What is the function of Stratified squamous?
designed to portect underlying layers
What do stratified squamous look like?
Thick, flattened associated with Keratin.
Where are Stratified Cuboidal found?
Lining of Lumen, Mammary glands, sweat glands, salivary glands, and pancreaus.
what is the function of stratified Cuboidal?
Protections
where are stratified columnar found?
Male Urethra, and pharynx
What do stratified columnar look like?
superficial layers are columnar and basal layers are cuboidal.
What do stratified cuboidal look like?
two or three layers of cubodial tissue.
Where are transitional cells found?
Urinary bladder
What is the function of Transitional Cells?
Stretch and expand
where are Glandular cells found?
usually found within the columnar and cuboidal epithelia.
What is the function of Glanular cell tissue?
Produces and secretes substances into ducts and body fluids
What is Exocrine?
a gland that secretes into the ducts
What is Exdocrine?
A gland that secretes into blood
What are the characteristics of Connective tissue?
Binds and supports, provides framwork, fills spaces, stores fat, produces blood, protects against infection, repairs tissue, Abundant matrix(intercellular material) good blood supply
What is Fibroblast?
A connective tissue cell that is starlike and produces fibers by secreting porteins into the extracellular matrix
What is the function of Fibroblast?
Defends against function by wandering macrophages.
What do stratified squamous look like?
Thick, flattened associated with Keratin.

What is Exdocrine?
A gland that secretes into blood
What are the characteristics of Connective tissue?
Binds and supports, provides framwork, fills spaces, stores fat, produces blood, protects against infection, repairs tissue, Abundant matrix(intercellular material) good blood supply
What is Fibroblast?
A fixed connective tissue cell that is starlike and produces fibers by secreting porteins into the extracellular matrix
What are Mast Cells?
they are cells of connective tissue that are fixed they are located near blood vessels they release heparinand histamine
What are macrophages?
Wandering connective tissue cells that originated as a white blood cells and carry on phagocytosis. they remove foreign particles from tissue to fight infection
What is the function of Loose connective tissue?
binds skin to the underlying organs and fills the spaces between the muscles
What does loose connective tissue look like?
the cells of this tissue are mainly fibroblast located far apart, gel like extracellular matrix that contains many collagenous and elastic fibers.
What is Adipose tissue?
Specialized loose connective tissue that stores fat in droplets within in cytoplasm nucleus is pushed to the side
Where is adipose tissue found?
Beneath the skin around joints padding for the kidneys and other internal organs.
What is Dense connective tissue?
Closely packed collagenous fibers very strongs but lacks blood supply
Where is Dense tissue found?
Tendons and ligaments
What is Cartilage?
Rigid connective tissue known also as Chondrocytes. these cells lie within the lacunae in the gel like matrix or Fluid Matrix poor blood supply
What is the function of Cartilage?
