Ch. 4 Connective Tissue

Question 1

4 main classes of Connective Tissue

Answer 1

1. Connective tissue proper
2. Cartlidge
3. Osseous tissue (bone)
4. Blood

Question 2

Functions of the Connective tissue

Answer 2

Buinding (connection) and support
Protection
Insulation
Transportation

Question 3

Structural Elements of Connective Tissue

Cell Type

Answer 3

Fibrocyte
Chondrocyte
Osteocyte
Red Blood Cells/ White Blood Cells

Question 4

Structural Elements of Connective Tissue 
Extarcellular Matrix (ECM) composed of:

Answer 4

• Ground substance: holds water and ranges from liquid to jello to firm. Composed of [ Water, Adhesion protection, Polysaccharide molecules]
• Fibers: are produced by the cells.
  3 types are:
  Collagen Fibers: Extremely tough; high tensile strength.
  Elastic Fibers: that stretch and recoil.
  Reticular Fibers: Fine collagen, but more give

Question 5

Connective Proper Tissue

Answer 5

Loose Areolar
Lose Adipose
Dense Regular
Dense Irregular

Question 6

Loose Areolar

Answer 6

Fibrocyte
Skin to muscles
Macrophages phagocytize bacteria.
Binds, packages organs, surrounds capillaries.

Question 7

Loose Adipose

Answer 7

Fibrocyte
Insulates, supports, protects organs.
In kidney, eyeball, breast, abdomen.

Question 8

Dense Regular

Answer 8

Max strength.
Parallel collagen fibers. Being pulled in one direction.
Muscles to bones.
In Ligaments, tendons

Question 9

Dense Irregular

Answer 9

Joints, fibrous capsules of organs, Strength in many directions.

Question 10

Hyaline

Answer 10

Cartlidge: strength, support, absorb compressive shock, cushion resists stress.

Question 11

Fibrocartlidge

Answer 11

Intervertebral discs, Pubic symphysis, knee joint discs.

absorb shock.

Question 12

Elastic

Answer 12

Cartlidge, stretchability

outer ear, respiratory passage way.

Question 13

Bone (Osseous)

Answer 13

Protects, provides levers for muscle to act on.

Stores minerals, forms blood in marrow.

Question 14

Blood

Answer 14

In blood vessels. Transports gases, wastes, oxygen, and nutrients.

Question 15

Fibrocyte

Answer 15

Connective Tissue

Question 16

Chondrocyte

Answer 16

Cartlidge

Question 17

Osteocyte

Answer 17

Bone (Osseous)

Question 18

Red and White Blood Cells

Answer 18

Blood

Question 19

Extracellular Matrix

Answer 19

Ground Substance

Fibers

Question 20

Ground Substance

Answer 20

Unstructured material that fills the space between the cells that contain the fibers.
Holds water and ranges from liquid to jello to firm.
Adhesion proteins: serve as connective tissue glue that allows CT cells to attach to matrix elements.
Polysaccharide molecules: Protein core, GAG’s- large negatives charged polysaccharides that stick out from the core protein that trap H2O Nutrients and other dissolved substances diffuse between blood capillaries and the cells makes it less pliable hinders diffusion.

Question 21

Fibers

Answer 21

Produced by the cells
Collagen Fibers
Elastic Fibers
Reticular Fibers

Question 22

Collagen Fibers

Answer 22

Thick pink, Extremely tough; high tensile strength, abundant. Collagen molecules are secreted into extracellular space bundling together into thick collagen fibers. Resist being pulled apart.

Question 23

Elastic Fibers

Answer 23

Long dark black fibers that stretch and recoil. Rubber like proteins elastin. Found in skin, lungs, blood vessel walls.

Question 24

Reticular Fibers

Answer 24

Short fine delicate networks
Fine collagen, but more give.
Surround small blood vessels, support the soft tissue of organs. Abundant in basement membrane of epithelial tissue around capillaries from fuzzy nets allow more give than longer collagen fibers.
