Answer 9

Skull, ribs, sternum, vertebrae(Concept 1 page 6)

Question 10

(19)There are four stages in the healing of a bone fracture. Which of the following best illustrates the sequence

Answer 10

Hematoma formation, fibrocartilage callus formation, bony callus formation, bone remodeling(Concept page 8-9)

Question 11

(23)A bone that has approximately the same width, length, and height

Answer 11

Short bone(Concept 1 page 6)

Question 12

(24)The bones in your wrist

Answer 12

Flat bone(Concept 1 page 6)

Question 13

(26)List four of the six overall functions of the skeletal system we discussed in class

Answer 13

Support, protect, aid in movement, storage of minerals and energy(Concept 1 page 5)

Question 14

(28) Where is the Humerus located

Answer 14

The humerus is the bone in your upper arm. It’s located between your elbow and your shoulder(BBD)

Question 15

(28) Where is the Ulna located

Answer 15

The ulna is located medially to the radius, placing it near the little finger.(BBD)

Question 16

(28) Where is the radius located

Answer 16

The radius is a long bone in the forearm. It lies laterally and parallel to ulna, the second of the forearm bones(BBD)

Question 17

(29) Place the following steps of the bone remodeling process in the correct order

Answer 17

Osteocytes release chemical signals to send osteoclasts to the damage, Osteoclasts return calcium and phosphate to the blood through resorption, Macrophages promote bone tissue remodeling, Osteoblasts come in and build new bone(Concept 1 page 9)

Question 18

(27)How is a female pelvis different than a males

Answer 18

In female the pubic arch is wider and the wider space around the sacrum provides for a birth canal, both of which accommodate for females to grow and birth an infant(Discovery Station)

Question 19

(31) Label the Spongey and compact bone in the picture on your answer sheet. Then describe, in detail, one structure unique to compact bone and one structure unique to spongey bone

Answer 19

Compact bone is composed of osteons which are like tiny weight bearing pillars in the bone that have a central canal running through the middle that contains small blood vessels and nerve fibers. Spongy bone doesn’t have osteons but does have trabeculate which are like tiny bone struts where the bone marrow is that also help the bone resist stress(Concept 1 page 7)

Question 20

(39)There are 28 phalanges in the human body

Answer 20

false 56(BBD)

Question 21

(42)Where is the Proximal Epiphysis located

Answer 21

very similar to the distal epiphysis, except it is on the other side of the diaphysis pointing toward the center of the body. It is also rounded, made up of spongy tissue, and covered in articular cartilage.(Concept 1 page 10)

Question 22

(43)Where is the Diaphysis located

Answer 22

The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone(Concept 1 page 10)

Question 23

(44)Where is the Distal Epiphysis located

Answer 23

The distal epiphysis is the rounded part of the bone found at the end of the diaphysis that is pointing away from the center of the body(Concept 1 page 10)

Question 24

(45)Where is the articular cartilage located

Answer 24

Articular cartilage is hyaline cartilage on the articular surfaces of bones, and lies inside the joint cavity of synovial joints(Concept 1 page 10)

Question 25

(47)Where is the medullary cavity located

Answer 25

Located in the main shaft of a long bone (diaphysis) (consisting mostly of compact bone), the medullary cavity has walls composed of spongy bone (cancellous bone) and is lined with a thin, vascular membrane (endosteum).(Concept 1 page 10)

Question 26

(49)Where is the mandible located

Answer 26

he mandible is the largest bone in the human skull. It holds the lower teeth in place, it assists in mastication and forms the lower jawline(BBD)

Question 27

(51)Where is the radius located

Answer 27

The radius is one of the two bones that make up the forearm, the other being the ulna. It forms the radio-carpel joint at the wrist and the radio-ulnar joint at the elbow(BBD)

Question 28

(54)Where are the tarsals located

Answer 28

a set of seven irregularly shaped bones. They are situated proximally in the foot in the ankle area.(BBD)

Question 29

(60) Where is the talus located

Answer 29

The talus is a small bone that sits between the heel bone and the two bones of the lower leg(BBD)
