Joints Flashcards
(31 cards)
Joint
An articulation or arthrosis
* between bones
* between cartilage and bone
* between teeth and bone
Arthrology
The study of the joints, joint diseases, and treatments
Kinesiology
Study of movement of the human body
Joints with no movement (inflexible) are STRONGER than those joints that move freely ( flexible)
Loosely fitted joints yields GREATER movement and are more prone to displacement
A point of contact between two bones, between bone and cartilage, or between bone and teeth is called a(n):
Articulation
The surgical procedure in which a severely damaged joint is replaced with an artificial joint is known as:
Arthroplasty
Menisci are fluid-filled sacs located outside of the joint cavity to ease friction between bones and softer tissue.
FALSE
Shrugging your shoulders involves flexion and extension.
FALSE
Synovial fluid becomes more viscous (thicker) as movement at the joint increases.
FALSE
Which of the following are structural classifications of joints?
1 Amphiarthrosis
2 Cartilaginous
3 Synovial
4 Synarthrosis
5 Fibrous
2, 3, and 5
Which of the following joints could be classified functionally as synarthroses?
4 and 5
The most common degenerative joint disease in the elderly, often caused by wear-and-tear, is
Osteoarthritis
Chewing your food involves…
Elevation and Depression
Synovial fluid functions to:
1 Absorb shocks at joints
2 Lubricate joints
3 Form a blood clot in a joint injury
4 Supply oxygen and nutrients to chondrocytes
5 Provide phagocytes to remove debris from joints
1, 2, 4 and 5
Which of the following statements are true concerning a synovial joint?
1 The bones at a synovial joint are covered by a mucous membrane.
2 The articular capsule surrounds a synovial joint, encloses the synovial cavity, and unites the articulating bones.
3 The fibrous membrane of the articular capsule permits considerable movement at a joint.
4 The tensile strength of the fibrous membrane helps prevent bones from disarticulating.
5 All synovial joints contain a fibrous membrane.
2, 3, 4, and 5
Which of the following keep the articular surfaces of synovial joints in contact and affect range of motion?
1 Structure or shape of the articulating bones
2 Strength and tension of the joint ligaments
3 Arrangement and tension of muscles
4 Lack of use
5 Contact of soft parts
1,2,3,4 and 5
The joint between the two pubic bones is a smphysis
TRUE
A fibrous joint between the tibia and fibula (a type of amphiarthrosis) is a suture.
FALSE
A type of joint that allows rotation around its own and is constructed with a rounded or pointed surface of one bone that articulates with a ring formed by another bone and a ligament is a:
Pivot joint
The glenohumeral (shoulder) joints are the only ball-and-socket joints in the body
FALSE
Movement of a body part anteriorly in the transverse plane is:
Protraction
An increase in the angle between two bones is known as:
Extension
Pain in a joint
Arthralgia
A movement at a synovial joint in which the distal end of a bone moves in a circle while the proximal end remains relatively stable.
Circumduction
