III.reticular connective tissuea.description:fine interlacing network of reticularfibers (thin form of collagen fiber) and reticularcells.b.location:stroma (supporting network) of liver,spleen, lymph nodes; red bone marrow; reticularlamina of basement membrane; around bloodvessels and muscles.c.function:forms stroma of organs; binds smoothmuscles tissue cells; filter and removes worn-outblood cells in spleen and microbes in lymph nodes.B.dense connective tissue– contains more fibers, which arethicker and more densely packed, but have considerably fewercells than loose connective tissue.I.dense regular connective tissuea.description:forms shiny white extracellularmatrix; mainly collagen fibers regularly arranged inbundles with fibroblasts in rows between them.Collagen fibers are not living, so damaged tendonsand ligaments heal slowly.b.location:forms tendons (attach muscle to bone),most ligaments (attach bone to bone) andaponeuroses (sheet-like tendons that attachmuscle to muscle or muscle to bone)c.function:provides strong attachment betweenvarious structures. Tissue structure withstandspulling (tension) along long axis of fibers.

II.dense irregular connective tissuea.description:made of collagen fibers; usuallyirregularly arranged with a few fibroblasts.b.location:often occurs in sheets, such as fasciae(tissue beneath skin and around muscles and otherorgans), reticular (deeper) region of dermis of skin,fibrous pericardium of heart, periosteum of bone,perichondrium of cartilage, joint capsules,membrane capsules around various organs(kidneys, liver, testes, lymph nodes); also in heartvalves.c.function:provides tensile (pulling) strength inmany directions.III.elastic connective tissuea.description:contains predominantly elastic fiberswith fibroblasts between them; unstained tissue isyellowishb.location:lung tissue, walls of elastic arteries,trachea, bronchial tubes, true vocal chords,supersensory ligaments of penis, some ligamentsbetween vertebrae.c.function:allows stretching of various organ; isstrong and can recoil to original shape after beingstretch. Elasticity is important to normalfunctioning of lung tissue (recoils in exhaling) andelastic arteries (recoil between heartbeats to helpmaintain blood flow)C.cartilage – consists of dense network of collagen fibers andelastic fibers firmly embedded in chondroitin sulfate, a gel-likecomponent of the ground substance; can endure considerablymore stress than loose and dense connective tissues; strengthis due to collagen fibers while resilience is due to chondroitinsulfate. Cartilage has no blood supply; it heals poorly followingan injury.
