A&P CHAPTER 8: ARTICULATIONS Flashcards
JOINTS ARE ALSO KNOWN AS WHAT
ARTICULATIONS
SYNARTHROTIC JOINT
IMMOVABLE
AMPHIARTHROSIS
SLIGHT MOVEMENT
DIARTHROSIS
FREE MOVEMENT
SUTURES
SYNARTHROTIC JOINT
OCCUR ONLY BETWEEN SKULL BONES
ONLY EXAMPLE OF GOMPHOSES IN BODY
TEETH
SYNOVIAL JOINTS
ALLOW FREE MOVEMENT (DIARTHROTIC)
OUTER LAYER OF LIGAMENTS
INNER LAYER OF SYNOVIAL MEMBRANE THAT SECRETES SYNOVIAL FLUID TO LUBRICATE JOINTS
6 CHARACTERISTICS OF SYNOVIAL JOINTS
ARTICULAR CARTILAGE
ARTICULAR CAVITY
ARTICULAR CAPSULE
SYNOVIAL FLUID
REINFORCING LIGAMENTS
NERVES AND BLOOD VESSELS
BURSAE
FLAT FIBROUS SACS WITH SYNOVIAL MEMBRANES LINING THEM
WHERE BONES, MUSCLES, ETC RUB TOGETHER
TENDON SHEATH
LENGTHENED BURSAE WRAPPING TOTALLY AROUND A TENDON SUBJECTED TO FRICTION
GLIDING JOINT
NONAXIAL LINEAR GLIDING AND FLAT SURFACES (PATELLA)
HINGE JOINT
UNIAXIAL INVOLVED FLEXION AND EXTENSION (ELBOW)
PIVOT JOINT
UNIAXIAL ROTATION AROUND A VERTICAL AXIS
ELLIPSOIDAL JOINTS
BIAXIAL MOVEMENT INVOLVING ADDUCTION AND ABDUCTION (METACARPALS)
SADDLE JOINTS
BIAXIAL MOVEMENT OF FLEXION/EXTENSION AND ADDUCTION/ABDUCTION (THUMBS)
BALL-AND-SOCKET JOINT
MULTIAXIAL MOVEMENT INVOLVING ROTATION, ADDUCTION/ABDUCTION, FLEXION/EXTENSION (SHOULDER AND HIP)
SPRAIN
STRETCHING OR TEARING OF LIGAMENTS
DISLOCATION
AKA LUXATION
BONES FORCED OUT OF ALIGNMENT
ARTHRITIS
INFLAMMATORY/DEGENERATIVE DISEASES THAT DAMAGE THE JOINTS
RHEUMATOID ARTHRITIS
AUTOIMMUNE DISORDER AFFECTING HANDS CAUSING PAIN, STIFFNESS, DEFORMITY
GOUTY ARTHRITIS
ACCUMULATION OF URIC ACID
MOSTLY AFFECTS BIG TOE SOMETIMES FINGERS
OSTEOARTHRITIS
MOST COMMON TYPE OF ARTHRITIS
DEGENERATION OF JOINTS FROM ENZYMATIC ACTIVITY
MORE CARTILAGE IS DESTROYED THAN CAN BE REPLACED
BURSITIS
INFLAMMATION OF BURSAE CAUSED BY TRAUMA OR FRICTION
TENDONITIS
INFLAMMATION OF TENDON SHEATHS CAUSED BY EXCESSIVE WEAR
LYME DISEASE
CAUSED BY SPIROCHETE BACTERIA TRANSMITTED BY TICKS
CAUSES JOINT PAIN, ARTHRITIS, RASH, FLU, IMPAIRED COGNITIVE FUNCTION
