primary tissues
epithelial, connective, nervous and muscular
matrix (extracellular material)
material surrounding the cells and composed of the fibrous proteins and ground substance
a chemical like formalin that prevents decay and makes the tissues more firm
enhances detail
longitudinal section
tissue cut in the long direction
cross section (transverse section)
tissue cut perpendicular to the longitudinal section
oblique section
cut in between the longitudinal and cross sections, at an angle
the tissue is rubbed or spread across the slide rather than sliced
the tissue is laid out on the slide; placing a small square of tissue paper or tuft of lint on a sheet of glass
type of tissue composed of one or more layers of cells either covering an organ surfaceor forming the secretory tissue and ducts of a gland
basement membrane
between the epithelium and the connective tissue
simple squamous
thin flat scaly cells
simple cuboidal
square or round cells
simple columnar
tall narrow cells
pseudostratified columnar epithelium
not all cells reach the free surface and the taller cells cover the shorter ones
goblet cells
produce protective mucous over the mucous membranes
stratified epithelia
range from 2-20 layers and only the deepest layer reaching the basement membrane
stratified squamous
two kinds- keratinized and non-keritinized and are flat multi-layered cells
stratified cuboidal
multi-layered square or round cells
stratified columnar
rare but found in the pharynx, larynx, anal canal and male urethra
found on the skin surface, which are alive and covered with a layer of compact dead squamous cells
lackes the surface layer of dead cells. Are exfoliated and dead.
connective tissue
ususally occupy less space and fall into 3 categories: fiborous ct, supportive ct, and fluid ct
3 types of protein fibers: collagenous fibers made of collagen, reticular and are thin fibers coated with glycoprotein and elastic and made of elastin able to stretch and shrink back to small size
fiborous ct
two types: loose and dense
loose ct
areolar, reticular and adipose tissue and there is much space occupied by ground substance
dense ct
the fibers occupy more space than the cells and ground substance. There is regular and irregular
regular dense ct
the collagen fibers are closely packed and leave relatively little open space and the fibers are parallel to each other
irregular dense ct
thick bundles of collagen and little room for cells and ground substance but the collagen bundles run in different directions
reticular tissue
mesh of reticular fibers and fibroblasts and forms the structural framework of organs and tissues like lymph nodes, spleen, thymus, and bone marrow
adipose tissue
adipocytes are the dominant cell and may occur singly or in small clusters in areolar tissue
supportive connective tissue with a flexible rubbery matrix and gives shape to external ear
secrete the matrix and surround themselves with it until they become trapped in little cavities called lacunae and when they are enclosed here are called chondrocytes
hyaline cartilage
clear and glassy appearance
elastic cartilage
conspicuous elastic fibers
coarse and readily visible bundles of collagen
dense irregular connective tissue that surrounds the elastic cartilage and most hyaline cartilage
osseous tissue
makes up most of the mass of a bone
spongy bone
fills the heads of long bones
compact (dense) bone
more dense calcified tissue with no spaces visible to the naked eye
central canal
run longitudinally through the shafts of long bones like the femur
onionlike layers around each central canal
central canal and its surrounding lamellae
mature bone cells
delicate canals and radiate from lacunas to its neighbors and allows osteocytes to contact each other
liquid connective tissue that travels through tubular vessels and transports cells and disolved matter from place to place
ground substance of which is linked with blood
formed elements
cells and cell fragments
red bloos cells
white blood cells
small cell fragments scattered amid the red blood cells and are involved with clotting and other mechanisms for minimizing blood loss
