What is the function of oligodendrocytes cells?
Oligodendrocytes are the myelinating glia of the central nervous system. Myelination of axons allows rapid saltatory conduction of nerve impulses and contributes to axonal integrity.
What is the function of oligodendrocytes and Schwann cells?
Oligodendrocytes and Schwann cells are engaged in myelin production, maintenance and repairing respectively in the central nervous system (CNS) and the peripheral nervous system (PNS).
What is the function of oligodendrocytes quizlet?
Schwann cells wrap their entire cell bodies around an axon to form only one myelin sheath and are in the PNS. Oligodendrocytes ” arms ” wrap around multiple axons to form myelin and are in the CNS. Both cells provide support.
How do oligodendrocytes support neurons?
Apart from their myelinating function, oligodendrocytes also provide trophic support to neuronal cells by releasing lactate. This release is mediated by the monocarboxylate transporter-1 (MCT1) [63].
What would happen if oligodendrocytes are destroyed?
Thus, neurotransmitter receptors play an important role in the normal life of oligodendrocytes. Furthermore, if oligodendrocytes become damaged and the myelin sheath is destroyed, the action potential is reduced in velocity or ceases altogether, leading to physical or mental disability.
Where do oligodendrocytes come from?
The oligodendrocytes derive from oligodendrocyte precursor cells (OPCs), which arise from multiple restricted regions of the ventricular zone in the developing CNS, including the telencephalon, diencephalon, mesencephalon, rhombencephalon and spinal cord.
What happens if oligodendrocytes are damaged?
Furthermore, if oligodendrocytes become damaged and the myelin sheath is destroyed, the action potential is reduced in velocity or ceases altogether, leading to physical or mental disability.
