| Question | Answer |
| How does a diarthrosis joint move? | moves freely (dia=through, apart) |
| what is supination | rotation of the forearm into anatomical position |
| ______________ is natural in anatomical position | extension |
| what do tendons hold together | muscle and bones |
| what is a meniscus | a pad of fibrocartilage |
| elongated cylinders of connective tissue line with synovial membran and wrapped around a tendon - like a bun on a hot dog | tendon sheath |
| inversion | sole of the foot turned medially |
| What do the anterior and posterior cruciate ligaments do for the knee joint | limit anterior and posterior sliding movements |
| What two things affect the movement at synovial joints | origin and insertion of the attached bones |
| joint in which two bones are separated by a space called a joint cavity | synovial joints |
| eversion | soles of the foot turned laterally |
| What are the six structures of a synovial joint? | articular cartilage, articular capsule, synovial fluid, menisucs, tendons, ligaments |
| what do ligaments hold together | bones to bones |
| what is dorsiflexion | raising the toes towards towards the shin |
| protraction | movement of a bone anteriorly (forward) on a horizontal plane |
| what is a combination of flexion, abduction, extension and adduction movements | circumduction |
| How does a amphiarthrosis joint move? | slightly moveable (amphi=both sides) |
| retraction | movement of a bone posteriorly |
| this joint is said to be three in one | knee joint |
| How does a synarthrosis joint move | just a little or no movement (syn=together, arthro=joint) |
| tendon sheaths and bursae dissipate | heat and friction |
| opposition | move thumb to touch the fingertips |
| what does extension do to the angle of a joint | increases the angle - bones move farther apart |
| How are synovial joints joined? | synovial cavity that contains fluid |
| what is meant by hyperextension | extending beyond 180 degrees |
| What is special about the glenohumeral joint | most freely movable joint in the body because of shallow glenoid and loose capsule |
| what is pronation | rotation of the forearm out of anatomical position |
| What type of joint is between the head of the humerus and the glenoid cavity of the scapula | ball-and-socket joint |
| what does flexion do to the angle of a joint | decrease the angle - brings boens closer together |
| What is the movement like for synovial joints | most are diarthrosis - move freely |
| joint where smooth head fits within a cuplike depression | ball-and-socket joint |
| How are joints classified? | by their freedom of movement and how bones are joined |
| saclike extension of a joint capsule that allows structures to slide more easily past each other | bursa (means "purse") |
| what do themedial and lateral collateral ligaments do for the knee joint | prevent rotation of extended knee |
