4 Questions
What is the function of oligodendrocytes in the CNS?
Provide the myelin sheath around the axons of neurons, increasing axonal conduction.
How many glia cells are there for every three neurons in our brains?
Roughly two
What is the function of interneurons?
They perform a similar function to oligodendrocytes but in the PNS.
What characterizes a multipolar neuron?
A neuron with many processes extending from its cell body.
Study Notes
Glial Cells
- Oligodendrocytes are responsible for myelinating axons in the Central Nervous System (CNS)
Glial Cell Ratio
- For every three neurons in our brains, there are approximately one glial cell
Interneurons
- Interneurons are responsible for regulating the activity of other neurons, acting as intermediaries in neural circuits
Multipolar Neurons
- Multipolar neurons are characterized by having multiple dendrites that arise from the cell body
Test your knowledge about the glia cells and different types of neurons in the central nervous system. This quiz covers the functions of glia cells, their role in providing the myelin sheath, and the characteristics of multipolar, bipolar, and unipolar neurons.
