Mesoscopic - Answer-groups of cells linked together in various systems (vestibular
system)

Macroscopic - Answer-the whole human interacting in their environment (child swinging)

Distributed control - Answer-at any one time, the nervous system coordinates many
different activities (taking notes in the classroom)

Adaptation - Answer-the human nervous system is able to change which can lead to

some specific function (lang on left for most people)

Phylogenetic layers - Answer-most newer parts of our brain are located at the top of our
head and the more primitive parts located deeper and lower

dendrite, cell body, & axon

cell - Answer-cell body

nerve fibers - Answer-dendrites and axons

white matter - Answer-tissue of the CNS rich with myelinated axons

fissure - Answer-a deep sulcus

cortex - Answer-outer layer of an organ or body structure

Nucleus (nuclei) - Answer-group(s) of functionally or structurally related cell bodies in
the CNS

Ganglion (ganglia) - Answer-group(s) of functionally or structurally related cell bodies in
the PNS

the CNS

Layer, lamina (laminae), stratum (strata) - Answer-group(s) of functionally related cells
that form a layer
