| Question | Answer |
|---|---|
| define ectoderm | the tissue that develops into nervous tissue |
| define mesoderm | the tissue which gives rise to all connective tissues and most muscle tissues |
| define endoderm | the primal germ layer theat gives rise to the gastrointestinal tract, urinary bladder, urethra, and respirtory tract |
| 3 functions of cell junctions | for seals between cells, anchor cells to one another or to extracellular material, or to provide channels that allow ions and molecules to pass from cell to cell |
| desmosomes | use the plaque and transmembrane glycoproteins that are in them to extend into the intracellular space between adjacent cell membranes and attatch cells to one another. |
| gap junctions | allow communication |
| apical surface of an epithelial cell | the body surface, a body cavity, the luman of an internal organ, or a tubular duct that recieves secretions |
| avascular | no blood supply |
| epithelial tissue endures stress: | becayse a high rate of cell division allows epithelial tissue to renew and repair itself |
| covering and linign epithelial tissues are classified by: | the arrangment of cells into layers and the shapes of the cells |
| a pap smear examines: | the nonkeratinized stratified squamous epithelium in the cervix and vagina |
| merocrine glands function: | the secretion is synthesized on ribosomes attatched to rouigh and are processed, sorted, and packaged byt he golgi complex and released front the cell in the secretory vesicles via exocytosis. |
| holocrine glands function: | accumulating a secretory product in their cytosol. as the secretory cell matures, it becomes the secretory product. the sloughed off cell is replaced by a new cell. |
| function of transitional epithelium: | lines urinary bladder and allows you to hold various amounts of liquid without rupturing. |
| function of stratified columnar epithelium: | protection |
| function of pseudostratified columnar epithelium: | secretion and movement of mucus by ciliary action |
| function of stratified cuboidal epithelium: | protection and found in adult sweat glands |
| function of stratified squamous epithelium: | protection(several layers) |
| keratinized | epidermis/ lets no fluids out |
| nonkeratinized | mouth, esophagus, vagina, tongue/ lines wet surfaces |
| function of ciliated simple columnar epithelium: | cilia beat in unison and move mucus and foreign objects toward the throat to be coughed out |
| function of nonciliated simple columnar epithelium: | secretion and absorption/lines gi tract |
| goblet cells | secrete mucus that lubricates the linings of the degestive, respirtory, reproductive, and urinary tract |
| function of simple cuboidal epithelium: | secretion and absorption/found covering ovaries, in kidneys and eyes, and makes up secretion portion of some glands |
| function of simple squamous epithelium: | filtration |
| histology | study of tissues |
| pathologist | physician who studies cells and tissues to hlep make accurate diagnoses; examine tissues for changes that might indicate disease |
| vascular | connective tissue-blood supply except tendons |
| new ending names of mature connective tissue cells | cytes |
| loose connective | loose fibers(more cells) |
| dense connective | dense fibers(less cells) |
| post surgical complications of liposuction: | fat clots, infection, fluid depletion, injury to internal structures, severe pain |
| dense regular connective tissue | provides great strength through parallel bundles of collagenic fibers;found in tendons |
| adipose connective tissue | acts as a storage depot for fat |
| dense irregular connective tissue | composes the dermis of the skin |
| osseous tissue | forms the bony skeleton |
| areolar connective tissue | composes the basement membrane and packages organs; includes a gel-like matrix with all categories of fibers and many cells types |
| hyaline cartilage | forms the embryonic skeleton and the surfaces of bones at the joints; reinforces the trachea |
| adipose connective tissue | provides insulation for the body |
| hyaline cartilage | structurally amorphous matrix, heavily invaded with fibers; appears glassy and smooth |
| osseous tissue | contains cells arranged concentrically around a nutrient canal; matrix is hard due to calcium salts |
| reticular connective tissue | forms the stroma or internal skeleton of lymph nodes, the spleen, and other lymphoid organs |
| cartilage | provides smooth surfaces for movement at joints, as well as flexibility and support |
| compact bone | support, protection, storage |
| blood | red blood cells transport O2 and CO2 to the body |
| function of skeletal muscle tissue | motion, posture, heat production |
| function of cardiac muscle tissue | pumps blood to all parts of the body |
| function of smooth muscle tissue | motion |
| function of nervous tissue(neurons) | exhibits sensitivity to various types of stimuli |
| epithelium tissue | forms mucous, serous, and epidermal membranes |
| muscle tissue | allows for organ movements within the body |
| nervous tissue | transmits electrochemical impulses |
| connective tissue | supports body organs |
| epithelium tissue | cells of this tissue may absorb and/or secrete substances |
| nervous tissue | basis of the major controlling system of the body |
| muscle tissue | the cells of this tissue shorten to exert force |
| epithelium tissue | forms hormones |
| connective tissue | packages and protects body organs |
| connective tissue | characterized by having large amounts of nonliving matrix |
| muscle tissue | allows you to smile, swim, ski, and shoot an arrow |
| connective tissue | most widely distributed tissue type in the body |
| nervous tissue | forms the brain and spinal cord |
| voluntarily controlled | skeletal muscle tissue |
| involuntarily controlled | cardiac and smooth muscle tissue |
| banded appearance | skeletal and cardiac muscle tissue |
| single nucleus in each cell | cardiac an dsmooth muscle tissue |
| multinucleate | skeletal muscle tissue |
| found attached to bones | skeletal muscle tissue |
| allows you to direct your eyeballs | skeletal muscle tissue |
| found in the walls of the stomach, uterus, and arteries | smooth muscle tissue |
| contains spindle shaped cells | smooth muscle tissue |
| contains cylindrical cells with branching ends | cardiac muscle tissue |
| contains long, non-branching cylindrical cells | skeletal muscle tissue |
| displays intercalated disks | cardiac muscle tissue |
| concerned with locomotion of the body as a whole | skeletal muscle tissue |
| changes the internal volume of an organ as it contracts | cardiac and smooth muscle tissue |
| tissue of the circulatory pump | cardiac muscle tissue |
| 2 types of tissue that make up the mucous membrane | epithelium and connective |
| viscera that are covered by the peritoneum | abdominal cavity |
| axon | simple, thin, cylindrical process that may be very long. the output portion of a neuron, conducting nerve impulses toward another neuron or to some other tisssue |
| dendrite | tapering, highly branched, and usually short processes. the recieving or input portion of the neuron |
| cell body | contains the nucleus and other organelles |
| atrophy | decrease in size of cells |
