Simple columnar epithelium Simple cuboidal epithelium Simple squamous epithelium Pseudostratified columnar epithelium Stratified squamous Epithelium Transitional epithelium Epithelial Tissue • Consists of several layers of cube shaped, elongated, and irregular cells • Commonly possess cilia that move sex cells and mucus • Single layer flattened cells • Nuclei located at different levels within cells • Forms walls of capillaries and air sacs of lungs • Forms lining of trachea and bronchi • Younger cells cuboidal, older cells flattened • Form inner lining of urinary bladder • Lines kidney tubules and ducts of salivary glands • Forms lining of stomach and intestines • Nuclei located near basement membrane • Forms lining of oral cavity, anal canal, and vagina

Adipose tissue Blood Bone Dense connective tissue Cartilage Elastic connective tissue Loose (areolar)connective tissue Connective Tissue • Form framework of outer ear • Functions as heat insulator beneath skin • Contains large amounts of fluid and lacks fiber • Cells arranged around central canal • Binds skin to underlying organs • Provides stored enerdy supply in fat vacuoles • Forms the flexible part of the nasal septum • Pads between vertebrae that are shock absorbers • Forms supporting rings of respiratory passages • Cells greatly enlarged with nuclei pushed to sides • Matrix contains collagen fibers and mineral salts • Occurs in ligament attachments between vertebrae and artery walls • Hyaline, elastic, fibro
Adipose Bone Hyaline cartilage Blood

Cardiac muscle Nervous tissue Skeletal muscle Smooth muscle Muscle and Nervous Tissue • Coordinates, regulates, and integrates body functions • Contains intercalated discs • Muscle that lacks striations • Striated and involuntary • Striated and voluntary • Contains neurons and neuroglial cells • Muscle attached to bones • Muscle that composes heart • Moves food through the digestive tract • Transmits impulses along cytoplasmic extensions
