when gently pulling the leg anteriorly, what was the amount of motion and the ligament being assessed?
-amount of motion= minimal -ACl was being tested
when gently pulling the leg posteriorly, what was the amount of motion and the ligament being assessed?
-amount of motion= minimal -PCL was being tested
T or F: Bursae discs improve the fit between two bones in a synovial joint
Articular
amphiarthrosis
Joint that allows some motion
T or F: the articulating ends of the bones in a synovial joint are covered by an articular cartilage
True
T or F: the joint capsule of a synovial joint is lined with a synovial membrane
True
saddle
a joint where the articular surfaces fit together as a saddle
flexion
a motion that decreases the angle between two bones
extension
a motion that increases the angle between two bones
cartilaginous
amphiarthrotic joints consisting of bones united by cartilage rather than fibrous connective tissue
condyloid
an oval articular surface fits into an oval depression in another bone
T or F: articular discs provide a smooth, nearly frictionless surface for articulation
articular cartilage
T or F: fluid-filled sacs called ligaments often lie between tendons and the joint capsule of a synovial joint
bursae
synovial
diarthrotic joints consisting of two bones whose articular ends are covered with hyaline cartilage; the bones are separated by a fluid-filled joint cavity
plantarflexion
downward movement of the foot (pointing toes)
plane
flat articular surfaces that allow gliding motion
diarthrosis
freely moveable joint
synarthrosis
immovable joint
synovial joints are surrounded by a/an..
joint capsule
an amphiarthrosis is defined as a
joint that allows some motion
hinge
joints that allows motion in one plane only
elevation
lifting a body part superiorly
rotation
movement of a bone about its own axis
abduction
movement of a limb away from the midline of the body
adduction
movement of a limb toward the midline of the body
circumduction
movement of a part in a cone-shaped radius
opposition
movement of the thumb medially across the surface of the palm
depression
moving a body part inferiorly
which of the following correctly describes a pivot joint
one bone rotates around another bone
the main function of a fibrous joint is to
provide stability between two bones
supination
rotating the radius around the ulna so the palm faces anteriorly
pronation
rotating the radius around the ulna so the palm faces posteriorly
fibrous
synarthrotic joints consisting of bones joined by short connective tissue fibers
synovial joints are filled with...
synovial fluid
which of the following describes a hinge joint correctly?
the convex articular surface of one bones fits into a concave articular surface of another bone
pivot
the end of one bone fits into a "ring" of bone or tissue of another bone, allowing rotation of the bone about its own axis
ball and socket
the round head of one bone fits into the socket of another
eversion
turning the sole of the foot laterally
inversion
turning the sole of the foot medially
dorsiflexion
upward movement of the foot so it approaches the shin
