Anatomy chapter 6
| Question | Answer |
|---|---|
| The type of bone that is made of osteons is | compact |
| The type of bone that is NOT made of osteons is | spongy |
| Flat and irregular bones are made primarily of | spongy |
| The shafts of long bones are made primarily of | compact |
| New bone matrix for growth is produced by cells called | osteoblasts |
| Reabsorption of bone matrix is the function of the cells called | osteoclasts |
| The function of osteoblasts is to | produce bone matrix |
| The function of osteoclasts is to | reabsorb bone matrix |
| Red bone marrow produces | RBCs,WBCs,platelets |
| All of the kinds of blood cells are produced in the | red bone marrow |
| The primary hemopoietic tissue is | red bone marrow |
| The type of bone marrow that is found in flat and irregular bones is | red bone marrow |
| The embryonic cranial bones are first made of | fibrous connective |
| In the embryo, the cells that produce bone matrix are | osteoblasts |
| The fontanels of an infant skull are made of | fibrous connective tissue |
| The embryonic humerus and femur are both made of | cartilage |
| In a child's long bones, growth occurs at the | epiphyseal discs |
| On the epiphysis side of an epiphyseal disc, the process taking place is the | epiphyseal discs |
| On the diaphysis side of an epiphyseal disc, the process taking place is | replacement of cartilage by bone |
| The inherited maximum height a child can attain is called the | genetic potential |
| Calcium and phosphorus are nutrients necessary to become part of the bone | matrix |
| The nutrient needed for the absorption of calcium in the small intestine is | vitamin D |
| Two vitamins necessary for the calcification process in growing bones are | A and C |
| The hormone that increases the reabsorption of calcium from bones is | parathyroid hormone |
| The hormone that decreases the reabsorption of calcium from bones is | calcitonin |
| Calcium is needed in the blood for the process of | clotting |
| The hormone in women that promotes closure of the epiphyseal discs is | estrogen |
| The hormone in men that promotes closure of the epiphyseal discs is | testosterone |
| The hormone that provides energy for bone growth from all three food types is | thyroxine |
| The hormone that provides energy for bone growth only from glucose is | insulin |
| The hormone that contributes to bone growth by increasing the rate of mitosis is | growth hormone |
| The hormones that contribute to bone growth by increasing the rate of protein synthesis are | thyroxine and growth hormone |
| Two hormones that provide the ATP production needed for growing bones are | insulin and thyroxine |
| One function of the occipital and parietal bones is the same in that they | protect the brain |
| The bone that protects the receptors for hearing is the | temporal bone |
| Two bones that protect the eye are the | frontal and sphenoid |
| The air cavities in the maxillae and frontal bones are called | paranasal sinuses |
| Two bones that contain paranasal sinuses are the | frontal and maxilla |
| The paranasal sinuses are lined with | ciliated epithelium |
| The sinus in the skull that does NOT provide resonance for the voice is the | mastoid sinus |
| The heart and liver are protected from mechanical injury by the | rib cage |
| The manubrium and xiphoid process are both parts of the | sternum |
| The rib cage with its muscles is directly involved in the functioning of the | respiratory system |
| The vertebral column contains and protects the | spinal cord |
| The shoulder joint is formed by the | humerus and scapula |
| The hip joint is formed by the | femur and hip bone |
| The shoulder and hip joints are similar in that both are | ball-and-socket joints |
| The glenoid fossa and the acetabulum are both part of | ball-and-socket joints |
| The type of joint that permits the greatest range of movement is the | ball-and-socket joints |
| The type of joint that does not permit movement is the | suture |
| The humerus and ulna form a | hinge joint |
| The femur and tibia form a | hinge joint |
| The two pubic bones form a | symphysis jonit |
| The atlas and the axis form a | pivot joint |
| The ulna and radius form a | pivot joint |
| The metacarpal of the thumb and the adjacent carpal form a | saddle joint |
| The parietal and temporal bones form a | suture joint |
| The mandible and temporal bone form a | condyloid joint |
| The function of synovial fluid is to | prevent friction |
| Preventing friction in a joint cavity is the function of | synovial fluid |
| The bone surfaces in a synovial joint are smooth because of the presence of | articular cartilages |
| The function of a bursa in a joint is to permit the sliding of a | tendon |
| Of pivot, saddle, and suture joints, the one that is not a synovial joint is the | suture |
| Of condyloid, gliding, and symphysis joints, the one that is not a synovial joint is the | symphysis |
| what is the bone features of Foramen | hole opening |
| what is the bone features of Fossa | dent |
| what is the bone features of Crest | edge |
| what is the bone features of meatus | passage way |
| what is the bone features of process | a projection |
| what is the bone features of facet | a flat projection |
| what is the bone features of condyle | rounded projection |
| what is the bone features of plate | flat projection |
| what is the bone features | round projection |
| what is the bone features | round projection |
| what is the function of the skull | to protect the brain |
| what is the function of the ribs | to protect the heart and lungs |
| what provides a smooth surface when joints are moved | cartilage |
| the process of bone replacement of another tissue is called | ossification |
| the production of bone matrix is accomlished by cells called | osteoblasts |
| in the embryo the cranial and fcial bones are first made of which tissue | fibrous connective tissue |
| necessary for the process of bone formation | vitamin C & A |
| becomes part of the collagen in bone matrix | protein |
| becomes part of the salts of bone matrix | calcium and phoshorus |
| necessary for the adsorption of calcium and phosphorus in the small intesine | vitamin D |
| what hormone lowers the blood calcim level | calcitonin |
| what hormone raises the blood calcim level | parathyriod |
| what hormone causes bones to stop growing | estrogen |
| name two organs in the upper abdominal cavity that are protected from mechanical injury by the rib cage | liver and spleen |
| which of these two bones forms the socket for the humerus | scapula |

| lines the joint capsule and secretes synovial fluid | synovial membrane |
| prevents friction within the joint cavity | synovial fluid |
| made of fibrous connective tissue encloses the joint like a sleeve | joint capsule |
| saca of synovial fluid that permit tendons to slide easily across a joint | bursae |
| provides a smooth surface on the joint surface of bones | articular cartilage |
| the largest bone of the arm and leg are | humerus/femur |
| the nutrients that become part of the bone matrix are | calcium and phosphorus |
| what hormone increases the rate of mitosis in growing bones | thyroxine |
