Cells of the Nervous System

Biology ll

Attach neurons to blood capillaries

Astrocytes

Don’t divide, so they cannot be replaced

Neuron

Form the myelin sheath in the central nervous system

Oligodendrocytes

Form the myelin sheath in the peripheral nervous system

Schwann cells

Have a long lifespan (can live your entire life)

Neuron

Largest type of neurological cell

Astrocyte

Main cells of the nervous system

Neuron

Most numerous type of neurological cell

Astrocyte

Neurological cells of the CNS

Astrocytes, Ependymal cells, Microglial cells, and Oligodendrocytes

Neurological cells of the PNS

Schwann cells and Satellite cells

Phagocytose bacteria and debris around injured neurons

Microglial cells

Regulate levels of oxygen, CO2, and nutrients around the neuron

Satellite cells

Require constant oxygen and die quickly without it

Neuron

Send impulses from one part of the body to another

Neuron

Sense and approach injured neurons

Microglial cells

Surround the cell body of a neuron

Satellite cells

Type of neuroglial cell

Astrocyte, Ependymal cells, Microglial cells, Oligodendrocytes, Schwann cells, and Satellite cells

Use cilia to circulate cerebrospinal fluid around the brain

Ependymal cells

Use cilia to circulate cerebrospinal fluid around the spinal cord

Ependymal cells
