Tissues

Tissues

A group of similar cells that perform a common function

matrix

Kind of fluid material between cells

collagen

Protein that forms microscopic twisted ropes within the matrix of many tissues

Elastin

Present in some tissues, and it's rubbery quality gives tissues the ability to stretch and rebound easily

Proteoglycans

Provides the tissues with specialized properties, in the matrix

epithelial tissue

Forms sheets that cover the body and many of its parts

interstitial fluid

fluid in the spaces between cells

basement membrane

Connect epithelial tissue to its connective tissue foundation. This is a glue-like layer.

Squamous

Flat and scale like

Cuboidal

Cube shaped

Columnar

More tall than wide

transitional

Varying shapes that can stretch

simple

A single layer of cells of the same shape

stratified

Many layers of cells, named for the shape of cells in the outer layer

simple squamous epithelium

Consists of a single layer of very thin and irregular shaped cells

stratified squamous epithelium

Consists of several layers of closely packed cells, and arrangement that makes this tissue, especially adept at protection

simple cuboidal epithelium

Single layer of cells that are typically about as tall as they are wide, resembling a cube shape

glands

Secretary cuboidal cells usually function in tubes or clusters of secretary cells

exocrine

Release secretion through duct

Endocrine

Release their secretion directly by diffusion into the bloodstream

simple columnar epithelium

Found lining the inner surface of the stomach, intestines, and some areas of the respiratory and reproductive tracts

goblet cells

Open Spaces singing among cells

Pseudostratified Epithelium

Typical of that which lines the trachea or windpipe

stratified transitional epithelium

Typically found in body areas subjected to stress and must be able to stretch

connective tissue

Most abundant and widely distributed tissue in the body

Loose fibrous connective tissue

Most widely distributed of all connective tissue types. It is the glue that helps keep the organs of the body together.

Aeriolar Tissue

Consist of webs of fibers and a variety of cells embedded in a loose matrix of soft, sticky gel

Collagen

A strong but flexible, fibrous protein

Elastin

Stretchy proteins that make up collagen

Elastic fibers

Helped tissues returned to their original length after having been stretched

Fascia

Primarily composed of aerial tissue and help helps behind the skin, muscle, muscles, bones, and other organs of the body together

Adipose tissue

Also called fat tissue and it stores lipids

Reticular tissue

Another type of fibers connective tissue that has thin, delicate webs of collagen fibers

Dense fibrous connective tissue

Consist of mainly thick bundles of strong collagen

Bone

Hard because it has dense packaging of collagen, bundles, and crusted with mineral crystals containing calcium

Osteons

Also called Haversian systems which compact bone is made up of

Chondrocytes

Located in many tiny spaces distributed throughout the matrix making tissue look like Swiss cheese

Hyaline cartilage

Has only a moderate amount of collagen in its gel matrix, giving it a Transolution, glass like appearance, means glassy

Fibrocartilage

The strongest and most durable type of cartilage

Elastic cartilage

Contains few collagen fibers but large numbers of very fine elastic fibers that give the matrix material a high degree of flexibility

Hematopoietic tissue

The blood light connective tissue found in the red marrow cavities of bones and in organs, such as the spleen, tonsils, and lymph nodes

Skeletal muscle

Striated muscle called voluntary because wield control of this kind of muscle contractions is possible

Cardiac muscle

Forms the walls of the heart, and the regular, but involuntary contractions of cardiac muscle produce the heartbeat

Smooth muscle

Said to be involuntary because it is not under conscious or willful control

Nervous tissue

Controls body functions in coordinates rapid communication between body structures

Neurons

Impulse conducting units of the system

Glia

Specialized connect, connecting and support supporting cells

Cell body

All neurons are characterized by this and it has two types of processes

Axon

One of the processes and it transmits a nerve impulse away from the cell body

Dendrites

Another one of the processes which carry impulses toward the cell body

Regeneration

Growth of new tissue

Scar

A dense fibrous mass

Keloid

Un unusually thick scar that develops in the lower layer of the skin
