What else can I help you with?
The myelin sheath that covers many CNS axons is formed by?
Oligodendrocytes
What are the four types of glial cells?
astrocytes, microglia, ependymal, and oligodendrocytes.
Which neuroglial cell is responsible for the production of myelin sheaths around axons in the central nervous system?
Oligodendrocyte; processes of the oligodendrocytes form the myelin sheaths around the CNS nerve fibers
Are oligodendrocytes unipolar bipolar or multipolar?
Oligodendrocytes are unipolar.Source: "Human Anatomy & Physiology" by Elaine N. Marieb and Katja Hoehn, ninth edition
What type of neuroglia forms the myelin sheath?
oligodendrocytes for C.N.S. and shcwann cells for P.N.S.
Schwann cells are functionally similar to what?
oligodendrocytes
Which cells form myelin in the spinal cord?
They are called oligodendrocytes but in the peripheral nervous system you would call them schwann cells.
Which does not belong astrocytes neurons oligodendrocytes or microglia?
neurons
What produce myelin in the brain and spinal cord?
Oligodendrocytes produce myelin in the brain and spinal cord. This process is known as myelination and the myelin will warp itself around the neurons.
How are oligodendrocytes precursor cells identified?
Oligodendrocytes precursor cells are identified by them expressing a number of antigens. The develop during embryo-genesis and during the early stages of postnatal life.
Function of oligodendrocytes?
Form myelin in the brain and spinal cord....
What are the four types of neuroglia in the CNS?
The four types of neuroglia in the central nervous system (CNS) are astrocytes, oligodendrocytes, microglia, and ependymal cells. Astrocytes provide structural support and regulate the chemical environment, oligodendrocytes produce myelin to insulate axons, microglia are the immune cells of the CNS, and ependymal cells line the ventricles and produce cerebrospinal fluid.
