Epithelium Tightly packed cells functioning as covering and lining tissues. Always found as a surface tissue
Connective tissue Few cells with lots of extracellular material; many functions.
Muscle Elongated cells specilized to shorten(contract)
Nervous tissue Wirelike cells specialized for conduction of electrical signals. Brain, spial cord, and nerves.
Cell shape - SQUAMOUS Flat
Cell shape - CUBOIDAL Cube
Cell shape - COLUMNAR Column
Simple One layer
Stratified Multiple layers
Functions of epithelial tissues Secretion, absorption, excretion, protection.
Simple squamous epithelium Single layer of flat cells. Forms the lining of cardiovascular system. It is the tissue always in contact with blood as it moves through the body.
Simple cuboidal epithelium Single layer of cubed cells. Lining of many glands of the body. Sometimes called glandular epithelium.
Simple columnar epithelium Single layer of tall columnar cells. Inner lining of digestive tract. Cilia covered surface lining the brochi of the lungs and the uterine tubes.
Four basic types of connective tissue Connective tissue proper(soft) - Cartilage(rubbery) - Bone(hard) - Blood(fluid)
2 types of connective tissue proper Fixed and Wandering
Types of fixed cells Fibrocytes and Adipose
Fibrocytes are... The main cell of connective tissue. Cells that produce extracellular fibers.
Adipose cells are... Cells specialized to store lipid energy reserves(FAT)
Wandering cells are... Body defense and repair cells of the white blood cell lineage.
Interfibrillar substance Water with various suspended molecules between the fibers.
Collagen fibers Very strong in tension, not strong in compression.
Elastic fibers String-like or sheet-like branched proteins, stretchy
5 types of connective tissue proper Loose collagenous connective tissue - Dense irregular collagenous connective tissue - Dense regular collagenous connective tissue - Elastic tissue - Adipose tissue(fat)
Cartilage Lack internal blood supply. Resists compression, not strong with tension.
3 types of cartilage Hyaline - Fibrocartilage - Elastic
Which cartilage is the most common in the body? Hyaline
