Joints and Movement Flashcards
Which of these joints is not matched with the correct joint type?
a. parietal bone to occipital bone—suture
b. between the hipbones—symphysis
c. humerus and scapula—synovial
d. shafts of the radius and ulna—synchondrosis
e. teeth in alveolar process—gomphosis
shafts of the radius and ulna—synchondrosis
Which type of joint is the most movable?
a. sutures
b. syndesmoses
c. symphyses
d. synovial
e. gomphoses
synovial
The intervertebral disks are examples of
symphyses
Joints containing hyaline cartilage are called _____ , and joints containing fibrocartilage are called _____.
synchondroses, symphyses
The inability to produce the fluid that keeps most joints moist would likely be caused by a disorder of the
synovial membrane
Assume that a sharp object penetrated a synovial joint. Given these structures:
(1) tendon or muscle
(2) ligament
(3) articular cartilage
(4) fibrous capsule (of joint capsule)
(5) skin
(6) synovial membrane (of joint capsule)
Choose the order in which they would most likely be penetrated.
5,1,2,4,6,3
Which of these joints is correctly matched with the type of joint?
a. atlas to occipital condyle—pivot
b. tarsal bones to metatarsal bones—saddle
c. femur to hipbone—ellipsoid
d. tibia to talus—hinge
e. scapula to humerus—plane
tibia to talus—hinge
When you grasp a doorknob, what movement of your forearm is necessary to unlatch the door—that is, to turn the knob in a clockwise direction? (Assume using the right hand.)
supination
After the door is unlatched, what movement of the elbow is necessary to open it? (Assume the door opens in and you are on the inside.)
flexion
After the door is unlatched, what movement of the shoulder is necessary to open it? (Assume the door opens in and you are on the inside.)
extension
When grasping a doorknob, the thumb and finger undergo
opposition
A runner notices that the lateral side of her right shoe is wearing much more than the lateral side of her left shoe. This could mean that her right foot undergoes more _____ than her left foot.
inversion
For a ballet dancer to stand on her toes, her feet must
plantar flex
A meniscus is found in the
knee joint
A lip (labrum) of fibrocartilage deepens the joint cavity of the
shoulder joint
What joints has a tendon inside the joint cavity?
shoulder joint
Which of these structures help stabilize the shoulder joint?
a. rotator cuff muscles
b. cruciate ligaments
c. medial and lateral collateral ligaments
d. articular disks
e. All of these are correct.
rotator cuff muscles
Bursitis of the subacromial bursa could result from
a. flexing the wrist.
b. kneeling.
c. overusing the shoulder joint.
d. running a long distance.
e. extending the elbow.
overusing the shoulder joint
Which of these events does not occur with the aging of joints?
a. decrease in production of new cartilage matrix
b. decline in synovial fluid production
c. stretching of ligaments and tendons and increase in range of motion
d. weakening of muscles
e. increase in protein cross-linking in tissues
stretching of ligaments and tendons and increase in range of motion
