The Dura, Arachnoid, and the Pia Mater (the meninges)
No, the medulla refers to the lower part of the brainstem responsible for vital autonomic functions like breathing and heart rate regulation. The backbone, also known as the spine or spinal column, is a bony structure that houses and protects the spinal cord.
The spinal cord.
The spinal cord is the part of the nervous system that extends down the back. It is a long, thin, tubular bundle of nervous tissue and serves as the main pathway for transmitting messages between the brain and the rest of the body.
All animals with a spinal chord have a spinal column to protect it. The spinal column is often referred to as the "back bone", so only vertebrates have one.
The Vertebral Column (aka, the spine or backbone) protects the spinal cord and supports the head and back.
In order to protect the spinal cord.
The spinal cord is a structure that starts at the brain and extends down the back within the spinal column. It serves as a pathway for nerve signals traveling between the brain and the rest of the body, controlling movement, sensation, and other functions.
The spinal column is a series small bones that helps support the body and surrounds the spinal cord which has nerve links from the cord to various parts of the body and leading back to the brain.
The spinal cord is part of the central nervous system that extends from the brainstem to the lower back and can be considered outside the cranium. It is housed within the spinal canal of the vertebral column.
The spinal cord is a long, thin, tubular bundle of nerves that is an extension of the central nervous system from the brain and is enclosed in and protected by the bony vertebral column (aka. the back bones). The main function of the spinal cord is transmission of neural inputs between the periphery (legs, arms, torso, etc) and the brain. In summary, the term spinal cord is correct medical/anatomical language. There is no better way of naming this structure of the body. I think all the person asked for is it's medical name and that is "myel-"
The spinal column is a bony encasement made of movable discs, which protect the spinal cord but allow for movement. If the spine is bent too sharply the spinal column or spinal cord can be injured. http://www.brainandspinalcord.org/spinal-cord-injuries/index.html
