Which type of tissue is affected by fibromas?

Fibromas are tumors that develop from fibrous or connective tissue. This type of tumor is characterized by the proliferation of fibroblasts, which are cells that produce collagen and other fibers and play a crucial role in the structure and function of connective tissues. Since fibromas originate in fibrous tissue, the correct answer directly correlates with the tissue type that is affected.

The other types of tissues mentioned are not directly related to the origin of fibromas. Adipose tissue is primarily composed of fat cells and does not participate in the development of fibromas. Nervous tissue is made up of neurons and glial cells and is not involved in fibrous tissue tumors. Epithelial tissue includes layers of cells that cover surfaces or line cavities and is also not where fibromas develop. Thus, the specific nature of fibromas makes fibrous tissue the correct answer.
