Answer:

35 and 40 years Question 3: The ulna articulates proximally with the:

Answer:

Humerus

Question 4: When the knee is flexed, the patella can be easily distinguished

Answer:

False. The patella (kneecap) is the largest sesamoid bone-one of the few that consistently appear in the human skeleton. (Patton, 032018)

Question 5: During childbirth, a baby passes through an imaginary plane called the

Answer:

Pelvic outlet Question 6: Young children's bones have a greater risk of fracturing because of incompletely ossified bone.

Answer:

False Question 7: In intramembranous ossification, the process of appositional growth refers to the:

Answer:

Addition of an outside layer of osseous tissue on flat bones

Question 8: Which of the following may cause skeletal variations?

Answer:

Inadequate supply of calcium and vitamin D, mechanical stresses, age Question 9: A condition that is caused by an abnormally increased roundness in the thoracic curvature is

Answer:

Kyphosis.

Question 10: The humerus articulates proximally with the clavicle

Answer:

False. The humerus articulates proximally with the scapula

Question 11: An open fracture is also known as a compound fracture

Answer:

True

Question 12: Before childbirth, the symphysis pubis softens

Answer:

True

Question 13: The following are functions of bone except for

Answer:

Support, protection, mineral storage, hematopoiesis

Question 14: Blood calcium levels involve secretion of which two hormones?

Answer:

Parathyroid and calcitonin Question 15: Appositional growth of cartilage occurs when chondrocytes begin to divide and secrete

Answer:

Additional matrix Question 16: Until bone growth in length is complete, a layer of the cartilage, known as the _____, remains between the epiphysis and diaphysis

Answer:

Epiphyseal plate Question 17: Small cells that synthesize and secrete a specialized organic matrix are

Answer:

Osteoblasts. Osteoblasts are small cells that synthesize and secrete an organic matrix called osteoid.(Patton, 032018) Question 18: Bones grow in diameter by the combined action of which two of the three bone cell types?

Answer:

Osteoblasts and osteoclasts Question 19: The cell organelles that synthesize organic matrix substances in bone formation

are:

Answer:

The cell organelles that synthesize organic matrix substances in bone formation are the endoplasmic reticulum and ribosomes. The osteon, or haversian, system delivers nutrients to and removes waste products from bone cells.

Question 20: The cells responsible for active erosion of bone minerals are called:

Answer:

Osteoclasts. Osteoclasts are giant multinucleate cells that are responsible for the active erosion of bone minerals. They are formed by the fusion of several precursor cells and contain large numbers of mitochondria and lysosomes (Patton, 032018).

Question 21: After the age of 50, the density of bone

Answer:

Decreases slowly because of a shift in the remodeling activity.

Question 22: Bones act as a reservoir for which of the following minerals?

Answer:

Calcium Question 23: Hematopoiesis is carried out in the:

Answer:

Red bone marrow Question 24: In the epiphyseal plate, the zone of hypertrophy is in the _____ layer

Answer:

Is the third layer. The next set of cell layers, called the zone of hypertrophy, is com-posed of older, enlarged cells that are undergoing degenerative changes associated with calcium deposition (Patton,

032018)

Question 25: Which structures are unique to the fetal skull and provide additional space for molding the head shape as the baby passes through the birth canal?

Answer:

Fontanels

Question 26: Which of the following is not a characteristic of the diaphysis?

Answer:

Provides a bulbous shape for attachment of muscle. Its hollow, cylindrical shape and the thick compact bone that composes it adapt the diaphysis well to its function of providing strong support without adding cumbersome weight. (Patton, 032018)
