By K Balaji|Updated : January 20th, 2023

The Spinal Cord originates from the Medulla Oblongata. It is located at the base of the brain in its bottom part. The medulla is the part which connects the spinal cord with our brain. The spinal cord ends in the lower back. It is a thin, long, tubular structure made up of nervous tissue. The spinal cord and brain together make the central nervous system.

Where does Spinal Cord Originate from?

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.

More details on Spinal Cord

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.


The Spinal Cord Originates from ________

The origin of the spinal cord is the medulla oblongata and it ends in the lower back. The medulla acts as the connector of the brain and spinal cord. It is also a channel responsible for the to and fro motion of nerves in our body. Medulla oblongata also controls various important functions in our body, such as breathing, heartbeat, and motor skills and instructions like walking.
