Question 1

Symphysis

Answer 1

Surfaces of bones are covered by hyaline cartilage. Limited movement. Ex: joints between vertebra.

Question 2

Pronation

Answer 2

Rotation of the forearm so the palm is downward.

Question 3

Supination

Answer 3

Rotation of the forearm so the palm is upward.

Question 4

Circumduction

Answer 4

Moving apart so that it’s end follows a circular path.

Question 5

Rotation

Answer 5

Moving around the axis.

Question 6

Addiction

Answer 6

Moving closer to the midline.

Question 7

Abduction

Answer 7

Moving away from the midline.

Question 8

Plantar flexion

Answer 8

Movement at the ankle, brings foot further away from the shin.

Question 9

Dorsiflexion

Answer 9

Movement at the ankle. Brings foot closer to the shin.

Question 10

Hyperextension

Answer 10

Extended beyond the anatomical position.

Question 11

Extension

Answer 11

Moving apart at a joint, the angles go further apart.

Question 12

Flexion

Answer 12

Bending parts at a joint, so the angle comes closer together.

Question 13

Saddle

Answer 13

Both concave and convex regions, one bone fits the complementary surface of another.

Question 14

Pivot

Answer 14

Cylindrical surface of ones bones articulates with ring of bone and ligament. Rotates. Ex: joints between proximal ends.

Question 15

Hinge

Answer 15

Convex surface of one bone articulates with concave surface of another. Extension. Ex: elbow.

Question 16

Plane

Answer 16

Surfaces are nearly flat or slightly curved. May slide and twist. Ex: wrist or ankle.

Question 17

Condylar

Answer 17

Oval shaped condolences of one bone that fits with elliptical cavity of another. Can move but not full rotate. Ex: joints between fingers.

Question 18

Ball - and - socket

Answer 18

Head of one bone articulates with the cup shaped socket of another. Movement in all rotations. Ex: shoulder and hip.

Question 19

Synovial

Answer 19

Ends of bones surrounded by joint caps. Covered by hyaline cartilage and separated by synovial fluid.

Question 20

Synchondrosis

Answer 20

Bones united by hyaline cartilage. Ex: joints between the ribs.

Question 21

Cartilage joints

Answer 21

Bones held together by hyaline cartilage.

Question 22

Gomphosis

Answer 22

Cone shaped process in bony socket. Ex: tooth root.

Question 23

Structure

Answer 23

Flat bones weaved together by ligaments.

Question 24

Syndesmosis

Answer 24

Situated between bone ligaments. Joint is flexible and may be twisted.

Question 25

Fibrous joints

Answer 25

Bones held together by a thin layer.

Question 26

Cartilaginous joints

Answer 26

Hyaline cartilage of fibrocartilage connects the bones.

Question 27

Articular cartilage

Answer 27

Resists wear and minimizes friction when it is compressed as the joint moves.

Question 28

Synovial joints

Answer 28

Most joints are this. Allow free movement structure is more complex.

Question 29

Synchondrosis

Answer 29

Bands of hyaline cartilage unite the bone. Many are temporary and disappear during growth.

Question 30

Symphysis

Answer 30

Covered by a thin layer of hyaline cartilage bones connected by a pad of fibrocartilage. Limited movement.

Question 31

Fibrous joints

Answer 31

A dense connective tissue holding together many collagen fibers. Found in between bones close in contact.

Question 32

Joint capsule

Answer 32

Two distinct layers. Holds joints together.

Question 33

Syndesmosis

Answer 33

The bones are bound by a sheet or bundle of dense tissue. Flexible and may be twisted. Joints may permit slight movement. Found between the tibia and fibula.

Question 34

Sutures

Answer 34

Only found between flat bones of the skull were adjacent. Bones grow together. Allow the skull to change shape slightly during child birth.

Question 35

Gomphosis

Answer 35

A joint formed by the union of a cone-shaped bony process in the body socket.
