| Question | Answer |
|---|---|
| Group of skeletal muscle fibers are bound together by a connective tissue envelope called the | perimysium |
| The origin of muscle is on the femur, the insertion in on the tibia. When it contracts, it bend the knee. Its fibers run parallel to the body. What term might be part of its name? | Flexor |
| Another name for a skelatal muscle cell is a | muscle fiber |
| The plasma membrane of muscle fiber is called | sarcolemma |
| An articulation is a point of contact between bones. | TRUE |
| A symphysis is a joint in which bones are connected by fibrous bands. | FALSE |
| A gliding joint is a form of uniaxial joint. | FALSE |
| Eversion turns the sole of the foot outward. | TRUE |
| In bone growth the medullary cavity is enlarged because of the activity of? | osteoclasts |
| Functions of the bone are | support,protection,mineral storage, hematopoiesis |
| in the DNA molecule a sequence of three base pairs forms a? | codon |
| In which stage of mitosis do chromosomes move to the opposite end of the cells along the spindle fibers? | anaphase |
| the two processes of protein synthesis are | transcription, translation |
| the result of meiosis is | four daughter cells that are haploid |
| Which structure allows the electrical signals to travel along the sarcolemma and move deeper into the cell? | transverse tubule |
| Anaerobic respiration results in the formation of an incompletely catabolized molecule called | lactate |
| During which phase of the twitch contraction is there a triggering of the release of calcium ions into the sarcoplasm? | Latent period |
| Which joint allows for a unique movement called opposition? | saddle |
| Thick myofilaments extend the length of the: | A-band |
| The minimal level of stimulation required to cause a fiber to contract is called the | Threshold stimulus |
| Muscle tone is maintained by | Negative feedback mechanisms |
| Hematopoiesis is carried out in the: | Red bone marrow |
