Dense irregular connective tissue
Dense irregular connective tissue has fibers that are not arranged in parallel bundles as in dense regular connective tissue.
Substances formed
This tissue comprises a large portion of the dermis.[1] This type of tissue is also in the protective white layer of the eyeball and in the deeper skin layers.
It also makes up submucosa, fibrous capsules, and some types of fascia.[2] Other examples include periosteum and perichondrium.
Dense irregular tissues have fibroblasts and matrix fibers (mostly collagen) that are oriented differently, e.g. not oriented in a parallel fashion. This tissue is present in the skin.
Composition
It consists primarily of collagenous fibers.[3]
