Tissues
| Question | Answer |
|---|---|
| 4 primary types of tissue | epithelial, connective, muscle, nervous |
| study of tissues | histology |
| 6 functins of epithelial tissue | protection, secretion, excretion, filtration, absorption, sensory |
| cavity within a tubular structure | lumen |
| means "having nerves" | innervated |
| vasculature | blood vessels |
| 3 types of cell junctions | tight junctions, desmosomes, gap junctions |
| junctions in urinary bladder and digestive tract | tight junctions |
| junction in skin, heart, uterus | desmosome |
| junction in intestines, heart, smooth muscle | gap junctions |
| one layer | simple |
| multiple layers | stratified |
| foundation of hte epithelial cell | basement membrane |
| 6 subtypes of epithelial tissue | squamous, cuboidal, columnar, pseudostratified, transitional, glandular |
| flat, thin,plate-like epithelial cells | squamous |
| epithelium in the middle | mesothelium |
| epithelium within | endothelium |
| lines the mouth, esophagus | stratified squamous |
| lines the vagina and rectum | stratified squamous |
| cube shaped | cuboidal epithelium |
| covers ovary surface and kidney tubules | simple cuboidal |
| pleura, pericardium and peritoneum | mesothelium |
| blood vessels, lymphatic vessel | endothelium |
| vagina, rectum | squamous (stratified) |
| forms active part of glands & kidney tubules | cuboidal (simple) |
| covers ovary surface | cuboidal (simple) |
| in ducts of sweat glands, salivary glands, mammary glands | cuboidal (stratified) |
| lines digestive tract from stomach to rectum | columnar |
| have cilia and goblet cells | columnar |
| line bronchi, uterine tubes and uterus | columnar (ciliated) |
| looks layered but is not | pseudostratified |
| line bladder | transitional |
| line uterus | transitional |
| very elastic | transitional |
| highly specialized epithelial cells | glandular |
| excrete and secrete | glandular |
| substances that leave the body | excretions |
| substances that stay within the body | secretions |
| Endo | within |
| Exo | out; away from |
| -crine | to secrete |
| glands without ducts or tubules | endocrine glands |
| glands with ducts | exocrine |
| nonliving extracellular matrix | connective tissue |
| bone | connective tissue |
| is bone well vascularized | yes |
| 3 components of connective tissue | cells, fibers, matrix (ground substance) |
| 5 functions of connective tissue | connect & support, protect, insulate, transports fluids, stores energy |
| 3 connective fibers | collagen, elastic, reticular |
| fiber that is white fiber, very strong, in tendons & ligaments | collagen fibers |
| fiber that is long thin, yellow, stretchable, in vocal cords, lungs, skin , blood vessels | elastic fibers |
| fiber that is not thick, is delicate and forms networks | reticular fibers |
| adipose tissue is what type of tissue | connective tissue |
| adipose means | fat |
| what type of adipose is a source of heat production | brown |
| when the spaces in the loose connective tissue fill with excessive fluid | edema |
| sough connective tissue in joints | cartilage |
| does cartilage have nerves | no |
| cartilage at the end of bones in joints and rings of trachea | hyaline |
| cartilage in the epiglottis, larynx, pinna | elastic |
| cartilage in the vertebrae, between bones of pelvis, in knee | fibrocartilage |
| controlled through conscious effort | voluntary |
| contraction cannot be consciously controlled | involuntary |
| heart is a _____ muscle | cardiac, involuntary |
| 3 types of muscle | skeletal, smooth, cardiac |
| breathing is | involuntary |
| running is | voluntary |
| muscle in the wall of hollow organs | smooth |
| heart muscle | myocardium |
| conducts electrical impulses | nervous tissue |
| in brain, spinal cord and nerves | nervous tissue |
| longest cells in body, conduct impulses | neurons |
| supporting nervous cells, do not conduct | glial |
| short extension of nerve cell, receives impulse | dendrite |
| long extension, sends impulse | axon |
