collagenous fibers
|
|| fibrils, of collagen, in all types of CT especially bones cartilage tendons and ligaments
|
|
|
reticular fibers
|
thin and branching, collagen with glycoprotein coat, form a network around fat cells nerve cells muscle fibers and blood vessels, forms stroma(framework) for soft organs such as spleen
|
|
|
elastic fibers

|
many kinds of cells, much intercellular matrix, highly vascular, except for cartilage, never exposed to outside of body
|
|
|
mesenchyme
|
tissue from which all others CT's eventually arise, stem cells
|
|

|
|
Mature CT or CT proper
|
newborn to adult, does not change after birth
|
|
|
areolar or loose CT
|
cells ie fibroblasts produce fibers,ground substance, fibers
|
|
|
adipose tissue
|
cells are adipocytes specialized for fat storage, fat or lipid is a cell inclusion. Signet class ring little ground substance or fiber, two types
|
|
|
signet class rings
|
formed when the cytoplasm and the nucleus are pushed to the periphery of the cell
|
|
|
white fat
|
used for insulation

|
reticular cells, reticular fibers are interlacing, forms stroma of spleen, liver and lymph nodes
|
|
|
dense CT

fibroblasts in rows between bundles of collagenous fibers in parallel arrangement, very strong, makes up most of tendons, aponeuroses, ligaments
|
|
|
dense irregular CT
|
fibers without regular orientation, located where tensions are exerted in a number of directions, forms reticular region of dermis, periosteum, perichondrium, membrane capsules, encloses cavities of joints
|
|
