Neurons form intricate circuits that 1 relay sensory information from the internal and external environments 2 integrate information among millions of neurons and 3 transmit effector signals to muscles and glands. Anatomical subdivisions of nervous tissue Central nervous system CNS Brain Spinal cord Peripheral nervous system PNS Nerves Ganglia singular ganglion CELLS OF NERVOUS Tissue Neurons Functional units of the nervous system receive process store and transmit information to and from other neurons muscle cells or glands Digital Histology An Interactive CD Atlas with Review Text by Alice S.
