393-Neurons associate closely with much smaller cells called -----

• Neuroglia

• Glial Cells

• CNS

• PNS

Shaped like delicate branching sea anemones, ----- are the most abundant and versatile glial cells. 393

• Astrocytes

• Microglial Cells

• Ependymal Cells

• oligodendrocytes

------are small and ovoid with relatively long “thorny” processes-393

• Astrocytes

• Microglial Cells

• Ependymal Cells

• oligodendrocytes

-- range in shape from squamous to columnar, and many are ciliated--393

• Ependymal Cells

• oligodendrocytes

-- Though they also branch, the ----- have fewer processes than astrocytes--393

• Astrocytes

• Microglial Cells

• Ependymal Cells

• oligodendrocytes

cells surround neuron cell bodies located in the peripheral nervous system-394

• Satellite

• Schwann

• Somatic

• Autonomic

(also called neurolemmocytes) surround all nerve fibers in the PNS and form myelin sheaths around the thicker nerve fibers-394

• Schwann cells

• satellite cells

• ACH

• Dendrites

The ---- is the major biosynthetic center and metabolic center of a neuron-394

• CNS

• PNS

• Cell body

• axons

---

of motor neurons are short, tapering, diffusely branching extensions.-395

• Dendrites

• Axons

• Rods

• cones

A neuron never has more than a single -----395

• Axon

• Dendrite

• OCH

• Sensory nerve
