| Question | Answer |
|---|---|
| supports and forms framework of the body. vascularized, extracellular matrix-ground substance-has blood supply | Connective tissue |
| entire gland and its products are secreted-sebaceous glands (hair)/glands that release entire cells | Holocrine Glands |
| glands that lose small portions of their glandular cell bodies during secretion-mammary glands ceruminous | Apocrine Glands |
| glands that release fluid products by exocytosis-salivary pancreatic glands | Merocrine Glands |
| looks like multiple layers, but really isn't; located in the trachea | Pseudostratified |
| example of epithelial covering; one layer thick, allows for absorption (lining of digestive tract) | Simple Covering |
| delicate network of interwoven fibers that function as a net (stroma) to support free blood cells (lymphatic tissue, bone marrow) | Reticular Tissue |
| covers the body surface and organs, forms the inner lining of body cavities and lines hollow organs | Epithelial Tissue |
| consists of several layers of cells, superficial cells are elongated, where the basal layers consist of cube shaped cells | Stratified Columnar Epithelium |
| secrete a protective fluid called mucus onto the free surface of the tissue -wax producing cells | Goblet Cells |
| loose-all other tissues and cells in the body are either bordered to or are embedded in it -tissue gives shape around other tissue | Areolar Tissue |
| fat- cells in fluid gel matrix, protects, insulates and stores fat | Adipose Tissue |
| loose connective | Soft |
| blood and lymph - connects all components of the body | Vascular |
| is composed of protein fibers and a ground substance consisting of nonfibrous protein and other molecules and fluid | Extracellular Matrix |
| oil (sebaceous secreting sebum) | Simple Branched Alveolar |
| sweat (sudoriferous) <- think of odor, stinky | Simple Coiled Tubular |
| is composed of a single layer of elongated cells whose nuclei are usually about the same level, near basement membrane, can be ciliated or nonciliated | Simple Columnar Epithelium |
| appear stratified or layered, but they are not. Layered effect occurs because nuclei are at 2 or more levels in a row of aligned cells | Pseudostratified Columnar Epithelium |
| column shaped, stratified located in male urethra (long narrow) entire length of digestive tract, nucli located at the base | Columnar |
| cube shaped, common in glands and their ducts, walls of kidney tubules and covers the surface of the ovaries | Cuboidal |
| middle covering, lines the ventral cavity of the body and covers the organs in that cavity; is a friction reducer | Mesothelium |
| inner covering, lining of blood and lymphatic vessels and the heart | Endothelium |
| consists of a single layer of thin, flattened cells, fit tightly together, somewhat like floor tiles, and their nuclei are usually broad and thin | Simple Squamous Epithelium |
| flat and irregular, thin flattened cells | Squamous |
| found in the urinary tract, highly modified stratified squamous epithelium | Transitional |
| located near blood vessels, release heparine-for prevention of blood clotting, and histamine which promotes some of the reactions associated w/ inflammation and allergies | Mast Cells |
| specialized for phagocytosis to fight infection (if too large, body will eat) function as scavenger cells that clear foreign particles from tissues | Macrophages |
| large star shaped cells that secrete fibers into the extracellular matrix of connective tissue (gives strength to prevent breaking through fibers) | Fibroblast |
| defined as a group of cells that are similar in structure and function | Tissue |
| multiple layers, allows for wear and tear (heel of your foot) | Stratified |
| non striated, involuntary muscle, walls of hollow organs, lacks striation, are shorter than those of skeletal muscle and are spindle shaped each w/single, centrally located nucleus | Smooth Muscle |
| striated, voluntary muscle, forms muscles that usually attach to bones and are controlled by conscious effort | Skeletal Muscle |
| gastric | Simple Branched Tubular |
| mammory glands | Compound Alveolar |
| bulbourethral glands (sperm nourishment) | Compound Tubular |
| striated, involuntary muscle, intercalated disks-contain gap junctions to allow passage of ions and form a binding site between fibers-only in the heart | Cardiac Muscle |
| intestinal | Simple Tubular |
| glands that secrete their products into ducts that open onto surfaces such as the skin or the lining of the digestive tract | Exocrine Glands |
| movement tissue; are contractible; they can shorten and thicken | Muscle Tissue |
| bone break down | Osteoclasts |
| glands that secrete their products into tissue fluid or blood (hormones) | Endocrine Glands |
| are groups of epithelial cells that make and secrete a product | Glands |
| bone building | Osteoblasts |
| consists of a single layer of cube shaped cells, usually have centrally located, spherical nuclei | Simple Cuboidal Epithelium |
| consists of many layers of cells making this tissue relatively thick | Stratified Squamous Epithelium |
| bone maintenance | Osteocytes |
| osseous tissue formed by osteocytes, built by osteoblasts, and broken down by osteoclasts | Bone |
| pinna of the ear-maximize movement and springs back; is more flexible than hyaline cartilage because extracellular matrix has a dense network of elastic fibers | Elastic Cartilage |
| consists of two or three layers of cuboidal cells that form the lining of a lumen | Stratified Cuboidal Epithelium |
| between segments of the spine; shock absorber for structures subjected to pressure, very tough tissue, has many collagenous fibers | Fibrocartilage |
| forms the ends over long bones, shock absorber; supports, protects, provides framework ends of bones, nose, and rings in walls of respiratory passages | Hyaline Cartilage |
| formed by chondrocytes; rigid connective tissue; provides support, frameworks, and attachments; protects underlying tissues, forms structural models for many developing bones | Cartilage |
| cartilage and bone | Hard |
| containing flexible white protein, collagen forming structures like: tendons, ligaments, the capsules (shell) of certain organs ie. kidneys - binds body parts | Fibrous (Dense Regular) Connective Tissue |
| main component of the nervous organs (brain, spinal cord and nerves) in charge of impulses | Nervous Tissue |
| impulse transporting cells (do thins w/out thinking)highly specialized | Neurons |
| information away; carry information away from cell-changes in their surroundings and repond by transmitting nerve impulses along cellular processes | Axon |
| information gathering; brings information into cell | Dendrite |
| cell body; determines what to do with information | Somite |
| support cells-do not transport impulses, nourish, insulate and protect neurons - cleans up after neuron (cell to cell communication) | Neuroglia |
