Elastic
epithelium
makes up most of the body tissue
forms linings or coverings
highly cellular cells fit closely together
polarity (apical-free) surface and basal surface (basement) membrane
one flat layer- simple squamus
cubes- simple cuboidal
colum- simple columnar
2+ layers are stratified
-a vascular, no blood vessels, highly mitotic
connective tissue
connect things, no free surface
- binds supports and protects
- spread out
- contain matrix
matrix
fibrous, ground material that fills in spaces of connective tissue
simple squamous epithelium
simplest of the epithelia
function: allows materials to pass by diffusion and filtration where protection is not important. secretes lubricating substances
Location: kindey, air sacs of lungs, lining of heart, blood vessels and lymphatic vessels
simple cuboidal epithelium
single layer of cube like cells with large speherical central nuclei
function: secretion and absorption
location: kindey tubules, ducts and secretory portions of small glands; ovary surface
simple columnar epithelium
description: single layer of tall cells with round to oval nuclei; may contain goblet cells
function: absorption; secretion of mucus, enzymes and other substances; ciliated type propels mucus or reproductive cells
location: non cilated type lines most of the digestive tract (stomach and rectum) gall bladder and excretory ducts of some glands; ciliated variety lines small bronchi uterine tubes and some regions of the uterus
pseudostratified columnar epithelium
description- single layer of cells differing heights, some not reaching the free surface; nuclei seen at different levels; may contain goblet cells and cilia
function: secretes substances, particularly mucus; propulsion of mucus by ciliary action
location: nonciliated type in males sperm carrying ducts and ducts of large glands; ciliated variety lines the trachea, most of the upper respiratory tract
stratified squamous epithelium
description: thick membrane composed of several cell layers; basal cells are cuboidal or columnar and metabolically active; surface cells are flattened; basal cells are mitotic
function: protects underlying tissues in areas subjected to abrasion
locaiton: nonkeratinized type forms the moist lingings of the esophagus, mouth, and vagina; keratinized variety forms the epidermis of the skin a dry membrane
stratified cuboidal epithelium
description: generally 2 layers of cubelike cells
function: protection
location: largest ducts of sweat glands mammary glands and salivary glands
stratified columnar epithelium
description: several cell layers, basal cells usually cuboidal; superficial cells elongated and columnar
function: protection; secretion
location; rare in body; small amounts in the male urethra and in large ducts of some glands
transitional epithelium
d: resembles both stratified squamous and stratified cuboidal; basal cells cuboidal or columnar; surface cells dome shaped or squamouslike, depending on degree of organ stretch
f: stretches readily and permits distension of urinary organ by contained urine
L: lines the ureters, urinary bladder and part of urethra
embryonic connective tissue: mesenchyme
d: embryonic connective tissue; gel like ground substance containing fibers; star shaped mesenchymal cells
f: gives rise to all other connective tissue types
L; primarily in embryo
connective tissue proper: areolar
d: gell like matrix with all three fiber types; cells: fibroblasts, macrophages, mast cells and some white blood cells
f: wraps and cushions organs; its macrophages phagocytize bacteria; plays important role in inflammation; holds and conveys tissue fluid
L; widely distributed under epithelia of body (forms lamina propria of mucous membranes) packages organs, surrounds capillaries
connective tissue proper; adipose
d; matrix as in areolar, but very sparse; closely packed adipocytes or fat cells; have nucleus pushed to the side by large fat droplet
f; provides reserve fuel; insulates against heat loss; suports and protects organs
L; under skin; around kidneys and eyeballs, within abdomen and in breasts
connective tissue proper; reticular
d; network of reticular fibers in a typical loose ground substance; reticular cells lie on the network
f; fibres form a soft internal skeleton that supports other cell types including white blood cells, mast cells and macrophages
L; lymphoid organs (lymph nodes, bone marro and spleen)
connective tissue proper; dense regular
d; primarily parallel collagen fibers; a few elastic fibers; major cell type is the fibroblast
f; attaches muscles to bones or to muscles; attaches bones to bones; withstands great tensile stress when pulling force is applied in one direction
l: tendons, most ligaments aponeuroses
connective tissue proper; elastic
d; dense regular connective tissue containing a high proportion of elastic fibers
f; allows recoil of tissue following stretching; maintains pulsatitle flow of blood through arteries; aids passive recoil of lungsfollowing inspiration
l; walls of large arteries; within certain ligaments associated with the vertebral column; within the walls of the bronchial tubes
connective tissue proper; dense irregular
d; primarily irregularly arranged collagen fibers; some elastic fibers; major cell type is the fibroblast
f; able to withstand tension exerted in many directions; provides structural strength
l; fibrous capsules of organs and joints; dermis of the skin; submucosa of digestive tract
cartilage; hyaline
d; amorphous but firm matrix; collagen fibers form an imperceptible network; chondroblasts produce the matrix and when matrue lie in lacunae
f; supports and reinforces; serves as resillient cushion; resists compressive stress
l; forms most of the embryonic skeleton; covers the ends of long bones and joint cavities; forms costal cartilages of the ribs, noes, trachea and larynx
cartilage; elastic
d; similar to the hyaline cartilage but more elastic fibers in matrix
f; maintains the shape of a structure while allowing great flexibility
l: supports the outer ear; epiglottis
cartilage; fibrocartilage
d; matrix similar to but less firm than that in hayline cartilage; thick collagen fibers predominate
f; tensile strength with the ability to absorb compressive shock
l; intervertebral discs; pubic symphysis; discs of knee joint
osseous
d; hard calcified matrix containing many collagen fibers; osteocytes lie in the lacunae very well vascularized
f; bone supports and protects provides levers for the muscles to act on sotres calcium and other minerals with fat. marrow inside bones is the site for blood cell formation
l; bones
blood
d; red and white blood cells in a fluid matrix (plasma)
f; transport of respiratory gases, nutrients, enzymes and other substances
l; contained within blood vessels
skeletal muscle
d; long cylindrical, multinucleate cells; obvious striations
f; volunatry movement; locomotion; manipulation of the enviornment; facial expression, voluntary control
l; in skeletal muscels attached to bones or occasionally to skin
cardiac muscle
d; branching, striated, generally binucleate cells that interdigitate at specialized junctions called intercalated discs
f; as it contracts, it propels blood into the circulation; involuntary control
l; the walls of the heart
smooth muscle
d; spindle shaped cells with central nuclei; no striations; cells arranged closely to form sheets
f; propels substances or objects (food, urine a baby) along internal passageways; involuntary control
l; mostly in the walls of hollow organs
