What are Large bundles of axons and dendrites make up called?
Large bundles of axons and dendrites are called nerves or tracts depending on their location in the central or peripheral nervous system.
Is our spinal cord made of bundles of neurons that carry impulses from all parts of the body to the brain and from the brain to all the parts of your body?
Well not neurons, there are nerves in the spine. Neurons exist in the brain. With that being said, yes the spine is made of nerves that carry electrical impulses from every region of the body to the brain and from the brain to the body.
Why do messages not get mixed up passing through the spinal cord?
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.
What is the term for axon pathways carrying information up and down the spinal cord?
The term for axon pathways carrying information up and down the spinal cord is "spinal tracts." These tracts are responsible for transmitting sensory information to the brain and motor commands from the brain to the body. They are classified into ascending tracts, which carry sensory information, and descending tracts, which convey motor information.
