Connective Tissues

Front 1

What are the general characteristics of connective tissues?

Back 1

bind structures, provide support and protection, serves as frameworks, fulls spaces, stores fat, produces blood cells, protects against infections, and helps repair tissue damage

cells have intercellular materials called matrix between them

Front 2

What are the types of cells in connective tissues?

Back 2

fibroblasts

macrophages

mast cells

Front 3

What are fibroblasts?

Back 3

large star shaped cells that produces fibers by secreting proteins into the matrix

Front 4

What are macrophages?

Back 4

specialized cells that carry on phagocytosis

they serve as scavangers

Front 5

What are mast cells?

Back 5

large cells that release heparin which prevents blood from clotting and histamine in response to inflamation and allergies

Front 6

What are the types of connective tissue fibers?

Back 6

collagenous fibers

elastic fibers

reticular fibers

Front 7

What are collagenous fibers?

Back 7

thick thread like fibers made from protein collagen

they are white in appearance and very strong

Front 8

What are elastic fibers?

Back 8

composed of thin fibers called elastin

they are yellow in appearance and stretch easily

Front 9

What are reticular fibers?

Back 9

very thin collagenous fibers that form supporting networks in a variety of tissues

Front 10

What are the types of connective tissues?

Back 10

loose fibrous connective tissue

adipose tissue

dense fibrous connective tissue

cartilage

Front 11

What is the loose fibrous connective tissue's function?

Back 11

it forms thin membranes throughout the body

it binds the skin to the underlying organs and fills spaces between muscles

Front 12

What is the adipose tissue's function and where is it found?

Back 12

Function: it stores fat, cushions joints and organs such as the kidneys, provides insulation and stores energy

Found: beneath the skin, between muscles, around the kidneys in certain abdominal membranes on the surface of the heart, and around certain joints

Front 13

What does the dense fibrous connective tissue include and where is it found?

Back 13

Include: thick collagenous fibers and a fine network of elastic fibers. it has poor blood supply

Found: in tendons, ligaments, the white layer of the eye ball, and the dermis of the skin

Front 14

What is cartilage and where is it found?

Back 14

it is partly rigid and partly flexible

Found: at the end of various bones, in the ear, larynx and pads between the backbone, pelvic girdle, and knee

Front 15

What are the types of cartilage in connective tissues?

Back 15

hyaline

elastic

fibrocartilage

Front 16

What is hyaline cartilage?

Back 16

most common type found on the end of bones (joints) and the tip of the nose

Front 17

What is elastic cartilage?

Back 17

more flexible, provides the framework for the external ears and part of the larynx

Front 18

What is fibrocartilage?

Back 18

very tough, it is often a shock absorber for structures subjected to pressure

they form pads between the backbone, knees, and pelvic girdle

Front 19

What is a bone and what is it made of?

Back 19

bone is an active tissue thhat heals rapidly

the intercellular matrix of bone contains mineral salts and collagen. its cells are usually organized in concentric circles around osteonic canals and are interconnected by canaliculi

Front 20

What makes up blood and what is it's function?

Back 20

it is composed of red cells, white cells, and platelets suspended in plasma. blood cells develop in red marrow in the hollow parts of long bones

Function: it transports substances and helps maintain a stable internal environment
