TRUE

In places, the dermis may exhibit either smooth or skeletal muscle fibers.

TRUE

Which of the following tissues is found in the dermis of the skin?

DENSE IRREGULAR

flexion and extension

When bone is stressed on one side, it usually bends slightly on the other side and does not fracture. This is due to tensile strength caused by

collagenous fibers
