simple squamous epithelium

Simple squamous epithelium

Lines part of urethra, large excretory ducts of some glands, small areas in anal mucous membrane, and a part of the conjunctiva of the eye

Forms tendons (attach muscle to bone), most ligaments (attach bone to bone), and aponeuroses (sheet-like tendons that attach muscle to muscle or muscle to bone)

Subcutaneous layer of skin; papillary (superficial) region of dermis of skin; lamina propria of mucous membranes; and around blood vessels, nerves, and body organs

Forms superficial layer of skin

Lines a few portions of upper respiratory tract, uterine tubes, uterus, some paranasal sinuses, and central canal of spinal cord

Lines urinary bladder and portion of ureters and urethra

Lines larger ducts of many glands, epididymis, and part of male urethra

Lid on top of larynx (epiglottis), external ear (auricle), and auditory (Eustachian) tubes

Ends of long bones, anterior ends of ribs, nose, parts of larynx, trachea, bronchi, bronchial tubes, and embryonic skeleton

Lines heart, blood vessels, lymphatic vessels, air sacs of lungs, glomerular (Bowman's) capsule of kidneys, and inner surface of the tympanic membrane (eardrum); forms epithelial layer of serous membranes

Lines wet surfaces, such as lining of the mouth, esophagus, part of epiglottis, and vagina, and covers the tongue

Subcutaneous layer deep to skin, around heart and kidneys, yellow marrow of long bones, and padding around joints and behind eyeball in eye socket

Stroma (supporting framework) of liver, spleen, lymph nodes; portion of bone marrow that gives rise to blood cells; reticular lamina of the basement membrane; and around blood vessels and muscle

Lines the gastrointestinal tract from the stomach to the anus, ducts of many glands, and gallbladder

Fasciae (tissue beneath skin and around muscles and other organs), reticular (deeper) region of dermis of skin, periosteum of bone, perichondrium of cartilage, joint capsules, membrane capsules around various organs (kidneys, liver, testes, lymph nodes), pericardium of the heart, and heart valves

Lung tissue, walls of elastic arteries, trachea, bronchial tubes, true vocal cords, suspensory ligament of penis, and ligaments between vertebrae

Pubic symphysis (point where hipbones join anteriorly), intervertebral discs (discs between vertebrae), menisci (cartilage pads) of knee, and portions of tendons that insert into cartilage

Ducts of adult sweat glands and part of male urethra

Lines the airways of most of the upper respiratory tract

Covers surface of ovary, lines anterior surface of capsule of the lens of the eye, forms the pigmented epithelium at the back of the eye, lines kidney tubules and smaller ducts of many glands, and makes up the secreting portion of some glands such as they thyroid gland

Simple cuboidal epithelium
