Bone Biology and Ethics

Question 1

Musculoskeletal system functions

Answer 1

support the body, facilitate movement, protect internal organs, store minerals and fat, hematopoiesis (production of blood cells)

Question 2

Fibrous Joints

Answer 2

tightly connected by connective tissue, generally immovable (Skull sutures)

Question 3

Cartilaginous Joints

Answer 3

connected by cartilage, limited movement (pubic symphysis)

Question 4

Synovial Joints

Answer 4

Connective tissue and synovial cavity, very mobile (several types: ball and socket, hinge)

Question 5

Ligaments

Answer 5

connect bone to bone, strengthens joint but limits movement

Question 6

Flexion

Answer 6

Bending movement that decreases the angle between body parts

Question 7

Extension

Answer 7

Straightening movement that increases the angle between body parts

Question 8

Abduction

Answer 8

Movement of a body part away from the sagittal plane

Question 9

Adduction

Answer 9

Movement of a body part toward the sagittal plane

Question 10

Circumduction

Answer 10

Combination of abduction, adduction, flexion, and extension. Appendage moves in a cone shaped path

Question 11

Rotation

Answer 11

Motion that occurs as one body part turns on an axis

Question 12

Opposition

Answer 12

Motion in which body parts are brought together

Question 13

Osteogenic cells

Answer 13

develop into osteoblasts

Question 14

Osteoblasts

Answer 14

form bone

Question 15

Osteocytes

Answer 15

Maintain mineral concentration of bone matrix

Question 16

Osteoclasts

Answer 16

Resorption of bone
