Question 1

extension

Answer 1

An increase in the angle between two articulating bones; the opposite of flexion

Question 2

rheumatism

Answer 2

A general term used to describe pain in muscles, tendons, bones, or joints.

Question 3

symphysis

Answer 3

A fibrous amphiarthrosis, such as that between adjacent vertebrae or between the pubic bones of the coxal bones.

Question 4

articular capsule

Answer 4

The dense collagen fiber sleeve that surrounds a joint and provides protection and stabilization; also called joint capsule.

Question 5

articulation

Answer 5

a joint

Question 6

amphiarthrosis

Answer 6

A joint (articulation) that permits a small degree of independent movement; see interosseous membrane (8) and pubic symphysis.

Question 7

nucleus pulposus

Answer 7

The gelatinous central region of an intervertebral disc.

Question 8

ligament

Answer 8

A dense band of connective tissue fibers that attaches one bone to another.

Question 9

articular cartilage

Answer 9

The cartilage pad that covers the surface of a bone inside a joint cavity.

Question 10

circumduction

Answer 10

A movement at a synovial joint in which the distal end of the bone moves in a circular direction, but the shaft does not rotate.

Question 11

eversion

Answer 11

a turning outward

Question 12

flexion

Answer 12

A movement that decreases the angle between two articulating bones; the opposite of extension.

Question 13

bursa

Answer 13

A small sac filled with synovial fluid that cushions adjacent structures and reduces friction.

Question 14

inversion

Answer 14

a turning inward

Question 15

synovial fluid

Answer 15

The substance secreted by synovial membranes that lubricates joints.

Question 16

intervertebral disc

Answer 16

A fibrocartilage pad between the bodies of successive vertebrae that absorbs shocks.

Question 17

diarthrosis

Answer 17

a synovial joint

Question 18

adduction

Answer 18

Movement toward the axis or midline of the body, as viewed in the anatomical position.

Question 19

joint

Answer 19

An area where adjacent bones interact; also called articulation

Question 20

suture

Answer 20

A fibrous joint between flat bones of the skull

Question 21

meniscus

Answer 21

A fibrocartilage pad between opposing surfaces in a joint

Question 22

dorsiflexion

Answer 22

Upward movement of the foot through flexion at the ankle

Question 23

supination

Answer 23

The rotation of the forearm such that the palm faces anteriorly.

Question 24

anulus

Answer 24

A cartilage or bone shaped like a ring; also spelled annulus

Question 25

pronation

Answer 25

The rotation of the forearm that makes the palm face posteriorly.

Question 26

synovial joint

Answer 26

A freely movable joint where the opposing bone surfaces are separated by synovial fluid; a diarthrosis.

Question 27

abduction

Answer 27

Movement away from the midline of the body, as viewed in the anatomical position.
