Which tissue type is primarily involved in meningiomas?

The correct response is based on the understanding of the origin and characteristics of meningiomas. Meningiomas are primarily tumors that arise from the meninges, the protective layers surrounding the brain and spinal cord. These layers are composed of arachnoid and dura mater, which are types of connective tissue. While the meningeal tissue can be classified under connective tissue, the primary context of meningiomas relates more to their association with the surrounding nervous system structures, as they primarily affect the central nervous system.

This close relationship with the nervous system is significant as meningiomas tend to exert pressure on the brain or spinal cord and can lead to neurological symptoms. Thus, the classification emphasizes that these tumors develop in the vicinity of nervous tissue, which is why the answer focuses on nervous tissue.
