Chapter 6 Skeletal System: Bones and Bone Tissue
- Important functions of the skeletal system include
- protection of the brain and soft organs.
- storage of water.
- production of Vitamin E.
- regulation of acid-base balance.
- integration of other systems.
- Cartilage
- is composed of osteons.
- is surrounded by a membrane called the periosteum.
- contains chondrocytes located in lacunae.
- does not need nutrients and oxygen so it has no blood vessels.
- is well vascularized.
- Collagen and calcium hydroxyapatite are the primary constituents of
- bone matrix.
- hyaline cartilage.
- fibrous cartilage.
- The primary function of osteoblasts is to
- prevent osteocytes from forming.
- resorb bone along the epiphyseal plate.
- inhibit the growth of bone.
- stimulate bone growth.
- lay down bone matrix.
- A cord of connective tissue that attaches muscle to bone is a
- muscle spindle.
- A passageway connecting neighboring osteocytes in an osteon is a
- central canal.
- Which of the following is correctly matched?
- short bone – carpal bone
- long bone – vertebra
- irregular bone – femur

- short bone – humerus
- What is the area where marrow is located?
- epiphysis
- Sharpey’s fibers
- growth plate
- medullary cavity
- endosteum
- Which of the following events occurs last in intramembranous ossification?
- Osteoprogenitor cells become osteoblasts.
- A membrane of delicate collagen fibers develops.
- Cancellous bone is formed.
- Periosteum is formed.
- Many tiny trabeculae of woven bone develop.
- Which of the following statements regarding calcium homeostasis is true?
- Parathyroid hormone inhibits osteoclast activity.
- When blood calcium levels are too low, osteoclast activity increases.
- Increased osteoblast activity increases blood calcium levels.
- Parathyroid hormone increases calcium loss from the kidney.
- Calcitonin elevates blood calcium levels.

- Which of the following statements is true?
- The first cervical vertebra is called the axis.
- The spinal cord protects the vertebral column.
- Thoracic vertebrae have long, thin spinous processes.
- The sacral vertebrae are superior to the lumbar vertebrae.
- Lumbar vertebrae are generally smaller than thoracic vertebrae.
- The opening in vertebrae for the spinal cord is the

- The acromion process
- is part of the clavicle.
- articulates with the coracoid process.
- forms the most inferior part of the glenoid fossa.
- has no function.
- has an articulation with the clavicle.
- A woman pinched her phalange. She hurt her
- toe or her finger.
- Which of the following statements about the femur is TRUE?
- The head of the femur articulates with the tibia.
- The medial condyle articulates with the acetabulum.
- Both the greater and lesser trochanters are attachment sites for muscles.
- The distal end of the tibia articulates with the femur.
- The proximal end of the femur articulates with the tibia.

Chapter 8 Articulations and Movement
- A place where two or more bones come together is a(n)
- joint and an articulation.
- Joints are classified according to the
- bones that are united at the joint.
- structure of the joint.
- size of the joint.
- shape of the joint.
- type of fluid in the joint.
- Cartilaginous joints
- are common in the skull.
- unite two bones by means of fibrocartilage or hyaline cartilage.
- allow the most movement between bones.
- are found in the lower leg.
- are not found in the pelvic region.
- Synovial joints are different from both fibrous and cartilaginous joints because synovial joints
- use fibrous connective tissue to hold the bones in the joint together.
- are enclosed by a joint capsule.
- are only temporary; they are replaced in the adult.
- generally have both bones in the joint fused together.
- are not freely moveable.
- Synovial fluid
- is a double layer of tissue that encloses a joint.
- is a thin lubricating film covering the surface of a joint.
- provides a smooth surface where bones meet.
- is a layer of tissue that is continuous with the periosteum.
- lines the joint everywhere except over the articular cartilage.
- This type of joint is multiaxial allowing a wide range of movement.
- saddle
- hinge
- pivot
