Epithelium and Connective Tissue Flashcards
Simple layer of flat cells
simple squamous
Single layer of cubelike cells
Simple cuboidal
Single layer of tall cells
simple columnar
single layer but some cells are shorter than others
Pseudostratified
cells at the free edge are flattened
stratified squamous
shape of cells depend on the amount of stretching
transitional epithelium
bone cells in lacunae; hard matrix of calcium
Osseous tissue
abundant collagen fibers + rubbery matrix
Hyaline Cartilage
provides elasticity
elastic cartilage
highly compressible
fibrocartilage
main matrix is collagen fibers; cells are fibroblasts
dense connective tissue
soft, pliable tissue; contains all fiber types
Areolar connective tissue
surrounded by fluid matrix
Blood
fat globules, large lipid deposits
Adipose tissue
air sacs in lungs
simple squamous
Air passages (trachea)
pseudostratified
kidney tubules + ovaries
simple cuboidal
digestive tracts (intestines)
simple columnar
outer layer of skin
stratified squamous
urinary system
transitional
Binds skin to internal organs
areolar
tendons and ligaments
dense connective tissue
layer beneath the skin
adipose tissue
covers ends of bones
hyaline cartilage
external ear and epiglottis
elastic cartilage
vertebrate
fibrocartilage
skeleton
osseous tissue
circulates throughout body
blood
Diffusion
simple squamous
secretion and absorption
simple cuboidal + pseudostratified + simple columnar
protective covering where friction is formed
stratified squamous
Soak up excess fluid
areolar
insulation, protection, energy storage
adipose tissue
connect body parts together
dense connective tissue
reduces friction
hyaline cartilage
act as a cushion within joints
fibrocartilage
Protect and support the body
osseous tissue
transport vehicle for materials
blood
can be controlled voluntarily
Skeletal muscle
cells attach to bones by tendons
skeletal muscle
involuntary muscle
smooth and cardiac
found in the heart
cardiac muscle
function is to circulate blood + maintain blood pressure
cardiac muscle
found in blood vessels
smooth muscle
surrounds passageways
smooth muscle
moves food, urine, + reproductive secretions
smooth muscle
repair by dense fibrous connective tissue (scar)
Fibrosis
replacement of destroyed tissue by the same kind of cells
regeneration
tissue that regenerate easily
epithelial tissue + fibrous connective tissue and bone
tissues that regenerate poorly
skeletal muscle
tissues that are replaced largely w/ scar tissue
cardiac muscle + nervous tissue (brain + spinal cord)
