Messages are carried from the eyes to the brain by?
The optic nerve and optic tracts.
What impulses do ascending tracts within the spinal cord carry to the brain?
reflex
What does the white matter in the brain do?
No, the white matter in brain tissue is the area of brain tissue that contains the nerve fibre tracts with their covering of myelin which appears white.
What are the different sides of the brain used for?
This has to do with neurological tracts that comes from the brain halves to the spinal cord. Tracts that come from the right brain cross over to the left side to the spinal cord, which controls nerve input and output from the environment on the left side. The same results occurs on the right side of the body from the left side of brain.
What region of the brain has gross crossover of fibers of descending pyramidal tracts?
延髓 (Medulla)
What role do spinal tracts play in the peripheral nervous system?
Spinal tracts are communication pathways. There are numerous tracts and they carry messages from 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 tracts of the spinal cord carry impulses away from the brain?
synape
What tracts of the spinal cord carry sensory information to the brain?
spinothalamic
What tracts the spinal cord carry sensory information to the brain?
spinothalamic
Messages are carried from the eyes to the brain by?
The optic nerve and optic tracts.
What impulses do ascending tracts within the spinal cord carry to the brain?
reflex
Most sensory tracts pass through this structure in the brain?
The arterial cortex.
Do descending fiber tracts of the spinal cord carry sensory or motor information?
The ascending tracts carry information to the brain.
What does the white matter in the brain do?
No, the white matter in brain tissue is the area of brain tissue that contains the nerve fibre tracts with their covering of myelin which appears white.

Communication between the brain and spinal cord involves tracts that ascend or descend through what?
Medulla!!
