Neuroglia also known as glial cells which act as supporting cells for the nervous system and its functioning. These cells surrounds the neurons and produce insulation between them as they produce myelin sheath that coats the axon. There are six types of neuroglia cells and they all work to provide essential nutrients to the neuron cell and also maintain the homeostasis (under which it also regulate the interstitial fluid composition and repair tissue framework)
Neuroglia refers to the Glial cells present in the nervous system of animals which serves many functions in the system. These cells are present in both the types of nervous systems that are in the central and peripheral.
The glial cells during evolution were formed not to conduct the impulses but to support the neurons. This support is provided in the term of the physical, mechanical support and protection. The glial cells surround the axons and form the myelin sheath and at the same time, some different cells become immune cells to protect the neurons. Some cells stabilize the balance in the neurons.
Hmm, let me see. This illustration appears to be an image of a cell. But, there aren't any answers that has cell. Using logic, it would be an organelle. Mainly because there aren't any arrows directing to a specific organelle. Since a cell wall is an organelle, it has to be D.
