| simple squamous epithelium (found & function) | lung;
diffusion |
| simple cuboidal epithelium (found & function) | kidney;
secretion and absorption |
| simple columnar epithelium (found & function) | digestive tract, stomach,;
absorption secretion of mucus |
| pseudostratified columnar epithelium with cilia (found & function) | male sperm carrying ducts, trachea, respiratory tracts;
secretion, propels mucus using cilia |
| stratified squamous epithelium (found & function) | Keritonized- SKIN
nonkeritonized- moist linings esophogus, mouth and vagina;
protects underlying tissues |
| transitional epithelium (found & function) | BLADDER;
stretched and allows to fill with urine |
| loose AREOLAR CT (found & function) | mucus membranes, surrounds capillaries, under epithelia of body widely distributed;
wraps and cushions organs, hold and conveys tissue fluids |
| adipose tissue (found & function) | under skin around kidneys and eyeballs, within abdomen, in breasts;
reserve food fuel, insulates against heat loss |
| dense regular CT (found & function) | (light yellow, looks almost like skeletal) tendons, most ligaments;
attaches muscle to bone or to muscle, attaches bone to bone |
| dense irregular CT (found & function) | dermis of the skin;
able to withstand tension exerted in many directions, structural strength |
| reticular CT (found & function) | lymphoid organs (lymph nodes);
soft internal skeleton that supports other cell types (WBC's, macrophages, mast cells) |
| Hyaline (found & function) | (Purple) forms the embryonic skeleton, forms costal cartilages in ribs, nose and trachea;
supports and reinforces, cushioning properties |
| Elastic cartilage (found & function) | (deep concentrated blue and pink) external ear;
maintains shape of structure, allows flexibility |
| fibrocaritlage (found & function) | intervertebral discs;
tensile strength, absorbs shock |
| bone (found & function) | bones;
supports an protects, levers for muscles, marrow for blood cell formation |
| blood (found & function) | blood vessels;
transport of nutrients, respiratory gases |
| skeletal tissue (found & function) | skeletal muscles attached to bones, occasionally skin;
VOLUNTARY MOVEMENT, locomotion, facial expressons |
| cardiac tissue (found & function) | (dark purple) walls of the heart;
contracts, propels blood into circulation, INVOLUNTARY |
| smooth tissue (found & function) | walls of hallow organs;
propels substances along passageways, INVOLUNTARY |
| nervous tissue (found & function) | brain, spinal cord, nerves;
transmit electrical signals from sensory receptors, |
| 5 characteristics of epithelial tissue | 1. composed entirely of cells, very little ECM
2. cells are jointed tightly together into one or more sheets
3. have a basement membrane
4. avascular
5. can regenerate by mitosis |
| epithelial tissue can be classified by: | cell shape & cell arrangement |
| definition of Tissue: | an organization of cells similar in structure and perform a common or related function, |
| the most durable tissue type: | connective |
| most widespread tissue in the body: | connective |
| 5 major FUNCTIONS of epithelium: | protection (ie skin),
absorption (ie cells lining digestive tract),
filtration (ie kidneys),
secretion (ie glands),
sensory reception (free endings of sensory neurons) |
| how does stratified differ from simple epithelia? | Stratified have more layers for protection; simple allow materials to move across them and are less protective |
| difference between exocrine and endocrine glands? | Endocrine are ductless glands with secrete hormones that are liberated into the bloodstream. Exocrine have ducts which secrete their various types of secretion to the surface of the body |
| lining of the esophagus | stratified squamous |
| lining of the stomach | simple columnar |
| alveolar sacs of lungs | simple squamous |
| tubules of the kidney | simple cuboidal |
| epidermis of the skin | stratified squamous |
| lining of the bladder | transitional |
| forms the thin serous membranes | simple squamous |
| 4 Types of CT | connective Tissue Proper,
cartilage,
blood,
bone |
| CT can be classified by: | no free surface,
varying degrees of vascularity,
widely separated by lots of non living ECM |
| ECM types of fibers | collagen,
elastic,
reticular |
| functions performed by CT | protection, support, binding together other tissues |
| 2 characteristics developed in neurons: | irritability & conductivity |
| how are neurons SIMILAR to other cells | contain nucleus and usual organelles |
| how are neurons DIFFERENT from other cells | cytoplasm is drawn out into long processes |
