• CNS
• motor
• sensory

part of nervous system under involuntary control

• somatic
• autonomic
• motor
• sensory

transport system for the neuron, ribosomes attach here

• integrative
• motor
• autonomic
• chromatophilic substance

provide insulating layers of myelin in the brain and spinal cord

• schwann cells
• oligodendrocytes
• astrocytes
• ependymal cells

myelinated axons

• white matter
• gray matter
• neurofibrils
• neurilemma

rounded area of a neuron

• axon
• synapse
• cell body
• dendrite

portion of the CNS that decodes signals sent by the sensory portion

• motor
• sensory
• integrative
• brain

cells that form the myelin sheath around the axons

• astrocytes
• oligodendrocytes
• Schwann cells
• neuroglial

portion of the nervous system that gathers info from the environment

• motor
• integrative
• sensory
• autonomic

cells that fill the spaces in the nervous tissue

• neuroglial
• microglial
