Movement (Anatomy)
| Question | Answer |
|---|---|
| the meeting places between 2 or more bones; they give the skeleton mobility and hold it together | joints (articulatiors) |
| body movement happen when muscles contract __________ __________, moving one bone toward another | across joints |
| attach bones to bones | ligaments |
| attach muscles to bones | tendons |
| What is the functional classification of joints based on? | what they do and how much movement they allow |
| less movable the joint = ____________ stable it is | more |
| non-moving joints; ex: the part of the skull that protects the brain = cranium | synarthroses |
| slightly moving joints; ex. where pubic bones meet in the pelvis | amphiarthroses |
| freely moving joints; ex. like knee and elbow, mainly in our limbs | diarthroses |
| What is the structural classification of joints based on? | on what binds the bones together in the joint and if a cavity is present |
| connect bones with the collagen fibers of dense connective tissue, mostly immovable; ex. bones in the skull, fibula and tibia, teeth embedded in their sockets | fibrous joints |
| bones in the skull are held together by fibrous joints called | sutures |
| fibula and tibia in your lower leg are held together by ligaments only by fibrous joints called | syndesmoses |
| the way teeth are embedded in their sockets by fibrous joints called | gomphoses |
| connect bones with cartilage and can be rigid but also slightly movable; ex. hyaline cartilage between sternum and first rib, shock absorbers between vertebrae, and pubic symphysis joint | cartilaginous joints |
| an immovable joint made of a bar/plate of hyaline cartilage between sternum and first rib called | synchondrosis |
| a slightly movable joint made of fibrocartilaginous intervertebral discs that act as a shock absorber between vertebrae called | symphysis |
| connect bones with dense connective tissue AND a fluid filled joint cavity; allows them to be freely movable (all are diarthroses) | synovial joints |
| covers the opposing bone surfaces | articular cartilage |
| greasy fluid to avoid friction and promote gliding and movement | joint cavity |
| encloses the cavity | fibrous joint cavity |
| in the cavity that acts as a lubricant | synovial fluid |
| bandlike _______________ for reinforcement | ligaments |
| in the joint capsule and synovial membrane | sensory nerve fibers and blood vessels |
| also known as "plane" joint; allow gliding movements; when one flat bone surface glides or slips over another (back and forth or side to side); ex. intercarpal (wrist) and intertarsal (ankle) joints | gliding |
| only moves in one direction; allow angular movements like flexion and extension; ex. elbow and interphalangeal (fingers) joints and knee | hinge |
| bending in a way that decreases the angle of the joint, so the articulating bones get closer | flexion |
| reverse of flexion | extension |
| going beyond the anatomical position | hyperextension |
| allow rotation as well as twisting movements back and forth; ex. where humerus meets radius and ulna at the elbow | pivot |
| turn/twist forward | supination |
| turn/twist backward | pronation |
| like a pedestal with a joint on top; allows movements like flexion/extension, as well as abduction and adduction; ex. in the wrist | condylar |
| "Moving away"; moving a limb away from the median plane, along the frontal plane | abduction |
| "Moving toward"; opposite of abduction | adduction |
| allows opposition movements as well as flexion/extension, abduction/adduction; ex. thumb joints | saddle |
| lots of maneuverability; allow rotational movements, abduction/adduction, flexion/extension; ex. shoulder and hip joints | ball and socket |
| turning of the bone around its own long axis | rotation |
| moving limb in a circle; ex. making circles with arms | circumduction |
| lifting (then lowering) a body part superiorly; ex. shrugging your shoulders and jaw dropping | elevation and depression |
| ex. sticking jaw out (to make an under bite) and back in | protraction and retraction |
| lifting foot up and down at the ankle | dorsiflexion and planter flexion |
| turning the foot towards the midline of the body vs. turning away from the midline of the body | inversion and eueration |
| Bones can't move without ______________ that connect them and the _________________ that stretch over those joints | joints; muscles |
| movement occurs when muscles _____________ | contract |
| causes a change in the length of the muscles; ex. lifting a box or doing push-ups | isotonic |
| no change in length; ex. standing with good posture or doing a plank | isometric |
| the movable bone during a muscle contraction | insertion |
| the bone that moves less or not at all; ex. in a bicep curl, the scapula | origin |
