Dense, Irregular Connective Tissue

In this connective tissue collagenous fibers predominate.

#4 Skin, H&E

Under the stratified squamous epithelium examined earlier is the dense irregular connective tissue of the dermis. Its thick collagenous (type I) bundles stain intensely with eosin and can be seen to course in various directions.

#70 Breast, Inactive (H&E)

Find the regions that contain ductal tissue at low power. Immediately surrounding these cells is a very small zone of pale-staining loose areolar connective tissue. Outside of this, there is a large zone of acidophilic dense irregularly arranged connective tissue. Clumps of white adipose tissue are scattered throughout the stroma of the mammary gland.
