|---|---|---|---|---|---|
| another name for synovial joints? | show 🗑
|
||||
| show | the most anatomically complex joint & the most common in the body, bones are separated by a joint cavity.
🗑
|
||||
| show | it is a remarkable joint: it is self-lubricating, almost frictionless, able to bear heavy loads & can withstand compression while executing smooth & precise movements
🗑
|
||||
| movement in synovial joints? | show 🗑
|
||||
| what are the main components of a basic synovial joint? | show 🗑
|
||||
| articular surfaces/discs | show 🗑
|
||||
| show | a narrow space that separates the facing articular surfaces of 2 bones.
🗑
|
||||
| joint fluid | show 🗑
|
||||
| show | a complex mixture of hyaluronic acid (secreted by the modified CT cells in synovial membrane), proteins & fats (provided by the blood filtrate) & phagocytes (which clean up tissue debris from joint cavity)
🗑
|
||||
| how much synovial fluid is in the knee? | show 🗑
|
||||
| joint capsule | show 🗑
|
||||
| fibrous capsule | show 🗑
|
||||
| synovial membrane | show 🗑
|
||||
| role of ligaments in a synovial joint? | show 🗑
|
||||
| show | in certain synovial joints, the synovial membrane may extend as a pocket or sac filled with synovial fluid. This provides a fluid-filled cushion b/w structures (i.e. b/w adjacent muscles, tendon & bone, bone & skin, etc)
🗑
|
||||
| Tendon sheaths | show 🗑
|
||||
| blood supply in a synovial joint? (prevalence, location and function?) | show 🗑
|
||||
| nerves in a synovial joint? (prevalence & location?) | show 🗑
|
||||
| why do we need nerves in a synovial joint? | show 🗑
|
||||
| proprioception | show 🗑
|
||||
| show | by the shape of the adjoining articular surfaces
🗑
|
||||
| show | motion between bones occurs in only one plane
🗑
|
||||
| show | motion between bones occurs in 2 planes
🗑
|
||||
| show | motion is possible in all three planes of space
🗑
|
||||
| show | hinge joint & pivot joint
🗑
|
||||
| what are the biaxial synovial joints? | show 🗑
|
||||
| what is the only multiaxial synovial joint? | show 🗑
|
||||
| hinge joint (definition and mobility) | show 🗑
|
||||
| show | elbow, knee, interphalangeal joints
🗑
|
||||
| pivot joint (definition & mobility?) | show 🗑
|
||||
| show | axis to atlas, (rotates back and forth) radioulnar joint of elbow (twist forearm back and forth)
🗑
|
||||
| show | 2 flat surfaces gliding across eachother
(biaxial)
🗑
|
||||
| examples of plane/gliding joints? | show 🗑
|
||||
| condyloid/ellipsoid joint (definition and mobility?) | show 🗑
|
||||
| examples of condyloid joint? | show 🗑
|
||||
| show | two concave surfaces oriented at right angles to eachother
(biaxial)
🗑
|
||||
| show | carpometacarpal joint of thumb (allows twiddling of thumbs)
🗑
|
||||
| ball-and-socket joint? (definition & mobility?) | show 🗑
|
||||
| convex cylinder of one bone articulates with corresponding concavity of another bone? | show 🗑
|
||||
| relatively cylindrical bony process that rotates within a ring composed partly of bone and partly of ligament? | show 🗑
|
||||
| 2 flat surfaces gliding across eachother? | show 🗑
|
||||
| show | condyloid/ellipsoid joint
🗑
|
||||
| two concave surfaces oriented at right angles to eachother? | show 🗑

||||
| a ball articulating with a socket? | show 🗑
|
||||
| show | 8 carpals (dots), four metacarpals (just fingers, ring finger is between carpals). five phalanges. saddle = carpometacarpal joint of thumb (circle b/w carpal & phalange of thumb). condyloid = metacarpophalangeal joints (circle all 4 b/w meta & phalange)

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
