Chapter 5 - Tissues Flashcards
What are the four major types of tissues?
Epithelial, Connective, Muscle, Nervous
Widespread throughout the body, covers organs, and lines body surfaces
Epithelial tissue
Anchored to a basement membrane, made up of tightly packed cells containing little intercellular material, generally lack blood vessels, and are replaced frequently
Epithelial tissue
Function in protection, secretion, absorption, excretion, and sensory reception
Epithelial tissue
Made up of a single layer of thin, flattened cells
Simple Squamous Epithelium
Because it is suited for diffusion, it functions in the exchange of gases in the lungs and lines blood and lymph vessels as well as body cavities
Simple Squamous Epithelium
Consists of a single layer of cube-shaped cells with centrally located nuclei
Simple Cuboidal Epithelium
Functions in secretion and absorption in the kidneys, and in secretion in glands
Simple Cuboidal Epithelium
Made up of a row of elongated cells whose nuclei are all located near the basement membrane. It may be ciliated
Simple Columnar Epithelium
Lines the uterus, stomach, and intestines where it protects underlying tissues, secretes digestive fluids, and absorbs nutrients
Simple Columnar Epithelium
These cells appear layered due to the varying positions of their nuclei within the row of cells, but are not truly layered
Pseudo-stratified Columnar Epithelium
Cilia may be present, along with mucus-secreting goblet cells, that line and sweep debris from respiratory tubes
Pseudo-stratified Columnar Epithelium
Made up of layers of flattened cells that are designed to protect underlying layers
Stratified Squamous Epithelium
Makes up the outer layer of skin, and lines the mouth, throat, vagina, and anal canal
Stratified Squamous Epithelium
Consists of 2-3 layers of cuboidal cells lining a lumen of the mammary glands, sweat glands, salivary glands, and pancreas
Stratified Cuboidal Epithelium
Consists of several layers of cells and is found in the vas deferens, part of the male urethra, and parts of the pharynx
Stratified Columnar Epithelium
Designed to distend and return to its normal size, as it does in the lining of the urinary bladder
Transitional Epithelium
