Answer 3

bones (206)

Question 4

functions of bone

Answer 4

form the framework of the body
serve in structure and movement
protect internal organs
store minerals (calcium and phosphate)
act as site of blood cell formation

Question 5

divisions of skeletal system

Answer 5

axial and appendicular skeleton

Question 6

axial skeleton

Answer 6

consists of bones at the core of the body; skull, spine, ribs, and sternum

Question 7

appendicular skeleton

Answer 7

consists of the bones of the appendages of the body; shoulder girdle, arms, hands, pelvic girdle, legs, and feet

Question 8

bone shapes

Answer 8

long, flat, short, irregular, sesamoid

Question 9

long bones

Answer 9

located in the arms and legs
ex: femur

Question 10

flat bones

Answer 10

located in the shoulder, skull, ribs, and parts of pelvis
ex: sternum or skull bones

sesamoid bones

Answer 13

shaped like a sesame seed
ex: patella (kneecaps)

Question 14

accessory structures of skeletal system

Answer 14

cartilage, tendons, and ligaments

Question 15

cartilage

Answer 15

fibrous connective tissue
found at the ends of bones, in the joints, and the tube structures of the body
ex: larynx, air passages, and ears

Question 16

tendons

Answer 16

fibrous cords; connect muscles to bones

Question 17

ligaments

Answer 17

fibrous tissues in bands or sheets
connect two or more bones, cartilages, or other structures
help support fascia and muscles

Question 18

primary organ of muscular system

Answer 18

muscle

Question 19

muscle functions

Answer 19

enable movement
produce heat
maintain stability and posture

Question 20

joint

Answer 20

point where two or more bones connect

Question 21

parts of skeletal muscle

Answer 21

origin, body, and insertion

Question 22

types of joints

Answer 22

fibrous, cartilaginous, synovial

Question 23

fibrous joint

Answer 23

provide NO movement
found between bones of the skull

Question 24

cartilaginous joint

Answer 24

provides slight movement
found between vertebrae of spine

Question 25

synovial joint

Answer 25

provides free movement in multiple directions
mobility due to synovial fluid within the joint (lubrication)
found in hips, knees, shoulders, elbows, wrists, and ankles
