Answer:

Cancellous bone tissue. Bone marrow and blood vessels.Question 2: List the 6 major types of synovial joints in order of decreasing range of motion.Assume the pivot joints offer slightly more motion than hinge joints.

Answer:

Ball-and-socket, saddle, ellipsoid, pivot, hinge, plane.

Question 3: Which gland secretes calcitonin?

Answer:

Thyroid.

Question 4: A bone-forming cell

Answer:

Osteoblast

Question 5: The following are processes that occur when bone is repaired. Order then according to the sequence in which they occur.

Answer:

The external callus is removed by the osteoclasts, and cancellous bone is remodeled as needed.

4.A hematoma forms.

1.The callus is ossified.

3.The callus forms. 2.Question 6: A person's medical tests show a large increase in the calcitonin levels of the body.What does that tell you about the calcium level in that person's blood?

Answer:

It was very high.

Question 7: What effect do the sex hormones have on bone growth?

Answer:

They stimulate it. They also stimulate ossification of the epiphyseal plates causing long bone growth to stop.

Question 8: What is the purpose of articular cartilage in a synovial joint?

Answer:

To protect the bones.

Question 9: A mass of connective tissue that connects the ends of a broken bone

Answer:

Callus

Question 10: What is the effect of calcitonin on bone cells?

Answer:

Decrease the activity of the osteoclasts, less calcium in blood.

Question 11: A mass of blood that is confined to a limited space

Answer:

Hematoma

Question 12: If a long bone has no epiphyseal plates because they have become epiphyseal lines, is there any way that a bone can grow?

Answer:

Yes. It can only grow in width.

Question 13: Which gland secretes PTH?

Answer:

Parathyroid.Question 14: What is the term for the layers of bone tissue that form an osteon? What is the terms for the layers of bone between osteons?

Answer:

Concentric lamellae. Interstitial lamellae.Question 15: Which gland secretes growth hormone, and what affect does this hormone have on bone tissue?

Answer:

Pituitary gland.Question 16: Looking at bone tissue under a microscope, you see no osteons. Is this compact or cancellous bone tissue?

Answer:

Cancellous.Question 17: What are the 3 major types of joints in the body, and which type is associated with most of the movement in the skeleton?

Answer:

Fibrous, cartilaginous, and synovial. Synovial.Question 18: There are at least 6 reasons why bone must be continually remodeled. Can you list at least 5 of them?

Answer:

Bone growth, to bear weight more easily, reshaping, healing breaks, convert cancellous bone to compact bone, increase/decrease mass based on stress, replace worn collagen or hydroxyapatite, regulate calcium levels in blood

Question 19: What are canaliculi?

Answer:

A channel in the bone that the osteocytes' processes go through.Question 20: Bone growth occurs when new cartilage is added to the bone's epiphyseal plate.Why doesn't the epiphyseal plate get thicker as the bone grows?

Answer:

New cartilage is being formed at the same rate that the cartilage at the other side is being ossified.Question 21: What is the purpose of the external callus? What is the purpose of the internal callus?

Answer:

To stabilize the bone as it reforms. To eventually become new bone tissue.

Question 22: What produces synovial fluid?

Answer:

The synovial membrane.Question 23: The position acquired when one stands erect with the feet facing forward, the upper limbs hanging at the sides, and the palms facing forward with thumbs to the outside

Answer:

Anatomical position

Question 24: A mature bone cell surrounded by bone matrix

Answer:

Osteocyte

Question 25: What is appositional bone growth?

Answer:

Bone growth in diameter rather than length.Question 26: A bone is completely surrounded by bone matrix. What kind of bone cell is it?

Answer:

Osteocyte.
