Epithelial, connective, muscle, and nervous.
Are highly branched and form delicate supporting networks in a variety of tissues.

knees and in the pelvic girdle
Is only in in the heart.
Cardiac muscle tissue
Are farther apart than epithelial cells, and have abundant extracellular matrix between them.
Connective tissues
Consists of a single layer of cube-shaped cells.
Simple cuboidal epithelium
Has sparse collagenous fibers
loose connective tissue
Dendrites respond by
transmitting electrical impulses along cellular processes called axons.

Resemblance to glass (EX: hyaline cartilage)
Lines the oral cavity.
Stratified squamous epithelium
Thin collagenous fibers
Reticular fibers
Channels that link cytoplasm of adjacent cells.
Gap junctions
Cartilage tissue lacks…
direct blood supply
Consists of many closely packed, thick, collagenous fibers; a fine network of elastic fibers; and a few cells, mostly fibroblasts.
Dense regular connective tissue
Cartilage cells lie completely within the..
extracellular matrix
Typically watery and has a high concentration of enzymes.
Serous fluid
The three types of cartilage
Hyaline, Elastic, and FIbrocartilage
Histamine is a substance that promotes some of the reactions associated with
inflammation and allergies
Definition: chondr-
Cartilage (EX: chondrocyte - cartilage cell)
Are tightly packed.
Epithelial cells
Lines part of the nasal cavity.
Pseudostratified columnar epithelium
Found in inner lining of the urinary bladder and lines ureters & superior urethra.
Transitional epithelium
Rich in glycoprotein mucin.
Mucus
Divide and are crucial to the functioning of neurons.
Neuroglia
Bloods includes three types of cells.
Red blood cells, white blood cells, and cellular fragments called platelets.
Histamine stimulates inflammation by dilating the small…
arterioles that feed capillaries
Are important components of the body parts that hold structures together, such as ligaments and tendons.
Collagenous fibers
Includes loose connective tissue and dense connective tissue.
Connective tissue proper
Cartilage cells occupy small chambers called…
Lacunae
Definition: adip-
Adipose tissue - tissue that stores fat
Underlies most layers of epithelium, where its many blood vessels nourish nearby epithelial cells.
Areolar connective tissue
As scavenger cells, they can clear foreign particles from tissues, providing an important defense against infection.
Macrophages
Hyaline cartilage is important in the development and growth of most…
bones.
The fibers are thicker, interwoven, and more randomly organized
Dense irregular connective tissue
A rigid connective tissue
Cartilage
Originate as white blood cells and are almost as numerous as fibroblasts in some connective tissues.
Macrophages
Definition: Os-
Bone
Lines the small intestine.
Simple columnar epithelium
Cells of serous membranes secrete watery
serous fluid
Transitional epithelium forms a barrier that helps prevent contents of urinary tract from…
Diffusing back into internal environment.
Also release histamine
Mast cells
Are large and widely distributed in connective tissues; are usually near blood vessels.
Mast cells
Contractile; can shorten and thicken.
Muscle tissues
Definition: Phag-
To eat
Fibroblast and mast cells are considered…
fixed cells
Is found on the ends of bones in many joints, in the soft part of the nose, and in the supporting rings of the respiratory passages.
Hyaline cartilage
Deeper layers of stratified squamous epithelium are…
Cuboidal or columnar
Tissue containing abundant collagenous fibers is called
dense connective tissue
Forms muscles that usually attach to bones.
Skeletal muscle tissue
The three major types of epithelial membranes are…
serous, mucous, and cutaneous
Definition: -cyt
Cell (ex: osteaocyte- bone cell)
Smooth muscle tissues comprise the walls of…
hollow internal organs
Epithelium lines the…
Hollow organs
Intercellular junctions
Structures that connect cell membranes of certain cell types.
Definition: Strat-
Layer (EX: stratified epithelium - tissue with cells in layers.)
Reticular connective tissue helps prove the…
framework of certain organs
Noncilitated simple columnar epithelium lines the…
Uterus and portions of the digestive tract
Adipose tissue lies…
beneath the skin.
These fibers branch, forming complex networks in various tissues.
Elastic fibers
Also lines the oral cavity, esophagus, vagina and anal canal.
Stratified squamous epithelium
Is found in the subcutaneous layer beneath the skin and surrounding organs.
Areolar connective tissue
Cannot be stimulated to contract by conscious effort.
Smooth muscle tissue
Simple columnar epithelium secretes…
Digestive fluids
Secrete their products into tissue fluids or blood.
Endocrine glands
Stratified columnar epithelium lines larger…
Ducts of exocrine glands
Form the inner lining of the thorax and abdomen and cover the organs in these cavities.
Serous membranes
Single layer of thin, flattened cells.
Simple squamous epithelium
Where one cell touches another cell is a specialized intercellular junction called an…
intercalated disk (seen only in cardiac tissue)
