White matter is composed of
A) ganglial sheaths.
B) bundles of myelinated axons.
C) collections of nerve cell bodies.
D) bundles containing both myelinated axons and nerve cell bodies.
E) collections of unmyelinated axons.
White Matter
A component of the central nervous system, primarily consisting of myelinated nerve fibers and responsible for communication between different brain regions.
Myelinated Axons
Axons that are encased in myelin, a fatty substance that speeds up the transmission of nerve impulses.
Ganglial Sheaths
Protective coverings around ganglia, which are clusters of nerve cell bodies in the peripheral nervous system.
