Peripheral Nervous System= Oligodendrites
Central Nervous System= Schwaan Cells
Oligodendrites myelinate 250 times faster than Schwaan cells
The specialized cells that myelinate the fibers of neurons in the peripheral nervous system are called Schwann cells. Schwann cells wrap around the axons of neurons to form the myelin sheath, which helps to insulate and protect the nerve fibers, allowing for faster and more efficient conduction of nerve impulses.
schwann cells
1) starting with the obvious; oligodendrocytes myelinate axons in the CNS whereas schwann cells myelinate axons in the PNS 2) a single oligodendrocyte is able to myelinate multiple axons whereas a schwann cell can only myelinate a single axon. 3) schwann cell myelination allows for axonal grown and regeneration where as oligodendrocytes inhibit axonal growth and regeneration. 4).... and probably a bunch more differences
Neurons are specialized cells that transmit electrical and chemical signals in the body. They have long, slender extensions called dendrites and axons that allow them to communicate with other neurons. Dendrites receive incoming signals, while axons transmit signals to other neurons or cells.

Oligodendrocytes are a type of glial cell in the central nervous system that primarily function to support and insulate axons by forming myelin sheaths. These myelin sheaths enhance the speed of electrical signal transmission along nerve fibers, facilitating efficient communication between neurons. Oligodendrocytes can myelinate multiple axons, contrasting with Schwann cells in the peripheral nervous system, which typically myelinate only one axon. Additionally, they play a role in maintaining the health and metabolic support of neurons.
Oligodendrocytes are glial cells that function in the CNS--the brain and spine. They provide insulation (myelin sheaths) in several locations, possibly multiple neurons. Meanwhile, schwann cells are glial cells that function in the PNS--peripheral nervous system, everything outside the brain and spine. Individually, they wrap around axons of nerves, forming individual segments of myelin sheaths. They, unlike oligodendrocytes, can guide repairs to damaged axons. Damage to the nerves in the brain are not so easily remedied.
Nerve tissue is supported by specialized cells known as glial cells or neuroglia. These cells provide structural support, insulation, and protection for the neurons in the nervous system. They also play a role in regulating the extracellular environment of neurons.
Neurons are the conducting cells of nerve tissue. The neurons transmit the electrical charges and chemical signals via the synapses.
Granule cells are the only excitatory neurons in the cerebellar cortex. They receive input from mossy fibers and synapse onto Purkinje cells and Golgi cells.
GLIAL
Animal cells specialized for conducting electrochemical impulses are known as neurons. Neurons have unique structures such as dendrites, axons, and synapses that allow for the transmission of electrical signals within the nervous system.
