Connective Tissue

Question 1

Ground substance

Answer 1

Water, adhesion protein, large charges polysaccharides

Question 2

Functions of connective Tissue

Answer 2

• protection
• support
• binding together other tissue

Question 3

Fiber types

Answer 3

• collagen (white): high tensile strength
• elastic (yellow): stretch & recoil
• reticular: internal skeleton of soft organs

Question 4

Bone

Answer 4

• Composed of osteocytes
• sits in lacunae (cavities), surrounded by a very hard matrix that has Ca2+ and P salts with collagen fibers
• many blood vessels
• support and connection

Question 5

Cartilage

Answer 5

• composed mainly of chondrocytes
• more flexible than bone
• avascular
• types: hyaline, fibrocartilage and elastic

Question 6

Hyaline

Answer 6

• most abundant
• supporting structure of the larynx
• attaches ribs to sternum
• cover the ends of many bones, where they form joints

Question 7

Fibrocartilage

Answer 7

-forms cushion like discs between the vertebrae of the spine

Question 8

Elastic cartilage

Answer 8

-found in structures of elasticity (i.e. ear)

Question 9

Dense connective Tissue

Answer 9

• composed of collagen fibers, in between rows are fibroblast
• strong, rope-like structure
• found in ligaments and tendons
• also make the dermis

Question 10

Loose connective Tissue

Answer 10

• softer, composed of more cells and has less fewer fibers than all other connective tissue except for blood
• types: areolar, adipose, and reticular

Question 11

Areolar Tissue
(Most widely distributed)

Answer 11

-soft, pliable, cobwebby
-“small open space”
-universal packing Tissue
(helps holds organs into place)
-lamina propria: underlies all mucous membrane
-defends against infection
-provides a reservoir of water and salts for surrounding tissues

Question 12

Adipose Tissue

Answer 12

• (areolar tissue with adipose cells predominating, 90% of mass)
• forms subcutaneous Tissue beneath the skin, for insulation, and protection against bumps and extreme temperatures
• site for energy storage
• cells swell and shrink as fats are added or removed

Question 13

Reticular connective Tissue

Answer 13

• reticular fibers with reticular cells interwoven
• forms stroma (internal framework for organs)
• supports many free blood cells (mainly lymphocytes) in lymphoid organs

Question 14

Blood

Answer 14

• surrounded by a nonliving fluid matrix
• consisting of blood cells surrounding blood plasma
• fibers of blood are soluble protein molecules that become visible during blood clotting

Question 15

Edema

Answer 15

-enlarged body part from soaking excess fluid from inflammation
