characteristics, functions & locations (connective, epidermis, muscle, nervous)
| Question | Answer |
|---|---|
| Dense Regular C.T | C: densely packed collagen fibers are parallel to direction of stress F: attaches muscle to bone and bone to bone; resists stress applied in one direction L: Tendons and Ligaments |
| simple cuboidal | C: single layered cubed like cells, nucleus is well rounded F: secretion and absorption; secretion of mucin L: lining body cavities (thoracic, pericardium, abdominal) kidney tubules, cover ovaries |
| Simple Columnar | C: tall, appear columnar, sections are perpendicular to membrane, may contain goblet cells that secrete mucin F: secretion and absorption L: lines most digestive tract |
| Stratified Colunmar | C: RARE. column shaped cells arrange in multiple layers F: Secretion and protection L: pharynx, anus, female uterus, male urethra and large ducts of some exocrine glands |
| straitified Cuboidal | C: 2-3 layers of round nucleus in cubed shaped cell at apical surface F: protection and secretion L: sweat glands, mammary glands and salivary glands |
| adipose ct | C: nucleus of adipocyte, vacuole containing fat droplet F: stores lipids 'fats' for fuel and thermal insulation and cushions organs, insulation, shock abosorber L: under skin surrounding organs, breast and cavities within bones. and kidneys |
| stratified squamous epithelium | C: cuboidal as layer, degenerate surface cells, withstand moderate abrasion F: protection L: mouth, vagina, anal canal and esophagus |
| Pseudostratified columnar ciliated (PSCC) | C: all tissue begin @ basement membrane, nuclei appears at various levels, and cilia F: protection; ciliated form also involved in secretion of musin and movement of mucus across surface by ciliary action L: nasal septum, trachea, bronchi and larynx |
| transitional | C: stratified squamous/cubodial appearance and appears to be 4-5 layers thick F: distention L: ureter, urinary bladder |
| Loose Areolar C.T | C: fibers, ground substance, matrix, elastic fiber, fibroblast and nuclei F: binds tissue, skin connects to muscle, protection, nourishment to the organs and structure it binds, stores "body fluid" L: beneath skin, around blood vessel, nerves and muscle |
| elastic connective tissue | C: elastic fibers, lumen of artery of veins F: elastic fibers can stretch 1 1/2 their length and then recoil, fibers provide elasticity to tissues L: elastic fibers, lumen of artery or vein |
| Blood C.T | C: REd blood cells, white blood cells and platelets F: carry oxygen and glucose to cells L: under skin |
| simple squamous | C: one layered, flattened, irregularly shaped cells forming a continuous surface. F: Diffusion and Filtration L: covering visceral organs, capillary walls and aveoli of lungs |
| Dense Irregular C.T | C:collage fibers, randomly arrange and clumped together; fibroblasts in spaces among fibers; more ground substance than in dense regular c.t. F: provides strength in tissues L: dermis of skin, periosteum, joint capsules, heart valves, dura mater |
| Simple cuboidal | C: block appearance, nucleus is well rounded F: Secretion, excretion and absorption L: Lining Kidney tubules, salivary ducts and pancreatic ducts |
| reticular C.T | C: Nuclei of reticular fibers, reticular fibers. Thin and netted F: forms stroma of lymphatic organs L: stroma spleen, cavities in lymph nodes, liver and bone marrow |
| Areolar loose c.t | C: mostly ground substance, looks like fiberglass, lesser amount f collagen and elastic fibers F: binds and packs around organs L: surrounding nerves, vessels; and subcutaneous layer |
| elastic cartilage C.T | C: elastic and collagen fibers are arrange irregularly F: provides framework and supports organs L: walls of large arteries |
| Fibrocartilage CT | C: visible, parallel collagen fibers in matrix; lucunae house chondrocytes; no perchondrium F: shock absorbers L: between interbertebral disks, pubis symphysis and knee joint |
| Hyaline Ct | C: looks like glass. clear, living in tissue; two chondrocytes per lacuna F: support with flexibility, forms smooth surfaces in joints L: nasal cartilage, ends of long bones, connects ribs to sternum and "C" shaped rings in trachea |
| blood c.t | C: red spots, F: transport, themoregulation, defense agianst pathogens and communication L: blood |
| bone C.T | C: looks like tree rings F: support, protection L: outer layer of bones |
| ciliated simple columnar epithelium | C: single layer of tall, narrow ciliated cells, oval nucleas oriented lengthwise in teh basal region of the cell F: secretion of mucin and movement along apical surface L: ling of uterine tubes and large brochioles of respiratory tract |
| non keratinized stratified squamous | C:multiple layers or cells, basal cells typically are cuboidal or polyhedral, while apical cells are squamous, surface cells are alive and kept moist F: protection of underlying tissue L: oral cavity, part of pharynx, esophagus, vagina and anus |
| keratinized stratified squamous | C: multiple layers or cells, basal cells typically are cuboidal or polyhedral, while apical cells are squamous; more superficial cells are dead and filled with keratin F: protection of underlying tissue L: epidermis of skin |
| NON CILIATED PSEUDOSTRATIFIED COLUMNAR | L: RARE; LINES EPIDIDMYMIS AND PART OF MALE URETHA |
| Skeletal Muscle | C: fibers are long, cylindrical, striated, parallel and un branched. F: moves skeleton; responsible for voluntary body movement, locomotion, heat production L: attaches to bones or sometimes to skin (facial, muscles) also in sphincters-lips, urethra, anus |
| cardiac muscle tissue | C: cells are short, bifurcated and straited, with one or two centrally located nuclei, intercalated discs between cells F: involuntary contraction and relaxation pump blood in heart L: heart wall (myocardium) |
| smooth muscle tissue | C: cells are fusiform, short, nonstriated, and contain one centrally located nucleas F: involuntary movements and motion; moves materials through internal organs L: walls of hollow internal organs, such as vessels, airways, stomach, bladder, uterus |
| nervous tissue | C: neurons w/rounded cell bodies and an axon and dendrites extending from the cell body; glial cells lack extensive fibrous processes F: neurons, for control, info processesing, storage, and retrieval internal communication L: brian , spinal chord, nerves |
