Types of Neurons

Sensory neurons

-carry impulses from the peripheral parts of the body to the CNS.

Interneurons

-located entirely within the CNS and synapse with other neurons.

-responsible for the processing and interpretation of impulses by the CNS.

Motor neurons

-carry impulses from the CNS to effectors, to produce an action.

-cell bodies and dendrites are located within the CNS.

-aXons are located in cranial and spinal nerves.

Schwann Cells

- occur only in the peripheral nervous system.

-they form the myelin sheath around axons.

micoglial cells

-are scattered throughout CNS.

-keep the tissues clean by englufing and digesting cellular debris and bacteria.

oligodendrocyte cell

-type of neuroglial cell that supports nerurons and forms myelin around some nerve fibers within the CNS.

astrocyte cell

-primary supporting cells for nuerons in the brain.

-stimulate growth of neurons

-influence synaptic transmission

ependymal cell

form an epithelial-like lining of cavities in the brain and spinal cord.
