what is the structure and function of adipose tissue? |
|
Definition
fat tissue. Look like rings because the nucleus in on the outer rim. Function is provide and reserve food fuel; insulates against heat loss; supports and protects organs. |

Term
Give description of Epithila |
|
Definition
Primary tissue that covers the body's surface, lines it's internal cavities and forms glands. |

Term
Information about Cartilage |
|
Definition
Cartilage stands up to both tension and compression has qualities intermediate between dense connective tissue and bone. Cartilage lacks nerve fibers and is avascular. It's up to 80% water and receives nutrients by diffusion from blood vessels located in the connective tissue membrane. |
|
|
Term
What constitutes tissues? |
|
Definition
groups of cells that are similar in structure and perform a common or related function. |
|
|
Term
Simple Squamous Epithelium: function? structure? and location? |
|
Definition
single layered flattened cells. function: allows passage of materials by diffusion and filteration, in sites where protection is not important. Location: Kidney glomeruli; air sacs of lung; lining of heart; blood vessels and lymphatic vessels. |
|
|
Term
Simple Cubodial Epithelium: Function? Structure? Location? |
|
Definition
Structure: single layer cube like. Function: secretion and absorption. Location:Kidney tublues; ducts and secretory of small glands; ovary surface. |
|
|
Term
Simple Columnar Epithelium: Structure? Function? Location? |
|
Definition
Single layer of tall cell with round to oval nuclei. Function: Absorption; secretion of mucus enzymes and other substances; ciliated type propels mucus by ciliary action. Location: digestive tract to anal canal; gall bladder; and excretory dut of some glands; ciliated variety lines the small bronchi; uterine tubes and some regions of the uterus. |
|
|
Term
Pseudostratified Columnar Epithelium: structure? function? location? |
|
Definition
Single layer of differing heights some not reaching the free surfaces. Function: Secretion of mucus; porpulsion of mucus by ciliary action. Location: male sperm carrying ducts and ducts of large glands; ciliated variety lines the trachea; most of the upper respiratory tract. |
|
|
Term
stratified squamous epithelium: Structure? Function? Location? |
|
Definition
Several layers, basal cells are cubodial or columnar, surfaces are squamous (Surface cells are full of keratin and are dead). Function: protects underlying tissues. Location: moist linings of the esophagus, mouth and vagina, epidermis and dry membrane. |
|
|
Term
Transitional Epithelium: Structure? Function? Location? |
|
Definition
Resembles both stratified squamous and stratified cubodial(basal cells cubodial or columnar like, surface squamouslike). Function: stretches and permits distension of urinary organ by contained urine. Location: Line uterus, urinary bladder and part of the urethra. |
|
|
Term
Hyaline Cartilage: structure? function? location? |
|
Definition
Amorphous and glassy but firm matrix. Function: Supports and reinforces; has cushioning properties; resists compressive stress. Location: forms most of the embryonic skeleton, covers the ends of most bones in joint cavities, forms costal cartilages of the ribs; cartilages of the nose; trachea, and larynx. |
|
|
Term
Elastic Cartilage: Structure? Function? Location? |
|
Definition
Similar to Hyaline cartilage but more elastic fibers in the matrix. Function: Maintains the shape of a structure while allowing great flexibility. Location: External ear; epiglottis. |
|
|
Term
Fibrocartilage: Structure? Function? Location? |
|
Definition
Matrix similar but less firm then the hyaline cartilage; thick collagen fibers predominate. Function: Tensile strength with the ability to absorb compressive shock. Location: Intervertebral discs; pubic symphysis; discs of knee and joint. |
|
|
Term
|
Definition
High calcified matrix many collagen fibers; very well vascularized. Function: supports and protects; provides levers for the muscles to act on; store minerals, calcium, and fat, stores marrow inside for blood cell formation. |
