Anatomy Lecture Test #2 Chapter 6

Front 1

Hematopoiesis takes place in the ____ of some adult bones.

Back 1

Red bone marrow

Front 2

In adults, lipids are stored in the _____

Back 2

Yellow bone marrow

Front 3

The periostium is attached to the underlying bone through _____

Back 3

Perforating (sharpey's) fibers

Front 4

The extracellular matrix of bone tissue is made up of:

Back 4

15% water, 30% collagen, and 55% crystallized mineral salts

Front 5

When there is too little calcium in blood, which cells begin resorption of bone to release calcium to the blood?

Back 5

Osteoclasts

Front 6

If central (Haversian) canals become blocked the osteocytes:

Back 6

Die from lack of nutrients

Front 7

Explain support

Back 7

the skeletal system supports soft tissue and provides attachment points for tendons

Front 8

Explain mineral homeostasis

Back 8

Bone tissue stores 99% of the body's calcium. Bone releases minerals into the blood to maintain critical mineral balances

Front 9

Explain blood cell reproduction

Back 9

Red bone marrow produces red blood cells, white blood cells, and platelets.

Front 10

What is hemopoiesis?

Back 10

Process of making blood cells (red, white, and platelets)

Front 11

Explain triglyceride storage

Back 11

Yellow bone marrow consists mainly of adipose cells, which store triglycerides.

Front 12

What is periostium?

Back 12

Consisting of dense regular connective tissue, promotes bone growth in width or diameter.

Front 13

What is the endostium?

Back 13

Lines the medullary cavity providing the ability to remodel the bone.

Front 14

What happens during resorption?

Back 14

Bone cells break down bone tissue and release calcium and other minerals for use in the body

Front 15

What happens during deposition?

Back 15

Bone cells rebuild bone tissue by depositing minerals obtained from the bloodstream
