simple squamous
Epithelial: lines airsacs of lungs & capillaries
Single thin layer allows for easy diffusion of substance
simple cuboidal
Epithelial: lines renal tubules in kidney, surface of ovaries and forms many glands
Secretes substances
simple columnar
Epithelial: lines digestive system; characteristic Goblet cells secrete mucus, also absorbs and creates protective barrier against bacteria in gut
stratified squamous
Function: protects underlying tissues in areas subject to abrasion
Location: nonkeratinized type forms the moist lining of the esophagus, mouth, and vagina; keratinized type forms the epidermis of the skin, a dry membrane.
transitional
Epithelial: numerous layers of cells with varying shape; able to be stretched
Found in bladder and urinary tract
pseudostratified columnar
Epithelial: ciliated version lines respiratory system; secretes mucus with Goblet cells; cilia moves mucus into oral cavity
bone
Connective: hard calcified matrix, many collagen fibers
Support, protection and mineral storage
hyaline cartilage
Connective: collagen fibers, rubbery matrix made by chondroblasts; serves as cushioning and resists pressure
Found in costal cartilage of the ribs, nose, trachea and fetal skeleton
elastic cartilage
Connective: more elastic fibers than hyaline and allows for flexibility
Found in epiglottis, outer ear, and trachea
areolar
Connective proper loose: (also called loose connective)characteristic Fibroblast cells, all three fibers visible in matrix(collagen, elastin & reticular).
Found in almost every part of the body. It surrounds blood vessels and nerves and penetrates with them into the small spaces of muscles, tendons, and other tissues.
Binds and provides cushioning
dense fibrous
Connective proper dense: Characteristic some Fibroblast cells with dense collagen matrix
Regular: parallel collagen fibers; found in tendons & ligaments; strong and attaches muscle to bone or bone to bone.
Irregular: found in dermis of skin and capsules of joints; withstands tension from different directions
blood
Connective: matrix is mostly water, fibers only present during clotting, characteristic cells erythrocytes, some leukocytes; delivers oxygen, nutrients, and hormones, carries waste
adipose
Connective proper loose: minimal matrix, characteristic fat cells, stores fat droplet inside cell, nucleus pushed to side.
Found deep to skin and surrounding many organs as well as the breasts.
reticular
Connective proper loose: Characteristic fibroblast cells also contains many white blood cells(leukocytes) surrounded by delicate fibers
Acts as supporting network around the liver, the kidney, the spleen, and lymph nodes. Also found in bone marrow.
skeletal
Muscle: striations, many peripheral nuclei
Found attached to bones
moves skeleton
smooth
Muscle: no striations, tapered cell, one center nucleus
Found in most hollow organs/blood vessels
moves substances through organs
cardiac
Muscle: characteristic intercalated discs, branching cells, one center nucleus
Found in heart, moves blood through vessels
neuron
Nervous: characteristic neuron (nerve cell),
sends messages can be found in the peripheral nervous system
fibrocartilage
Connective: less firm than hyaline with thick collagen fibers; absorb compressive shock
Found in pubic symphysis(between pelvic bones) and intervertebral discs
dense elastic
Connective proper dense: high proportion of elastic fibers; functions to recoil after stretching whether non-passive or passive like in the lungs
Found in large arteries like the aorta
