Joints Summary Flashcards
Diarthrosis
free moving
Ampiarthrosis
slight movement
Synarthrosis
little to no movement
What are the features of fibrous joints?
collagen fibers, no joint cavity, synarthrosis
Sutures are are what type of joint?
fibrous joints
Gomphoses are are what time of joint?
fibrous joints
Syndesmosis are what type of joint?
fibrous joints
Cartilaginous joints are what type of movement?
amphiarthrosis
What are synchondrosis joints made of and found in?
hyaline cartilage (epiphyseal plate)
What are symphysis joints made of and found in?
fibrocartilage (intervertebral disc, pubic symphyses)
What are the features of synovial joints?
articular cartilage, has joint cavity, diarthrotic (tendons, bursa, joint capsule, synovial fluid, fibrocartilage, movement)
Monoaxial
one plane of movement (elbow)
Biaxial
two planes of movement (metacarpophalangeal)
Multiaxial
three planes of movement (shoulder)
Ball-and-socket joint
head and cup-like socket (hip), multiaxial
Condyloid joint
one bone fits in a depression (radoiocarpal), biaxial
Saddle joint
saddle like fit of two bones (trapeziometacarpal), biaxial
Plane joint
bones slide or glide (intertarsal), biaxial
Hinge joint
fits into each other (elbow), monoaxial
Pivot joint
ring like ligament (radioulnar), monoaxial
Anatomical position
zero position
Flexion
decreases the angle of a joint
Extension
increases the angle of a joint
Hyperextension
extension beyond anatomical position/zero point
Abduction
movement away from the midline
Adduction
movement toward the midline
Elevation
raising a body part
Depression
lowering a body part
Protraction
moving a body part forward and parallel to the ground
Retraction
moving a body part backward and parallel to the ground
Circumduction
circular movement of a limb at the far end
Inversion
turning the sole of the foot inward
Eversion
turning the sole of the foot outward
Medial rotation
rotation toward the midline
Lateral rotation
rotation away from the midline
Supination
palm up
Pronation
palm down
Opposition
touching the thumb to any other finger
Ulnar deviation
movement of the wrist towards the ulna (pinky) or medial side
Radial deviation
movement of the wrist towards the radius (thumb) or lateral side
Plantar flexion
bends the foot downward at the ankle
Dorsiflexion
bends the foot upward at the ankle
Lateral excursion
right or left movement from the zero position
Sprain
stretching or tearing of ligaments
Dislocation
displacement of a bone from its joint
Bursitis
inflammation of a bursa sac
Tendonitis
inflammation of a tendon
Arthritis
painful inflammation and stiffness of the joints
Rheumatoid arthritis (RA)
chronic systemic disease characterized by autoimmune inflammatory changes in the connective tissue throughout the body
Gout arthritis
metabolic disease caused by the accumulation of uric acid crystals in the blood
Osteoarthritis
wear and tear arthritis
