Nervous Tissue

note: two large blue objects are neurons

Cell body with nucleus
Small extensions are dendrites
Usually one large extension is the axon (not really possible to say which that is in this image)
Lots of small nuclei visible in the background are neuroglia cells, which have a supportive function.

Conduction of electrical impulses from sensory receptors, and to effectors.

Central and peripheral nervous system
