front 1 Tissues | back 1 a group of cells with a common embryonic origin performing a similar function |
front 2 4 types of tissue | back 2 epithelial=skin, covers body surfaces connective= protects, and supports the body muscular= produces force nervous= conducts electrical impulses |
front 3 epithelial tissue | back 3 tightly packed cells, little/no intercellular space, avascular, contains basement membranes |
front 4 layers of cells (epithelial) | back 4 simple, stratified, and pseudostradified |
front 5 simple epithelium | back 5 single layer of cells absorption and filtration minimal wear and tear |
front 6 stratified epithelium | back 6 cells stacked in several layers high degree of abrasion (wear and tear) |
front 7 pseudostratified epithelium | back 7 only one layer of cells, but looks like multiple. not all cells reach the free surface, many have cilia and mucous. |
front 8 shapes of cells | back 8 squamous cuboidal columnar transitional |
front 9 squamous | back 9 flattened or scale like cells |
front 10 cuboidal | back 10 box or cube shaped |
front 11 columnar | back 11 longer than wide |
front 12 transitional | back 12 combination of other shapes, can be found where structures can change shapes, very elastic and extensible |
front 13 endocrine glands | back 13 ductless glands, secretion diffuses into the blood, found in the pituitary, thyroid, and adrenal glands, and the pancreas. |
front 14 exocrine glands | back 14 secretes products into ducts, may enter at the surface or line the covering of the epithelium. found in sweat and salivary glands |
front 15 mucous membrane | back 15 lines structure with opening to the external environment, epithelial layer secretes mucous. lines respiratory, gastrointestinal, urinary, and reproductive tracts. |
front 16 serous membrane | back 16 lines body cavities that don't open to the external environment, consists of 2 layers (visceral and parietal) |
front 17 cutaneous membrane | back 17 the skin |
front 18 synovial membrane | back 18 contains no epithelial tissue, lines cavities of freely moving joints. lubricates and nourishes hyaline cartilage |
front 19 connective tissue | back 19 most abundant in body, tissue that binds and supports |
front 20 loose connective tissue | back 20 also called areolar connective tissue, loosely woven arrangement of fibers. found in mucous membranes, around blood vessels/nerves and body organs |
front 21 adipose tissue | back 21 loose connective tissue that contains adipocytes. fat droplets= triglycerides, major energy reserve |
front 22 cartilage | back 22 avascular, can withstand tremendous force |
front 23 types of cartilage | back 23 hyaline (articular) fibrocartilage elastic |
front 24 hyaline cartilage | back 24 most abundant, bluish white in appearance, reduces friction at joints. found at ends of long bones, ribs, embryonic skeleton. |
front 25 fibrocartilage | back 25 main purpose is shock absorbtion, more elastic than hyaline. found in invertebral discs, menisci of knee, epiglottis |
front 26 elastic cartilage | back 26 structural, provides rigidity/strength, maintains shape of some organs. found in the larynx, ear, trachea, Eustachian tubes, nose. |
front 27 dense fibrous tissue | back 27 composed of a close packed matrix of collagen fibers and fibroblasts that are either in regular or irregular arrangement |
front 28 dense connective tissue (regular) | back 28 adapted for tension in one direction, arranged in parallel fashion. found in tendons, aponeuroses, and ligaments. |
front 29 dense connective tissue (irregular) | back 29 found where multi-directional forces are found. located in most fascia, reticular region of skin. |
front 30 elastic connective tissue | back 30 freely branching fibers, provides strength/stretch but snap back to position when stretched. yellowish in color, found in trachea, bronchi, lungs, and vocal chords. |
front 31 reticular connective tissue | back 31 contains a special type of reticular fiber, found in framework of organs, liver, spleen, binds smooth muscle |
front 32 vascular tissue | back 32 blood. made up of plasma, red blood cells, white blood cells, and platelets. |
front 33 osseus tissue | back 33 maintained by special cells, two types (compact and spongy) |
front 34 muscle tissue | back 34 made of muscle cells, highly specialized, converts chemical energy into mechanical energy, 3 types (skeletal, cardiac, and smooth) |
front 35 nervous tissue | back 35 highly specialized and sensitive tissue. capable of converting stimulus to nervous impulses. transmits to other neurons, glands, and muscle fibers |
front 36 nerve cells (neurons) | back 36 made up of the cell body, axons, and dendrites |
