What else can I help you with?
What type of neuroglia forms the myelin sheath?
oligodendrocytes for C.N.S. and shcwann cells for P.N.S.
Myelin is a lipid insulation produced by the?
Myelin is a lipid insulation produced by the cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. It wraps around nerve fibers to help speed up the transmission of electrical impulses along the nerve cells.
What two cells form the insulating sheaths around axons?
Schwann cells and oligodendrocytes
What type of cells produce the myelin sheath in the central nervous system?
Oligodendrocytes and Schwann cells both produce myelin. Oligodendrocytes produce myelin in the CNS, whereas Schwann cells produce myelin in the PNS. CNS refers to central nervous system PNS refers to peripheral nervous system
What is a precursor of basophil monoblast lymphoblast megakaryoblast or myeloblast?
The precursor of basophils is the basophil progenitor cell, the precursor of monoblasts is the monoblast cell, the precursor of lymphoblasts is the lymphoblast cell, the precursor of megakaryoblasts is the megakaryoblast cell, and the precursor of myeloblasts is the myeloblast cell. These precursor cells undergo differentiation and maturation processes to become fully functional mature blood cells.
What are the four types of glial cells?
astrocytes, microglia, ependymal, and oligodendrocytes.
What are the origin of astrocytes and oligodendroglia?
Astrocytes and oligodendrocytes originate from neuroepithelial cells in the developing nervous system. Astrocytes arise from radial glial cells, which serve as neural stem cells, while oligodendrocytes are derived from oligodendrocyte precursor cells (OPCs) that migrate from the germinal zones. Both cell types play important roles in supporting and protecting neurons in the brain and spinal cord.
Which cells form myelin in the spinal cord?
They are called oligodendrocytes but in the peripheral nervous system you would call them schwann cells.
Schwann cells are functionally similar to what?
oligodendrocytes
Which type of glial cells produces the myelin sheaths that insulate axons or nerve fibers in the central nervous system (CNS)?
myelin sheath
What type of neuroglia forms the myelin sheath?
oligodendrocytes for C.N.S. and shcwann cells for P.N.S.
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.
Myelin is a lipid insulation produced by the?
Myelin is a lipid insulation produced by the cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. It wraps around nerve fibers to help speed up the transmission of electrical impulses along the nerve cells.
What two cells form the insulating sheaths around axons?
Schwann cells and oligodendrocytes
Schwann cells are functionally similar to?
Schwann cells are functionally similar to oligodendrocytes in the central nervous system. They both provide support and insulation to nerve fibers by forming a myelin sheath around them, which helps in the transmission of nerve signals. Schwann cells are found in the peripheral nervous system while oligodendrocytes are found in the central nervous system.
What type of cells produce the myelin sheath in the central nervous system?
Oligodendrocytes and Schwann cells both produce myelin. Oligodendrocytes produce myelin in the CNS, whereas Schwann cells produce myelin in the PNS. CNS refers to central nervous system PNS refers to peripheral nervous system
Four types of neuroglia in the cns?
The four types in the CNS are microglia, astrocytes, ependymal, and oligodendrocytes. *microglia= phagocytes *astrocytes= form the blood brain barrier *ependymal= produce CSF (cerebral spinal fluid) *oligodendrocytes= form the myelin sheath that wraps around the axon
