Joints TB Flashcards
joint btw the two pubic bones
symphysis
summary joints
a fibrous joint that unites the bones of the skull
suture
convex, oval projection of one bone fits into oval depression of another bone: permits movement in 2 axes
condyloid joint
menisci are fluid filled sacs locates outside of joint cavity to ease friction btw bones and softer tissue T>F?
FALSE
summary joints
increase in angle between bones
extension
figure questions
movement of forearm to turn palm anteriorly
supination
rounded/ pointed surface of one bone art w/ a ring formed by another bone and a ligament: allows rotation around its own axis
pivot joint
convex surface of one bone articulates with concave surface of another bone; permits flexion and exteion
hinge joint
the surgical procedure in which severely damaged joint is replaced with artificial joint is known as
anthroplasty
articulating bone surfaces are flat or slightly curved; permit gliding movement
plane joint
which of the following joints could be classified functionally as synarthrosis? 1. syndesmosis 2. symphysis 3. synovial 4. gomphosis 5. suture
- gomphosis 5. suture
the epiphyseal (growth) plate
synchondrosis
bone revolves around its own longitudinal axis
rotation
the most common degenerative joint disease in elderly often caused by wear and tear is
osteoarthritis
chewing your food involves 1. flexion 2. extension 3. hyperextension 4. elevation 5. depression
4, 5
a pont of contact between two bones, bone and cart, bone and teeth is called a
joint/ articulation. arthrosis
joint with a cavity between bone: diathrosis
synovial
modified condyloid joint where art bones resemble rider sitting on saddle
saddle joint
synovial fluid becomes more viscous (thicker) as movement of joint increases
false
synovial fluid functions 1. abs shock at joints 2. lubricate joints 3. form blood clot in joint injury 4. supp. o2 and nutrients to chondrocytes 5. provide phagocytes to remove debris from jointa
1,2,,4,5
which of following statements are true concerning a synovial joint? 1. the bones at SJ are covered by mucous membrane 2. the articular capsule surrounds the 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
shrugging shoulders involve flexion and extension
false
a fibrous joint between tibia and fibula: an amphiathrosis
syndesmosis
the articulation between bone and teecth
gomphosis
ball shaped surface of one bone art with cupcake depression of another bone, permits largest degree of movement in three axes
ball and socket joint
which of following are structural classifications of joint? 1. amphiarthrosis 2. cartiligenous 3. synovial 4. synarthrosis 5. fibrous
- ampiarthrosis 4. synarthrosis
which of following keep art surfaces of synovial joints in contact and affect range of motion/ 1. estruture or shape of the art bones 2. strength and tension of joint ligaments 3. arrangement and tension of muscles 4. lack of use 5. contact of soft parts
1,2,3,4,5
bony joint
synostosis
