Question 12

Collagen

Answer 12

Main extracellular protein of most connective tissues and is found predominately in the skin and bone.
Gives structure and shape to tissue.

Question 13

Reticular Fibers

Answer 13

Found in liver and spleen.

Gives framework and support for cellular organs.

Question 14

Elastic Fiber

Found in alveolar sacs and also in bones of young animals.

Allows for stretching of a tissue.

Question 15

Emphysema

Answer 15

A condition in which the alveolar sacs are damaged resulting in a decrease in pulmonary compliance.

Question 28

Osteoperosis

Answer 28

Estrogen levels drop and calcium is released

Question 29

Ossification

Answer 29

Production of bone

Performed by osteoblast

Thyroid and the Bone

Answer 30

Produces Calcitonin

Increases osteoblast numbers

Question 31

Osteomas

Thickening of bone (over-growth)

Question 32

Parathyroid and the Bone

Answer 32

produces parathyroid hormone (PTH) parathormone

Increases osteoclast numbers (overactive = thinning of bone)

Question 33

De-ossification

Answer 33

Breakdown of the bones
Performed by osteoclasts
Bones are never more than 7 years old
