Ch. 5 Histology

Epithelial Tissue

Tissue that covers outside of the body and lines organs and cavities.

Connective Tissue

Mostly matrix with cells to support, protect and bind organs

Nervous Tissue

Excitable cells for rapid transmission of info

Muscular Tissue

Contracts and moves the various parts of the body.

Epithelial tissue lies on loose vessel rich _.

Connective Tissue

Basement membrane

Lies between epithelial and connective tissue to anchor, control exchange, and develop epithelial.

Simple squamous

single layer of flat cells

simple cuboidal

single layer of cube shaped cells

simple columnar

Single layer of tall cells

psudostratified columnar

Appears stratified but all cells touch basement membrane. Found in Respiratory tract.

keratinized stratified squamous epithelium

Multi layer of flat cells and keratin to keep dry. found in epidermis

nonkeratinized stratified squamous epithelium

Multi layer of flat cells. area is moist and slippery, abrasion resistant. found on tongue.

stratified cuboidal epithelium

tissue that consists of two or more layers of cube-shaped cells, found in some ducts

Urothelium (transitional epithelium)

Multilayered epithelium with surface cells that change from round to flat when stretched.

Allows for filling of urinary tract

Location: ureter and bladder

Areolar Tissue

Binds skin to underlying organs. found throughout the body

reticular tissue

type of loose connective tissue that provides a supportive framework to soft organs, such as lymphatic tissue, spleen.

dense regular connective tissue

Function: attaches muscles to bones or to muscles; attaches bones to bones; withstands great tensile stress when pulling force is applied in one direction

dense regular connective tissue

Location: tendons, most ligaments, aponeuroses

Tendon

Connects muscle to bone

Ligament

Connects bone to bone

dense irregular connective

thick bundles of collagen that run in random order. see in dermis and organ capsules

Adipose Tissue

Tissue that stores fat.

hyaline cartilage

clear glassy appearance, seen on ends of bones and rings around trachea.

Elastic cartilage

cartilage with abundant elastic fibers; see at the ears and nose

Fibrocartilage

cartilage that contains fibrous bundles of collagen, such as that of the pubic symphyses and spinal discs.

Bone Tissue

AKA osseous tissue

Blood's ground substance

plasma

Formed elements of blood

erythrocytes, leukocytes, platelets

Nervous Tissue

Electrochemical cells for transporting messages.

Skeletal Muscle

striated and voluntary

cardiac muscle

Striated, involuntary muscle found only in the heart

smooth muscle

Involuntary and non striated muscle found inside many internal organs of the body
