front 3 connective | back 3 joins other tissue types together |
front 4 muscle | back 4 contracts and relaxes involved in movement |
front 5 nerve | back 5 generates and conducts nerve impulses |
front 6 epithelium | back 6 a layer of closely packed cells that lines an external or internal surface has no blood supply; it is nourished by diffusion from the blood supply of he connective tissue adjacent to it chief function is protection but also secretion, absorption secretion, excretion, lubrication, and even sensory perception |
front 7 TYPES OF EPITHELIAL | back 7 simple epithelium stratified epithelium |
front 8 simple epithelium | back 8 single layer squamous cells that are flat in shape: intestinal serosa cuboidal (cells are cubical): thyroid follicles columnar (cells are long and narrow): intestinal mucosa |
front 9 simple squamous epithelium | back 9 composed of cells shaped like tiles thin and flat with round or oval nuclei. specialized for exchange of materials. lines inside walls of blood vessels body cavity and the bowman capsules of the kidney |
front 10 simple cuboidal epithelium | back 10 appear square in side view and have a secretory or absorptive function. found in areas such as kidney tubules and thyroid follicles |
front 11 simple columnar epithelium | back 11 composed of cells that are significantly taller than they are wide appear as a row of rectangles standing on end, with the nuclei frequently all at the same level, usually in the lower part of the cell may be ciliated golblet cells specialized for the secretion of mucus found where a need for secretion or absorption exists and the wear and tear is considerable. lines a large part of respiratory and digestive tracts and oviducts |
front 12 stratified epithelium | back 12 composed of two or more layers of epithelial cells. it is not adapted for absorption or secretion but for areas subject to extensive wear and tear. forms outer layer of skin mouth esophagus, anus, vagina, |
front 13 pseudo stratified columnar epithelium | back 13 simple epithelium with all the cells resting on a basement membrane cells have the appearance of a stratified epithelium because they are not all the same height and their nuclei are located at different levels. lines trachea bronchi male urethra |
front 14 stratified epithelium | back 14 2 or more layers thick human skin |
front 15 types of connective | back 15 adipose cartilage bone blood dermis |
front 16 loose connective tissue (areolar, reticular, adipose) | back 16 serves as packing material filling spaces between body parts |
front 17 dense connective tissue (dermis fasciae, ligaments, and tendons) | back 17 perform major supportive function |
front 18 blood | back 18 derived from a form of loose connective tissue and cartilage and bone |
front 19 fibers | back 19 collagenous elastic reticular |
front 20 collagenous fibers | back 20 appear as thick wavy bundles of finer fibrils. They are flexible but very strong and resistant to stretching |
front 21 elastic fibers | back 21 thin branching threads that usually appear straight |
front 22 reticular fibers | back 22 consist of bundles of small inelastic fibrils. smaller than collagenous fibers and they branch and reunite extensively |
front 23 adipose connective tissue | back 23 fat |
front 24 catilage | back 24 most common form is hyaline cartilage found on the ends of long bones and in the nose trachea matrix is firm and flexible lacunae- cavities containing one cell |
front 25 bone | back 25 most specialized bone matrix secreted by bone forming ells called osteocytes and is composed of crystals of calcium phosphate with collagenous fibers between the crystals to reduce the brittleness of the bone compact bone and spongy bone |
front 26 periosteum | back 26 thin layer of dense connective tissue that covers bone |
front 27 enthrocytes | back 27 red blood cells |
front 28 leukocytes | back 28 white blood cells |
front 29 granular leukocytes | back 29 neutrophils eosinophils basophils |
front 30 neutrophils | back 30 finely granular cytoplasm and a polymorphic nucleus with from three to five lobes MOST ACTIVE PHAGOCYTE |
front 31 eosinophils | back 31 bilobed nucleus which amy be partly obscured by bright red spherical granules in the cytoplasm |
front 32 basopils | back 32 have an elongate curved nucleus which may be partly obscured by blue granules in the cytoplasm |
front 33 agranular leukocytes | back 33 lymphocyetes monocytes |
front 34 lymphocytes | back 34 slightly larger than enthrocytes have nucleus which is only slightly smaller than the cell itself. cytoplasm forms thin clear cresent around the cells nucleus |
front 35 monocytes | back 35 larger and have a smaller nucleus more cytoplasm visible MOST ACTIVE PHAGOCYTE |
front 36 blood platelets | back 36 disk shaped fragille clot promoting bodies found only in mammal blood |
front 37 smooth muscle | back 37 simplist digestive tract uterus |
front 38 skeletal muscle | back 38 long cylindrical blunt ends have blood vessels and nerves tongue |
front 39 cardiac muscle | back 39 heart have intercalated discs which mark the boundaries between the ends of adjacent cells |
front 40 nerve tissue | back 40 nerve cells called neurons |
front 41 neuron | back 41 carry impulses into the nerve cell called dendrites those that carry impulses away are called axons |
front 42 in what ways does epithelial tissue differ from other tissue types | back 42 it has specialized types and is used for absorption, secretion, excretion, lubrication, and sensory perception |
front 43 in what important way does connective tissue differ from other tissue types | back 43 connects tissues together provides structure and support and function in metabolism. it is largely composed of extracellular matrix |
front 44 compare and contrast cartilage and bone | back 44 bone is specialized in structural support cart is found at the end of bones in the nose trachea providing cushioning support both are connective tissues |
front 45 compare and contrast the structures of the three muscle types | back 45 skeletal: made of fibers bundles and found in connective muscle tissues; richly supplied by blood vessels and nerves smoothL found in digestive tract uterus; sustained areas that contract used for involuntary action cardiac: found in heart; involuntary slow rhythmic contractions |
front 46 parts of neuron | back 46 neuron consists of a cell body dendrites axons and mycelian sheath (supportive cell membrane) |
front 47 how does a tissue differ from an organ | back 47 group of cells specialized for a particular function is a tissue while an organ is a group of tissues |
front 48 all tissue types in small intestine | back 48 mucosa, submucosa, smooth muscle, goblet cells |
front 49 tissues found in c.s of the small intestine from the outside to the lumen | back 49 subucosa, smooth tissue, serosa, mucosa, longitudinal muscle, lumen |
