Lack of blood supply and presence of the noncellular basement membrane are the characteristics of the
muscular tissue
fluid connective tissue
epithelial tissue
nervous tissue
Correct Answer :
C. epithelial tissue
Epithelial tissue covers the body surface, or lines the body cavity. The cells rest upon a non-cellular basement membrane which is secreted by epithelial cells. It is not nourished by blood, so non-vascularized.
