Unit 4 Movement

Question 1

Adduction

Answer 1

Movement toward the midline off the body

Question 2

Articular Cartilage

Answer 2

Hyaline cartilage attached to the articular bone surface

Question 3

Articulation

Answer 3

The action or manner in which the parts come together at a joint

Question 4

Ball and socket joint

Answer 4

An articulation (as the hip joint) in which the rounded head of one bone fits into a cuplike cavity of the other and adits movement in any direction.

Question 5

Abduction

Answer 5

Movement away from the midline of the body

Question 6

Cartilage

Answer 6

A usually translucent somewhat elastic tissue that composes most of the skeleton of vertebrate embryos and except for a small number of structures (as some joints, respiratory passages, and the external ear) is replaced by bone during ossification in the higher vertebrates.

Question 7

Circumduction

Answer 7

A movement at a synovial joint in which the distal end of the bone moves in a circle while the proximal end remains relatively stable

Question 8

Dorsiflexion

Answer 8

Bending the foot in the direction of the dorsum (upper surface)

Question 9

Extension

Answer 9

An unbending movement around a joint in a limb (as the knee or elbow) that increases the angle between the bones of the limb at the joint

Question 10

Flexion

Answer 10

A bending movement around a joint in a limb (as the knee or elbow) that decreases the angle between the bones of the limb at the joint

Question 11

Goniometer

Answer 11

An instrument of measuring angles (as of a joint or the skull)

Question 12

Hinge Joint

Answer 12

Joint between bones (as at the elbow or Knee) that permits motion in only one plane

Question 13

Hyaline cartilage

Answer 13

Translucent bluish white cartilage consisting of cells embedded in an apparently homogeneous matrix, present in joints and respiratory passages, and forming most of the fetal skeleton

Question 14

Joint

Answer 14

The point of contact between elements of an animal skeleton whether movable or rigidly fixed together with the surrounding and supporting parts (as membranes, tendons, or ligaments)

Question 15

Ligament

Answer 15

Dense regular connective tissue that attaches bone to bone

Question 16

Plantar Flexion

Answer 16

Bending the foot in the direction of the planar surface

Question 17

Range Of Motion

Answer 17

The range through which a joint can be moved

Question 18

Rotation

Answer 18

Moving a bone around its own axis, with no other movement

Question 19

Synovial cavity

Answer 19

The space between the articulation bones of a synovial joint, filled with synovial fluid. Also called the joint cavity

Question 20

Synovial fluid

Answer 20

Secretion of synovial membranes that lubricates joints and nourishes articular cartilage

Question 21

Synovial joint

Answer 21

A fully moveable joint in which the synovial(joint) cavity is present between the two articulating bones

Question 22

Tendon

Answer 22

a white fibrous cord of dense regular connective tissue that attaches muscle to bone
