8-C Flashcards
A sprain is the forcible wrenching or twisting of a joint that stretches or tears its ligaments but does not dislocate the bones.
true or false
True
occurs when the ligaments are stressed beyond their normal capacity.
Sprain
a stretched or partially torn muscle or muscle and tendon.
Strain
causes Lyme disease
Borrelia burgdorferi
The bacteria are transmitted to humans mainly by deer
Lyme Disease
knee joint is also called
tibiofemoral joint
is the largest and most complex joint of the body.
Knee joint
all-and-socket joint formed by the head of the humerus and the glenoid cavity of the scapula.
Shoulder Joint
Shoulder Joint is also called
humeroscapular or glenohumeral joint
elbow joint is what kind of joint?
Hinge joint
a hinge joint formed by the trochlea and capitulum of the humerus, the trochlear notch of the ulna, and the head of the radius.
Elbow joint
temporomandibular joint (TMJ) is a combination of
hinge and plane joint
TMJ means?
temporomandibular joint
All other skull joints are sutures and therefore movable
True or false
False
All other skull joints are sutures and therefore immovable or slightly movable.
It is called sellar joint
Saddle joints
Carpometacarpal joint: trapezium (carpal) to metacarpal-1 (thumb) is what type of joint?
Saddle joint
Rounded surface with ring formed by bone and ligament
pivot joint
Trochoid joint is also called?
Pivot joint
Condyloid joint is also called
Ellipsoidal joint
Convex oval surface to concave oval surface
Condyloid
produce an angular, opening-andclosing motion like that of a hinged door
Hinge joints
Hinge joint can also be called as
Ginglymus joint
Planar joints
- Articulating surfaces flat or slightly curved
- Permit back-and-forth and side-to-side movements between the flat surfaces of bones, but they may also rotate against one another
Movement of the thumb at the carpometacarpal joint in which the thumb moves across the palm to touch the tips of the fingers on the same hand
Opposition
Pronation
Movement of forearm so palms face backward or downward
Movement of forearm so palms face forward or upward
Supination
Bend foot toward plantar surface (“stand on toes”)
Plantar flexion
Bend foot toward dorsum (“stand on heels”)
Dorsiflexion
Move soles laterally
Eversion
Move soles medially
Inversion
Synovial joints are divided into six categories based on type of movement
True or false
True
Synovial joints are divided into six categories based on type of movement:
plane,
hinge,
pivot,
condyloid,
saddle, and
ball-and-socket.
Movement upward
Elevation
Movement downward
Open mouth to depress the mandible
Depression
Closing mouth at the TMJ
Elevation
Movement backward into anatomical position
Retraction
Protraction
Movement backward
Abduction and adduction usually occur along the dorsal plane
True or false
False
Abduction and adduction usually occur along the FRONTAL plane
Bending beyond 180o degrees, such as moving humerus backwards behind anatomical position
Hyperextension
Extension
Increase in angle between articulating bones
Flexion
Deccrease in angle between articulating bones
Consist of side-to-side and back-and-forth motions.
Gliding movement
space containing fluid; allows considerable joint movement
Synovial cavity
a layer of hyaline cartilage that covers ends of bones, absorbs shock and reduces friction
Articular Cartilage
unites articulating bones;
Articular Capsule
articulation or arthrosis is?
Also called a joint
is a point of contact between two or more bones, between cartilage and bones, or between teeth and bones.
Joint
Immovable-
slightly movable-
and freely movable-
Synarthrosis
Arthrosis
Diarthrosis
