Types of Neurons & Neuroglia

Types of Neurons

MBU

• Multipolar

• Bipolar

• Unipolar

 Several dendrites and one axon

Multipolar

Most neurons and most CNS neurons

Multipolar

One dendrite and one axon

Bipolar

Found in special organs such as the eye and the nose

Bipolar

A neuron with a single axon

Unipolar

Most sensory neurons

Unipolar

Types of Neuroglial Cells

• AEMOS

• Astrocyte

• Ependymal 

• Microglia

• Oligodendrocytes

• Schwann cells

Star-shaped

Astrocyte

Structural support of the CNS; contributes to the formation of blood-brain barrier

Astrocyte

Squamous epithelial-like

Ependymal

line the CSF-filled ventricles in the brain & the central canal of spinal cord

Ependymal

Small mobile cells

Microglia

Phagocytic that protects the CNS from infection

Microglia

With processes

Oligodendrocytes

Provide support & insulation to axons in the CNS.

Oligodendrocytes

Myelinate axons in the CNS

Oligodendrocytes

Single cell

Schwann cells

Myelinate axons in the PNS

Schwann cells
