Document Summary

Neural tube continuous between spine and brain, in mature structure - brain stem transition zone. Cerebellum regulates coordination develops from outfolding of neural tube. Brainstem highlighted yellow roots / origins of cranial nerves coming out of brain stems. First section moving from spinal cord into brain stem. Transmits ascending and descending impulses between the brain and spinal cord. Sending info in both directions bridge with spinal cord. Pyramids (two ridged areas / bumps) collections of white matter within it located anteriorly, collections of myelinated axons within brain - nerve tracts (bundle of axons in nervous system) Conscious control of skeletal muscle only contain axons for descending info, only motor axons not sensory axons. Collections of axons outside the brain or spinal cord is called a nerve , bundle or collection inside spinal cord its referred to as a tract myelinated or unmyelinated.
