Usually they are simply called nerves. Depending on the scenario, sometimes they are called nerve tracts or pathways.
Spinal Cord.
The thick bundle of nerve fibers through which the brain communicates with the body is the spinal cord.
The spinal cord is made up of bundles of nerve fibers. It runs down from the brain through a canal in the center of the bones of the spine. These bones protect the spinal cord. Like the brain, the spinal cord is covered by the meninges and cushioned by cerebrospinal fluid.
I do not know find out on your own use you brain!
Interneurons send messages from the spinal cord to the brain.
There are ascending and descending tracts in the spinal cord. These tracts are nerve fibers bundled together. Messages going to the brain pass through the ascending tracts while messages coming from the brain pass through the descending tracts. These separate paths prevent messages from getting mixed up.
The longitudinal bundles of nerve fibers within the spinal cord that comprise major nerve pathways are called tracts. These tracts are organized based on their function and transmit information to and from different regions of the body to the brain.
Messages from the femoral nerve are sent to the brain through a series of electrical impulses. These impulses travel along the nerve fibers of the femoral nerve until they reach the spinal cord, where they are then transmitted up to the brain via the spinal cord's sensory pathways. Once in the brain, the messages are interpreted and processed to produce a response or sensation.
i think the brain sends messages between different parts of the body.
Spinal cord
Your brain stem.
yes spinal cord attached to the brain .spinal cord have bundles of nerves which attached to the brain.
