tissues, membranes, and the integumentary system
| Question | Answer |
|---|---|
| adipose | a specialized connective tissue composed mostly of fat beneath the skin insulates and protects the body |
| areolar tissue | most widely distributed connective tissue, functions as packing tissue and can soak up extra fluid(edema) |
| bone | osseous tissue, protects and supports organs and creates central canals for nerves and blood vessels |
| connective tissue | most abundant tissue, connects, protects, supports, and insulates other body tissues |
| dense connective tissue | made up of mainly collagen fibres and fibroblasts forms tendons and ligaments |
| desiccation | drying out of body tissues especially between vertebrae |
| elastic cartilage | elastic moveable cartilage found in structures such as ear lobe, and nose |
| endocrine glands | ductless glands that diffuse into blood vessels |
| exocrine glands | contain ducts through which secretions empty to an epithelial surface ex:sweat, oil, digestive glands |
| epithelial tissue | lining, covering, and glandular tissue of the body covers all free body surfaces functions to absorb, secrete, filter, and lightly protect |
| extracellular matrix | non-living materials surrounding living cells that keep most from being packed tightly together |
| fibrocartilage | fibrous cartilage highly compressible between vertebrae |
| hyaline cartilage | has abundant collagen fibers hidden by rubbery matrix with a glassy appearance Ex:cartilage between ribs |
| glands | any organs that create fluid to be distributed throughout the body |
| muscle tissue | skeletal, cardiac, and smooth specialized to contract or shorten to produce movement |
| nervous tissue | neuron cells with functions of irritability and conductivity |
| pseudostratified columnar epithelium | single layer of columnar epithelium with varying heights making it appear stratified |
| reticular connective tissue | delicate network of interwoven reticular fibres forming the stroma of inner organs |
| secretion | release of a substance |
| hormone | chemical messengers produced by specialized endocrine glands or organs that travel through the bloodstream to bind with specific cellular receptors and regulate bodily functions |
| simple columnar epithelium | one layer of tall cells fit close together often containing goblet cells producing mucus lines the digestive tract |
| simple cuboidal epithelium | one layer of cuboidal cells resting on a basement membrane common in glands and ducts, salivary glands, pancreas, and kidney tubules |
| simple squamous epithelium | one layer of thin squamous cells resting on a basement membrane forms membranes for filtration and diffusion, air sacs of lungs, capillary walls, and serous membranes |
| Stratified squamous epithelium | most common stratified epithelium, consists of many layers, cells at free edge are squamous cells close to basement cuboidal or columnar found in surface of skin, mouth, and esophagus |
| stratified cuboidal epithelium | just 2 layers of cells with at least surface being cuboidal |
| stratified columnar epithelium | only 2 layers columnar cells on surface, basal cells vary in size and shape found mainly in ducts of large glands |
| Transitional epithelium | modified stratified squamous the lines the urinary system allowing stretch, basal cells are cuboidal or columnar and surface vary cells flatten when stretched by fluid |
| chondrocytes | cartilage cells |
| lacunae | a small, microscopic cavity, pit, or empty space within biological and anatomical tissues that houses and protects resident cells |
| osteocytes | bone cells |
| collagen | the most abundant protein in your body, acting like the natural "glue" or scaffolding that holds your body together, white, forms ligaments and tendons |
| Elastin/ic fibres | yellow , a key fibrous protein in the extracellular matrix that gives connective tissues the ability to stretch and snap back to their original shape, ex:ears, nostrils |
| Reticular fibres | mesh for inside structure of some soft organs ex:spleen |
| adipocytes | fat cells |
| blood plasma | non living fluid matrix surrounding blood cells making it a connective tissue |
| interceltaed discs | found in cardiac muscle tissue;junctions that allow ions to pass freely from cell to cell |
| striations | a long, thin line, groove, scratch, or strip of color that is usually part of a parallel series on a surface;found in skeletal and cardiac muscle tissue |
| regeneration | damaged tissue fixed by the same cells maintaining the anatomy and physiology |
| fibrosis | tissue repair by dense connective tissue;does not maintain anatomy or physiology;scar tissue |
