Tissues Flashcards
*lining of blood vessels, heart (endothelium), lymph vessels, and alveoli of lungs; peritoneum
*single layer of flattened cells
*diffusion; filtration; secretion of lubricants
Simple Squamous
*ducts, secretory part of small glands; retina; kidney tubules; ovaries, testes; bronchioles
*single layer of squarish cells
*secretion; absorption
Simple Cuboidal
*ducts, glands; gut; small bronchi
*single layer of tall cells; free surface may have cilia or microvilli
*secretion; absorption; ciliated types move substances
simple columnar
*Trachea
*single layer of tall cells that look like they have differing heights, some not reaching the basal surface; nuclei seen at different levels
*secretion (mucus); propulsion of mucus by ciliary action
Pseudostratified Ciliated columnar
*lines the ureters, urinary bladder
*binucleated, “fluffy” cells that can change their geometry in response to tensional forces
*stretches readily and permits swelling/enlarging of urinary organ
Transitional Epithelium
*esophagus
*many stacked layers of squamous epithelium. Defined basal membrane
*living cells act as a protective barrier
Non-Keratinized Stratified Squamous Epithelium
There is something special about Non-keratinized Stratified Squamous Epithelium, what is it?
it must be kept moist
*skin
*protective barrier from abrasion and water loss
*thick layers of stratified squamous with waterproof keratin border
Keratinized Stratified Squamous Epithelium
*pituitary, thymus, pancreas
*secrete hormones directly into the bloodstream
Endocrine gland
*sweat, mammary, salivary, pancreas
*secrete a product onto a surface
exocrine gland
*under skin
*connect/serve as an anchor
*collagen and elastic fibers
Loose (areolar) Connective Tissue
*around organs
*insulation, energy, storage
*loose elastic and collagen fibers
Adipose Connective Tissue
*tendons and ligaments
*connects muscle to bone (tendon) and bone to bone (ligament
*densely packed collagen fibers
Dense Regular Connective tissue
*dermis of the skin
*connect epithelial tissue to the bone
*densely packed collagen fibers
Dense irregular Connective Tissue
*nose, fetal skeleton, ends of long bones
*movement
*thin collagen fibers
Hyaline cartilage connective tissue
*outer ear
*elasticity/flexibility
*mainly elastic fibers
Elastic Cartilage Connective Tissue
*disks of vertebrae, knee joint
*Movement
*strong collagen fibers
Fibrocartilage Connective Tissue
*ends of long bones (femur)
*Protection
*collagen and calcium salts
Spongy Bone Connective Tissue
*shafts of long bones (femur)
*Protection
*collagen and calcium salts
Compact Bones Connective Tissue
*blood vessels and heart
*transport gases, immunity, blood clotting proteins
*plasma
blood
*lymphatic tissue
*white blood cells congregate here (immunity)
*lymph
Lymph
*partner of bones (biceps, triceps, etc.)
*movement voluntary, striated
Skeletal Muscle
*heart
*pump blood involuntary, striated
cardiac muscle
*hollow organs, blood vessels
*blood flow in arteries is involuntary, lacks striations
Smooth Muscle
