Articulations

Question 1

Articulations

Answer 1

Joints

Question 2

Synovial Joints

Answer 2

Bones surrounded by Articular capsule

Question 3

Fibrous Joints

Answer 3

Bones held together by fibrous connective tissue

Question 4

Cartilaginous Joints

Answer 4

Bones held together by cartilage

Question 5

Articular capsule

Answer 5

• A part of the Synovial joints

- surrounds joint and sets boundaries of synovial cavity between bones of the joint

Question 6

Fibrous Capsule

Answer 6

• most superficial layer of the Articular capsule
• attaches to the periosteum of the bone
• prevents bone from dislocating under normal stress

Question 7

Ligaments

Answer 7

Strong fibrous capsules found in some joints

Question 8

Synovial membrane

Answer 8

• deepest layer of Articular capsule

- secretes synovial fluid used to lubricate joint

Question 9

Articular discs

Answer 9

Pads of fibrocartilage between the bones of a joint, allows bones of different shapes to fit together tightly

Question 10

Bursae

Answer 10

Help reduce friction between joints and another structure

Question 11

Suture

Answer 11

Immovable fibrous joint with interlocking edges

Question 12

Syndesmosis

Answer 12

Joint where fibrous connective tissue forms a band between two bones That are farther apart than a suture

Question 13

Gomphosis

Answer 13

Ligament holds a peg-like structure in a socket

Question 14

Planar (synovial joints)

Answer 14

Two flat or slightly curved bone joints connecting

Question 15

Hinge (synovial joints)

Answer 15

Monoxial joint in Which bulging surface of one bone goes to concave surface

Ex: knee joint and elbow joint

Question 16

Pivot (synovial joint)

Answer 16

Cyndrical or pointed surface Of bone that rotates with an ring formed bone

Question 17

Condyloid (Synovial joint)

Answer 17

Two oval or convex portions of bones that fit into one another

Ex: phalanges

Question 18

Saddle (synovial joint)

Answer 18

To settle shaped parts of bone that fit into one another. Allows for up and down, and side to side movement

Question 19

Ball and socket (synovial joint)

Answer 19

Ball shaped part fits into socket like depression of another bone

Ex: Shoulder and hip joint

Question 20

Synchondrosis

Answer 20

Hyaline cartilage connecting 2 bones

Ex: first rib and sternum

Question 21

Symphasis

Answer 21

Phones along midline of the body are connected by thick pad of fibrocartilage along with a thin line of cartilage on each bone

Ex:Pubic and intravertebral joints between the parties of two vertebrae

Question 22

Flexion

Answer 22

Decreases the angle between the two bones of an articulation

Question 23

Extension

Answer 23

Increases the angle between the bones

Question 24

Hyper extension

Answer 24

Extending a joint beyond its normal anatomical position. Serious hyperextension may lead to strains and sprains

Question 25

Abduction

Answer 25

The movement of a limb away from the midline of the body in the frontal plane

Question 26

Adduction

Answer 26

Brings a limb back toward the midline of the body

Question 27

Circumduction

Answer 27

Movement that involves moving a set of bones so that it’s proximal end does not move and its distal demonstrate a circular motion

Question 28

Rotation

Answer 28

Movement of a bone around It’s longitudinal axis
