Tissues Flashcards
Stratified Squamous Epithelium
Multiple layers (flat at free edge)
Skin, mouth, esophagus
Protective covering, friction common
Simple Squamous Epithelium
Single layer, flat
Forms membranes
Lines body cavities
Lines lungs and capillaries
Simple Cuboidal Epithelium
Single layer, cube like
Glands, ducts
Kidney tubules
Ovaries
Simple Columnar Epithelium
Single layer, tall
Includes goblet cells (mucous)
Digestive tracts
Pseudostratified Epithelium
Single layer, uneven nucleus
Ciliated sometimes (respiratory tract)
Non-ciliated (sperm carrying ducts)
Absorption, secretion
Stratified Cuboidal Epithelium
Two layers cuboidal cells
Two rows round nuclei
Sweat glands, mammary glands, salivary glands
Stratified Columnar Epithelium
Surface cells columnar, below is cuboidal
Large ducts, pharynx, male urethra
Transitional Epithelium
Relaxed cuboidal, stretched squamous
Urinary tract, bladder
Bone
Connective
Protect support
Hard calcified matrix
Many collagen fibers
Hyaline Cartilage
Connective Abundant collagen fibers Rubbery matrix Fetal skeleton, nose, ribs>sternum, respiratory passages Support, some pliability
Elastic Cartilage
Connective
Elasticity
Strength, exceptional stretchability
External ear, epiglottis
Fibrocartilage
Connective
Highly compressible
Intervertebral discs
Dense connective tissue (regular)
Collagen fibers
Fibroblasts
Parallel fibers
Tendons, ligaments
Dense connective tissue (irregular)
Fibers multiple directions, thicker
Collagen fibers, elastic fibers
Fibroblasts
Fibrous capsules, reticular dermis, submucosa
Areolar connective tissue
Most wisely distributed
Soft, pliable
All fiber types
