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
Stratified squamous
•
Form inner lining of urinary bladder
Epithelium
•
Lines kidney tubules and ducts of salivary glands
Transitional epithelium
•
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
Cartilage
•
Forms the flexible part of the nasal septum
Elastic connective
tissue
•
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
Cardiac muscle
Nervous tissue
Skeletal muscle
Smooth muscle
•
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
