51. Which of the following breaks down bone material? a. osteoclasts b. osteoblasts c. canaliculi d. osteocytes: a. osteoclasts 52. Which of the following is considered a short bone? a. skull bone b. radius and ulna c. carpals and tarsals d. humerus and scapula: c. carpals and tarsals 53. Which of the following best describes the purpose of hyaline cartilage in the skeletal system? a. it forms the matrix of a bone b. it develops into osteocytes c. it strengthens the entire skeletal system d. it reduces friction: d. it reduces friction The covering at the end of long bones where joints form needs hyaline cartilage to reduce the friction of movement. 54. Which of the following best explains the cause of osteoporosis? a. Pathogens eat away at bone tissue. b. ligaments degrade, causing joints to malfunction c. Osteoclasts break down bone faster than osteoblasts deposit minerals. d. Osteoclasts break down bone slower than osteoblasts build them up.: c. osteoclasts break down bone faster than osteoblasts deposit minerals. More bone is being broken down that is being built up, causing bones to weaken and become brittle. Osteoclasts break down bone faster than osteoblasts deposit minerals. 55. Describe how the skeletal and muscular system work together?: The bones of the skeleton connect to the skeletal muscles with a connective tissue known as a "tendon." When the muscle contracts, it shortens, pulling the bone it is connected to.
