4 major types of Tissue? Epithial, Connective, Muscle and Nerve
What Epithelial Tissues do? cover all the body surfaces inside and out and are the major tissue of glands.
What is a basement membrane? located in the non living underside of the epithelium which heals rapidly and provides a protective barrier for the body.
Epithelial is responsible for...? Secretion, Absorption, Excretion and Sensory reception.
What are Exocrine Glands? secrete products into ducts opeining onto an internal or external surface.
How many types of Exocrine glands? 3
What are Merocrine glands? release fluid through the cell membrane and do not lose any portion of the cell during secretion.
What are examples of Merocrine glands? Salavary, Pancreatic and some sweat glands
What are most glands? Merocrine glands
What are the 2 catagories of Merocrine glands? Serous and mucus
What do serous glands do? secret serous fluid which is water and has high enzyme concentration.
Example of serous gland...? Digestive tract.
What do mucous glands do? secretes thick layer of mucous which is rich in glycoprotein called mucin.
What is mucin? glycoprotein
Example of mucous glands...? Digestive tract and respirtory tubes.
What are Apocrine Glands? Lose small portion of cell during secretion.
Examples of Apocrine Glands...? Mammory and some sweat glands.
What are Holocrine glands? release entire cells filled with secretory products.
Examples of Holocrine glands...? sebacous glands ( oil )
what are endocrine glands? secrete products into tissue, fluid or blood.
What is an example of endocrine glands? hormones
What are the most abundant tissue? connective
what are connective tissues function? binds structures together, provides support, serves as frame work, fills spaces, stores fat, produces blood cells, protects against infection and helps repair tissue damage.
What are resident cells? present in stable numbers in connective tissue
What are fibroblasts? secretes protiens into the matrix to produce fibers
what is the most common resident cell? fibroblasts
what fibers are produced by fibroblasts? collageneous and elastic
what are collagenous fibers? thick thread like componets of collagen that make up tendons.
what are other names for collagenous fibers? dense connective tissue or white fibers.
what are elastic fibers? composed of microfibers and a protein called elastin.
where are elastic fibers found? vocal cords
what is another name for elastic fibers? yellow fibers
what are macrophages? responsible for phagocytosis which allows them to clear the body of froeign particles and change shape
what is phagocytosis? ability to change shape and engulf an object.
what are mast cells? widely distributed in connective tissue and are located near blood vessels.
What do Mast Cells contain? Heparin- which prevents blood clotting and histamine.
what are Wandering Cells? appear temporarily due to infection.
what are examples of wandering cells? white blood cells
What are loose connective tisses? forms thin delicate membranes which contain collagin and elastin fibers.
what do loose connective tissues do? bind skin to underlying organs, fill spaces between muscle, lay beneath epithelium, provide nurishment for epithelial cells.
what serves as a protective cushion for joints and organs? adipose tissue
what is adipose tissue made of? fat
what is adipose tissue? specialized form of tissue found beneath the skin and in between muscles.
what is a heat insulator and storer of fat? adipose tissue.

what binds body parts together? fibrous connective tissue
what is slow healing and has poor blood supply? fibrous connective tissue.
what is cartilage? rigid connective tissue which supports protects and provides framework.
what are cartilage cells called? chondroytes
what occupy small chambers called lacunae? chondroytes.
what is a perichondrium? a fiberous connective tissue which encloses the cartilage.
what doesnt have a blood supply? cartilage.
what are the 3 types of cartilage? Hyaline, Elastic and fibrocartilage.
what is hyaline cartilage? has fine cartilage fibers and is found in the soft part of the nose.
what is the most common type of cartilage? Hyaline
what is elastic cartilage? has a dense network of fibers and is more flexible. found in the ear and larynx.
what is fibrocartilage? tough tissue with many collagenous fibers. found between the vertibrae and in the knees and pelvus.
What is bones function? probides internal support, protects vital organs, serves as an attachment for muscles and forms red blood cells.
what is the most rigid connective tissue? bone.
cytes = ? cells
