will discuss the spinal cord's key components, including the gray matter and white matter, fecal sac, conus medullaris, filum terminale, cauda equina, denticulate ligaments, and spinal nerves. Let's get started. Like the brain, the spinal cord is composed of gray and white matter. In the brain, the gray matter is located more toward the outside, and the white matter is located more toward the interior. For the spinal cord, this is reversed. The gray matter is located more centrally, and the white matter is located peripherally. First, let's look inside at the gray matter.

Surrounding the gray matter is the white matter. It is made
