changes shape

Multiple layers of polyhedral cells, or flattened cells; some cells may be binucleated

Location

Air sacs in lungs, lining of heart chambers and lumen of blood vessesl, serous membranes of body cavities

Simple Cuboidal Epithelium

Ciliated form lines most of respiratory tract, including nasal cavity, part of pharynx, larynx, trachea, bronchi.

Non ciliated form is rare; lines epididymis and prat of male urethra

originate from an invagination of epithelium that burrows into the deeper connective tissues.

Contain ducts that secrete materials onto the surface of the skin

1) form and structure

2) type of secretion

3) method of secretion

package their secretions in structures called secretory vesicles

Ex:  Lacrimal glands, salivary glands, some sweat glands, the exocrine glands of the pancrease, and the gastric glands of the stomach

a merocrine gland that is

a type of sweat gland in the skin that is not connected to a hair follicle

are formed from cells that accumulate a product and then the entire cell disintegrates.

EX:  The oil-producing glands (sebaceous glands) in the skin

(The oily secretion you feel on your skin is actually composed of ruptured, dead cells)

are composed of cells that accumulate their secretory products within the apical portion of their cytoplasm.

Ex:  Mammary glands and some sweat glands in the axillary and pubic regions

cells

protein fibers

ground substance

Throughout the body of the embryo, fetus, and adult

Common origin for all othe connective tissue types

Umbilical Cord of Fetus

Support of structures in umbilical cord attaching fetus to mother

are permanently contained within the connective tissue

Help support, maintain, and repair the extracellular matrix

Move throughout the connective tissue

immune protection and repair of damaged extracellular matrix

large

relatvely flat cells with tapered ends

resident cells

Produce the fibers and ground substance componenets of the extracellular matrix

Store lipid reserves

Phagocytize foreign material

Large cells derived from monocytes in blood

Divide in response to injury to produce new connective tissue cells

Stellate or spindle-shape embryonic stem cells

Surrounding nerves, vessels, subcutaneous layer of the skin

Binds and packs around organs

Subcutaneous layer, surrounding kidney and selected other organs

Protects, stores fat, insulates

Stroma of spleen, liver, lymph nodes, bone marrow

Forms stroma of lymphatic organs

Tendons and ligaments

Provides great strength and flexibility primarily in a single direction

Deep portion of the dermis, supportin layer around cartilage and around bone, houses internal organs (liver, kidneys and spleen)

Provides tensile strength in all directions

Provides framework and supports organs

EX:  vocal cords, the suspensory ligament of the penis, and some ligaments of the spinal column, walls of large arteries

Mature cartilage

avascular (without blood vessels)

Hyaline

Fibrocartilage

Elastic

most common and weakest

Supports soft tissue

forms most of the fetal skeleton

found in the nose, trachea, most of the larynx, costal cartilage (ribs) and the articular ends of long bones

Found in intervertebral discs, pubic symphysis, menisci of the knee joint

Acts as a shock absorber and resists compressions

Throughout the body of the embryo, fetus, and adult

Common origin for all other CT types

cells

protein fibers

ground substance

Umbilical cord of fetus

Support of structures in umbilical cord attaching fetus to mother

also called a mucosa

lines body passageways and compartments that eventually open to the external environment

EX:  digestive, respiratory, reproductive, and urinary tracts

also termed a serosa

simple squamous epithelium (mesothelium) produce a watery serous fluid which is derived from blood plasma.

EX: pericardium, peritoneum, and pleura

Largest body membrane - skin

keratinized stratifited squamous epithelium (epidermis)

and a layer of CT (dermis)

Lines joint cavity and distributes nutrients to the cartilage on the joint surfaces of the bone

Attaches to bones or sometimes to skin (facial) also found in the voluntary sphincters - lips, urethra, anus

striated

voluntary body movements

Heart Wall (myocardium)

Involuntary contraction and relaxation

short, bifurcated,striated

Walls of hollow internal organs, such as vessels, airways, stomach, bladder, uterus

spindle-shaped, nonstriated

also termed neural tissue

consists of cells called neurons (nerve cells)

and glial cells (supporting cells)

What type of epithelium

 is adapted for diffusion and filtration
