TISSUES

MUSCLES

The skeletal muscle are the muscles that when you touch your skin you can feel and move. they are muscles that are attached to your bones, to help you move and protect your bones.(4)

The smooth muscle can be found in the wall of hollow organs, like the stomach. Its there to protect the organs but isn’t as colorful as the skeletal muscles, they blend in with the walls of the organs. (4)

The cardiac muscle is the muscle in the walls of the heart, its a lot like the skeletal muscle and the smooth muscle because it can be involuntary like the skeletal, which means that it is controlled by the nervous system, but if it didn’t have a nervous system it would also be voluntary like the smooth muscle, which controls itself. (4)

NERVOUS

Nervous tissue is made of neurons and neurological cells, that transmit electrical signals. (4)

Soma: The part of the cell that contains the nucleus. (4)

Dendrites: extending from the soma, receives information and moves it toward the soma. (4)

Axon (nerve fiber): Transports information away from the soma. (4)

Simple Squamous- Physically flat, scalelike cells. Substances can easily diffuse through this tissue. The microscopic air sacs in the lungs are made of this tissue. (4)

Stratified Squamous- Keratinized is made up of multiple layers of cells with flattened squamous cells at the outer surface. Possesses keratin which contributes to its protective qualities (ex. Skin) (4)

Transitional- stratified; found in body areas that are subjected to stress and tension changes (ex. Urinary bladder) As tension increases, the cell will change from a cuboidal shape to squamous. This transition protects the distensible structures from tearing. (4)

Stratified Columnar- multiple layers of columnar cells, although only the closest cells to the surface look columnar in shape. Rare in the human body, found only in the male urethra and in the mucous layer near the anus. (4)

EPETHELIAL

Pseudostratified- found in the lining of air passageways in the respiratory system and in areas of the male reproductive system. Only a single layer of irregularly shaped columnar cells touches the basement membrane, and because of the differing heights, many are not tall enough to reach the upper surface of the epithelial sheet. (4)

Simple Cuboidal- made of one layer of cuboidal cells resting on a basement membrane and makes up glands and their ducts (ex. Kidney) (4)

Stratified Cuboidal- Protective function; at least two rows of low cuboidal cells are randomly arranged at the basement membrane. Located in sweat glands ducts, pharynx and parts of the epiglottis. (4)

Glandular- specialized for secretory activity in the glands. Able to function unicellular or in clusters or specialized follicles like multicellular glands. (4)

Epethelial

Fiber types include:•Collagenous fibers: strong and flexible fibers that appear as wavy bundles in tissue sections.•Reticular fibers: thin collagen fibers coated with a glycoprotein. They tend to branch extensively forming delicate networks.•Elastic fibers: consist of the protein elastin, which allows for stretching and recoiling. (5)

Areolar connective tissue consists of a loose arrangement of fibers. It contains all of the cell types mentioned, as well as all three fiber types. Areolar also has an abundance of ground substance, which appears white in tissue preparations.(5)

Adipose tissue consists of adipocytes, which store fat droplets. The nucleus of the adipocyte is located adjacent to the plasma membrane.(5)
