The spinal cord originates from which part of the body?

The spinal cord starts from the Medulla Oblongata, which is located at the bottom part of the brain. The diameter of the spinal cord ranges from 6.4 mm to 13 mm. It plays a main role in the transmission of nerve signals in the human body.

It is a point for coordinating many reflexes and contains reflex arcs. The nerves associated with the spinal cord are responsible for controlling the motor instructions such as walking.

The key points related to the spinal cord have been provided below:

  • It is the main path for information connecting the brain and peripheral nervous system.
  • It is ovoid-shaped and enlarged in the cervical and lumbar regions.
  • Three layers of membrane called meninges surround the spinal cord to protect it.
  • The parts of the spinal cord are the central canal, posterior median sulcus, gray matter, white matter, dorsal root & dorsal root ganglion, ventral root, fascicles, anterior spinal artery, arachnoid mater, and dura mater.
