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

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

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
