what is epithelial tissue? | forms sheets that cover the body and many of its parts |
what are examples of connective tissue? | blood, cartilage, bone, white fat, and areolar-most abundant in the body |
what is collagen ? | is a protein that forms microscopic twisted ropes within the matrix of many tissues- gives tissue flexibility |
simple squamous epithelium is a... | single layer of flattened cells that have irregular shape cells when viewed from the surface |
stratified squamous epithelium is... | consists of several layers of closely packed cells, an arrangement that makes this tissue especially adept to protection |
simple cuboidal epithelium is... | is a single layer of cells that are typically about as tall as they are wide-thus resembling a cube shape |
columnar epithelium can be... | found lining the inner surface of the stomach, intestines and some areas of the respiratory and reproductive tract |
stratified transitional epithelium is... | found in body areas subjected to stress and must be able to stretch (lining of bladder) |
what is the most unusual connective tissue? | blood |
areolar | glue that holds tissue together |
adipose (fat) | lipid storage is the primary function |
fibrous | bundles of strong collagen fibers |
bone | matrix is calcified, function is support and protection |
cartilage | matrix is consistency of gristle like gel. chondrocyte is the cell type |
blood | transportation and protection |
connective tissue that serves as protection, insulation, nutrient reserve and heat | Adipose (fat) |
skeletal muscle tissue | attaches to bones- also called striated or voluntary, control is voluntary. |
cardiac muscle tissue | also called striated or involuntary / composes the heart wall. |
smooth muscle tissue | also called nonstriated(visceral) or involuntary.no cross striations, found in blood vessels |
nervous tissue | controls body functions and coordinates rapid communication between body structures |
what is the function of nervous tissue? | rapid communication between body structures and control body function |
what are the 2 kinds of nervous tissue? | neurons (conduction cells) and Gila (special connecting and supporting cells) |
what are the 4 main tissue types? | Epithelial, connective, muscle and nervous |
keloid | keloids are thick scars that form in the lower layer of the skin in predisposed individuals |
