Which of the following is not a part of areolar tissue ?
Areolar tissue is loose, irregularly arranged connective tissue. It consists of collagen, elastin and reticular fibres. It is strong enough to bind different tissue types together, and yet soft enough to provide flexibility and cushioning.
Macrophages, plasma cells and collagen fibres are all components of areolar tissues whereas, a nerve cell is not.
So, the correct option is B.
