Answer 19

Scaphoid Lunate Triquetrum Pisiform Trapezium Trapezoid Capitate Hamate

Answer 20

calcaneus, talus, navicular, cuboid, medial cuneiform, intermediate cuneiform, lateral cuneiform

Answer 21

transverse, linear, oblique nondisplaced, oblique displaced, spiral, greenstick, comminuted

Answer 22

also known as osteophytes, occur when the body grows small projections on the edges of bones

Answer 23

common cause of heel pain. -inflammation of the plantar fascia - walking can be painful

Answer 24

Increased activity of osteoclasts cause a break down bone, bones become more fragile The spongy bone especially becomes more porous.

Answer 25

an autoimmune disease which causes joint stiffness and bone deformity

Answer 26

Functional junctions between bones Allow the body to move and change shape when muscles contract

Answer 27

Lie between bones that closely contact each other Thin layer of dense connective tissue (sutures of the bones in the skull) No or very limited movement

Answer 28

Hyaline cartilage connects the bones Also provides shock absorption Allow limited movement Example: joints between the vertebrae of the vertebral column

Answer 29

Most joints in the body Allow free movement of the bones Articular ends of the bones are covered in cartilage and surrounded by a capsule of dense connective tissue Some have flattened pads of cartilage called menisci Some have fluid filled sacs called bursae

Answer 30

Condyloid Joints Oval shaped condyle of one bone fits into the cavity of another Permits movement in a variety of planes but not rotational Example: Metacarpals and phalanges 6. Gliding Joints Almost flat or slightly curved Allow sliding and twisting Examples: ankles and wrists

Answer 31

bending parts at a joint so that the angle between them decreases and the parts come together

Answer 32

Straightening parts at a joint so that the angle between them increases and the parts move further apart

Answer 33

bending the foot at the ankle toward the shin

Answer 34

bending the foot at the ankle toward the sole

Answer 35

excess extension of the parts at a joint beyond the anatomical position

Answer 36

moving a part away from the midline

Answer 37

moving a part toward the midline

Answer 38

moving a part around an axis

Answer 39

moving a part so that its end follows a circular path

Answer 40

palms down

Answer 41

turning the foot so that the sole faces laterally

Answer 42

turning the foot so that the sole faces medially

Answer 43

moving a part backward

Answer 44

moving a part forward

Answer 45

raising a part

Answer 46

lowering a part
