lab 9-connective tissue(test 1)

Question 1

areolar connective

Answer 1

cells in abundant fluid-gel matrix, loose arrangement of collagen and elastic fibers

function: loosely binds organs, holds tissue fluids
location: around body organs, binds skin to deeper organs

Question 2

adipose

Answer 2

cells is sparse fluid-gel matrix, closely packed cells

function: protects, insulates, stores fat
location: hypodermis, around kidneys and heart, yellow bone marrow, breasts

Question 3

reticular connective

Answer 3

cells in fluid-gel matrix, reticular fibers

function: supportive framework of organs
location: spleen, thymus, lymph nodes, red bone marrow

Question 4

dense regular connective

Answer 4

cells in fluid-gel matrix, parallel, wavy collagen fibers

function: tightly binds body parts
location: tendons, ligaments

Question 5

dense irregular connective

Answer 5

cells in fluid-gel matrix, random collagen fibers

function: sustain tissue tension
location: dermis, heart valves, periosteum on bone

Question 6

elastic connective

Answer 6

cells in fluid-gel matrix, collagen fibers densely packed, branched elastic fibers

function: provides elastic quality
location: larger artery walls, vocal cords, some ligaments between vertebrae

Question 7

hyaline cartilage

Answer 7

cells in firm solid-gel matrix, fine network of collagen fibers, appears glassy

function: support, protect, provides framework
location: nasal septum, larynx, costal cartilage, ends of long bones, fetal skeleton

Question 8

fibrocartilage

Answer 8

cells in firm solid-gel matrix, abundant collagen fibers

function: support, protect, provides flexible framework
location: between vertebrae, between pubic bones, pads in knee

Question 9

elastic cartilage

Answer 9

cells in firm solid-gel matrix, weblike elastic fibers

function: support, protect, provides flexible framework
location: outer ear, epiglottis

Question 10

bone

Answer 10

cells in solid matrix, many collagen fibers
function: supports, protects, provides framework
location: compact- bone shafts, beneath periosteum
spongy- ends of long bones, inside flat and irregular bones

Question 11

blood

Answer 11

cells and platelets in fluid matrix called plasma

function: transports nutrients, wastes, and gases, defends against disease, clotting
location: lumens of blood vessels, heart chambers
