Corpo - O sistema nervoso

the body part that is inside our head controlling how we feel, think, move, etc.

cérebro da pessoa

a cell that is responsible for transmitting nerve impulses between the brain and the rest of the body

(anatomy) a network of nerves in the abdomen and in front of the aorta that contains several ganglia

plexo solar

(anatomy) a mass of neurons that form a nerve center in the body outside the brain or spinal cord

gânglio

related to or associated with glia or glial cells in the nervous system

glial

a complex arrangement or network of nerve fibers or blood vessels that intersect and intertwine within the body
