Histology Flashcards
What are the four categories of tissues?
epithelial, connective, muscle, nervous
What does the Epithelial tissues include?
simple, stratified, pseudostratified, transitional, glandular
What are the shapes of epithelial tissue?
squamous, cuboidal, columnar
what are the three types of connective tissues?
protein fibers, mixed, fluid
what do the protein fibers include?
dense, loose, adipose, reticular
what do the mixed tissues include?
cartilage, bone, fluid
What are the only fluid connective tissues we have?
blood
what are the 3 types of muscle tissue?
skeletal, smooth, cardiac
what are the types of nervous tissue?
glial, neuron
An epithelial tissue that has one layer
simple
An epithelial tissue that has many layers
stratified
filling between the cells
interstitial/ extracellular matrix
Most abundant tissue in the body
connective tissue
Where are connective tissues found?
throughout the body
What are connective tissues composed of?
Scattered cells with abundant intercellular material
What are the functions of connective tissues? (9)
bind structures, support, framework, fill spaces, store fat, produce blood cells, protects against infection, repairs tissue damage
produced by connective tissue cells and excreted to their exterior, separates living cells
extracellular matrix
what does the extracellular matrix consist of?
ground substances and fibers
composed of water and adhesion proteins
ground substance
allowing connective tissue cells to attach themselves to the matrix fibers embedded in the ground substance
adhesion proteins
strands of collagen, elastin, or reticular protein
protein fibers
mixture of fibers and hard mineral deposits
protein fibers and ground substance
loose
areolar
refers to cartilage
chondro
space
lacunae
what are the 2 categories of connective tissues?
dense and loose
what do dense protein fiber matrix include?
regular and irregular
attachment for basement memberane
loose
protein matrix with fat containing cells scattered throughout
adipose
netlike meshwork of the collagen fibers that helps hold tissues in place and sometimes helps to filter particles from fluids passing through it
reticular
what are the types of mixed matrix?
cartilage and bone
what are 3 types of cartilage?
elastic, hyaline, fibrocartilage
external ear, parts of larynx
elastic
ends of bones, joint linings
hyaline
invertebral disks, knees and pelvic girdle
fibrocartilage
cartilage cells; lie within lacunae
chondrocytes
