Anatomy Unit 3 - tissues

Epithelial tissue

Covers the body surfaces and lines cavities

nervous tissue

Has supportive cells called glia

Connective tissue

Tendons and ligaments belong to this tissue

Epithelial tissue

cells can be flat, cubes, or rectangles

muscle tissue

major function is movement

Epithelial tissue

involved in absorbing gases or nutrients

connective tissue

adipose, which provides protection, insulation, and storage of fat, belongs to this tissue

nervous tissue

receives stimuli, transports impulses, and interprets nerve impulses

epithelial tissue

includes a type of cell found in the lining of the urinary bladder and uretor and is

simple squamous epithelium

nervous tissue

bone

skeletal muscle

hyaline cartilage

reticular tissue

simple cuboidal epithelium

adipose tissue

transitional epithelium

blood

elastic cartilage

stratified cuboidal epithelium

fibrocartilage

cardiac muscle

smooth muscle

stratified columnar epithelium

areolar connective tissue

simple cuboidal epithelium

forms tubules in kidneys

stratified squamous epithelium

forms top layer of skin

transitional epithelium

lines urinary bladder

simple columnar epithelium

contains goblet cells that create a protective mucus lining in the respiratory and lower digestive tracts

simple squamous epithelium

forms serous membranes (the outer lining of organs and body cavities)

connective tissue

the tissue under epithelium

transitional epithelium

epithelium that stretches and relaxes

Lamina Lucida

the section of basal lamina that contains glycoproteins and attaches epithelium to the underlying connective tissue

goblet cells

cells that secrete mucus

simple squamous

single layer of scale like cells packed close together

simple squamous location

alveoli of lungs, serous membranes

simple squamous function

function is to allow gases to pass through diffusion

simple cuboidal epithelium

cube-shaped cells with large central nucleus, organized into tubules. Basal Lamina may be visible

simple cuboidal location

kidney tubules

simple cuboidal function

function is secretion and absorption

simple columnar (non-cilliated)

single layer of oval shaped cells, attached to the basement membrane

simple columnar location

digestive tract

simple columnar function

function is absorption of nutrients, and secretion of digestive juices

pseudostratified columnar epithelium

single layer of cells all touching basal lamina but not all touching free surface. Nuclei distributed throughout causing stratified appearance

pseudostratified columnar epithelium location

trachea of respiratory tract (ciliated), ducts of male reproductive system

pseudostratified columnar epithelium function

function is protection, secretion, cilia movement

transitional epithelium

single layer of cells all touching basal lamina but not all touching free surface. Nuclei distributed throughout causing stratified appearance

transitional epithelium location

urinary bladder

transitional epithelium function

function is stretching and recoiling without breaking

stratified squamous

multiple layers of flat cells; outer most layer

stratified squamous location

mouth, esophagus, anus lining

stratified squamous function

function is protection of underlying structures

stratified cuboidal epithelium

multiple layers of cube shaped cells

stratified cuboidal location

rare, may line sweat-gland ducts

stratified cuboidal function

function is protection, secretion

stratified columnar epithelium

multiple layers of columnar cells

stratified columnar location

pharynx, epiglottis, anus, mammary glands, salivary gland ducts, urethra

stratified columnar function

function is to protect

collagen fiber

protein fiber for strength

perichondrium

outer membrane of cartilage

osteon

column of bone tissue

lacuna

small space surrounding cell

fibroblast

produces matrix fibers

matrix

extracellular material

elastic fiber

protein fiber for flexibility

ground substance

syrupy fluid of matrix

mast cell

causes inflamation

canaliculi

nutrient channels in bone matrix

adipose connective tissue

cells in which nucleus and cytoplasm are pushed against cell membrane

matrix in elastic cartilage

elastic fibers, and syrupy ground substance

three major groups of connective tissue

connective tissue, supportive connective tissue, fluid connective tissue

examples of 3 major connective tissues

connective - adipose, supportive connective - bone, fluid connective - blood

areolar tissue

cell types in this tissue include mast cells, fibroblasts, and macrophages

bone

solid matrix, lamellae surrounding central canals

fibrous cartilage

found in intervertebral disks, chondrocytes stacked inside lacunae

dense regular connective tissue

parallel bundles of collagen fibers with fibroblasts between fibers

elastic cartilage

gelatinous matrix, chondrocytes in lacunae, elastic fibers in matrix

reticular tissue

many cells among network of reticular fibers
