Card Set Information
Chapter 4, tissues / epithelium
Simple Squamous Epithelium
: Single layer of flattened cells with disc shaped central nuclei and sparse cytoplasm.
: Allows passage of materials by diffusion and filtration.
: Kidney, air sacs of lungs, lining of heart, blood vessels and lymphatic vessels.
Simple Cuboidal Epithelium
: Single layer of cube like cells with large spherical central nuclei
: Secretion and absorption
: Kidney tubules, ducts, portions of small glands; ovary surface.
Name structures at E.O.P.
Goblet Cell & Cilia
Pseudostratified Columnar Epithelium Ciliated
: Single layer of cells of differeing heights, some not reaching the free surface; nuclei seen at different levels; may contain goblet cells or have cilia.
: Secretion, particularly of mucus; propulsion of mucus by ciliary action.
: Ciliated types line the trachea, most of the upper respiratiory tract.
Non ciliated types line male's sperm carrying ducts.
Stratified Squamous Epithelium Non Keratinized
: Thick membrane, surface cells are flattened. Non Keratinized type are wet.
: Protects underlying tissues in areas subject to abrasion.
: Nonkeratinized type forms the moist linings of esophagus, mouth and vagina.
Name tissue type
Stratified Squamous Epithelium Keratinized
: Thick membrane of flattened cells that are dead and contain keratin but no nuclei
: Protects underlying tissue
: Forms the epidermis of the skin, a dry membrane.
Stratified Cuboidal Epithelium
: Usually two layers of cube like cells
: Largest ducts of sweat glands, mammary glands and salivary glands.
: Resembles both stratitifed squamous and straitifed cuboidal. Surface cells dome shaped.
: Stretches amd permits distension of urinary organ by contained urine.
: Lines the ureters, bladder and part of the urethra.
Name the border between the epithelium and the connective tissue deep to it:
Supporting sheet called the Basal Lamina.
Thin, non cellular sheet of proteins secreted by epithelial cells.
The ______ _________ consists of the basal lamina and the reticular fibers of the underlying connective tissue.
The ____________ are finger like extension of the plasma membrane of apical epithelial cells and maximize surface area.
_________ are whip like extension of the apical surface membrane of certain epithelial cells.
Name the three cells found in Connective Tissue Proper:
Name the two types of cells found in cartilage:
Chondroblasts (found in growing cartilage)
Name the two types of cells found in Bone Tissue:
Name three types of cells found in Blood:
: Red Blood Cells
: White Blood Cells
Describe the matrix of Connective Tissue Proper:
Gel like substance.
All three fiber types
: collagen, reticular and elastic.
Descsribe the matrix of cartilage:
Gel like ground substance.
: collagen, elastic in some.
Describe the matrix of Bone Tissue:
Gel like ground substance calcified with inorganic calcium salts.
Describe the matrix of blood:
