Unit 3: Tissues
| Question | Answer |
|---|---|
| forms membranes | epithelium |
| allows for movement of limbs and for organ movements within the body | muscle |
| uses electrochemical signals to carry out its functions | nervous |
| supports and reinforces body organs | connective |
| cells of this tissue may absorb and/or secrete substances | epithelium |
| basis of the major controlling system of the body | nervous |
| its cells shorten to exert force | muscle |
| forms endocrine and exocrine glands | epithelium |
| surrounds and cushions body organs | connective tissues |
| characterized by having large amounts of extracelular material | connective |
| allows you to smile, grasp, swim, ski, and throw a ball | muscle |
| widely distributed, found in bones, cartilages, and fat depots | connective |
| forms the brain and spinal cord | nervous |
| protects, absorbs, filtrates, excretes, secretes, sensory reception | epithelium |
| lines the stomach and most of the intestines | simple columnar epithelial |
| A single layer of tall packed cells, aligned like soldiers in a row. | simple columnar epithelial |
| It protects organs from bacteria and keeps them from getting damaged. | simple columnar epithelial |
| lines the inside of the mouth | stratified squamous epithelial |
| groups of cells that are similar in structure and perform a common or related function | tissue |
| Consisting of two or more cell layers stacked one on top of the other, are common in high abrasion areas where protection is important | stratified squamous epithelial |
| It is a lining tissue which provides protection for underlying tissues | stratified squamous epithelial |
| lines much of the respiratory tract | pseudostratified ciliated columnar epithelial |
| single layer of cells, differing in heights All of its cells rest on the basement membrane, but only the tallest reach the free surface of the epithelium. | pseudostratified ciliated columnar epithelial |
| Secrets and absorbs substances | pseudostratified ciliated columnar epithelial |
| endothelium and mesothelium | simple squamous epithelial |
| Single layer of flattened cells with disc- shaped central nuclei and sparse cytoplasm; the simplest of the epithelia | simple squamous epithelial |
| Reduces friction, performs absorption and secretion. | simple squamous epithelial |
| lines the inside of the urinary bladder | transitional epithelial |
| The apical cells vary in appearance, depending on the degree of distension of the organ | transitional epithelial |
| allows a greater volume of urine to flow through a tube-like organ. In the bladder, it allows more urine to be stored. | transitional epithelial |
| protection | stratified squamous epithelial |
| small molecules pass through rapidly | simple columnar epithelial |
| propel sheets of mucus | ciliated epithelium |
| absorption, secretion, or ion transport | simple columnar epithelial |
| stretches | transitional epithelial |
| binding and and support, protection, insulation, transportation | connective |
| attaches bones to bones and muscles to bones | dense fibrous connective tissue |
| Primarily irregularly arranged collagen fibers; some elastic fibers; major cell type is the fibrosis. | irregular dense fibrous connective tissue |
| Able to withstand tension exerted in many directions; provides structural strength. | irregular dense fibrous connective tissue |
| Contains closely packed bundles of collagen fibers running in the same direction, parallel to the direction of the pull | regular dense fibrous connective tissue |
| Forms the tendons, which are cords which attach muscles to bones or to other muscles | regular dense fibrous connective tissue |
| acts as a storage depot for fat | adipose connective tissue |
| Areolar connective tissue modified to store nutrients; a connective tissue consisting chiefly of fat cells | adipose loose connective tissue |
| the dermis of the skin | dense fibrous connective tissue |
| makes up the intervertebral discs | fibrocartilage connective tissue |
| Matrix similar to but less firm than that in hyaline cartilage, thick collagen fibers predominate. | fibrocartilage connective tissue |
| Tensile strength with the ability to absorb compressive shock. | fibrocartilage connective tissue |
| forms the hip bone | bone connective tissue |
| is packed into osteons to create rings of bony matrix that surround central canals containing nerves and blood vessels | bone connective tissue |
| Supports and protects by enclosing Provides levers for the muscles to act on Stores calcium and other minerals and fat Bone marrow is where blood cell synthesis occurs | bone connective tissue |
| provides a flexible framework for the external ear | elastic cartilage connective tissue |
| Nearly identical to the Hyaline Cartilage! Contains large numbers of elastin fibers The matrix Appears glassy | elastic cartilage connective tissue |
| These are found where strength and a lot of flexibility are needed | elastic cartilage connective tissue |
| matrix hard owing to calcium salts; provides levers for muscles to act on | bone connective tissue |
| insulates against heat loss | adipose connective tissue |
| voluntary controlled | skeletal muscle |
| involuntarily controlled | cardiac, smooth muscle |
| striated | skeletal, and cardiac muscle |
| has a single nucleus in each cell | cardiac and smooth muscle |
| has several nuclei per cell | skeletal muscle |
| found attached to bones | skeletal muscle |
| allows you to direct your eyeballs | skeletal muscle |
| found in the walls of the stomach, uterus, and arteries | smooth muscle |
| contains spindle-shaped cells | smooth muscle |
| contains branching cylindrical cells | cardiac muscle |
| contains, long nonbranching cylindrical cells | skeltal muscle |
| has interclated discs | cardiac muscle |
| concerned with locomotion of the body as whole | skeletal |
| changes the internal volume of an organ as it contracts | cardiac and smooth muscle |
| tissue of the heart | cardiac muscle |
| tissue used for transmitting signals | nervous tissue |
| Same height as width Single layer Block-like formation Round, dark nucleus in center | simple cuboidal epithelial |
| Secretion- process of separating or releasing a substance that fulfills some function in an organism | simple cuboidial epithelial |
| reticular fibers which are the main structural part of the tissue. | loose reticular connective tissue |
| The network of collagenous fibers in the reticular connective tissue provides support for blood cells: White blood cells Mast cells Macrophages | loose reticular connective tissue |
