Test Review SKELETAL AND MUSCULAR SYSTEMS ball-and-socket joint knee joint that allows bones to “glide” over each other elbow Blood Vessel Compact Bone Marrow Spongy bone fills the center and spaces at the ends of bones and produces blood cells marrow OF THE FOLLOWING, THE STRUCTURE THAT IS NOT PART OF THE AXIAL SKELETON IS THE backbone rib cage arms and legs skull WHICH OF THE FOLLOWING DO NOT PASS THROUGH HAVERSIAN CANALS? blood vessels nutrients nerves muscle fibers Compact bone contains tightly packed osteocytes WHICH OF THE FOLLOWING WOULD NOT HELP PREVENT BONE LOSS? calcium regular exercise a balanced diet avoiding UV radiation The point where two or more bones meet is called a joint Smooth muscles can be found in internal organs Muscle cells get the energy needed to contract from ATP What is the difference between cartilage and bone? Bone contains significant mineral deposits between its cells, while cartilage does not. SMOOTH MUSCLE can change the diameter of blood vessels. moves food through the digestive tract. is not under conscious control. The total amount of force that a muscle exerts depends on the total number of individual muscle fibers that have been stimulated Ligaments attach bone to bone It has been known for a long time that muscle contraction requires ATP. Scientists have discovered that ATP is required to release the attachments between actin and myosin in the many cycles of attachment, release, and reattachment that result in sliding of these filaments past each other. Which of the following phenomena can be explained by this specific role of ATP? muscle fatigue Tendons are bands of tissue that connect muscles to bones Flexors and extensors are examples of voluntary muscles The loss of bone density that may occur in the later years of life is called osteoporosis In an embryo, the skeleton is originally made of cartilage Yellow marrow is a soft tissue within bones that consists mainly of fat and stores energy A person with a broken pelvic bone would probably be unable to walk or run The heart and lungs are protected by the rib cage WHICH AREA SHOWS WHETHER YOU WILL GET TALLER? GROWTH PLATE WHAT IS AREA A? SPONGY BONE WHAT IS AREA C? YELLOW MARROW WHAT IS AREA D? COMPACT BONE An embryo’s skeleton is made of? CARTILAGE Helps prevent bone loss? Calcium regular exercise balanced diet limited UV radiation
